Characterization of a peculiar Einstein Probe transient EP240408a: an exotic gamma-ray burst or an abnormal jetted tidal disruption event?
B. O'Connor, D. Pasham, I. Andreoni +30
We present the results of our multi-wavelength (X-ray to radio) follow-up campaign of the Einstein Probe transient EP240408a. The initial 10 s trigger displayed bright soft X-ray (…
Searching for the Signature of Fast Radio Burst by Swift/XRT X-ray Afterglow Light Curve
Hsien-chieh Shen, Takanori Sakamoto, Motoko Serino +1
A new type of cosmological transient, dubbed fast radio bursts (FRBs), was recently discovered. The source of FRBs is still unknown. One possible scenario of an FRB is the collapse…
The outflow structure of GW170817 from late time broadband observations
E. Troja, L. Piro, G. Ryan +6
We present our broadband study of GW170817 from radio to hard X-rays, including NuSTAR and Chandra observations up to 165 days after the merger, and a multi-messenger analysis incl…
An achromatic break in the afterglow of the short GRB 140903A: evidence for a narrow jet
E. Troja, T. Sakamoto, S. B. Cenko +17
We report the results of our observing campaign on GRB140903A, a nearby (z=0.351) short duration (T90~0.3 s) gamma-ray burst discovered by Swift. We monitored the X-ray afterglow w…
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…
