Emergence of hot corona and truncated disk in simulations of accreting stellar mass black holes

Rodrigo Nemmen, Artur Vemado, Ivan Almeida +2

Stellar mass black holes in X-ray binaries (XRBs) are known to display different states characterized by different spectral and timing properties, understood in the framework of a…

Quenching star formation with low-luminosity AGN winds

Ivan Almeida, Rodrigo Nemmen, Rogemar A. Riffel

We present a simple model for low-luminosity active galactic nucleus (LLAGN) feedback through winds produced by a hot accretion flow. The wind carries considerable energy and depos…
