Abstract:

The ultraviolet (UV) upturn phenomenon in elliptical galaxies has attracted much attention as it violates the common understanding that early type galaxies are mostly comprised of old stars with little UV radiation. Although there have been several recent samples of UV-upturn detections at low redshift (z<0.5), the analysis at high z is still lacking. In this work, we try to address this by measuring UV-upturn elliptical galaxies at 0.92 which hard to be explained by the binary star model on its own. More importantly, we managed to explore the distribution of specific UV-upturn radiative zone with galaxy radius in our sample.
