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 star formation histories of early-type galaxies: insights from the rest-frame ultra-violet
S. Kaviraj
Our current understanding of the star formation histories of early-type galaxies is reviewed, in the context of recent observational studies of their ultra-violet (UV) properties.…
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…
Decoding the spectra of SDSS early-type galaxies: New indicators of age and recent star formation
Ben Rogers, Ignacio Ferreras, Ofer Lahav +3
(Abridged) We apply Principal Component Analysis (PCA) to a sample of early-type galaxies from the Sloan Digital Sky Survey (SDSS) in order to infer differences in their star forma…
The UV properties of E+A galaxies: constraints on feedback-driven quenching of star formation
S. Kaviraj, L. A. Kirkby, J. Silk +1
We present the first large-scale study of E+A (post-starburst) galaxies that incorporates photometry in the ultraviolet (UV) wavelengths. We find that the starburst that creates th…
