Upper Bound of Neutrino Masses from Combined Cosmological Observations and Particle Physics Experiments
Arthur Loureiro, Andrei Cuceu, Filipe B. Abdalla +9
We investigate the impact of prior models on the upper bound of the sum of neutrino masses, . We use data from Large Scale Structure of galaxies, Cosmic Microwave Backgro…
Convolutional Neural Networks for Spectroscopic Redshift Estimation on Euclid Data
Radamanthys Stivaktakis, Grigorios Tsagkatakis, Bruno Moraes +3
In this paper, we address the problem of spectroscopic redshift estimation in Astronomy. Due to the expansion of the Universe, galaxies recede from each other on average. This move…
Cosmological Measurements from Angular Power Spectra Analysis of BOSS DR12 Tomography
Arthur Loureiro, Bruno Moraes, Filipe B. Abdalla +9
We constrain cosmological parameters by analysing the angular power spectra of the Baryon Oscillation Spectroscopic Survey DR12 galaxies, a spectroscopic follow-up of around 1.3 mi…
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…
Star-galaxy classification in the Dark Energy Survey Y1 dataset
I. Sevilla-Noarbe, B. Hoyle, M. J. Marchã +75
We perform a comparison of different approaches to star-galaxy classification using the broad-band photometric data from Year 1 of the Dark Energy Survey. This is done by performin…
Degradation analysis in the estimation of photometric redshifts from non-representative training sets
J. D. Rivera, B. Moraes, A. I. Merson +3
We perform an analysis of photometric redshifts estimated by using a non-representative training sets in magnitude space. We use the ANNz2 and GPz algorithms to estimate the photom…
