The Gravitational Lensing Imprints of DES Y3 Superstructures on the CMB: A Matched Filtering Approach
Umut Demirbozan, Seshadri Nadathur, Ismael Ferrero +63
Low density cosmic voids gravitationally lens the cosmic microwave background (CMB), leaving a negative imprint on the CMB convergence . This effect provides insight into the…
Copacabana: A Probabilistic Membership Assignment Method for Galaxy Clusters
J. H. Esteves, M. E. S. Pereira, M. Soares-Santos +52
Cosmological analyses using galaxy clusters in optical/NIR photometric surveys require robust characterization of their galaxy content. Precisely determining which galaxies belong…
The Dark Energy Survey Supernova Program: Modelling selection efficiency and observed core collapse supernova contamination
M. Vincenzi, M. Sullivan, O. Graur +79
The analysis of current and future cosmological surveys of type Ia supernovae (SNe Ia) at high-redshift depends on the accurate photometric classification of the SN events detected…
Cosmological Constraints from Multiple Probes in the Dark Energy Survey
DES Collaboration, T. M. C. Abbott, A. Alarcon +166
The combination of multiple observational probes has long been advocated as a powerful technique to constrain cosmological parameters, in particular dark energy. The Dark Energy Su…
