Star-Forming Regions in Dwarf Galaxies of the Local Volume
S. S. Kaisin, I. D Karachentsev
We present the H-alpha flux measurements for 44 nearby dwarf galaxies, derived from the observations at the 6-m BTA telescope. H-alpha fluxes were used to determine the rate of int…
H-alpha survey of low-mass satellites of the neighbouring galaxies M31 and M81
S. S. Kaisin, I. D. Karachentsev
Images have been obtained at the 6-m telescope at the Special Astrophysical Observatory (SAO) of the Russian Academy of Sciences in the H-alpha line and in the continuum for 20 dwa…
Atomic hydrogen, star formation and feedback in the lowest mass Blue Compact Dwarf galaxies
Sambit Roychowdhury, Jayaram N. Chengalur, Kristin Chiboucas +3
We present the results from a search for HI emission from a sample of newly discovered dwarf galaxies in the M81 group. HI is detected in three galaxies, all of which are classifie…
H-alpha survey of nearby dwarf galaxies
S. S. Kaisin, I. D. Karachentsev, S. Ravindranath
We present the H-alpha imaging data and flux measurements for 30 dwarf galaxies in the Local volume. The H-alpha fluxes are used to derive the galaxy star formation rate, SFR. The…
Emission sparks around M 81 and in some dSph galaxies
Igor Karachentsev, Elena Kaisina, Serafim Kaisin +1
We use H-alpha images of three clumps of young stars situated between M81 and NGC3077 to estimate their star formation rate. Radial velocities of the clumps measured by us, as well…
Small Bites: Star formation recipes in extreme dwarfs
Sambit Roychowdhury, Jayaram N. Chengalur, Serafim S. Kaisin +2
We study the relationship between the gas column density (Sigma_HI) and the star formation rate surface density (Sigma_SFR) for a sample of extremely small (M_B ~ -13, Delta V_50 ~…
