Testing gravity with gauge-invariant polarization states of gravitational waves: Theory and pulsar timing sensitivity
Márcio E. S. Alves
The determination of the polarization modes of gravitational waves (GWs) and their dispersion relations is a crucial task for scrutinizing the viability of extended theories of gra…
Cosmological Constraints on (t)CDM Models
H. A. P. Macedo, L. S. Brito, J. F. Jesus +1
Problems with the concordance cosmology CDM as the cosmological constant problem, coincidence problems and Hubble tension has led to many proposed alternatives, as the CDM…
Forecast constraints on gravity with gravitational waves from compact binary coalescences
Rafael C. Nunes, Marcio E. S. Alves, Jose C. N. de Araujo
The direct detection of gravitational waves (GWs) opened a new chapter in the modern cosmology to probe possible deviations from the general relativity (GR) theory. In the present…
Misaligned snowplough effect and the electromagnetic counterpart to black hole binary mergers
Fabrícia A. C. Pereira, Giuseppe Lodato, Irapuan Rodrigues +2
We estimate the accretion rates produced when a circumprimary gas disc is pushed into the primary supermassive black hole (SMBH) by the tidal force of the decaying secondary during…
Primordial gravitational waves in Horndeski gravity
Rafael C. Nunes, Marcio E. S. Alves, Jose C. N. de Araujo
We investigate the propagation of primordial gravitational waves within the context of the Horndeski theories, for this, we present a generalized transfer function quantifying the…
An unified cosmological evolution driven by a mass dimension one fermionic field
S. H. Pereira, M. E. S. Alves, T. M. Guimarães
An unified cosmological model for an Universe filled with a mass dimension one (MDO) fermionic field plus the standard matter fields is considered. After a primordial quantum fluct…
