dc.description.abstract |
We present a detailed analysis of short GRB 201221D lying at redshift z = 1.045. We analyse the high-energy data of the burst
and compare it with the sample of short gamma-ray bursts (SGRBs). The prompt emission characteristics are typical of those
seen in the case of other SGRBs except for the peak energy (Ep), which lies at the softer end (generally observed in the case of
long bursts). We estimate the host galaxy properties by utilizing the Python-based software Prospector to fit the spectral
energy distribution of the host. The burst lies at a high redshift relative to the SGRB sample with a median redshift of z = 0.47.
We compare the burst characteristics with other SGRBs with known redshifts along with GRB 200826A (SGRB originated from
a collapsar). A careful examination of the characteristics of SGRBs at different redshifts reveals that some of the SGRBs lying
at high redshifts have properties similar to long GRBs indicating they might have originated from collapsars. Further study of
these GRBs can help to explore the broad picture of progenitor systems of SGRBs. |
