An Afterglow Study of the "New Year's Burst" GRB 220101A

Agniva Roychowdhury, Tuomas Kangas, Andrew Fruchter +12

We present a detailed broadband afterglow study of GRB 220101A ( s) combining multi-wavelength data from soft X-rays until 6 GHz. The afterglow light cu…

The Redshift of GRB 190829A/ SN 2019oyw: A Case Study of GRB-SN Evolution

Kornpob Bhirombhakdi, Andrew S. Fruchter, Andrew J. Levan +7

The nearby long gamma-ray burst (GRB) 190829A was observed using the HST/WFC3/IR grisms about four weeks to 500 days after the burst. We find the spectral features of its associate…

A Hubble Space Telescope Search for r-Process Nucleosynthesis in Gamma-ray Burst Supernovae

J. C. Rastinejad, W. Fong, A. J. Levan +23

The existence of a secondary (in addition to compact object mergers) source of heavy element (-process) nucleosynthesis, the core-collapse of rapidly-rotating and highly-magneti…

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…

An extremely energetic supernova from a very massive star in a dense medium

Matt Nicholl, Peter K. Blanchard, Edo Berger +14

The interaction of a supernova with a circumstellar medium (CSM) can dramatically increase the emitted luminosity by converting kinetic energy to thermal energy. In 'superluminous'…

Observational constraints on the optical and near-infrared emission from the neutron star-black hole binary merger S190814bv

K. Ackley, L. Amati, C. Barbieri +151

On 2019 August 14, the LIGO and Virgo interferometers detected a high-significance event labelled S190814bv. Preliminary analysis of the GW data suggests that the event was likely…
