First joint absorption and T-based metallicity measured in a GRB host galaxy at using JWST/NIRSpec
Anne Inkenhaag, Patricia Schady, Phil Wiseman +20
We present the first gamma-ray burst (GRB) host galaxy with a measured absorption line and electron temperature (T) based metallicity, using the temperature sensitive [OIII]…
First IFU observations of two GRB host galaxies at cosmic noon with JWST/NIRSpec
B. Topçu, P. Schady, S. Wuyts +16
Long gamma-ray bursts (GRBs) serve as powerful probes of distant galaxies. Their luminous afterglow pinpoints galaxies independent of luminosity, in contrast to most flux-limited s…
Local starburst conditions and formation of GRB 980425 / SN 1998bw within a collisional ring
M. Arabsalmani, F. Renaud, S. Roychowdhury +9
We present the first spatially resolved study of molecular gas in the vicinity of a Gamma Ray Burst, using CO(2-1) emission line observations with the Atacama Large Millimetre Arra…
The host galaxy of GRB 980425 / SN1998bw: a collisional ring galaxy
M. Arabsalmani, S. Roychowdhury, T. K. Starkenburg +8
We report Giant Metrewave Radio Telescope (GMRT) , Very Large Telescope (VLT) and Spitzer Space Telescope observations of ESO 184G82, the host galaxy of GRB 980425/SN 1998bw, th…
The 2175 Å extinction feature in the optical afterglow spectrum of GRB 180325A at z=2.25
T. Zafar, K. E. Heintz, J. P. U. Fynbo +26
The UV extinction feature at 2175 Å is ubiquitously observed in the Galaxy but is rarely detected at high redshifts. Here we report the spectroscopic detection of the 2175 Å bump o…
Mass and metallicity scaling relations of high redshift star-forming galaxies selected by GRBs
M. Arabsalmani, P. Møller, D. A. Perley +19
We present a comprehensive study of the relations between gas kinematics, metallicity, and stellar mass in a sample of 82 GRB-selected galaxies using absorption and emission method…
