Does Very Short Gamma Ray Bursts originate from Primordial Black Holes? Review

Understand

We present the state of current research of Very Short Gamma Ray Bursts (VSGRBs) from seven GRB detectors.

• We found that VSGRBs form distinct class of GRBs, which in our opinion, in most cases can originate from the evaporating Primordial Black Holes (PBHs).
• Arguments supporting our opinion: 1.
• GRBs with time duration (T90) < 100 ms form distinct class: VSGRBs.
