Merger History of Galaxies and Disk+Bulge Formation
S. Khochfar
We discuss the transitions of galaxy morphologies within the CDM paradigm under the assumption of bulge formation in mergers and disk growth via cooling of gas and subsequent star…
Recent star formation in high-redshift early-type galaxies: insights from the rest-frame UV
S. Kaviraj, S. K. Yi, E. Gawiser +4
We combine deep UBVRIzJK photometry from the MUSYC survey with redshifts from the COMBO-17 survey to study the rest-frame ultraviolet (UV) properties of 674 high-redshift (0.5<z<1)…
The role of minor mergers in the recent star formation history of early-type galaxies
Sugata Kaviraj, Sebastien Peirani, Sadegh Khochfar +2
We demonstrate that the large scatter in the ultra-violet (UV) colours of intermediate-mass early-type galaxies in the local Universe and the inferred low-level recent star formati…
The UV colours of high-redshift early-type galaxies: evidence for recent star formation and stellar mass assembly over the last 8 billion years
S. Kaviraj, S. Khochfar, K. Schawinski +7
We combine deep UBVRIzJK photometry from the Multiwavelength Survey by Yale-Chile (MUSYC) with redshifts from the COMBO-17 survey to perform a large-scale study of the rest-frame u…
The hierarchical build-up of bulges in CDM
S. Khochfar
We investigate the hierarchical build-up of stars in bulges within the standard -cold dark matter scenario. By separating the population into stars born during starbursts that a…
The Evolving Faint-End of the Luminosity Function
S. Khochfar, J. Silk, R. A. Windhorst +1
We investigate the evolution of the faint-end slope of the luminosity function, , using semi-analytical modeling of galaxy formation. In agreement with observations, we find tha…
