Prospects for the Observation of Continuous Gravitational Waves from Deformed Fast-spinning White Dwarfs
M. F. Sousa, E. Otoniel, J. G. Coelho +1
There has been a growing interest within the astrophysics community in highly magnetized and fast-spinning white dwarfs (WDs), commonly referred to as HMWDs. WDs with these charact…
Testing beyond-Kerr spacetimes with GWTC-3
Rafael M. Santos, Rafael C. Nunes, Jose C. N. de Araujo
The Kerr spacetime is a fundamental solution of general relativity (GR), describing the gravitational field around a rotating, uncharged black hole (BH). Kerr spacetime has been cr…
Compact stars in gravity
José C. N. de Araujo, Hemily G. M. Fortes
The Teleparallel Theory is equivalent to General Relativity, but whereas in the latter gravity has to do with curvature, in the former gravity is described by torsion. As is well k…
Evidence for 3XMM J185246.6+003317 as a massive magnetar with a low magnetic field
Rafael C. R. de Lima, Jonas P. Pereira, Jaziel G. Coelho +10
3XMM J185246.6+003317 is a transient magnetar located in the vicinity of the supernova remnant Kes\,79. So far, observations have only set upper limits to its surface magnetic fiel…
Gravitational Wave Emission by Accretion of Matter and Magnetic Deformation in Fast Rotating White Dwarfs
Manoel F. Sousa, José C. N. de Araujo, Jaziel G. Coelho
We discuss some aspects of Sousa et al.(2020a, 2020b) concerning two mechanisms of gravitational wave (GW) emission in fast-spinning white dwarfs (WDs): accretion of matter and mag…
Minimal theory of massive gravity in the light of CMB data and the tension
Jose C. N. de Araujo, Antonio De Felice, Suresh Kumar +1
We investigate the Minimal Theory of Massive Gravity (MTMG) in the light of different observational data sets which are in tension within the CDM cosmology. In particular, we an…
Coherent observations of gravitational radiation with LISA and gLISA
Massimo Tinto, Jose' Carlos N. de Araujo
The geosynchronous Laser Interferometer Space Antenna (gLISA) is a space-based gravitational wave (GW) mission that, for the past five years, has been under joint study at the Jet…
