Accretion properties of low‐luminosity active galactic nuclei

Astronomische Nachrichten, 2021
AbstractWe aim to leverage the transformational science enabled by the Event Horizon Telescope (EHT) to study the physics of, and near, the black holes in a sample of galaxies covering a large parameter space in supermassive black hole mass, accretion rate, and jet power. To this end, we work on a sample of nearby galaxies whose directly measured black

Starbursts in Low Luminosity Active Galactic Nuclei

2005
Low Luminosity Active Galactic Nuclei (LLAGN), which comprise low-ionization nuclear emission-line regions (LINERs) and transition-type objects (TOs), represent the most common type of nuclear activity. Here, we search for spectroscopic signatures of starbursts and post-starbursts in LLAGN, and investigate their relationship to the ionization mechanism

Revealing Low Luminosity Active Galactic Nuclei (ReveaLLAGN)

2021
JWST will be the most sensitive tool ever built for studying the accretion onto supermassive black holes (SMBHs) at the centers of galaxies. While quasars and bright active galactic nuclei (AGN) provide spectacular examples of this accretion, a vast majority of galaxies have black holes accreting at much lower rates.

Ly  constraints on very low luminosity active galactic nuclei

Monthly Notices of the Royal Astronomical Society, 2006
Recent surveys have detected Lya emission from z = 4.5 to 6.5 at luminosities as low as 10 41 erg s -1 . There is good evidence that low numbers of active galactic nuclei (AGN) are among observed faint Lya emitters. Combining these observations with an empirical relation between the intrinsic Lya and B-band luminosities of AGN, we obtain an upper ...
