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…
Delayed jet launching in binary neutron star mergers with realistic initial magnetic fields
Ricard Aguilera-Miret, Carlos Palenzuela, Federico Carrasco +2
We analyze a long-lived hyper-massive neutron star merger remnant (post-merger lifetime ms) that has been obtained via large eddy simulations with a gradient subgrid-scale m…
The role of turbulence and winding in the development of large-scale, strong magnetic fields in long-lived remnants of binary neutron star mergers
Ricard Aguilera-Miret, Carlos Palenzuela, Federico Carrasco +1
We perform a long and accurate Large-Eddy Simulation of a binary neutron star merger, following the newly formed remnant up to 110 milliseconds. The combination of high-order schem…
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…
