Deviations from the von Laue condition: Implications for the on-shell Lagrangian of particles and fluids
S. R. Pinto, P. P. Avelino
According to the von Laue condition, the volume integral of the proper pressure inside isolated particles with a fixed structure and finite mass vanishes in the Minkowski limit of…
Domain walls in light of Cosmic Microwave Background and Pulsar Timing Array data
D. Grüber, P. P. Avelino, L. Sousa
In this paper, we study the compatibility of biased domain wall scenarios with current gravitational wave data. We show that the Cosmic Microwave Background bounds on the fractiona…
Particles and their fluids in nontrivial matter extensions to general relativity
P. P. Avelino
According to the standard von Laue condition, the volume-averaged pressure inside particles of fixed mass and structure vanishes in the Minkowski limit of general relativity. Here…
Sound speed as a source of the gravitational field in modified gravity
P. P. Avelino
In the context of gravity and other modified theories of gravity, the knowledge of the first order variation of the trace of the energy-momentum tensor with respect to…
Stochastic gravitational wave background generated by domain wall networks
D. Grüber, L. Sousa, P. P. Avelino
In this work we study the power spectrum of the Stochastic Gravitational Wave Background produced by standard and biased domain wall networks, using the Velocity-dependent One-Scal…
Can gravitational vacuum condensate stars be a dark energy source?
P. P. Avelino
Gravitational vacuum condensate stars, also known as gravastars, have been proposed as an alternative to black holes. Their interior contains a perfect fluid with an equation of st…
Could the dynamics of the Universe be influenced by what is going on inside black holes?
P. P. Avelino
We investigate the potential impact of mass inflation inside black holes on the dynamics of the Universe, considering a recent reformulation of general relativity, proposed in [1],…
