Spectro-Imaging Forward Model of Red and Blue Galaxies

Martina Fagioli, Luca Tortorelli, Jörg Herbel +3

For the next generation of spectroscopic galaxy surveys, it is important to forecast their performances and to accurately interpret their large data sets. For this purpose, it is n…

Measurement of the B-band Galaxy Luminosity Function with Approximate Bayesian Computation

Luca Tortorelli, Martina Fagioli, Jörg Herbel +3

The galaxy Luminosity Function (LF) is a key observable for galaxy formation, evolution studies and for cosmology. In this work, we propose a novel technique to forward model wide-…

The PAU Survey: Early demonstration of photometric redshift performance in the COSMOS field

M. Eriksen, A. Alarcon, E. Gaztanaga +22

The PAU Survey (PAUS) is an innovative photometric survey with 40 narrow bands at the William Herschel Telescope (WHT). The narrow bands are spaced at 100Å intervals covering the r…

The PAU Survey: Spectral features and galaxy clustering using simulated narrow band photometry

L. Stothert, P. Norberg, C. M. Baugh +14

We present a mock catalogue for the Physics of the Accelerating Universe Survey (PAUS) and use it to quantify the competitiveness of the narrow band imaging for measuring spectral…

A catalogue of structural and morphological measurements for DES Y1

F. Tarsitano, W. G. Hartley, A. Amara +60

We present a structural and morphological catalogue for 45 million objects selected from the first year of data from the Dark Energy Survey (DES). Single Sersic fits and non-parame…

The PAU Survey: A Forward Modeling Approach for Narrow-band Imaging

Luca Tortorelli, Lorenza Della Bruna, Jörg Herbel +15

Weak gravitational lensing is a powerful probe of the dark sector, once measurement systematic errors can be controlled. In Refregier & Amara (2014), a calibration method based on…
