The Environmental Influence on the Evolution of Local Galaxies
A. Bouchard, G. S. Da Costa, H. Jerjen
The results of an Halpha photometric survey of 30 dwarf galaxies of various morphologies in the Centaurus A and Sculptor groups are presented. Of these 30, emission was detected in…
ESO540-032: a Transition-Type Dwarf in the Sculptor Group
G. S. Da Costa, H. Jerjen, A. Bouchard
A color-magnitude diagram (CMD) based on HST/ACS data is presented for the Sculptor group dwarf galaxy ESO540-032. The CMD is dominated by an old red giant population but there is…
Interstellar medium disruption in the Centaurus A group
A. Bouchard, H. Jerjen, G. S. Da Costa +1
We present the results of a 21 cm neutral hydrogen (HI) line detection experiment in the direction of 18 low luminosity dwarf galaxies of the Centaurus A group, using the Australia…
Neutral Hydrogen Clouds near Early-Type Dwarf Galaxies of the Local Group
A. Bouchard, C. Carignan, L. Staveley-Smith
Parkes neutral hydrogen 21 cm line (HI) observations of the surroundings of 9 early-type Local Group dwarfs are presented. We detected numerous HI clouds in the general direction o…
Detection of neutral hydrogen in early-type dwarf galaxies of the Sculptor Group
Antoine Bouchard, Helmut Jerjen, Gary S. Da Costa +1
We present our results of deep 21 cm line (HI) observations of five early and mixed-type dwarf galaxies in the nearby Sculptor group using the ATNF 64m Parkes Radio Telescope. Four…
Clarification of the Nature of the Galaxy CFC97 Cen 05
Antoine Bouchard, Gary S. Da Costa, Helmut Jerjen
The galaxy CFC97 Cen 05 has in the past been considered an HI-rich dwarf galaxy in the nearby Centaurus A group. We have used Australia Telescope Compact Array observations to show…
