Improved strong lensing modelling of galaxy clusters using the Fundamental Plane: detailed mapping of the baryonic and dark matter mass distribution of Abell S1063
Giovanni Granata
Strong gravitational lensing (SL) has emerged as a very accurate probe of the mass distribution of cluster- and galaxy-scale dark matter (DM) haloes in the inner regions of galaxy…
The PAU Survey: Intrinsic alignments and clustering of narrow-band photometric galaxies
Harry Johnston, Benjamin Joachimi, Peder Norberg +20
We present the first measurements of the projected clustering and intrinsic alignments (IA) of galaxies observed by the Physics of the Accelerating Universe Survey (PAUS). With pho…
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: Background light estimation with deep learning techniques
Laura Cabayol-Garcia, Martin B. Eriksen, Àlex Alarcón +17
In any imaging survey, measuring accurately the astronomical background light is crucial to obtain good photometry. This paper introduces BKGnet, a deep neural network to predict t…
The PAU Survey: Operation and orchestration of multi-band survey data
Nadia Tonello, Pau Tallada, Santiago Serrano +14
The Physics of the Accelerating Universe (PAU) Survey is an international project for the study of cosmological parameters associated with Dark Energy. PAU's 18-CCD camera (PAUCam)…
