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.…
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…
The H IX galaxy survey III: The gas-phase metallicity in HI eXtreme galaxies
K. A. Lutz, V. Kilborn, B. Catinella +3
This paper presents the analysis of optical integral field spectra for the HI eXtreme (HIX) galaxy sample. HIX galaxies host at least 2.5 times more atomic gas (HI) than expected f…
Angular momentum regulates HI gas content and HI central hole size in the discs of spirals
Chandrashekar Murugeshan, Virginia Kilborn, Danail Obreschkow +4
The neutral atomic hydrogen (HI) content of spiral galaxies has been observed to vary with environment, with more HI-deficient spirals residing in high density environments. This c…
