Multiwavelength properties of short gamma ray bursts with extended emission observed by Swift

M. M. Dinatolo, A. Mei, R. Brivio +11

Short gamma-ray bursts with extended emission (SGRBEEs) are a particular class of long GRBs (LGRBs) which, despite their duration, share several observational features with short G…

Swift-BAT GUANO follow-up of gravitational-wave triggers in the third LIGO-Virgo-KAGRA observing run

Gayathri Raman, Samuele Ronchini, James Delaunay +1819

We present results from a search for X-ray/gamma-ray counterparts of gravitational-wave (GW) candidates from the third observing run (O3) of the LIGO-Virgo-KAGRA (LVK) network usin…

Comparing emission- and absorption-based gas-phase metallicities in GRB host galaxies at using JWST

P. Schady, R. M. Yates, L. Christensen +34

Much of what is known of the chemical composition of the universe is based on emission line spectra from star forming galaxies. Emission-based inferences are, nevertheless, model-d…

JWST detection of heavy neutron capture elements in a compact object merger

A. Levan, B. P. Gompertz, O. S. Salafia +80

The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…

Swift/UVOT discovery of Swift J221951-484240: a UV luminous ambiguous nuclear transient

S. R. Oates, N. P. M. Kuin, M. Nicholl +57

We report the discovery of Swift J221951-484240 (hereafter: J221951), a luminous slow-evolving blue transient that was detected by the Neil Gehrels Swift Observatory Ultra-violet/O…

The first JWST spectrum of a GRB afterglow: No bright supernova in observations of the brightest GRB of all time, GRB 221009A

A. J. Levan, G. P. Lamb, B. Schneider +57

We present JWST and Hubble Space Telescope (HST) observations of the afterglow of GRB 221009A, the brightest gamma-ray burst (GRB) ever observed. This includes the first mid-IR spe…
