Probing the statistical isotropy of the universe with Planck data of the cosmic microwave background
C. E. Kester, A. Bernui, W. S. Hipólito-Ricaldi
We study the angular distribution of temperature fluctuations in the cosmic microwave background (CMB) to probe the statistical isotropy of the universe by using precise full-sky C…
Cosmography from well-localized Fast Radio Bursts
Jéferson A. S. Fortunato, Wiliam S. Hipólito-Ricaldi, Marcelo V. dos Santos
Fast Radio Bursts (FRBs) are millisecond-duration pulses occurring at cosmological distances that have emerged as prominent cosmological probes due to their dispersion measure (DM)…
Particle Production in Ekpyrotic Scenarios
W. S. Hipolito-Ricaldi, Robert Brandenberger, Elisa G. M. Ferreira +1
We consider Parker particle production in the Ekpyrotic scenario (in particular in the New Ekpyrotic model) and show that the density of particles produced by the end of the phase…
Interacting dark energy and transient accelerated expansion
W. Zimdahl, C. Z. Vargas, W. S. Hipólito-Ricaldi
We argue that interactions in the dark sector may have a crucial impact on the cosmological dynamics. In particular, the future cosmic evolution may be very different from that pre…
