KKR 18: A Late Arrival Galaxy?
R. Brent Tully, Valentina E. Karachentseva, Igor D. Karachentsev +8
KKR 18 is a dwarf irregular galaxy in the Local Void at a distance of 9.46 Mpc. It is gas rich and was experiencing vigorous star formation 20 - 100 Myr ago. Its metallicity is 4%…
Local Volume dwarf galaxy Cassiopea I. Gas metallicity, extinction and distance
S. A. Pustilnik, A. L. Tepliakova, A. S. Vinokurov
Cas I is a LV dIrr with a wide range of suggested distances. Tikhonov (2019), using the HST images and the TRGB method, places Cas I at D = 1.6+-0.1 Mpc. Besides, he estimates 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…
Nearby voids and their galaxies: recent progress and prospects
S. Pustilnik, Y. Perepelitsyna, A. Tepliakova +4
Voids occupy about 3/4 of the volume of the Universe and contain about 15% of its mass. Due to various observational selection effects, these structure elements and galaxies popula…
Local Volume dwarf KK242: radial velocity, SF region, and metallicity
S. A. Pustilnik, A. L. Tepliakova, Y. A. Perepelitsyna +5
KK242 is a LV dwarf of transition type residing in the void environment. Koda et al. present clear indications on its connection with Scd galaxy NGC6503. This implies the distance…
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) <~…
