Star-forming galaxies with hot dust emission in the Sloan Digital Sky Survey discovered by the Wide-field Infrared Survey Explorer (WISE)
Y. I. Izotov, N. G. Guseva, K. J. Fricke +1
We present the results of a search for Sloan Digital Sky Survey (SDSS) emission-line galaxies with very red 3.4mum - 4.6mum (W1-W2) colours in the Wide-field Infrared Survey Explor…
A nearby GRB host galaxy: VLT/X-shooter observations of HG 031203
N. G. Guseva, Y. I. Izotov, K. J. Fricke +1
(abridged) Long-duration gamma-ray bursts (LGRBs) occur in galaxies of generally low metallicity. We aim at a spectroscopic analysis of HG 031203, the host galaxy of a LRGB burst,…
VLT spectroscopy of low-metallicity emission-line galaxies: abundance patterns and abundance discrepancies
N. G. Guseva, Y. I. Izotov, G. Stasinska +3
(abridged) We present deep spectroscopy of a large sample of low-metallicity emission-line galaxies. The main goal of this study is to derive element abundances in these low-metall…
VLT/X-shooter observations of the low-metallicity blue compact dwarf galaxy PHL 293B including a luminous blue variable star
Y. I. Izotov, N. G. Guseva, K. J. Fricke +1
(abridged) We present VLT/X-shooter spectroscopic observations in the wavelength range 3000-23000A of the extremely metal-deficient blue compact dwarf (BCD) galaxy PHL 293B contain…
Near-infrared spectroscopy of five Blue Compact Dwarf galaxies: II Zw 40, Mrk 71, Mrk 930, Mrk 996 and SBS 0335-052E
Y. I. Izotov, T. X. Thuan
We present near-infrared (NIR) spectroscopic observations of five blue compact dwarf (BCD) galaxies, II Zw 40, Mrk 71, Mrk 930, Mrk 996 and SBS 0335-052E. The NIR spectra which cov…
