Infrared-enhanced Photometric Redshifts for the Dark Energy Survey Y6 Gold catalogue
M. M. Puebla, I. Sevilla-Noarbe, J. de Vicente +13
The Dark Energy Survey (DES) provides optical data across 5000 square degrees of the southern sky, enabling a broad range of extragalactic and cosmological studies. Combining DES d…
GTC Follow-up Observations of Very Metal-Poor Star Candidates from DESI
Carlos Allende Prieto, David S. Aguado, Jonay I. González Hernández +48
The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ~ 10, improving the…
Dark Energy Survey Year 3 results: Marginalisation over redshift distribution uncertainties using ranking of discrete realisations
Juan P. Cordero, Ian Harrison, Richard P. Rollins +92
Cosmological information from weak lensing surveys is maximised by dividing source galaxies into tomographic sub-samples for which the redshift distributions are estimated. Uncerta…
The PAU survey: Estimating galaxy photometry with deep learning
Laura Cabayol, Martin Eriksen, Adam Amara +14
With the dramatic rise in high-quality galaxy data expected from Euclid and Vera C. Rubin Observatory, there will be increasing demand for fast high-precision methods for measuring…
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: star-galaxy classification with multi narrow-band data
Laura Cabayol, Ignacio Sevilla-Noarbe, Enrique Fernández +18
Classification of stars and galaxies is a well-known astronomical problem that has been treated using different approaches, most of them relying on morphological information. In th…
DES Science Portal: Computing Photometric Redshifts
Julia Gschwend, Aurelio Carnero Rosell, Ricardo Ogando +68
A significant challenge facing photometric surveys for cosmological purposes is the need to produce reliable redshift estimates. The estimation of photometric redshifts (photo-zs)…
Weak lensing magnification in the Dark Energy Survey Science Verification Data
M. Garcia-Fernandez, E. Sánchez, I. Sevilla-Noarbe +68
In this paper the effect of weak lensing magnification on galaxy number counts is studied by cross-correlating the positions of two galaxy samples, separated by redshift, using dat…
Homogeneity and isotropy in the 2MASS Photometric Redshift catalogue
David Alonso, Ana Isabel Salvador, Francisco Javier Sánchez +3
Using the 2MASS Photometric Redshift catalogue we perform a number of statistical tests aimed at detecting possible departures from statistical homogeneity and isotropy in the larg…
Photometric redshift analysis in the Dark Energy Survey Science Verification data
C. Sánchez, M. Carrasco Kind, H. Lin +74
We present results from a study of the photometric redshift performance of the Dark Energy Survey (DES), using the early data from a Science Verification (SV) period of observation…
Measuring the transition to homogeneity with photometric redshift surveys
D. Alonso, A. Bueno Belloso, F. J. Sánchez +2
We study the possibility of detecting the transition to homogeneity using photometric redshift catalogs. Our method is based on measuring the fractality of the projected galaxy dis…
