Measurement of coherent exclusive $J/ψ\toμ^+μ^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV with the ATLAS detector
The ATLAS experiment has performed a measurement of coherent exclusive $J/ψ\toμ^+μ^-$ production in ultraperipheral Pb+Pb collisions at $\sqrt{s_{\textrm{NN}}}=5.36$ TeV. The data was recorded at the Large Hadron Collider (LHC) during 2023, and corresponds to an integrated luminosity of 78 $μ$b$^{-1}$. Exclusive $J/ψ$ candidates were selected with a dedicated track-sensitive trigger based on the ATLAS transition radiation tracker. The analysis involves reconstruction of the dimuon invarian…

Distance restricted matching extensions in regular non-bipartite graphs
Let $m$ and $r$ be integers with $m \ge r \ge 3$ and let $G$ be an $r$-regular graph of even order. Let $M$ be a matching in $G$ of size $m$ such that each pair of edges in $M$ is at distance at least $3$. In 2023, Aldred et al. proved that if $G$ is cyclically $(mr-r+1)$-edge-connected and $G$ is bipartite, then there exists a perfect matching of $G$ containing $M$. In this paper, we present non-bipartite analogues of Aldred et al.'s theorem. An odd ear of $U \subseteq V(G)$ is a path of odd l…

Classical density functional theory for nanoparticle-laden droplets
Droplets of a pure fluid, such as water, in an open container surrounded by gas, are thermodynamically unstable and evaporate quickly. In a recent paper [Archer et al. J. Chem. Phys. {\bf 159}, 194403 (2023)] we employed lattice density functional theory (DFT) to demonstrate that nanoparticles or solutes dissolved in a liquid droplet can make it thermodynamically stable against evaporation. In this study, we extend our model by using continuum DFT, which allows for a more accurate description o…

Energy Confinement Time Scaling for the Negative Triangularity Scenario in DIII-D
Results from the 2023 negative triangularity campaign on DIII-D demonstrate encouraging energy confinement properties, similar to or exceeding the scaling of the IPB98(y,2) law. This paper describes the procedure with which a new scaling law was regressed specifically from the data from the DIII-D campaign. Given the relatively small size of the single-machine dataset, measures were taken to minimize sampling bias and give a realistic estimate of the large uncertainties from the regression. The…

Cohort-Anchored Robust Inference for Event-Study with Staggered Adoption

Cohort-Anchored Robust Inference for Event-Study with Staggered Adoption
I propose a cohort-anchored framework for robust inference in event studies with staggered adoption. Robust inference based on aggregated event-study coefficients, as in Rambachan and Roth (2023), can be misleading because pre- and post-treatment coefficients are identified from different cohort compositions and the not-yet-treated control group changes over time. To address these issues, I work at the cohort-period level and introduce the \textit{block bias}-the parallel-trends violation for a…

T CrB - overview of the accretion history, Roche-lobe filling, orbital solution, and radiative modeling: #TCrB are mounting, initiated by the discovery in 2015 of a new enhanced mass-transfer phase (SAP), which is reminiscent of the one preceding the last recorded outburst in 1946. [...] SAP has been caused by an inside-out collapse of the disk, during which the mean accretion rate onto the WD has been ~28x larger than in quiescence. SAP ended in April 2023, but from May 2024 mass-flow has intensively resumed at disk inner radii while the collapse wave reached the outer portions of the disk; the consequent revamp in mass accretion could fill the gap inherited by the fainter 2015-2023 SAP and eventually lead the WD accreted shell to ignition."

Day 3: Octavia Butler.
Incredibly dark, graphic, and disturbing near-future science fiction, which has proved absolutely prophetic. In the 1990's she was writing about a charismatic Conservative Christian and white nationalist president elected in 2024, and the horrors his paramilitary followers would unleash, including forced labor & indoctrination camps. Did I mention those books include ebikes & pseudo-cellphones too? Characters fleeing north from a disastrous social collapse in Loss Angeles? This is "The Parable of the Sower" and "The Parable of the Talents" and the later was tragically rushed to an end because of Butler's declining health.
Her work deals unflinchingly with racism and the darker parts of society, and to those who might say "her depiction of social collapse is overblown," I'd say that while it's not literally the world we live in, it's *effectively* the world that the poorest of us live in. If you're a homeless undocumented latinx person in LA right now, I'm not sure how meaningfully different your world is from the one she depicts.
Her work comes with a strong content warning for lots of things, including racial violence, sexual abuse and slavery, including of children, animal harm, etc., so it's not for everyone. Reading it in 2023 was certainly an incredible trip. Her politics are really cool though; with explicit pro-LGBTQ themes and tinges of what might today be considered #SolarPunk.

All-sky search for long-duration gravitational-wave transients in the first part of the fourth LIGO-Virgo-KAGRA Observing run
We present an all-sky search for long-duration gravitational waves (GWs) from the first part of the LIGO-Virgo-KAGRA fourth observing run (O4), called O4a and comprising data taken between 24 May 2023 and 16 January 2024. The GW signals targeted by this search are the so-called "long-duration" (> 1 s) transients expected from a variety of astrophysical processes, including non-axisymmetric deformations in magnetars or eccentric binary coalescences. We make minimal assumptions on the emitted GW …

Accurate complex-stacking-fault Gibbs energy in Ni3Al at high temperatures
To gain a deeper insight into the anomalous yield behavior of Ni3Al, it is essential to obtain temperature-dependent formation Gibbs energies of the relevant planar defects. Here, the Gibbs energy of the complex stacking fault (CSF) is evaluated using a recently proposed ab initio framework [Acta Materialia, 255 (2023) 118986], accounting for all thermal contributions - including anharmonicity and paramagnetism - up to the melting point. The CSF energy shows a moderate decrease from 300K to abo…

Spectral extrema of graphs of given even size forbidding H(4,3)
A graph is sad to be $H$-free if it does not contain $H$ as a subgraph. Let $H(k,3)$ be the graph formed by taking a cycle of length $k$ and a triangle on a common vertex. Li, Lu and Peng [Discrete Math. 346 (2023) 113680] proved that if $G$ is an $H(3,3)$-free graph of size $m \geq 8$, then the spectral radius $ρ(G) \leq \frac{1+\sqrt{4 m-3}}{2}$ with equality if and only if $G \cong S_{\frac{m+3}{2}, 2}$, where $S_{\frac{m+3}{2}, 2}=K_2 \vee \frac{m-1}{2}K_1$. Note that the bound is attainab…

Magnetic Reconnection as a Potential Driver of X-ray Variability in Active Galactic Nuclei
We present a systematic analysis on the X-ray variability in 13 bright quasars at z > 4.5, combining recent Swift observations from 2021 to 2023 and archival multi-epoch observations. Upper limits of the luminosity measurements were included in the analysis by using the Kaplan-Meier estimator method. It is found that the high-z quasars exhibit X-ray variability on both short-term (hours-to-days) and intermediate-term (weeks-to-months) timescales, with short-term variability dominating the overa…

Convergence of a finite-volume scheme for aggregation-diffusion equations with saturation
In [Bailo, Carrillo, Hu. SIAM J. Appl. Math. 2023] the authors introduce a finite-volume method for aggregation-diffusion equations with non-linear mobility. In this paper we prove convergence of this method using an Aubin--Simons compactness theorem due to Gallouët and Latché. We use suitable discrete $H^1$ and $W^{-1,1}$ discrete norms. We provide two convergence results. A first result shows convergence with general entropies ($U$) (including singular and degenerate) if the initial datum d…

Search for Neutrino Counterparts to Gravitational Wave Events in Super-Kamiokande during the LIGO/Virgo/KAGRA O4 Observing Run
In recent years, the Super-Kamiokande (SK) experiment has contributed to multi-messenger astronomy by searching for neutrino signals in coincidence with gravitational wave events. The fourth observing run (O4) of the LIGO/Virgo/KAGRA collaborations started in May 2023. During the initial phase, known as O4a, LIGO identified 81 gravitational wave candidates. Neutrino follow-up searches with O4a were performed in SK. While no significant signal was observed, flux limits were computed.

Localized and weighted versions of extremal problems
Malec and Tompkins (EUJC, 2023) considered the localized versions of Turán-type problems, and proved a localized theorem on Erdős-Gallai Theorem on paths. Zhao and Zhang (JGT, 2025) gave a long proof of a localized version of Erdős-Gallai Theorem on cycles. In this paper, we consider several types of generalization of Turán-type problems, that is, localized versions, weighted versions, and generalized Turán-type problems, and their connectedness. We first present very short proofs for re…

Propeller effect in action: unveiling quenched accretion in the transient X-ray pulsar 4U 0115+63
The Be/X-ray pulsar 4U 0115+63 underwent a type II outburst in 2023. After the outburst, similar to the outbursts in 2015 and 2017, the source decayed into a quiescent state. Two out of three XMM-Newton observations conducted after the 2023 outburst confirmed the source to be in a low-luminosity state at a level of $L_{\rm X} \sim 10^{33}\,\rm erg\,s^{-1}$. X-ray pulsations were detected at $\approx$0.277 Hz in both observations with a pulsed fraction exceeding 50%. The power density spectra sh…

"Industrial-Scale" Black Hole Selection without a Satellite
The forthcoming GRAVITY+ instrument promises to usher in an era of "industrial-scale" mass measurements of isolated black holes (BHs), with the potential to assemble a sample of many tens of BHs via interferometric microlensing over several years. A key challenge will be selecting interferometric follow-up targets from an order-of-magnitude larger pool of ongoing microlensing events when using traditional selection based on event timescale alone. Gould (2023) proposed a criterion optimized for …

Unprecedentedly bright X-ray flaring in Cygnus X-1 observed by INTEGRAL
We study three extraordinarily bright X-ray flares originating from Cyg X-1 seen on 2023 July 10 detected with INTEGRAL. The flares had a duration on the order of only ten minutes each, and within seconds reached a 1-100 keV peak luminosity of $1.1-2.6\times10^{38}$ erg/s. The associated INTEGRAL/IBIS count rate was about ${\sim}$10x higher than usual for the hard state. To our knowledge, this is the first time that such strong flaring has been seen in Cyg X-1, despite the more than 21 years of…

In this paper, we carry out multiwavelength observations of simultaneous longitudinal and transverse oscillations of a quiescent filament excited by an extreme-ultraviolet (EUV) wave on 2023 February 17. A hot channel eruption generates an X2.3 class flare and a fast coronal mass ejection (CME) in active region (AR) NOAA 13229 close to the eastern limb. The CME drives an EUV wave, which propagates westward at a speed of ~459 km s-1. After arriving at the filament ~340.3 Mm away from the flare s…

Non-r-partite graphs without complete split subgraphs
The classical Simonovits' chromatic critical edge theorem shows that for sufficiently large $n$, if $H$ is an edge-color-critical graph with $χ(H)=p+1\ge 3$, then the Turán graph $T_{n,p}$ is the unique extremal graph with respect to ${\rm ex}(n,H)$. Denote by ${\rm EX}_{r+1}(n,H)$ and ${\rm SPEX}_{r+1}(n,H)$ the family of $n$-vertex $H$-free non-$r$-partite graphs with the maximum size and with the spectral radius, respectively.
