XRF 241001A is a low-luminosity collapsar event with a broad-line Type Ic supernova, supporting XRFs as the faint end of the long GRB population observed on-axis by a weak jet.
Speckle imaging of 81 RR Lyrae stars detects 10 likely bound companions at 20-220 AU separations, yielding a binary fraction estimate above 12 percent.
A ~1 solar-mass main-sequence star with supersolar metallicity has been traced back to the galactic center as a hypervelocity star ejected by the Hills mechanism.
Three new candidate ancient planetary nebulae, each several arcminutes across with extremely low [O iii] surface brightness around 30 mag arcsec^{-2}, were discovered using amateur telescopes, with candidate central stars yielding age estimates of 50-100 thousand years.
Type Ic core-collapse supernovae explode in systematically younger environments than Types II, IIb, and Ib, indicating they arise from more massive progenitors via a distinct channel.
New LOFAR radio data and X-ray modeling indicate the extended source is thermal ICM emission from a massive merging galaxy cluster, unrelated to 1LHAASO J0343+5254u.
Planar very metal-poor stars exhibit chemical homogeneity and dwarf-galaxy-like abundance ratios, supporting origin from one ancient accreted system tentatively called Loki.
Euclid identifies 16 massive compact galaxies with V-shaped SEDs at z>4, half as old as the universe at their redshift, mostly distinct from known AGN.
AT 2025abao is the fourth LRN in M31, showing a plateau light curve, canonical spectroscopic evolution from hot continuum with Balmer lines to cool molecular bands, and an AGB progenitor whose IR SED is reported for the first time.
Strong blended Lyα absorbers cluster with Lyα emitting galaxies at z>3 within 300 kpc and 300 km/s, confirming they trace the circumgalactic medium interface.
ELEPHANT flags hostless transients from ZTF alerts with 0.84 accuracy, confirming 67 genuine cases mostly as Type Ia supernovae from 877 candidates between 2023 and 2025.
Observations show a slight rise in stripped-envelope supernovae relative to hydrogen-rich ones at higher metallicities, with binary-interaction or rotation models able to match the trends though no unique scenario fits best.
Barred galaxies with residual central emission and NUV-r color transition at the bar end represent an intermediate evolutionary phase in bar-driven quenching before full central quenching.
New optical identifications and precise astrometry are reported for four quiescent black hole X-ray transients, with 3-sigma magnitude limits for five additional candidates.
SN 2020lao reached a specific kinetic energy of 5-7 x 10^51 erg per solar mass typical of engine-driven events yet showed no afterglow or excess emission, implying any jet was off-axis, choked, or absent.
