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…
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…
The structural properties of nearby dwarf galaxies in low density environments -- size, surface brightness and colour gradients
Ilin Lazar, Sugata Kaviraj, Aaron E. Watkins +3
We use a complete sample of 211 nearby (z<0.08) dwarf (10^8 MSun < Mstar < 10^9.5 Msun) galaxies in low-density environments, to study their structural properties: effective radii…
The properties of AGN in dwarf galaxies identified via SED fitting
B. Bichang'a, S. Kaviraj, I. Lazar +5
Given their dominance of the galaxy number density, dwarf galaxies are central to our understanding of galaxy formation. While the incidence of AGN and their impact on galaxy evolu…
The morphological mix of dwarf galaxies in the nearby Universe
Ilin Lazar, Sugata Kaviraj, Aaron E. Watkins +3
We use a complete, unbiased sample of 257 dwarf (10^8 MSun < Mstar < 10^9.5 MSun) galaxies at z < 0.08, in the COSMOS field, to study the morphological mix of the dwarf population…
The formation of cores in galaxies across cosmic time -- the existence of cores is not in tension with the LCDM paradigm
R. A. Jackson, S. Kaviraj, S. K. Yi +9
The `core-cusp' problem is considered a key challenge to the LCDM paradigm. Halos in dark matter only simulations exhibit `cuspy' profiles, where density continuously increases tow…
