Perturbations of Einstein-Maxwell-phantom spacetime: Instabilities of charged Ellis wormholes and quasinormal modes of black holes
Phantom scalar fields, as a viable candidate for dark energy, have been instrumental in eliminating spacetime singularities and constructing wormholes and regular black holes. We investigate the Einstein-Maxwell-phantom (EMP) framework, in which the Ellis wormholes can be charged and regular black holes can be admitted. While the previous study has shown the stability of EMP wormholes under massless scalar field perturbations, we further perform a comprehensive linear analysis of the EMP spacet…

Neutrino oscillations in the Ellis wormhole spacetime
Gravitational lensing is a powerful tool to probe compact astrophysical objects and the distribution of dark matter at large scales. As a counterpart of photons, lensed relativistic neutrinos could also be used to explore properties of curved spacetimes. In the present paper we consider neutrino oscillations in the Ellis wormhole (WH) spacetime in comparison with the widely discussed black hole (BH) spacetimes. We investigate the oscillations involving lensing effects with 2- and 3-flavor neutr…

$β$-Ga$_2$O$_3$--Based Radiation Detector for Proton Therapy
Intensity modulated proton therapy (IMPT) is an advanced cancer treatment modality that offers significant advantages over conventional X-ray therapies, particularly in its ability to minimize radiation dose beyond the tumor target. This reduction in unnecessary irradiation exposure significantly lowers the risk to surrounding healthy tissue and reduces side effects compared to conventional X-ray treatments. However, due to the high complexity of IMPT plans, each plan must be independently vali…

Observing an accretion disk inside a wormhole shadow
The paper considers the problem of the possibility of observing an accretion disk through the throat of the Ellis-Bronnikov-Morris-Thorne wormhole. It is shown that this image has a complex structure and is fundamentally different from the image of an accretion disk around a black hole. Images of the accretion disk are presented at various angles between the plane of the disk and the observer's line of sight.

Convolution semigroups for automorphism dynamics
Initially motivated by Hrushovski's paper on definability patterns, we obtain homeomorphisms between Ellis semigroups related to natural actions of the automorphism groups of first order structures and certain collections of types and Keisler measures. Thus, we can transfer the semigroup operation from these Ellis semigroups to the corresponding collections of types and Keisler measures. By generalizing this transferred product, we obtain a new convolution operation for invariant types and meas…

Hierarchical Agglomerative Clustering (HAC) is an extensively studied and widely used method for hierarchical clustering in $\mathbb{R}^k$ based on repeatedly merging the closest pair of clusters according to an input linkage function $d$. Highly parallel (i.e., NC) algorithms are known for $(1+ε)$-approximate HAC (where near-minimum rather than minimum pairs are merged) for certain linkage functions that monotonically increase as merges are performed.

GeV-TeV Connections in Galaxies: Evolutionary Signatures from Pulsars in Globular Clusters
The dominant mechanisms underlying high-energy $γ$-ray emission from galaxies vary by galaxy type. In starbursts, a major contribution comes from neutral pion decay. This is driven by interactions between interstellar gas and hadronic cosmic rays (CRs), which are accelerated in strong shocks associated star formation activity and stellar remnants. Leptonic $γ$-ray emission can also arise from electrons directly energized in interstellar shocks, produced via charged pion decays, or emitted by …

Moment stability and large deviations for random dynamical systems on non-compact manifolds
The rate function for large deviations of the finite time Lyapunov exponent for the derived process in TM corresponding to a stochastic differential equation in M is related, via the Gartner-Ellis theorem, to the p-th moment Lyapunov exponent. When M is compact there is a characterization of the p-th moment Lyapunov exponent in terms of an eigenvalue problem for an associated differential operator acting on functions on the unit sphere bundle SM. For the non-compact case, we formulate growth co…

Derangements in permutation groups with two orbits
A classical theorem of Jordan asserts that if a group $G$ acts transitively on a finite set of size at least $2$, then $G$ contains a derangement (a fixed-point free element). Generalisations of Jordan's theorem have been studied extensively, due in part to their applications in graph theory, number theory and topology. We address a generalisation conjectured recently by Ellis and Harper, which says that if $G$ has exactly two orbits and those orbits have equal length $n \geq 2$, then $G$ conta…

The AURORA Survey: High-Redshift Empirical Metallicity Calibrations from Electron Temperature Measurements at z=2-10
We present detections of auroral emission lines of [OIII], [OII], [SIII], and [SII] in deep JWST/NIRSpec spectroscopy for 41 star-forming galaxies at $z=1.4-7.2$ from the AURORA survey. We combine these new observations with 98 star-forming galaxies at $z=1.3-10.6$ with detected auroral lines drawn from the literature to form a sample of 139 high-redshift galaxies with robust electron temperature and direct-method oxygen abundance determinations. This sample notably covers a wider dynamic range…

Strength in Numbers: Red Galaxies Bolster the Cosmic Star Formation Rate Density at z > 3
A comprehensive account of the cosmic star-formation history demands an accurate census of dust-enshrouded star formation over cosmic time. We provide strong new constraints from a large sample of 777 red galaxies, selected based on their dust-reddened, rest-frame UV-optical emission. This sample of 777 galaxies spans $1 < z < 8$ and is selected from PRIMER JWST NIRCam and HST COSMOS optical data, ensuring robust colour criteria. The SEDs indicate that these dust-reddened galaxies are star-form…
