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 Broad-band Counterpart of the Short GRB 200522A at : A Luminous Kilonova or a Collimated Outflow with a Reverse Shock?

W. Fong, T. Laskar, J. Rastinejad +20

We present the discovery of the radio afterglow and near-infrared (NIR) counterpart of the Swift short GRB 200522A, located at a small projected offset of kpc from the…

The Case for a High-Redshift Origin of GRB100205A

A. A. Chrimes, A. J. Levan, E. R. Stanway +15

The number of long gamma-ray bursts (GRBs) known to have occurred in the distant Universe (z greater than 5) is small (approx 15), however these events provide a powerful way of pr…

The fraction of ionizing radiation from massive stars that escapes to the intergalactic medium

N. R. Tanvir, J. P. U. Fynbo, A. de Ugarte Postigo +38

The part played by stars in the ionization of the intergalactic medium remains an open question. A key issue is the proportion of the stellar ionizing radiation that escapes the ga…
