Observational signatures of negative mass wormholes through their shadows
Shin'ichi Nojiri, Sergei D. Odintsov, Diego Sáez-Chillón Gómez
Systems containing objects with negative mass (NMOs) are considered. Such a system consists of one object with positive mass and one NMO, where a bound state exists even though the…
Propagation and emission of gravitational waves in the weak-field limit within the Palatini formalism
Albert Duran-Cabacés, Diego Sáez-Chillón Gómez
In the era of gravitational waves physics, when detections of wave fronts are increasing in number, sensibility, frequencies and distances, gravitational physics has entered a peri…
Shadows and photon rings of regular black holes and geonic horizonless compact objects
Gonzalo J. Olmo, João Luís Rosa, Diego Rubiera-Garcia +1
The optical appearance of a body compact enough to feature an unstable bound orbit, when surrounded by an accretion disk, is expected to be dominated by a luminous ring of radiatio…
Eternal vs singular observers in interacting dark energy-dark matter models
Diego Álvarez-Ortega, Gonzalo J. Olmo, Diego Rubiera-García +1
Interacting dark energy-dark matter models have been widely analyzed in the literature in an attempt to find traces of new physics beyond the usual cosmological (CDM) models. Su…
