Late time multi wavelength observations of Swift J1644+5734: A luminous optical/IR bump and quiescent X-ray emission
A. J. Levan, N. R. Tanvir, G. C. Brown +10
We present late-time multi-wavelength observations of Swift J1644+57, suggested to be a relativistic tidal disruption flare (TDF). Our observations extend to >4 years from discover…
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…
A new population of ultra-long duration gamma-ray bursts
A. J. Levan, N. R. Tanvir, R. L. C. Starling +38
We present comprehensive multiwavelength observations of three gamma-ray bursts (GRBs) with durations of several thousand seconds. We demonstrate that these events are extragalacti…
