Circumnuclear Regions of Star Formation in Early Type Galaxies
Angeles I. Diaz, Elena Terlevich, Guillermo F. Hagele +1
Circumnuclear star forming regions, also called hotspots, are often found in the inner regions of some spiral galaxies where intense processes of star formation are taking place. I…
Structural parameters of nearby emission-line galaxies
Miguel Sanchez-Portal, Angeles I Diaz, Elena Terlevich +1
We present the results of an investigation on the main structural properties derived from VRI and Halpha surface photometry of galaxies hosting nuclear emission-line regions (inclu…
12CO mapping of the low-metallicity BCD galaxy Mrk86
A. Gil de Paz, S. A. Silich, B. F. Madore +3
We have mapped the 12CO J=1-0 and J=2-1 line emission in Mrk86, one of the most metal-deficient Blue Compact Dwarf galaxies so far detected in 12CO. The 12CO emission is distribute…
Search for optical microvariability in a large sample of Seyfert I galaxies
P. O. Petrucci, A. Chelli, G. Henri +3
We present results of an optical (I band) monitoring of a sample of 22 Seyfert I galaxies. We aimed to detect microvariability with time resolution from ~ 6 minutes down to 30 seco…
