HI and star formation in the most metal-deficient galaxies
Ekta, Jayaram N. Chengalur, S. A. Pustilnik
We present Giant Metrewave Radio Telescope (GMRT) observations for three (viz., DDO 68, SDSS J2104-0035 and UGC 772) of the six most metal-deficient actively star-forming galaxies…
Discovery of a massive variable star with Z=Zo/36 in the galaxy DDO 68
S. A. Pustilnik, A. L. Tepliakova, A. Y. Kniazev +1
The Local Volume dwarf galaxy DDO 68, from the spectroscopy of its two brightest HII regions (Knots 1 and 2) was designated as the second most metal-poor star-forming galaxy [12+lo…
Andromeda IV: a new Local Volume very metal-poor galaxy
S. A. Pustilnik, A. L. Tepliakova, A. Y. Kniazev +2
And IV is a low-surface brightness (LSB) dwarf galaxy at the distance of 6.1 Mpc, projecting close to M 31. In this paper the results of spectroscopy of And IV the two brightest HI…
"Dark galaxies" and local very metal-poor gas-rich galaxies: possible interrelations
Simon A. Pustilnik
There are only a few ``dark galaxy'' candidates discovered to date in the local Universe. One of the most prominent of them is the SW component of a merging system HI 1225+01. On t…
Spectroscopy of two PN candidates in IC10
A. Y. Kniazev, S. A. Pustilnik, D. B. Zucker
We present the results of the first spectroscopic observations of two planetary nebula (PN) candidates in the Local Group dwarf irregular galaxy IC10. Using several spectral classi…
The metallicity extremes of the Sagittarius dSph using SALT spectroscopy of PNe
A. Kniazev, A. Zijlstra, E. Grebel +10
In this work we present the first spectroscopic results obtained with the Southern African Large Telescope (SALT) telescope during its perfomance-verification phase. We find that t…
