Accelerating scaling solutions from dark matter particle creation
Sudip Halder, Jaume de Haro, Supriya Pan +3
This article opens new window to obtain accelerating scaling attractors without any need of dark energy. We study cosmological dynamics in a two-fluid system where pressureless dar…
Primordial black hole formation from transient cosmology
Gerasimos Kouniatalis, Theodoros Papanikolaou, Spyros Basilakos +1
We study primordial black hole (PBH) formation in a minimally coupled teleparallel cosmology that generates a transient departure from standard radiation domination. The mod…
Thermodynamically massless Simpson-Visser black holes
Thanasis Karakasis, Emmanuel N. Saridakis, Zi-Yu Tang
In this work we scrutinize the thermodynamic properties of the Simpson-Visser (SV) spacetime. Working within Einstein gravity coupled to nonlinear electrodynamics (NLED) and a scal…
Chaotic imprints of dark matter in extreme mass-ratio inspirals
Mustapha Azreg-Aïnou, Mubasher Jamil, Emmanuel N. Saridakis
Extreme mass-ratio inspirals (EMRIs) are among the most powerful probes of strong-field gravity and of the environments surrounding supermassive compact objects. Motivated by the e…
Modified Teleparallel Gravity, DESI BAO and the Tension
Mariam Bouhmadi-López, Carlos G. Boiza, Maria Petronikolou +1
We investigate whether late-time modifications of gravity in the teleparallel framework can impact the current tension in the Hubble constant , focusing on cosmology as…
Effect of noise characterization on the detection of mHz stochastic gravitational waves
Nikolaos Karnesis, Quentin Baghi, Jean-Baptiste Bayle +1
Pulsar timing arrays' hint for a stochastic gravitational-wave background (SGWB) leverages the expectations of a future detection in the millihertz band, particularly with the LISA…
