H I Absorbers as Beacons of Hidden Structure at z ~ 3: Multi-Component, Metal-Rich Absorption System near a Protocluster

Abstract H i gas traces the large-scale structure and provides the primary fuel for star formation. High-z protoclusters are ideal laboratories to study how H i gas is accreted and consumed during the formation of the most massive structures in the Universe. However, much remains...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...
