photometry of GRB 980703 and GRB 990123 host galaxies
We present a photometry of GRB 980703 and GRB 990123 host galaxies which was performed after about 20 days and a half year after gamma-bursts occur, respectively. This fact allows us to consider that we observed host galaxies light only. The contributions of the optical transiets (OT) were negligible in both cases. We derived the broad band BV RcIc spectra of the host galaxies and compared them...

We present a photometry of GRB 980703 and GRB 990123 host galaxies which was performed about 20 days and a half year after gamma-ray bursts occured, respectively. The contributions of the optical transiets (OT) were negligible in both cases. We derived broad band BV RcIc spectra of the host galaxies and compared them to continuum spectra of different Hubble-type galaxies and averaged spectra of...
متن کاملThe submm properties of GRB host galaxies
Long duration gamma-ray bursts (GRBs) accompany the deaths of some massive stars and hence, since massive stars are short lived, are a tracer of star formation activity. Given that GRBs are bright enough to be seen to very high redshifts, and detected even in dusty environments, they should therefore provide a powerful probe of the global star formation history of the universe. The potential of...
متن کاملNumerical counterparts of GRB host galaxies
We explore galaxy properties in general and properties of host galaxies of gammaray bursts (GRBs) in particular, using N-body/Eulerian hydrodynamic simulations and the stellar population synthesis model, Starburst99, to infer observable properties. We identify simulated galaxies that have optical star formation rate (SFR) and SFRto-luminosity ratio similar to those observed in a well-defined sa...
متن کاملThe Multiband Photometry of the GRB Host Galaxies
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 compariso...
