More than just halo mass: Modelling how the red galaxy fraction depends on multiscale density in a HOD framework
Stefanie Phleps, David J. Wilman, Stefano Zibetti +1
The fraction of galaxies with red colours depends sensitively on environment, and on the way in which environment is measured. To distinguish competing theories for the quenching o…
The Herschel Virgo Cluster Survey XIV: transition-type dwarf galaxies in the Virgo cluster
Ilse De Looze, Maarten Baes, Alessandro Boselli +19
We use dust scaling relations to investigate the hypothesis that Virgo cluster transition-type dwarfs are infalling star-forming field galaxies, which is argued based on their opti…
