The Multiband Photometry of the GRB Host Galaxies

Abstract

We present photometric multiband spectral energy distributions for the GRB host galaxies: GRB 971214, GRB 970508, GRB 980613, GRB 980703 and GRB 990123 obtained with the 6-m telescope of SAO RAS. Using SEDs for the starburst galaxies, we made estimates of K-correction values and estimated the absolute magnitudes of the GRB host galaxies within the range of cosmological parameters. The comparison of the broad band spectra of these galaxies with the spectra of galaxies of different morphological types (Connolly et al, 1995, AJ, 110, 1071) shows that the GRB host galaxies are best fitted by the spectral properties of S2-S5 averaged SEDs of starburst galaxies.
