A new red giant-based distance modulus of 13.3 Mpc to the Antennae galaxies and its consequences
Ivo Saviane, Yazan Momany, Gary S. Da Costa +2
The Antennae galaxies are the closest example of an ongoing major galaxy merger, and thereby represent a unique laboratory for furthering the understanding of the formation of exot…
Abundances on the Main Sequence of Omega Centauri
Laura M. Stanford, G. S. Da Costa, John E. Norris
Abundance ratios of carbon, nitrogen and strontium relative to iron, calculated using spectrum synthesis techniques, are given for a sample of main sequence and turnoff stars that…
A Sr-Rich Star on the Main Sequence of Omega Centauri
Laura M. Stanford, G. S. Da Costa, John E. Norris +1
Abundance ratios relative to iron for carbon, nitrogen, strontium and barium are presented for a metal-rich main sequence star ([Fe/H]=--0.74) in the globular cluster omega Centaur…
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…
The Nature of the Density Clump in the Fornax Dwarf Spheroidal Galaxy
Edward W. Olszewski, Mario Mateo, Jason Harris +3
We have imaged the recently discovered stellar overdensity located approximately one core radius from the center of the Fornax dwarf spheroidal galaxy using the Magellan Clay 6.5m…
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…
