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…
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…
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…
