چکیده

As starburst galaxies show a star formation rate up to several hundred times larger than the one in a typical galaxy, the expected supernova rate is higher than average. This in turn implies a high rate of long gamma ray bursts (GRBs), which are extreme supernova events. We present a catalog of 127 local starburst galaxies with redshifts of z < 0.03. Using this catalog we investigate the possibility of detecting neutrinos from Gamma Ray Bursts from nearby starburst galaxies. We show that the rate of long GRBs is correlated to the supernova rate which in turn is correlated to the far infrared output. For the entire catalog, 0.03 GRB per year are expected to occur. The true number can even be higher since only the brightest sources were included in the catalog.

The 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...

The Ero Host Galaxy of Grb 020127: Implications for the Metallicity of Grb Progenitors

We present optical and near-IR observations of the host galaxy of GRB 020127, for which we measure R Ks 1⁄4 6:2mag. This is only the second GRB host to date classified as an ERO. The spectral energy distribution (SED) is typical of a dusty starburst galaxy, with a redshift z 1:9, a luminosity L 5L , and an inferred stellar mass of M 10 10 M , two orders of magnitude moremassive than typical GRB...

Host Galaxy of GRB 020127 : Implications for the Metallicity of GRB Progenitors

We present optical and near-IR observations of the host galaxy of GRB020127, for which we measure R−Ks = 6.2 mag. This is only the second GRB host to date, which is classified as an ERO. The spectral energy distribution is typical of a dusty starburst galaxy, with a redshift, z ≈ 1.9, a luminosity, L ≈ 5 L, and an inferred stellar mass of M∗ ∼ 10 11 − 10 M⊙, two orders of magnitude more massive...

The host galaxy of GRB 011121 : Morphology and Spectral Energy Distribution ⋆ , ⋆ ⋆

We present a detailed study of the host galaxy of GRB 011121 (at z = 0.36) based on high-resolution imaging in 5 broad-band, optical and near-infrared filters with HST and VLT/ISAAC. The surface brightness profile of this galaxy is best fitted by a Sersic law with index n ∼ 2 – 2.5 and a rather large effective radius (∼ 7.5 kpc). Both the morphological analysis and the F450W F702W colour image ...
