The spatial distribution of GRBs
The spatial distribution of GRBs
Blog Article
We analysed the different aspects of the spatial distribution of 542 Gamma-Ray Bursts with precisely determined positions and spectroscopic redshifts.The data were divided according to the origin of the redshift (afterglow or host galaxy).The yearly nightstick twm-850xl rate of afterglow and host-based redshift observations are different, with only a few host observations in the recent years.
Since the launch of the Swift, the rate of afterglow observations fall exponentially by 50 % in 15 years, potentially affecting all planned GRB missions.We also analysed the rest-frame T90 values from the Swift BAT and FERMI GBM catalogues with the redshift data.The host- and afterglow-based points are separated in the redshift range due to observational effects, but no direct distinction could be made between the rest-frame T90 values.
The correlation analysis between the GRB redshift and sky position giantmouse jagt shows that the GRB distribution could be factorised into a separate sky and radial components.
