A ~40 solar-mass protostar in Sgr C is surrounded by a Keplerian disk of centrifugal radius 1300 au, free-falling streamers, and an envelope accretion rate of 7e-3 solar masses per year.
VERSUS is a void-finding algorithm that identifies spherical underdensities matching excursion-set predictions for the void size function, validated on synthetic particles and AbacusSummit mocks with realistic galaxy populations.
Satellite anisotropy transitions from central galaxy morphology below 0.3 R_200c to halo triaxiality between 0.3-2 R_200c to filament alignment beyond 2 R_200c, with kinematic origins shown by trajectory analysis in SIMBA.
An accelerating plasma blob crossing the BLR in 3C 279 reproduces the 2013 orphan gamma-ray flare's hard spectrum, rapid rise, slow decay, and lack of optical variability via varying external Compton scattering.
A new catalogue of bar lengths and widths from HST images of 8230 galaxies shows bars are about 13% weaker at higher redshift, with longer bars in higher-mass quiescent galaxies and trends consistent with slow quenching.
Resolved gas and dust maps in a z=2 quiescent galaxy reveal accreted material from tidal interactions and a past star-formation rejuvenation, indicating that gas content variations are not solely due to consumption timescales.
Exhaustive symbolic regression identifies low-complexity functional forms for luminosity and mass functions that outperform Schechter and Press-Schechter parametrizations while satisfying physical extrapolation and integration constraints.
Little Red Dots show soft ionizing spectra consistent with massive stars, based on high H-alpha EWs and low HeII/H-beta ratios that rule out hard AGN spectra via Cloudy modeling.
Spatially resolved observations of z~0.1 galaxies show Mg II absorption outflow velocities are systematically higher than Hα emission velocities by ~0.4 dex while maintaining similar correlations with star formation rate and surface density.
Low-luminosity AGN exhibit optical variability structure function slopes that increase with black hole mass from ~0.1 to ~0.3, with amplitude anticorrelated with luminosity, no breaks observed, and variability continuing to rise on 20-year timescales.
A simulation study finds that a hot gas halo at galaxy total mass ~10^12.5 solar masses suppresses cool gas accretion, driving a redshift-independent turnover in the stellar-to-total mass ratio via reduced in-situ star formation efficiency.
The Milky Way stellar disk shows a broken radial density profile with four components, azimuthal dependence, inner and outer flaring, and a density-metallicity bump possibly from radial migration.
The UV luminosity function at z~7 rises steeply with slope alpha=-1.98 to M_UV=-12.3 with no turnover, indicating faint galaxies dominate the ionizing photon budget during reionization.
SCAT DR1 delivers 1810 spectra of 1330 transients with classifications, fitted light curves, new redshifts for many host galaxies, and host properties as a testbed for photometric classification pipelines.
SN 2020aze displays early He II emission from ejecta-CSM interaction, a steep V-band decline, and semi-analytical modeling yields a ~14 solar-mass red supergiant progenitor with ~12 solar-mass ejecta and 1.5e51 erg explosion energy.
VLA L-band polarization observations of SNR G7.7-3.7 show cocoon morphology from interaction with pre-existing circumstellar shells, with magnetic fields compressed along filaments and RM variations tracing massive progenitor winds.
Pulsar radio emission beams from the two poles are generally dissimilar in azimuth width and often radius, based on rotating vector model fits to polarization data from eight double-pole interpulse pulsars.
Asteroseismic modeling of RY Leporis gives a mass of ~2 solar masses and age of ~730 Myr, locating it in the post-main-sequence hydrogen shell-burning stage with consistent metallicity.
Inertial Alfvén waves exert ponderomotive force that redistributes plasma density and suppresses rotation measure, explaining short-term RM substructures in active repeating FRBs.
Early kinematically persistent planes of satellite galaxies are fossil remnants of high-redshift anisotropic mass collapse along the principal directions of the local cosmic web during the fast assembly phase of host halos.
A scaling law for nonthermal power-law tails in magnetized turbulent plasmas is derived from particle transport principles and confirmed by PIC simulations with escape, with applications to black hole coronae.
Multi-technique timing analysis indicates a ~478-day QPO in the gamma-ray emission of BL Lac GB6 J1037+5711.
JWST/MIRI imaging of Eps Ind A b prefers a double-PSF model likely due to systematics but demonstrates sensitivity to exomoons down to 1.3 M_Jup at separations >2 AU and 2.5 M_Jup at 0.52 AU.
