The alhambra survey: evolution of galaxy spectral segregation [Article]
(IOP Publishing Ltd., 2016-02-20)
We study the clustering of galaxies as a function of spectral type and redshift in the range 0.35 <z <1.1 using data from the Advanced Large Homogeneous Area Medium Band Redshift Astronomical (ALHAMBRA) survey. The data ...
The ALHAMBRA survey: Bayesian photometric redshifts with 23 bands for 3 deg2 [Article]
(Oxford University Press, 2014)
The Advance Large Homogeneous Area Medium-Band Redshift Astronomical (ALHAMBRA) survey has observed eight different regions of the sky, including sections of the Cosmic Evolution Survey (COSMOS), DEEP2, European Large-Area ...
The ALHAMBRA survey: Discovery of a faint QSO at z = 5.41 (Research Note) [Article]
(Hans Publishers, 2013)
Aims. We aim to illustrate the potentiality of the Advanced Large, Homogeneous Area, Medium-Band Redshift Astronomical (ALHAMBRA) survey to investigate the high-redshift universe through the detection of quasi stellar ...
The alhambra photometric system [Article]
(IOP Publishing Ltd., 2010-03)
This paper presents the characterization of the optical range of the ALHAMBRA photometric system, a 20 contiguous, equal-width, medium-band CCD system with wavelength coverage from 3500 Å to 9700 Å. The photometric description ...
Optimal filter systems for photometric redshift estimation [Article]
(IOP Publishing Ltd., 2009)
In the coming years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narrower filters improve the spectral resolution, ...
