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 Kinematics and Dynamics of Ionized Gas in the Nearby Irregular Galaxy NGC 4449
Margarita Valdez-Gutierrez, Margarita Rosado, Ivanio Puerari +3
A detailed kinematic analysis of ionized gas in the nearby irregular galaxy NGC 4449 is presented. Observations are conducted in the spectral lines of Halpha and [SII]. Our scannin…
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…
