Multi-orbit S-star probes of Lorentz violation at the Galactic Center
We investigate the potential of Galactic-center S-star observations to probe Lorentz violation in the minimal pure-gravity Standard-Model Extension (SME), focusing on parameter degeneracies…Multiwavelength Classification of Chandra Sources in Omega Centauri
We present a comprehensive study of X-ray sources in the globular cluster NGC 5139 to date.The Milky Way's Early Disk Was Built in Bursts. II. The Multi-component Age-Metallicity Structure of the High-$α$ Disk
Whether the high-$α$ disk experienced a continuous or episodic star-formation history remains an open question.A 13 Year Black Hole Microlensing Survey in Omega Centauri
Star clusters are born with massive stars that leave behind a large population of stellar mass black holes.Lomb-Scargle Recovery of Periodic Binary Signals across Black Hole Mass and Cadence
Searches for periodic supermassive black hole binaries in quasar light curves rely on recovery fractions, the share of injected signals detected, which forecasts use as detection efficiencies.The ALMA-QUARKS survey: A Keplerian Circumbinary Disk Candidate in the High-mass Star-forming Region IRAS 08303-4303
We present the ALMA Band 6 continuum and molecular line observations of IRAS 08303-4303, a high-mass star-forming region, with an angular resolution of $\sim 0.3''$ ($\sim 700$ au at the distance of…A recurring changing state AGN discovered in the SAMI Galaxy Survey and SDSS
We present a detailed analysis of the AGN in galaxy J085337.26+014303.6 at z=0.0582.Discovering supernovae in the Virgo Cluster during the LSST era
In the era of unprecedentedly wide, deep and high-cadence sky surveys the chance for discovering new explosive transients in nearby, rich galaxy clusters within hours after explosion is expected to…A neural-network model to find correlations in astrochemical space
The detection of new interstellar molecules is central to astrochemistry, and arguably the most transformative development in the field in past decade has been the increase in both number and…Stability of rotation axis of galactic disks in HESTIA suite
We have found that in approximately 1/4 of Milky Way or M31 analogues in the HESTIA suite of simulations there is a significant, $>45^\circ$, change in the axis of rotation orientation of the…EP J062132.0+623837: A Multi-wavelength Study of a Changing-look Active Galactic Nucleus Discovered by Einstein Probe
EP J062132.0+623837 is a new X-ray source identified in 14-day binned survey data from the Wide-field X-ray Telescope aboard the Einstein Probe (EP).Self-Supervised Representation Learning for JWST Galaxy Images and Low Resolution Spectra
A self-supervised multimodal model recovers galaxy stellar masses from sparse JWST data that lack the multi-band coverage required by traditional SED fitting.A cosmic filament catalog for COSMOS-Web Data Release 1 across 0.5 < z < 3.5
Cosmic filaments represent the environments in which most galaxies form and evolve.The XMM-Newton view of the DEM L36 superbubble in the Large Magellanic Cloud
We present the first multi-wavelength analysis of the DEM L36 superbubble in the Large Magellanic Cloud.A Catalog of Spectral Properties for DESI DR1 Quasars
The Dark Energy Spectroscopic Instrument (DESI) is carrying out a five-year spectroscopic survey designed to map the large-scale structure of the Universe and obtain spectra for millions of galaxies…Slow Massive-Star Formation and the O-Star ZAMS Deficit
The scarcity of optically visible O stars near the theoretical zero-age main sequence (ZAMS) has puzzled astronomers for over four decades.SpecLess: A Multi Survey Python Package for Machine Learning Classification of Galaxy Morphology and Activity from Photometry
Broad band photometry enables scalable galaxy classification without spectroscopy at inference time, yet strong within survey performance may not transfer when the same galaxies are measured by…Some minimal characteristics and flat trajectories of a system in the N-body problem
For the classical model of a system of N particles with interaction (the N-body problem) we consider some spatial problems of nonlinear programming for finding conditional minima and local extrema…A Robust Estimator for the Lyman-$α$ Forest 1D Power Spectrum at High Redshift
The Lyman-$α$ (Ly$α$) forest flux power spectrum $P(k)$ is sensitive to a range of astrophysical and cosmological effects, including the thermal state of and large-scale fluctuations in the…Odd radio circle J1555+2726: Observational evidence for shock re-acceleration of fossil plasma
Odd radio circles (ORCs) are peculiar extragalactic sources recently discovered.
