A 6D kinematic census identifies 18 anomalous Cepheids with extreme orbits, including one possibly scattered by globular cluster E3, and finds consistency between dynamical and stellar ages.
FIRE-2 simulations show per-galaxy tidal disruption rates peak near z=2.5 at 4e-4 per year, correlate with SFR and central density, and remain high in satellite galaxies at early times.
Kriging and Gaussian mixture modeling applied to HST data yield 1-pc resolution dust extinction maps in the SMC and LMC, showing log-normal column density distributions and systematic differences from FIR-derived dust masses.
An extended Lyα halo is detected around the z=6.64 BAL quasar J0910-0414, extending to 11 pkpc with rotation-like kinematics, lower velocity dispersion than the host core, and contributing 55% of the total Lyα flux due to central absorption.
JWST observations identify all massive young embedded star clusters in the Antennae, revealing they are extremely young, heavily obscured, and account for ~60% of the ionizing luminosity.
New JWST multi-filter imaging of Sgr B2 detects previously hidden massive stars and ionized structures while finding no extended young stellar objects, implying star formation there has only recently begun.
Multi-wavelength data on GRB 260310A support an off-axis jet model explaining weak prompt emission and bright delayed afterglow, including reverse-shock signatures and late X-ray rebrightening.
Spatially resolved JWST spectroscopy of M82 reveals an average ortho-to-para H2 ratio half the equilibrium value, attributed to short cloud mixing timescales relative to spin conversion and recent rapid heating.
First velocity-resolved [O I] 63/145 um maps of the Orion BN/KL outflow show broad components from dense warm postshock gas, with line ratios matching 30-40 km/s dissociative J-shocks illuminated by external UV, yielding [O I] luminosity 86.5 L_sun and mass-loss rate ~9e-3 M_sun/yr.
JWST observations resolve multiphase nuclear and kpc-scale outflows with velocities up to 520 km/s and PAH property gradients in the AGN-starburst composite ULIRG F10565+2448.
Discovery of a gravitationally lensed Type II supernova at z=1.37 with magnification ≳100×, confirmed via multi-telescope spectra and imaging.
First blind optical identification of a z=0.153 sub-luminous GRB afterglow with Ic-BL SN, yielding a volumetric rate consistent with on-axis high-luminosity long GRBs.
ATTILA tool identifies 24 new ultra-diffuse galaxies in Hydra I, doubling the known population to 48, plus 92 additional low surface brightness galaxies, while recovering over 80% of previously known ones.
A 6-arcsecond resolution extinction map of M33 derived from RGB star color fitting shows dust up to 2.5 mag aligned with hydrogen, HI, and CO distributions.
Spectroscopic survey of IC 1396 identifies 25 new brown dwarfs and measures a star-to-brown-dwarf ratio of 5.0±0.4 that is consistent with other young clusters.
Late-time JWST/NIRCam data on GRB 250702B show a high-mass dusty host and possible ~3-sigma transient detections in two bands suggesting light-curve flattening.
Analysis of ~600 RR Lyrae in DP1 shows PWZ-based distances match literature (mean offset 0.01 mag) while PLZ distances are systematically larger and amplitudes mismatch evolved models, due to limited light-curve sampling.
Discovery of an eclipsing neutron star LMXB with clocked bursts, orbital period 6.483 hr, companion mass 0.6-0.8 Msun, and helium burst indications from energy ratio 120-130.
No stellar flybys within the past 10 Myr and 500 pc in Gaia DR3 explain the present trajectory of 3I/ATLAS, which matches thin-disk kinematics despite its high peculiar velocity.
Review of UV spectroscopy applications to hot evolved stars, emphasizing HST contributions and the need for continued observations ahead of HWO.
