Baryon acoustic oscillations signature in the three-point angular correlation function from the SDSS-DR12 quasar survey
E. de Carvalho, A. Bernui, H. S. Xavier +1
The clustering properties of the Universe at large-scales are currently being probed at various redshifts through several cosmological tracers and with diverse statistical estimato…
The S-PLUS: a star/galaxy classification based on a Machine Learning approach
M. V. Costa-Duarte, L. Sampedro, A. Molino +32
We present a star/galaxy classification for the Southern Photometric Local Universe Survey (S-PLUS), based on a Machine Learning approach: the Random Forest algorithm. We train the…
The Southern Photometric Local Universe Survey (S-PLUS): improved SEDs, morphologies and redshifts with 12 optical filters
C. Mendes de Oliveira, T. Ribeiro, W. Schoenell +142
The Southern Photometric Local Universe Survey (S-PLUS) is imaging ~9300 deg^2 of the celestial sphere in twelve optical bands using a dedicated 0.8 m robotic telescope, the T80-So…
Largest scales from the largest galaxy surveys: the pseudo Karhunen-Loève method
Henrique S. Xavier
The increasing area and depth of galaxy surveys will give us access to the largest scales in the Universe and allow for a direct test of the primordial power spectrum set by inflat…
J-PAS: forecasts on interacting dark energy from baryon acoustic oscillations and redshift-space distortions
A. A. Costa, R. J. F. Marcondes, R. G. Landim +14
We estimate the constraining power of J-PAS for parameters of an interacting dark energy cosmology. The survey is expected to map several millions of luminous red galaxies, emissio…
All-sky angular power spectra from cleaned WISESuperCOSMOS galaxy number counts
H. S. Xavier, M. V. Costa-Duarte, A. Balaguera-Antolínez +1
Aiming to extract cosmological information from linear scales of the WISESuperCOSMOS photometric redshift catalog, we perform a characterization of the systematic effects a…
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…
J-PLUS: analysis of the intracluster light in the Coma cluster
Y. Jiménez-Teja, R. A. Dupke, R. Lopes de Oliveira +19
The intracluster light (ICL) is a luminous component of galaxy clusters composed of stars that are gravitationally bound to the cluster potential but do not belong to the individua…
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…
Tomographic local 2D analyses of the WISExSuperCOSMOS all-sky galaxy catalogue
Camila P. Novaes, Armando Bernui, Henrique S. Xavier +1
The recent progress in obtaining larger and deeper galaxy catalogues is of fundamental importance for cosmological studies, especially to robustly measure the large scale density f…
J-PLUS: The Javalambre Photometric Local Universe Survey
A. J. Cenarro, M. Moles, D. Cristóbal-Hornillos +119
J-PLUS is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the Observatorio…
The dipole anisotropy of WISE x SuperCOSMOS number counts
C. A. P. Bengaly, C. P. Novaes, H. S. Xavier +3
We probe the isotropy of the Universe with the largest all-sky photometric redshift dataset currently available, namely WISE~~SuperCOSMOS. We search for dipole anisotropy o…
Is there evidence for anomalous dipole anisotropy in the large-scale structure?
C. A. P. Bengaly, A. Bernui, J. S. Alcaniz +2
We probe the anisotropy of the large-scale structure (LSS) with the WISE-2MASS catalogue. This analysis is performed by a directional comparison of the galaxy number counts through…
Improving lognormal models for cosmological fields
Henrique S. Xavier, Filipe B. Abdalla, Benjamin Joachimi
It is common practice in cosmology to model large-scale structure observables as lognormal random fields, and this approach has been successfully applied in the past to the matter…
