⋆ Galaxy luminosity function per morphological type up to z = 1.2 Abstract. We have computed the evolution of the rest-frame B-band luminosity function (LF) for bulge and disk-dominated galaxies since z = 1.2. We use a sample of 605 spectroscopic redshifts with IAB ≤ 24 in the Chandra Deep Field South from the VIMOS-VLT Deep Survey, 3555 galaxies with(More)
To understand the evolution of galaxies, we need to know as accurately as possible how many galaxies were present in the Universe at different epochs. Galaxies in the young Universe have hitherto mainly been identified using their expected optical colours, but this leaves open the possibility that a significant population remains undetected because their(More)
We present a quasar candidate identification technique based on multicolor photometry. The traditional multi-dimensional method (2 × N dimensions, where N is the number of the color-color diagrams) is reduced to a one-dimensional technique, which consists in a standard fitting procedure, where the observed spectral energy distributions are compared to(More)
