Late-type dwarf irregular galaxies in the Virgo cluster.I. H-alpha and red continuum data
Ana Heller, Elchanan Almoznino, Noah Brosch
We present H-alpha and red continuum observations for a sample of late-type low surface brightness (LSB) dwarf irregular galaxies(DIGs), consisting of all the m_B<17.2 ImIV and V g…
Testing Environmental Influences on Star Formation with a Sample of LSB Dwarf Galaxies in the Virgo Cluster
A. Heller, E. Almoznino, N. Brosch
We analyze the star formation activity of an homogeneous LSB dwarf galaxy sample in the Virgo cluster, as a function of the radial velocity relative to the cluster mean velocity an…
Morphological aspects of star formation in dwarf galaxies
Noah Brosch, Ana Heller, Elchanan Almoznino
We studied the morphology of star formation in dwarf irregular galaxies and found that, in general, this takes place on one side of a galaxy and far from the center. This is mainly…
Morphology of Star Formation Regions in Irregular Galaxies
Noah Brosch, Ana Heller, Elchanan Almoznino
The location of HII regions, which indicates the locus of present star formation in galaxies, is analyzed for a large collection of 110 irregular galaxies (Irr) imaged in H and…
