Testing the accuracy of likelihoods for cluster abundance cosmology
Constantin Payerne, Calum Murray, Céline Combet +3
The abundance of galaxy clusters is a sensitive probe to the amplitude of matter density fluctuations, the total amount of matter in the Universe as well as its expansion history.…
New formalism to define vacuum states for scalar fields in curved space-times
Mariana Penna-Lima, Nelson Pinto-Neto, Sandro D. P. Vitenti
The problem of finding a vacuum definition for a single quantum field in curved space-times is discussed under a new geometrical perspective. The phase space dynamics of the quantu…
Cosmologia com aglomerados de galáxias
M. Penna-Lima
Galaxy clusters are important cosmological probes since their abundance and spatial distribution are directly linked to structure formation on large scales. The principal uncertain…
