Holmberg IX is a tidal dwarf galaxy candidate that formed in a burst 130 million years ago but has since quenched star formation in its main body, appearing as a unique inactive young system.
Photometric study of Glimpse-C02 yields distance 6.3 kpc, age 11.9 Gyr, [Fe/H] = -0.30, and mass 3.57e4 solar masses, classifying it as an old metal-rich bulge globular cluster.
MWC 656 hosts a hot stripped star companion of 1.48 solar masses instead of a black hole.
Extended-image strong lensing model of cluster G165 reduces mass-parameter uncertainties by over an order of magnitude and maps dust extinction in the host of SN H0pe at z=1.78, finding A_V ≈ 0.9 mag near the explosion site.
The local Hubble constant is measured as 73.04 ± 1.04 km/s/Mpc from Cepheid-calibrated Type Ia supernovae, showing a 5-sigma discrepancy with the Planck+LCDM prediction.
Chandra spectra of GX 13+1 favor average-Galactic grain size distributions for interstellar dust, dominated by amorphous olivine with ~2% crystallinity and ruling out very diffuse or dense ISM scenarios.
VLBA observations of Orion young stellar binaries yield Keplerian orbits and dynamical masses for four systems, with two showing agreement to SED-based estimates and one confirming an intermediate-mass star with nonthermal emission.
Spectral monitoring indicates NGC 3786's changing-look AGN transition results from torus covering factor variations driven by Eddington ratio and accretion mode changes.
FUV imaging shows ongoing massive star formation in the extended low-density outskirts of NGC2090, with smaller complexes, rising specific SFR, and flux ratios consistent with a top-heavy IMF.
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.
654 WD-FGK binaries cataloged with mostly low-mass hot white dwarfs formed via binary interactions.
NOMAI applies XGBoost to SALT2 and Rainbow-derived features on ZTF alerts to reach 66% completeness and 58% purity for SLSNe, recovering 22 of 24 known active SLSNe in a two-month real-time test.
SPICY 97589 is an M3 star of 0.29 solar masses whose 2023 outburst was powered by an accretion rate of 2.38e-7 solar masses per year, two orders of magnitude above its quiescent level.
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.
