Judge Cannon shoots down Trump’s presidential records act claim
U.S. District Judge Aileen M. Cannon on Thursday rejected Donald Trump’s bid to have his charges of mishandling classified documents dismissed on the grounds that a federal records law protected him from prosecution.

The judge also defended her handling of the issue, which had surprised legal experts and rankled prosecutors.

Trump’s defense team argued that the Presidential Records Act (PRA) took priority ove…

Regge trajectory relations for the universal description of the heavy-light systems: diquarks, mesons, baryons and tetraquarks
Two newly proposed Regge trajectory relations are employed to analyze the heavy-light systems. One of the relations is $M=m_1+m_2+C'+β_x\sqrt{x+c_{0x}}$, $(x=l,\,n_r)$. Another reads $M=m_1+C'+\sqrt{β_x^2(x+c_{0x})+\frac{4}{3}\sqrt{π{β_x}}m^{3/2}_2(x+c_{0x})^{1/4}}$. $M$ is the bound state mass. $m_1$ and $m_2$ are the masses of the heavy constituent and the light constituent, respectively. $l$ is the orbital angular momentum and $n_r$ is the radial quantum number. $β_x$ and $c_{0x}$ are f…

It’s rare you get a chance to ask a Minister of a government a question (even indirectly through a radio show).
I'm happy I got that chance last Thursday. You can listen below. (Start from 2:36 if you'd like to skip some).
The BC Minister of Post-Secondary says a lot of platitudes and half-truths about increases in ‘operating grants’ and capital funding. Fact is: School is more expensive than ever and institutions and students are struggling.

#RustLang is the perfect language for the "move fast, break things" era. No, I'm not implying it encourages you to break stuff. All I'm saying is that all these modern languages are specifically designed for that mindset. They optimize for corporate greed — nicely dressed as "valuing developer's time".
Developers aren't supposed to slow down and think things over. They should finish feature after feature, project after project, profit after profit. When things break, that's bad for profit. However, putting an effort to prevent things from breaking is not cost-effective.
People love to point out memory safety problems with C. However, there are two other important problems affecting C libraries — ABI and API stability. An uncontrolled ABI breakage means that existing programs suddenly breaks. An uncontrolled API breakage means that programs don't build anymore. Combine both and you're in a tight fit.
There are reasonably good solutions to both these problems. However, they require conscious effort, they require thinking — and that is costly. There are also cheap workarounds. If you link libraries statically, you don't need to worry about their ABI changes. If you vendor dependencies, you don't even need to worry about API changes. That's much cheaper for the company — though in reality, it just moves the burden down the line, to distribution developers and users, who end up fighting old, broken or even vulnerable vendored dependencies.
The problem with Rust and #Cargo is that it embraces these hacks into glorified 20M executables. Everything is linked statically, everything is vendored. You can move fast without actually breaking things — at least for the significant majority of users. To the minority, you always have the usual excuse — "we're sorry, we're just volunteers, we can't spend more energy on this, and you should get newer hardware anyway". Not that doing things better wouldn't benefit all users.

Fires in the deep: The luminosity distribution of early-time gamma-ray-burst afterglows in light of the Gamow Explorer sensitivity requirements
Gamma-ray bursts (GRBs) are ideal probes of the Universe at high redshift (z > 5), pinpointing the locations of the earliest star-forming galaxies and providing bright backlights that can be used to spectrally fingerprint the intergalactic medium and host galaxy during the period of reionization. Future missions such as Gamow Explorer are being proposed to unlock this potential by increasing the rate of identification of high-z GRBs to rapidly trigger observations from 6-10 m ground telescopes,…

The supermassive black holes ($M_{\rm BH} \sim 10^{6}$$-$$10^{10}~M_\odot$) that power luminous active galactic nuclei (AGNs), i.e., quasars, generally show a correlation between thermal disk emission in the ultraviolet (UV) and coronal emission in hard X-rays. In contrast, some "massive" black holes (mBHs; $M_{\rm BH} \sim 10^{5}$$-$$10^{6}~M_\odot$) in low-mass galaxies present curious X-ray properties with coronal radiative output up to 100$\times$ weaker than expected.

The matched projections of idempotents on Hilbert $C^*$-modules
The aim of this paper is to give new characterizations of some fundamental issues about idempotents. In the general setting of adjointable operators on Hilbert $C^*$-modules, a new term of quasi-projection pair is introduced. For each idempotent $Q$, a projection $m(Q)$, called the matched projection of $Q$, is constructed. It is shown that $Q$ and $m(Q)$ as idempotents are homotopic, and $\big(m(Q),Q\big)$ is a quasi-projection pair. Some formulas for $m(Q)$ are derived. Based on these formula…

We consider (non-necessarily free) actions of subgroups $H\subset \mathbb Z_2^m$ on the real moment-angle manifold $\mathbb R\mathcal{Z}_P$ corresponding to a simple convex $n$ polytope $P$ with $m$ facets. The criterion when the orbit space $\mathbb R\mathcal{Z}_P/H$ is a topological manifold (perhaps with a boundary) can be extracted from results by M.A. Mikhailova and C. Lange. For any dimension $n$ we construct series of manifolds $\mathbb R\mathcal{Z}_P/H$ homeomorphic to $S^n$ and series …

On manifolds with nonnegative Ricci curvature and the infimum of volume growth order $<2$
We prove two rigidity theorems for open (complete and noncompact) $n$-manifolds $M$ with nonnegative Ricci curvature and the infimum of volume growth order $<2$. The first theorem asserts that the Riemannian universal cover of $M$ has Euclidean volume growth if and only if $M$ is flat with an $n-1$ dimensional soul. The second theorem asserts that there exists a nonconstant linear growth harmonic function on $M$ if and only if $M$ is isometric to the metric product $\mathbb{R}\times N$ for some…

Polarimetric differential imaging with VLT/NACO. A comprehensive PDI pipeline for NACO data (PIPPIN)
The observed diversity of exoplanets can possibly be traced back to the planet formation processes. Planet-disk interactions induce sub-structures in the circumstellar disk that can be revealed via scattered light observations. However, a high-contrast imaging technique such as polarimetric differential imaging (PDI) must first be applied to suppress the stellar diffraction halo. In this work we present the PDI PiPelIne for NACO data (PIPPIN), which reduces the archival polarimetric observation…

Nikki Haley won her first contest in the Republican presidential nomination race on Sunday after triumphing in Washington, D.C.'s primary.
(It won’t likely change the contest’s trajectory.)

After three days of voting, polls in the Washington race closed at 7 p.m. Eastern on Sunday.
Though only 19 delegates were stake, Haley perhaps had her best chance of defeating Trump in a race where he performed poorly in the last competitive GOP presidential contest in 2016.

Unlike Trump, Haley campaigned in Washington ahead of the primary, visiting the city on Friday.

Ongoing and upcoming galaxy redshift surveys, such as the Dark Energy Spectroscopic Instrument (DESI) survey, will observe vast regions of sky and a wide range of redshifts. In order to model the observations and address various systematic uncertainties, $N$-body simulations are routinely adopted, however, the number of large simulations with sufficiently high mass resolution is usually limited by available computing time. Therefore, achieving a simulation volume with the effective statistical …

Winding number and circular 4-coloring of signed graphs
Concerning the recent notion of circular chromatic number of signed graphs, for each given integer $k$ we introduce two signed bipartite graphs, each on $2k^2-k+1$ vertices, having shortest negative cycle of length $2k$, and the circular chromatic number 4. Each of the construction can be viewed as a bipartite analogue of the generalized Mycielski graphs on odd cycles, $M_{\ell}(C_{2k+1})$. In the course of proving our result, we also obtain a simple proof of the fact that $M_{\ell}(C_{2k+1})…

NGTS-30 b/TOI-4862 b: An 1 Gyr old 98-day transiting warm Jupiter
Long-period transiting exoplanets bridge the gap between the bulk of transit- and Doppler-based exoplanet discoveries, providing key insights into the formation and evolution of planetary systems. The wider separation between these planets and their host stars results in the exoplanets typically experiencing less radiation from their host stars; hence, they should maintain more of their original atmospheres, which can be probed during transit via transmission spectroscopy. Although the known po…

Parameters of the tensor tetraquark $bb\overline{c}\overline{c}$
The mass and width of the tensor tetraquark $T=bb\overline{c}\overline{c}$ with spin-parity $J^{\mathrm{P}}=2^{+}$ are calculated in the context of the QCD sum rule method. The tetraquark $T$ is modeled as a diquark-antidiquark state built of components $b^{T}Cγ_{μ}b$ and $\overline{c}γ_{ν}C\overline{c}^{T}$ with $C$ being the charge conjugation matrix. The mass $m=(12795\pm 90)~\mathrm{MeV}$ of the exotic tensor meson $T$ is found by means of the two-point sum rule approach. Its full width…

Full orbital solutions in pre-main sequence high-order multiple systems: GG Tau Ab and UX Tau B
High-order multiple (triple and beyond) systems are relatively common. Their interaction with circumstellar and circumbinary material can have a large impact on the formation and evolution of planetary systems and depends on their orbital properties. GG\,Tau and UX\,Tau are two pre-main sequence high-order multiple systems in which the tightest pair has a projected separation of $\approx5$--20\,au. Characterizing precisely their orbits is crucial to establish their long-term stability, to predi…

A possible interaction between cold dark matter and dark energy, corresponding to a well-known interacting dark energy model discussed in the literature within the context of resolving the Hubble tension, has been investigated. We put constraints on it in a novel way, by creating new likelihoods with an analytical marginalization over the Hubble parameter $H_0$, the sound horizon $r_d$, and the supernova absolute magnitude $M_B$. Our aim is to investigate the impacts on the coupling parameter o…

On 5-cycles and strong 5-subtournaments in a tournament of odd order n
Let $T$ be a tournament of odd order $n\ge 5,$ $c_{m}(T)$ be the number of its $m$-cycles, and $s_{m}(T)$ be the number of its strongly connected $m$-subtournaments. Due to work of L.W. Beineke and F. Harary, it is well known that $s_{m}(T)\le s_{m}(RLT_{n}),$ where $RLT_{n}$ is the regular locally transitive tournament of order $n.$ For $m=3$ and $m=4,$ $c_{m}(T)$ equals $s_{m}(T),$ but it is not so for $m\ge 5.$ As J.W. Moon pointed out in his note in 1966, the problem of determining the maxi…

3D scaling laws and projection effects in The300-NIKA2 Sunyaev-Zeldovich Large Program Twin Samples
The abundance of galaxy clusters with mass and redshift is a well-known cosmological probe. The cluster mass is a key parameter for studies that aim to constrain cosmological parameters using galaxy clusters, making it critical to understand and properly account for the errors in its estimates. Subsequently, it becomes important to correctly calibrate scaling relations between observables like the integrated Compton parameter and the mass of the cluster. The NIKA2 Sunyaev-Zeldovich Large prog…

A 'MeerKAT-meets-LOFAR' study of the complex multi-component (mini-)halo in the extreme sloshing cluster Abell 2142
Clusters of galaxies are turbulent environments, whether merging systems with a turbulent intracluster medium (ICM) or relaxed systems sloshing within the potential well. In many such clusters, diffuse radio sources associated with the ICM are found: radio haloes and mini-haloes. Abell 2142 is a rich cluster undergoing extreme core sloshing, generating four cold fronts and a complex multi-component radio halo. Recent work revealed three halo components which span 2.4 Mpc. Particle acceleration …

Mass calibration of DES Year-3 clusters via SPT-3G CMB cluster lensing
We measure the stacked lensing signal in the direction of galaxy clusters in the Dark Energy Survey Year 3 (DES Y3) redMaPPer sample, using cosmic microwave background (CMB) temperature data from SPT-3G, the third-generation CMB camera on the South Pole Telescope (SPT). We estimate the lensing signal using temperature maps constructed from the initial 2 years of data from the SPT-3G 'Main' survey, covering 1500 deg$^2$ of the Southern sky. We then use this signal as a proxy for the mean cluster…

Validation of the DESI 2024 Ly$α$ forest BAO analysis using synthetic datasets
The first year of data from the Dark Energy Spectroscopic Instrument (DESI) contains the largest set of Lyman-$α$ (Ly$α$) forest spectra ever observed. This data, collected in the DESI Data Release 1 (DR1) sample, has been used to measure the Baryon Acoustic Oscillation (BAO) feature at redshift $z=2.33$. In this work, we use a set of 150 synthetic realizations of DESI DR1 to validate the DESI 2024 Ly$α$ forest BAO measurement. The synthetic data sets are based on Gaussian random fields usin…
