Burst properties of the most recurring transient magnetar SGR J1935+2154

Understand

We present timing and time-integrated spectral analysis of 127 bursts from SGR J1935+2154.

• These bursts were observed with the Gamma-ray Burst Monitor on the Fermi Gamma-ray Space Telescope and the Burst Alert Telescope on the Neil Gehrels Swift Observatory during the source's four active episodes from 2014 to 2016.
• This activation frequency makes SGR J1935+2154 the most burst prolific transient magnetar.
• We find the average duration of all the detected bursts to be much shorter than the typical, anticipated value.
