Estimation of the Star Formation Rate (sfr) Through Data Analysis of Swift's - GRBs from 2008 TO 2017
Abstract
This work presents a research about the Star Formation Rate (SFR), using data analyzing of a sample from 2008 to 2017 of Gamma Ray Bursts (GRBs) submitted by Swift Gamma-Ray Burst Mission, This work is based on the empirical model proposed by Yuksel, Kistler & Beacom. (2008), basically the SFR is measured using long-GRBs considering a core-collapsed model of high rotating massive stars with low metallicity. Studying ɛ(z) which accounts the production rate of long-GRBs with additional evolutive effects, parameterizing of the form ɛ(z)=ɛ_{ 0 }(1+z)^{δ}, where ɛ_{0} is a unknown constant which include the total conversion of the SFR rate to GRB rate in a luminosity range given, finally we discuss the possible effect in the chemical evolution of galaxies at high redshift.
