The relationship between morphology, density, and location in the cosmic web from massive to dwarf galaxies
Ilin Lazar, Sugata Kaviraj, Aaron E. Watkins +5
We study how morphology relates to environment from massive to dwarf galaxies using, for the first time, a mass-complete sample of ~13,000 galaxies, in the stellar-mass and redshif…
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…
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…
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,…
The Star Formation Rates of Elliptical Galaxies from Core-Collapse Supernovae
Thomas M. Sedgwick, Ivan K. Baldry, Philip A. James +2
The level of star formation in elliptical galaxies is poorly constrained, due to difficulties in quantifying the contamination of flux-based estimates of star formation from unrela…
The origin of low-surface-brightness galaxies in the dwarf regime
R. A. Jackson, G. Martin, S. Kaviraj +15
Low-surface-brightness galaxies (LSBGs) -- defined as systems that are fainter than the surface-brightness limits of past wide-area surveys -- form the overwhelming majority of gal…
The effects of peculiar velocities in SN Ia environments on the local measurement
Thomas M. Sedgwick, Chris A. Collins, Ivan K. Baldry +1
The discrepancy between estimates of the Hubble Constant () measured from local () scales and from scales of the sound horizon is a crucial problem in modern c…
The galaxy stellar mass function from CCSNe with improved photo-z techniques
Thomas M. Sedgwick, Ivan K. Baldry, Philip A. James +1
In Sedgwick et al. (2019) we introduced and utilised a method to combat surface brightness and mass biases in galaxy sample selection, using core-collapse supernovae (CCSNe) as poi…
The Galaxy Stellar Mass Function and Low Surface Brightness Galaxies from Core-Collapse Supernovae
Thomas M. Sedgwick, Ivan K. Baldry, Philip A. James +1
We introduce a method for producing a galaxy sample unbiased by surface brightness and stellar mass, by selecting star-forming galaxies via the positions of core-collapse supernova…
