Tracing AGN Feedback Power with Cool/Warm Outflow Densities: Predictions and Observational Implications
Ivan Almeida, Tiago Costa, Chris M. Harrison +1
Winds launched at the scale of the accretion disc or dusty torus in Active Galactic Nuclei (AGN) are thought to drive energy-conserving outflows that shape galaxy evolution. The ke…
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…
Deep learning model for multiwavelength emission from low-luminosity active galactic nuclei
Ivan Almeida, Roberta Duarte, Rodrigo Nemmen
Most active supermassive black holes (SMBH) in present-day galaxies are underfed and consist of low-luminosity active galactic nuclei (LLAGN). They have multiwavelength broadband s…
The multiwavelength spectrum of NGC 3115: Hot accretion flow properties
Ivan Almeida, Rodrigo Nemmen, Ka-Wah Wong +2
NGC 3115 is the nearest galaxy hosting a billion solar mass black hole and is also a low-luminosity active galactic nucleus (LLAGN). X-ray observations of this LLAGN are able to sp…
