Dwarf elliptical galaxies in Centaurus A group: stellar populations in AM 1339-445 and AM 1343-452
M. Rejkuba, G. S. Da Costa, H. Jerjen +2
We study the red giant populations of two dE galaxies, AM 1339-445 and AM 1343-452, with the aim of investigating the number and luminosity of any upper asymptotic giant branch (AG…
HI Detection in two Dwarf S0 Galaxies in Nearby Groups: ESO384-016 and NGC 59
Sylvie F. Beaulieu, Kenneth C. Freeman, Claude Carignan +2
An \hi survey of 10 dE/dS0 galaxies in the nearby Sculptor and Centaurus A groups was made using the Australia Telescope Compact Array (ATCA). The observed galaxies have accurate d…
The impact of accurate distances to dwarf elliptical galaxies on cosmology
Helmut Jerjen
The Surface Brightness Fluctuation method has been shown to be a powerful distance indicator for dwarf elliptical galaxies to very low surface brightness levels. It is applicable t…
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…
SAPAC: a SBF analysis pipeline for the astronomical community
Laura P. Dunn, Helmut Jerjen
Large volumes of CCD imaging data that will become available from wide-field cameras at telescopes such as the CFHT, SUBARU, VST, or VISTA in the near future are highly suitable fo…
New distances of unresolved dwarf elliptical galaxies in the vicinity of the Local Group
Rami Rekola, Helmut Jerjen, Chris Flynn
We present Surface Brightness Fluctuation distances of nine early-type dwarf galaxies and the S0 galaxy NGC 4150 in the Local Volume based on deep B- and R-band CCD images obtained…
