Red-shift Distribution of Gamma-ray Bursts and Their Progenitors
Gamma ray bursts have been divided into two classes, long-soft gamma ray burst and short-hard gamma ray burst according to the bimodal distribution in duration time. Due to the harder spectrum and the lack of afterglows of short-hard bursts in optical and radio observations, different progenitors for short-hard bursts and long-soft bursts have been suggested. Based on the X-ray afterglow observ...
متن کاملDifferent progenitors of short hard gamma–ray bursts
We consider the spatial offsets of short hard gamma–ray bursts (SHBs) from their host galaxies. We show that all SHBs with extended–duration soft emission components lie very close to their hosts. We suggest that NS-BH binary mergers offer a natural explanation for the properties of this extended–duration/low offset group. SHBs with large offsets have no observed extended emission components an...
متن کاملFeeding Compact Objects: Accretion on All Scales
By collecting 17 short gamma-ray bursts with necessary data, we find a correlation of Lp ∝ E .7 p ,i , which is very consistent with that derived from a greatly expanded sample of 148 Swift long gamma-ray bursts. It is argued that the radiation mechanism of both long and short gamma-ray bursts should be similar, i.e., of quasi-thermal origin caused by the photosphere and the dissipation occurri...
متن کاملThe Short Burst Revolution
Gamma-ray bursts (GRBs) are among the most energetic explosions in the Universe. They are generally divided into two main classes: long duration-soft spectrum bursts, which last ~2 to hundreds of seconds; and, short duration-hard GRBs, which last less than 2 seconds and are spectrally “harder” than the first class. Over the past few years, the long-soft GRBs have been shown to be associated wit...
متن کاملObservations of short gamma-ray bursts.
We review recent observations of short-hard gamma-ray bursts and their afterglows. The launch and successful ongoing operations of the Swift satellite, along with several localizations from the High-Energy Transient Explorer mission, have provoked a revolution in short-burst studies: first, by quickly providing high-quality positions to observers; and second, via rapid and sustained observation...
