First fast radio burst search campaign at the Argentine Institute of Radio Astronomy

Carlos O. Lousto, Harsh Prajapati, Ezequiel Zubieta +7

Fast radio bursts (FRBs) are intense millisecond-duration radio transients of extragalactic origin whose physical nature remains under active investigation, and which also serve as…

Accretion-powered flares from black hole-disk collisions in galactic nuclei

Joaquin Pelle, Kyohei Kawaguchi, Masaru Shibata +1

Black hole impacts on accretion disks in galactic nuclei can power luminous transients, but predicting their observable signatures is challenging because the post-collision flow is…

Black hole-accretion disk collision in general relativity: Axisymmetric simulations

Alan Tsz-Lok Lam, Masaru Shibata, Kyohei Kawaguchi +1

Motivated by recent discoveries of X-ray quasi-periodic eruptions, we revisit the collision of a black hole and an accretion disk. Assuming that they are orbiting a supermassive bl…

Imaging fermionic dark matter cores at the center of galaxies

Joaquin Pelle, Carlos R. Argüelles, Florencia L. Vieyro +5

Current images of the supermassive black hole (SMBH) candidates at the center of our Galaxy and M87 have opened an unprecedented era for studying strong gravity and the nature of r…

A Parameter Study of the Electromagnetic Signatures of an Analytical Mini-Disk Model for Supermassive Binary Black Hole Systems

Kaitlyn Porter, Scott C. Noble, Eduardo M. Gutierrez +4

Supermassive black holes (SMBHs) are thought to be located at the centers of most galactic nuclei. When galaxies merge they form supermassive black hole binary (SMBHB) systems and…

Accretion disks and relativistic line broadening in boson star spacetimes

João Luís Rosa, Joaquín Pelle, Daniela Pérez

In this work, we analyze the observational properties of static, spherically symmetric boson stars with fourth and sixth-order self-interactions, using the Julia-based general-rela…

The Shadow of Charged Traversable Wormholes

Mário Raia Neto, Daniela Pérez, Joaquín Pelle

We compute the shadow cast by a charged Morris-Thorne wormhole when the light source is a star located beyond the mouth which is opposite to the observer. First, we provide an exte…

Relativistic force-free models of the thermal X-ray emission in millisecond pulsars observed by NICER

Federico Carrasco, Joaquin Pelle, Oscar Reula +2

Several important properties of rotation-powered millisecond pulsars (MSPs), such as their mass-radius ratio, equation of state and magnetic field topology, can be inferred from pr…

Skylight: a new code for general-relativistic ray-tracing and radiative transfer in arbitrary spacetimes

Joaquín Pelle, Oscar Reula, Federico Carrasco +1

To reproduce the observed spectra and light curves originated in the neighborhood of compact objects requires accurate relativistic ray-tracing codes. In this work, we present Skyl…
