Probing the stellar populations and star formation history of early-type galaxies at in the rest-frame ultraviolet
Sadman Ali, Roberto De Propris, Chul Chung +6
We measure the evolution of the rest-frame colors for early-type galaxies in clusters at using data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP),…
The Ultraviolet Upturn in field Luminous Red Galaxies at
R. De Propris, Sadman Ali, Chul Chung +2
We derive the evolution of the ultraviolet upturn colour from a sample of field luminous red galaxies at with . No individual objects are securel…
Passive spiral galaxies deeply captured by Subaru Hyper Suprime-Cam
Rhythm Shimakawa, Masayuki Tanaka, Connor Bottrell +4
This paper presents a thousand passive spiral galaxy samples at 0.01-0.3 based on a combined analysis of the Third Public Data Release of the Hyper Suprime-Cam Subaru Strategi…
Evolution of the Ultraviolet Upturn at : exploring helium rich stellar populations
S. S. Ali, R. De Propris, C. Chung +2
We measure the near-UV (rest-frame Å) to optical color for early-type galaxies in 12 clusters at . We show that this is a suitable proxy for the more comm…
Environmental Effects on the UV Upturn in Local Clusters of Galaxies
Sadman Ali, Malcolm Bremer, Steven Phillipps +1
We explore the dependence of UV upturn colours in early type cluster galaxies on the properties of their parent clusters (such as velocity dispersion and X-ray luminosity) and on t…
The rise and fall of the UV upturn: and
Sadman Ali, Malcolm Bremer, Steven Phillipps +7
We have analysed the strength of the UV upturn in red sequence galaxies with luminosities reaching to below the point within four clusters at = 0.3, 0.55 \& 0.7. We find…
