High S/N composite spectrum of GRB afterglows
Listed in IVOA Registry (Virtual Observatory)
We present a composite spectrum of 60 long duration gamma-ray burst (GRB) afterglows with redshifts in the range 0.35<z<6.7 observed with low-resolution optical spectra.
Description
The composite spectrum covers the wavelength range 700-6600{AA} in the rest frame and has a mean signal-to-noise ratio of 150 per 1{AA} pixel and reaches a maximum of ~300 in the range 2500-3500{AA}. Equivalent widths are measured from metal absorption lines from the Ly{alpha} line to ~5200{AA}, and associated metal and hydrogen lines are identified between the Lyman break and Ly{alpha} line.
The average transmission within the Lyman forest is consistent with that found along quasar lines of sight.
