The Quasar Catalogue for S-PLUS DR4 (QuCatS) and the estimation of photometric redshifts
L. Nakazono, R. R. Valença, G. Soares +12
The advent of massive broad-band photometric surveys enabled photometric redshift estimates for unprecedented numbers of galaxies and quasars. These estimates can be improved using…
Unveiling the internal structure of Hercules supercluster
R. Monteiro-Oliveira, D. F. Morell, V. M. Sampaio +2
We have investigated the structure of the Hercules supercluster (SCL160) based on data originally extracted from the Sloan Digital Sky Survey SDSS-DR7. We have traced the mass dist…
J-PAS: Forecasts for dark matter - dark energy elastic couplings
David Figueruelo, Miguel Aparicio Resco, Florencia A. Teppa Pannia +21
We consider a cosmological model where dark matter and dark energy feature a coupling that only affects their momentum transfer in the corresponding Euler equations. We perform a f…
CODEX Weak Lensing Mass Catalogue and implications on the mass-richness relation
K. Kiiveri, D. Gruen, A. Finoguenov +19
The COnstrain Dark Energy with X-ray clusters (CODEX) sample contains the largest flux limited sample of X-ray clusters at . It was selected from ROSAT data in the…
CODEX Weak Lensing: Concentration of Galaxy Clusters at z ~ 0.5
N. Cibirka, E. S. Cypriano, F. Brimioulle +13
We present a stacked weak lensing analysis of 27 richness selected galaxy clusters at in the CODEX survey. The fields were observed in 5 bands wit…
Weak Lensing Calibrated M-T Scaling Relation of Galaxy Groups in the COSMOS Field
Kimmo Kettula, Alexis Finoguenov, Richard Massey +9
The scaling between X-ray observables and mass for galaxy clusters and groups is instrumental for cluster based cosmology and an important probe for the thermodynamics of the intra…
