Geometry of transient gravitational waves and estimation of efficiencies of different detector configurations
Osvaldo M. Moreschi
This work introduces a geometrical method for analyzing transient gravitational waves recorded at interferometric observatories. This approach is intended to aid in assessing the p…
Synthetic gravitational lens image of the Sagittarius A black hole with a thin disk model
Ezequiel F. Boero, Osvaldo M. Moreschi
The images of Sagittarius A published by the Event Horizon Telescope (ETH) Collaboration in 2022 present features that were associated with an emission ring consistent with w…
Sky localization and polarization mode reconstruction of gravitational waves from GW170104 and GW150914
Osvaldo M. Moreschi
The detections\citep{KAGRA:2023pio,LIGOScientific:2019lzm} and analysis of gravitational waves(GWs) have introduced us in a new era of our understanding of the cosmos, providing ne…
Localization of GW190521 and reconstruction of the spin-2 gravitational-wave polarization modes
Osvaldo M. Moreschi
We report on the new developments of the procedure L2D+PMR for sky localization\citep{KAGRA:2013rdx} using data from two gravitational-wave detectors and the reconstruction of grav…
Perturbative and numerical approach to plasma strong lensing
Gabriel Crisnejo, Emanuel Gallo, Ezequiel Boero +1
{Using two different approaches, we study imaging in the strong lens regime taking into account the effects of plasmatic environments on light propagation. First, we extend the use…
Spherically symmetric black holes and affine-null metric formulation of Einstein's equations
Emanuel Gallo, Carlos Kozameh, Thomas Mädler +2
The definition of well-behaved coordinate charts for black hole spacetimes can be tricky, as they can lead for example to either unphysical coordinate singularities in the metric (…
