Electromagnetic Signatures from Supermassive Binary Black Holes Approaching Merger
Eduardo M. Gutiérrez, Luciano Combi, Scott C. Noble +4
We present fully relativistic predictions for the electromagnetic emission produced by accretion disks surrounding spinning and nonspinning supermassive binary black holes on the v…
Vela Pulsar: Single Pulses Analysis with Machine Learning Techniques
Carlos O. Lousto, Ryan Missel, Harsh Prajapati +12
We study individual pulses of Vela (PSR\ B0833-45\,/\,J0835-4510) from daily observations of over three hours (around 120,000 pulses per observation), performed simultaneously with…
Nonthermal processes in hot accretion flows onto supermassive black holes: An inhomogeneous model
Eduardo M. Gutiérrez, Florencia L. Vieyro, Gustavo E. Romero
Context. Many low-redshift active galactic nuclei harbor a supermassive black hole accreting matter at low or medium rates. At such rates, the accretion flow usually consists of a…
PSR J0437-4715: The Argentine Institute of Radioastronomy 2019-2020 Observational Campaign
V. Sosa Fiscella, S. del Palacio, L. Combi +11
The Argentine Institute of Radio astronomy (IAR) is equipped with two single-dish 30-m radio antennas capable of performing daily observations of pulsars and radio transients in th…
The Origin of Matter at the Base of Relativistic Jets in Active Galactic Nuclei
Gustavo E. Romero, Eduardo M. Gutiérrez
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood. Relativistic jets are likely…
A nonthermal bomb explains the near-infrared superflare of Sgr A*
Eduardo M. Gutiérrez, Rodrigo Nemmen, Fabio Cafardo
The Galactic center supermassive black hole, Sgr A*, has experienced a strong, unprecedented flare in May 2019 when its near-infrared luminosity reached much brighter levels than e…
Primordial black hole evolution in two-fluid cosmology
Eduardo M. Gutiérrez, Florencia L. Vieyro, Gustavo E. Romero
Several processes in the early universe might lead to the formation of primordial black holes with different masses. These black holes would interact with the cosmic plasma through…
