The developed methodology will be applied to future multi-filter surveys such as J-PAS.īased on observations collected at the German-Spanish Astronomical Center, Calar Alto (CAHA), jointly operated by the Max-Planck-Institut für Astronomie (MPIA) at Heidelberg and the Instituto de Astrofísica de Andalucía (CSIC) The contribution of the faint quiescent population to j B increases from 3% at z = 1 to 6% at z = 0. The application to ALHAMBRA shows a factor 2.55 ± 0.14 decrease in the luminosity density j B of star-forming galaxies, and a factor 1.25 ± 0.16 increase in the j B of quiescent ones since z = 1, confirming the continuous build-up of the quiescent population with cosmic time. We present a robust methodology to compute LFs using multi-filter photometric data. We find a significant population of faint quiescent galaxies with M B ≳ −18, modelled by a second Schechter function with slope β = −1.31 ± 0.11.Ĭonclusions. The measured ALHAMBRA LF at 0.2 ≤ z< 1 and the evolving Schechter parameters both for quiescent and star-forming galaxies agree with previous results in the literature.

We modelled the LF with a redshift-dependent Schechter function affected by the same selection effects than the data. The uncertainty due to the photometric redshift prior is also included in our analysis. That was estimated from the intrinsic dispersion of the LF measurements in the 48 ALHAMBRA sub-fields. The LF covariance matrix in redshift – magnitude – galaxy type space was computed, including the cosmic variance. We statistically studied quiescent and star-forming galaxies using the template information encoded in the PDFs. We used the photometric redshift and the I-band selection magnitude probability distribution functions (PDFs) of those ALHAMBRA galaxies with I ≤ 24 mag to compute the posterior LF. Our goal is to study the evolution of the B-band luminosity function (LF) since z ~ 1 using ALHAMBRA data. 782-0436 Santiago, ChileĢ1 Instituto de Física Teórica (UAM/CSIC), Universidad Autónoma de Madrid, Cantoblanco, 28049 Madrid, SpainĢ2 Campus of International Excellence UAM+CSIC, Cantoblanco, 28049 Madrid, SpainĪims.
