Global trends in morphology from massive to dwarf galaxies
Ilin Lazar, Sugata Kaviraj, Christopher J. Conselice +7
The morphological properties of dwarf galaxies (Mstar < 10^9.5 MSun) remain largely unexplored, particularly outside the local neighbourhood. We explore how morphology changes acro…
Extended Structure in E+A Galaxies Via Image Stacking
Kieran Broadbelt, Kevin Pimbblet, Daniel Farrow +1
Small-scale interactions such as minor mergers, flybys and harassment are considered common driving mechanisms that can both initiate and quench star-forming processes within post-…
Zippers and Twisters: Planes of Satellite Galaxies Emerge from Whirling and Shocking Gas Streams in the Cosmic Web
Janvi P. Madhani, Charlotte Welker, Sneha Nair +7
We investigate dwarf satellite systems around Milky Way analogs in the NewHorizon simulation. Using simple estimators limiting over-detection, we identify planes of satellites comp…
Isophote shape analysis and the unfortunate subtlety of dwarf galaxy structure
A. E. Watkins, I. Lazar, T. Sedgwick +5
Dwarf galaxies (), being sensitive to key evolutionary drivers like baryonic feedback and tidal perturbation, are crucial for understanding galax…
AGN in massive galaxies identified via optical broadband variability: lessons from VST-COSMOS for future LSST science
B. Bichang'a, D. De Cicco, S. Kaviraj +4
We study the properties of 56 massive (M > 10 M) galaxies at that host AGN, detected via their broadband optical variability in the VST-COSMOS…
Downsizing does not extend to dwarf galaxies: identifying the stellar mass regimes shaped by supernova and AGN feedback
Ilin Lazar, Sugata Kaviraj, Garreth Martin +10
We explore how the fraction of red (quenched) galaxies varies in the dwarf galaxy regime (10^7 MSun < Mstar < 10^9.5 MSun), using a mass-complete sample of ~5900 dwarfs at z<0.15,…
