Stellar feedback impact on the ionized gas kinematics in the dwarf galaxy Sextans B
Ivan S. Gerasimov, Oleg . V. Egorov, Alexei V. Moiseev +3
We investigated the ionised and atomic gas kinematics and excitation state in the central region of ongoing star formation of the nearby low-metallicity dwarf galaxy Sextans B. The…
Dwarfs in nearby voids: results of SALT spectroscopy
S. A. Pustilnik, A. Y. Kniazev, A. L. Tepliakova +2
In the framework of the ongoing project, aimed at the systematical studying galaxies in nearby voids, we conducted spectroscopy with the Southern African Large Telescope (SALT) of…
HI Studies of Extremely Metal Poor Dwarfs in Voids -- I
Sushma Kurapati, Simon A. Pustilnik, Evgeniya S. Egorova
We present and discuss the results of the Giant Metrewave Radio Telescope (GMRT) HI 21-cm line mapping for five isolated low-mass (M_bary ~(2--8)*10^7 Mo) eXtremely Metal Poor (XMP…
XMP gas-rich dwarfs in nearby voids: results of BTA spectroscopy
S. A. Pustilnik, E. S. Egorova, A. Y. Kniazev +4
We present the second part of results of the on-going project of searching for and studying eXtremely Metal-Poor (XMP, adopted as those with Z(gas) <~ Zo/30, or with 12+log(O/H) <~…
Search for gas accretion imprints in voids: II. The galaxy Ark 18 as a result of a dwarf-dwarf merger
E. S. Egorova, O. V. Egorov, A. V. Moiseev +3
The low-mass low-surface brightness (LSB) disc galaxy Arakelian 18 (Ark 18) resides in the Eridanus void and because of its isolation represents an ideal case to study the formatio…
XMP gas-rich dwarfs in Nearby Voids: results of SALT spectroscopy
S. A. Pustilnik, A. Y. Kniazev, Y. A. Perepelitsyna +1
In the framework of an ongoing project aimed at searching for and studying eXtremely Metal-Poor (XMP) very gas-rich blue dwarfs in nearby voids, we conducted spectroscopy with the…
XMP gas-rich dwarfs in Nearby Voids: candidate selection
S. A. Pustilnik, E. S. Egorova, Y. A. Perepelitsyna +1
We introduce a project aimed at systematically searching for eXtremely Metal-Poor (XMP) very gas-rich blue dwarfs in voids in the nearby Universe. Several such galaxies were first…
Very gas-rich extremely metal-poor blue void dwarfs
S. Pustilnik, Y. Perepelitsyna, A. Kniazev +2
Half-dozen of extreme representatives of void dwarf galaxy population were found in our study of evolutionary status of a hundred galaxies in the nearby Lynx-Cancer void. They are…
Search for gas accretion imprints in voids: I. Sample selection and results for NGC 428
E. S. Egorova, A. V. Moiseev, O. V. Egorov
We present the first results of a project aimed at searching for gas accretion events and interactions between late-type galaxies in the void environment. The project is based on l…
Study of galaxies in the Eridanus void. Sample and oxygen abundances
A. Y. Kniazev, E. S. Egorova, S. A. Pustilnik
We present a sample of 66 galaxies belonging to the equatorial part (Dec.= -7, +7) of the large so called Eridanus void (after Fairall 1998). The void galaxies are selected…
UGC 3672: An unusual merging triplet of gas-rich galaxies in the Lynx-Cancer void
Jayaram N. Chengalur, S. A. Pustilnik, E. S. Egorova
We present HI 21cm and optical observations of UGC 3672 which is located near the centre of the nearby Lynx-Cancer void. We find that UGC 3672 consists of an approximately linearly…
