On the neutral gas distribution and kinematics in the dwarf irregular galaxy IC 1613
Sergiy Silich, Tatyana Lozinskaya, Alexei Moiseev +4
We study the neutral hydrogen distribution and kinematics in the Local Group dwarf irregular galaxy IC 1613 and compare them with the ionized gas distribution and stellar content o…
Is HCG31 undergoing a merger or a fly-by interaction?
M. G. Richer, L. Georgiev, M. Rosado +3
We present Fabry-Perot and multi-object spectroscopy of the galaxies in Hickson compact group 31 (HCG31). Based upon our H data cubes, galaxies A and C are a single entity, show…
Unveiling the Behavior of the Ionized Gas in Irregular Galaxies
Margarita Valdez-Gutierrez, Margarita Rosado, ;
We present the results of a detailed kinematical and dynamical analysis performed in two highly interesting gas-rich Irregular galaxies (Irrs): IC 1613 and NGC 4449. The analysis h…
A Fabry-Perot Study of the Scd I galaxy NGC 5457
Ivanio Puerari, Margarita Valdez-Gutierrez, Margarita Rosado
We have analyzed Halpha Fabry-Perot interferograms of NGC 5457 (M101) in order to calculate the rotation curve. We have also isolated a sample of 263 HII regions and we determined…
The Red Stellar Contents of Three Selected Fields of The Local Group Dwarf Irregular Galaxy IC1613
J. Borissova, L. Georgiev, R. Kurtev +4
We present a moderately-deep JK photometry for three selected areas of the dwarf irregular galaxy IC1613. The color-magnitude diagrams contain a mixture of red supergiants, asympto…
