Separating C-stars from Dust in the Central Region of the Seyfert 2 Galaxy NGC 1241
Horacio Dottori, Ruben J. Diaz, Gustavo Carranza +2
The Sy 2 galaxy NGC 1241 presents a 1.5 kpc large circumnuclear ring of star formation (CNR) embracing a small bar plus leading arms. Those structures are P alpha emitters, but bar…
Open clusters or their remnants: B and V photometry of NGC 1901 and NGC 1252
D. B. Pavani, E. Bica, C. M. Dutra +4
Photometry in the B and V bands is presented for the southern stellar groups NGC 1901 and NGC 1252. NGC 1901 is often described as an open cluster while NGC 1252 consists of a conc…
Extreme Galactic-Winds and Starburst in IR Mergers and IR QSOs
S. Lipari, D. Sanders, R. Terlevich +8
We report -as a part of a long-term study of mergers and IR QSOs- detailed spectroscopic evidences for outflow (OF) and/or Wolf Rayet features in: (i) low velocity OF in the ongoin…
Luminous Infrared Galaxies. III. Multiple Merger, Extended Massive Star Formation, Galactic-Wind and Nuclear-Inflow in NGC 3256
S. Lipari, R. Diaz, Y. Taniguchi +3
We find in a detailed morphological study (at 15 pc resolution) that the extended massive star formation process, shows: (i) extended triple asymmetrical spiral arms structure (r =…
