Revealing the Structure and Magnetization of GRB Jets with ALMA Polarization Observations
Tanmoy Laskar, Collin T. Christy, Noah Franz +9
We present a systematic study of the currently available ALMA millimeter polarimetric sample of gamma-ray burst (GRB) afterglows. Our sample comprises 24 observations (20 new) of 1…
Multiwavelength Modeling of the Luminous Fast Blue Optical Transient AT2024wpp
Conor M. B. Omand, Nikhil Sarin, Gavin P. Lamb +14
Luminous fast blue optical transients (LFBOTs) are a growing class of enigmatic energetic transients. They show fast rises and declines, high temperatures throughout their evolutio…
Prompt Periodicity in the GRB 211211A Precursor: Black-hole or magnetar engine?
Gavin P. Lamb, Thomas Baxter, Conor M. B. Omand +18
The merger origin long GRB 211211A was a class (re-)defining event. A precursor was identified with a s separation from the main burst, as well as a claimed candidate quas…
Probing the axial symmetry of gamma-ray burst jets using afterglow polarimetry
Thomas Baxter, Shiho Kobayashi
Polarisation measurements of gamma-ray burst afterglows provide a powerful tool for probing the structure of relativistic jets. In this study, we revisit polarisation signals obser…
The Radio to GeV Afterglow of GRB 221009A
Tanmoy Laskar, Kate D. Alexander, Raffaella Margutti +27
GRB 221009A () is one of the closest known long -ray bursts (GRBs). Its extreme brightness across all electromagnetic wavelengths provides an unprecedented opportunity…
The optical afterglow of the short gamma-ray burst associated with GW170817
J. D. Lyman, G. P. Lamb, A. J. Levan +33
The binary neutron star merger GW170817 was the first multi-messenger event observed in both gravitational and electromagnetic waves. The electromagnetic signal began approximately…
The unpolarized macronova associated with the gravitational wave event GW170817
S. Covino, K. Wiersema, Y. Z. Fan +37
The merger of two dense stellar remnants including at least one neutron star (NS) is predicted to produce gravitational waves (GWs) and short duration gamma ray bursts (GRBs). In t…
A Reverse Shock and Unusual Radio Properties in GRB 160625B
K. D. Alexander, T. Laskar, E. Berger +9
We present multi-wavelength observations and modeling of the exceptionally bright long -ray burst GRB 160625B. The optical and X-ray data are well-fit by synchrotron emission fr…
Circular polarization in the optical afterglow of GRB 121024A
K. Wiersema, S. Covino, K. Toma +37
Gamma-ray bursts (GRBs) are most probably powered by collimated relativistic outflows (jets) from accreting black holes at cosmological distances. Bright afterglows are produced wh…
GRB 130427A: a Nearby Ordinary Monster
A. Maselli, A. Melandri, L. Nava +63
Long-duration Gamma-Ray Bursts (GRBs) are an extremely rare outcome of the collapse of massive stars, and are typically found in the distant Universe. Because of its intrinsic lumi…
