The PAU Survey: Active galactic nucleus galaxies in galaxy pairs
F. Duplancic, M. Siudek, D. Navarro-Gironés +21
Aims. Leveraging the high-precision photometric redshifts of the Physics of the Accelerating Universe Survey (PAUS), we aim to investigate the connection between active galactic nu…
Beyond traditional emission-line diagnostics: using autoencoders to uncover active galactic nuclei in DESI spectra
J. A. Alcolea, M. Siudek, M. Eriksen +49
The growing volume of spectroscopic data in modern surveys motivates data-driven approaches that complement traditional emission-line diagnostics for active galactic nuclei (AGN) i…
Joint probabilistic inference of galaxy redshifts and rest-frame spectra from photometric fluxes with latent diffusion
Han-Yue Guo, Martin Eriksen
Wide-field imaging surveys now provide photometry for billions of sources, while spectroscopic observations remain limited, motivating methods that can extract spectroscopic inform…

The PAU Survey: The quasar UV and Ly luminosity functions at
Alberto Torralba-Torregrosa, Pablo Renard, Daniele Spinoso +17
We present the Lyman- (Ly) and ultraviolet (UV) luminosity function (LF), in bins of redshift, of quasars selected in the Physics of the Accelerating Universe Survey (PAUS).…
The PAU Survey: galaxy stellar population properties estimates with narrowband data
Benjamin Csizi, Luca Tortorelli, Małgorzata Siudek +17
Narrowband galaxy surveys have recently gained interest as a promising method to achieve the necessary accuracy on the photometric redshift estimate of individual galaxies for stag…
The PAU Survey: a new constraint on galaxy formation models using the observed colour redshift relation
G. Manzoni, C. M. Baugh, P. Norberg +27
We use the GALFORM semi-analytical galaxy formation model implemented in the Planck Millennium N-body simulation to build a mock galaxy catalogue on an observer's past lightcone. T…
The PAU Survey: Close galaxy pairs identification and analysis
E. J. Gonzalez, F. Rodriguez, D. Navarro-Gironés +18
Galaxy pairs constitute the initial building blocks of galaxy evolution, which is driven through merger events and interactions. Thus, the analysis of these systems can be valuable…
The PAU Survey: Measurements of the 4000 Å spectral break with narrow-band photometry
Pablo Renard, Małgorzata Siudek, Martin B. Eriksen +19
The D4000 spectral break index is one of the most important features in the visible spectrum, as it is a proxy for stellar ages and is also used in galaxy classification. However,…
The PAU Survey: Measurement of Narrow-band galaxy properties with Approximate Bayesian Computation
Luca Tortorelli, Malgorzata Siudek, Beatrice Moser +22
Narrow-band imaging surveys allow the study of the spectral characteristics of galaxies without the need of performing their spectroscopic follow-up. In this work, we forward-model…
