Does the virial mass drive the intra-cluster light? The relationship between the ICL and M from VEGAS
Rossella Ragusa, Enrichetta Iodice, Marilena Spavone +7
In this Letter we revisit the relationship between the fraction of the intra-cluster light (ICL) and both the virial mass and the fraction of Early Type Galaxies in the host halo.…
Galaxy and Mass Assembly (GAMA): Extended Intra-Group Light in a group at from deep Hyper-Suprime Cam images
Cristina Martinez-Lombilla, Sarah Brough, Mireia Montes +7
We present a pilot study to assess the potential of Hyper Suprime-Cam Public Data Release 2 (HSC-PDR2) images for the analysis of extended faint structures within groups of galaxie…
Galaxy And Mass Assembly: Galaxy Morphology in the Green Valley, Prominent rings and looser Spiral Arms
Dominic Smith, Lutz Haberzettl, L. E. Porter +15
Galaxies broadly fall into two categories: star-forming (blue) galaxies and quiescent (red) galaxies. In between, one finds the less populated ``green valley". Some of these galaxi…
Deep Investigation of Neutral Gas Origins (DINGO): HI stacking experiments with early science data
Jonghwan Rhee, Martin Meyer, Attila Popping +19
We present early science results from Deep Investigation of Neutral Gas Origins (DINGO), an HI survey using the Australian Square Kilometre Array Pathfinder (ASKAP). Using ASKAP su…
The SAMI Galaxy Survey: Physical drivers of stellar-gas kinematic misalignments in the nearby Universe
A. Ristea, L. Cortese, A. Fraser-McKelvie +10
Misalignments between the rotation axis of stars and gas are an indication of external processes shaping galaxies throughout their evolution. Using observations of 3068 galaxies fr…
Red riding on hood: Exploring how galaxy colour depends on environment
Pankaj C. Bhambhani, Ivan. K. Baldry, Sarah Brough +4
Galaxy populations are known to exhibit a strong colour bimodality, corresponding to blue star-forming and red quiescent subpopulations. The relative abundance of the two populatio…
