Observational Constraints on the Pulsar Wind Model: The Cases of Crab and Vela
Jaziel G. Coelho, José C. N. de Araujo, Samantha M. Ladislau +1
As is well known, pulsars are extremely stable rotators. However, although slowly, they spin down thanks to brake mechanisms, which are in fact still subject of intense investigati…
Weighing massive neutron star with screening gravity: A look on PSR J0740+6620 and GW190814 secondary component
Rafael C. Nunes, Jaziel G. Coelho, José C. N. de Araujo
Neutron stars (NSs) are excellent natural laboratories to constrain gravity on strong field regime and nuclear matter in extreme conditions. Motivated by the recent discovery of a…
Gravitational waves from SGRs and AXPs as fast-spinning white dwarfs
Manoel F. Sousa, Jaziel G. Coelho, José C. N. de Araujo
Gravitational waves (GWs) emission due to magnetic deformation mechanism is applied for Soft Gamma Repeaters (SGRs) and Anomalous X-Ray Pulsars(AXPs), described as fast-spinning an…
Forecasts on the speed of gravitational waves at high
Alexander Bonilla, Rocco D'Agostino, Rafael C. Nunes +1
The observation of GW170817 binary neutron star (BNS) merger event has imposed strong bounds on the speed of gravitational waves (GWs) locally, inferring that the speed of GWs prop…
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…
