A spectrophotometric catalogue of HII galaxies
Cristina C. Popescu, Ulrich Hopp
We present a spectrophotometric catalogue of 90 emission-line galaxies (ELGs) discovered during an objective - prism survey that aimed to search for dwarf galaxies within the voids…
A Near-Infrared Stellar Census of the Blue Compact Dwarf Galaxy VII~Zw~403
Regina E. Schulte-Ladbeck, Ulrich Hopp, Laura Greggio +1
We present near-infrared single-star photometry for the low-metallicity Blue Compact Dwarf galaxy VII~Zw~403. We achieve limiting magnitudes of F110W~~25.5 and F160W~$\app…
On the star-formation properties of emission-line galaxies in and around voids
Cristina C. Popescu, Ulrich Hopp, Michael R. Rosa
We present a study of the star formation properties of a sample of emission line galaxies (ELGs) with respect to their environment. This study is part of a bigger project that aime…
A Stellar Population Gradient in VII Zw 403 - Implications for the Formation of Blue Compact Dwarf Galaxies
Regina E. Schulte-Ladbeck, Ulrich Hopp, Mary M. Crone +1
We present evidence for the existence of an old stellar halo in the Blue Compact Dwarf galaxy VII Zw 403. VII Zw 403 is the first Blue Compact Dwarf galaxy for which a clear spatia…
