Dark Energy Survey Year 1 Results: The effect of intracluster light on photometric redshifts for weak gravitational lensing
D. Gruen, Y. Zhang, A. Palmese +64
We study the effect of diffuse intracluster light on the critical surface mass density estimated from photometric redshifts of lensing source galaxies, and the resulting bias in a…
{\it Gauging} the cosmic acceleration with recent type Ia supernovae data sets
Hermano Velten, Syrios Gomes, Vinicius C. Busti
We revisit a model-independent estimator for cosmic acceleration based on type Ia supernovae distance measurements. This approach does not rely on any specific theory for gravity,…
Cosmological constraints on the gas depletion factor in galaxy clusters
R. F. L. Holanda, V. C. Busti, J. E. Gonzalez +2
The evolution of the X-ray emitting gas mass fraction () in massive galaxy clusters can be used as an independent cosmological tool to probe the expansion history of the U…
Probing the distance-duality relation with high- data
R. F. L. Holanda, V. C. Busti, F. S. Lima +1
Measurements of strong gravitational lensing jointly with type Ia supernovae (SNe Ia) observations have been used to test the validity of the cosmic distance duality relation (CDDR…
Testing the cosmic conservation of photon number with type Ia supernovae and ages of old objects
J. F. Jesus, R. F. L. Holanda, M. A. Dantas
In this paper, we obtain luminosity distances by using ages of 32 old passive galaxies distributed over the redshift interval and test the cosmic conservation of…
Exploring the spectroscopic diversity of type Ia supernovae with DRACULA: a machine learning approach
Michele Sasdelli, E. E. O. Ishida, R. Vilalta +8
The existence of multiple subclasses of type Ia supernovae (SNeIa) has been the subject of great debate in the last decade. One major challenge inevitably met when trying to infer…
