The dwarf stellar mass function in different environments and the lack of a generic missing dwarfs problem in ΛCDM

Ilin Lazar, Sugata Kaviraj, Garreth Martin +9

We combine deep photometric data in the COSMOS and XMM-LSS fields with high-resolution cosmological hydrodynamical simulations to explore two key questions: (1) how does the galaxy…

Nearby dwarf galaxies with extreme star formation rates: a window into dwarf-galaxy evolution in the early Universe

S. Kaviraj, B. Bichang'a, I. Lazar +3

We study a sample of nearby (z~0.2) low-luminosity dwarf (10^7 MSun < M* < 10^8 MSun) galaxies which have extreme (0.1 - 3 MSun/yr) star formation rates (SFRs) for this mass regime…

Cosmic reflections I: the structural diversity of simulated and observed low-mass galaxy analogues

G. Martin, A. E. Watkins, Y. Dubois +10

Dwarf galaxies serve as powerful laboratories for investigating the underlying physics of galaxy evolution including the impact of baryonic feedback processes and environmental inf…

The quenching of star formation in dwarf galaxies: new perspectives from deep-wide surveys

S. Kaviraj, I. Lazar, A. E. Watkins +3

Dwarf galaxies dominate the galaxy number density, making them critical to our understanding of galaxy evolution. However, typical dwarfs are too faint to be visible outside the ve…

2D light distributions of dwarf galaxies -- key tests of the implementation of physical processes in simulations

Aaron Watkins, Garreth Martin, Sugata Kaviraj +5

Cosmological simulations provide much of the theoretical framework within which we interpret extragalactic observations. However, even if a given simulation reproduces the integrat…
