Low-Surface-Brightness Galaxies in the Sloan Digital Sky Survey. I. Search Method and Test Sample
Alexei Y. Kniazev, Eva K. Grebel, Simon A. Pustilnik +4
In this paper we present results of a pilot study to use imaging data from the Sloan Digital Sky Survey (SDSS) to search for low-surface-brightness (LSB) galaxies. For our pilot st…
Starburst in HS 0822+3542 induced by the very blue LSB dwarf SAO 0822+3545
S. A. Pustilnik, A. Y. Kniazev, A. G. Pramskij +2
(Abridged). One of the most metal-deficient blue compact galaxies (BCGs) HS 0822+3542 (Z=1/34 Zsun), is also one of the nearest such objects. A trigger mechanism for its current SF…
Search for and study of extremely metal-deficient galaxies
S. Pustilnik, A. Kniazev, A. Pramskij +1
We summarize the progress in identifying and observational study of extremely metal-deficient (XMD) gas-rich galaxies (BCGs, dIr and LSBDs). Due to volume limitations only followin…
Possibly interacting Vorontsov-Velyaminov galaxies. II. The 6m telescope spectroscopy of VV 080, 131, 499, 523 and 531
S. Pustilnik, A. Zasov, A. Kniazev +3
In continuation of the program formulated in Paper I we present results of long-slit spectroscopy with the Russian 6m telescope of five more objects from the Vorontsov-Velyaminov A…
