A too-many dwarf galaxy satellites problem in the M83 group
Oliver Müller, Marcel S. Pawlowski, Yves Revaz +4
Dwarf galaxies in groups of galaxies provide excellent test cases for models of structure formation. This led to a so-called small-scale crisis, including the famous missing satell…
The HI in Ring Galaxies Survey (HI-RINGS) -- Effects of the bar on the HI gas in ring galaxies
Chandrashekar Murugeshan, Robert Dzudzar, Ryan Bagge +6
We present a new high-resolution neutral atomic hydrogen (HI) survey of ring galaxies using the Australia Telescope Compact Array (ATCA). We target a sample of 24 ring galaxies fro…
xCOLDGASS and xGASS: Radial metallicity gradients and global properties on the star-forming main sequence
K. A. Lutz, A. Saintonge, B. Catinella +7
Context. The xGASS and xCOLD GASS surveys have measured the atomic (HI) and molecular gas (H2) content of a large and representative sample of nearby galaxies (redshift range of 0.…
Radio data archives round table
K. A. Lutz, J. Dempsey, Y. G. Grange +3
With SKA precursor and pathfinder operations in full swing, radio and (sub-)mm astronomy is entering the era of super big data. The big questions is how to make (sub-)mm and radio…
Radio Astronomy visibility data discovery and access using IVOA standards
Mireille Louys, Katharina Lutz, Yelena Stein +2
Enhancing interoperable data access to radio data has become a science priority within the International Virtual Observatory Alliance (IVOA). This lead to the foundation of the IVO…
The properties of dwarf spheroidal galaxies in the Cen A group: Stellar populations, internal dynamics, and a heart-shaped Halpha ring
Oliver Müller, Katja Fahrion, Marina Rejkuba +7
Dwarf spheroidal galaxies (dSphs) have been extensively investigated in the Local Group, but their low luminosity and surface brightness make similar work in more distant galaxy gr…
