Stars Can Quench Superradiance Around Supermassive Black Holes
Light scalar fields trigger an instability around rotating black holes which drives the rapid growth of high-density bound states on astrophysically short timescales---a phenomenon known as black…Equipartition between Alfvénic turbulence and energetic ions as the origin of the -5 common spectrum in the heliosphere
Suprathermal ion tails throughout the heliosphere follow a ``common spectrum,'' $f(v)\propto v^{-5}$.The Size-Mass Relation and Inside-Out Quenching of Massive Quiescent Galaxies at $2<z<3$ with JWST PRIMER and MINERVA
We investigate the morphology, size--mass relations, and spatially resolved star formation histories of 26 massive quiescent galaxies at cosmic noon ($2 < z < 3$) in the Ultra-Deep Survey field…Galaxy cluster thermodynamics at z=1.7: Resolved tSZ and X-ray analysis of CL J0459.6-4946
Measurements of the entropy and temperature distribution of the intracluster medium (ICM) of local clusters have proven pivotal for the study of cluster astrophysics.Turbulent gas-rich discs at high redshift: Chaotic orbits and rapid bulge formation at high gas fraction
Using the \nexus\ N-body/hydrodynamic framework, we show that stellar bars that emerge in high-redshift disc galaxies are different in their orbital characteristics compared to their low-redshift…Unveiling the Shock-Excited Molecular Environment in the Orion Protostar HOPS 370
We present near-infrared K-band ($1.94$--$2.52~μ$m) spectroscopy of the deeply embedded protostellar source HOPS\,370, obtained with the TIFR--ARIES Near Infrared Spectrometer (TANSPEC) on the 3.6-m…Age-Resolved Vertical Motions in the Milky Way Warp: A Localized Enhancement in Intermediate-Age Populations
Determining how the Milky Way warp evolves provides constraints on the formation and dynamical evolution of galactic disks.Numerical Simulations of the interaction between winds from tidal disruption event and supermassive black hole circumnuclear medium
The interaction between winds from tidal disruption event (TDE) and the circumnuclear medium (CNM) around supermassive black holes is believed to contribute to the radio emission of non-jetted TDEs.PyMsOfa 2.0: A Pure-Python Implementation of the IAU Standards of Fundamental Astronomy Service
Astrometric calculations require authoritative algorithms so that every result is correct and reproducible.Migration Traps as Variability Attractors. II. Nonmonotonic X-Ray Timing Signatures of Embedded Stellar-Mass Black Holes in AGN Disks
Stellar-mass black holes (sBHs) embedded in active galactic nucleus (AGN) disks may affect X-ray variability through magnetic reconnection.Nongravitational Motion of 3I/ATLAS Far from the Sun: Robust Detection, Weak Constraints on the Activity Law
3I/ATLAS provides an unprecedented astrometric data set for studying nongravitational (NG) effects in an interstellar object, but existing orbital solutions depend strongly on assumptions regarding…The Influence of Hubble Expansion on the Future Merger of the Milky Way and Andromeda
Most existing idealized simulations of galaxy mergers neglect Hubble expansion, as the local Hubble flow is curved by overdensities and the expansion effect is weak at these scales.Understanding the origin of silver in metal-poor stars based on the non-local thermodynamic equilibrium analysis of Ag I lines
Silver is a poorly observed neutron-capture element, and understanding its Galactic production history requires accurate abundances for stellar samples covering a broad metallicity range.GRAVITY-RESOLVE: A comprehensive image reconstruction tool for Galactic Center observations with GRAVITY
We aim to improve and extend the imaging capabilities of the GRAVITY beam combiner instrument of ESOs VLTI with respect to reconstruction software in the Galactic Center.Atmospheric Parameter Determination of RR Lyrae Stars With Mephisto Multi-band Photometry
Phase-resolved atmospheric parameters of pulsating stars, including RR Lyrae stars and Cepheids, are essential for studying stellar structure and pulsation physics and for establishing accurate…The nature of the Norma arm as a bar-driven star-forming shock front
The Milky Way is commonly depicted as having four major spiral arms, including the Norma-Outer arm, and a central stellar bar whose properties remain debated.Kinematic methods of spiral nature identification: limitations and applicability
The nature of spiral arms in galaxies remains debated, with several competing formation scenarios, including density waves, kinematic spirals, dynamic spirals, and recurrent modes, that are…Chemodynamical Study and Evidence for Hot Compact Companions to Blue Straggler Stars in Berkeley 31
We present a detailed study of the open cluster Berkeley 31 using Gaia DR3 astrometry, Gaia-ESO Survey DR5.1 spectroscopy, and multi-wavelength photometry.Black Hole Spin Evolution in Magnetized Accretion Flows
Black hole (BH) spin grows as accretion supplies angular momentum and decreases as magnetically driven jets remove it, driving the BH toward an equilibrium spin, $a_{\rm \star; eq}$.Infrared spectroscopy of the longest-period Galactic Mira variables from Palomar Gattini-IR: Identification of a candidate thermally pulsing Super-Asymptotic Giant Branch star
The population of extremely long-period Mira variables in the Milky Way remains poorly characterized.
