Astroinformatics of galaxies and quasars: a new general method for photometric redshifts estimation
cosmology: observations galaxies: redshifts methods: data mining surveys
2011/10/10
With the availability of the huge amounts of data produced by current and future large multi-band photometric surveys, photometric redshifts have become a crucial tool for extragalactic astronomy and ...
Discovering the missing 2.2quasars by combining optical variability and optical/near-IR colors
Discovering missing quasars combining variability optical/near-IR colors
2011/9/27
The identifications of quasars in the redshift range 2.2are known to be very inefficient as their optical colors are indistinguishable from those of stars. Recent studies have proposed to use opt...
