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…
