Searching for Intermediate Mass Black Holes in galaxies with Low Luminosity AGN: A multiple-method approach
Filippos Koliopanos, Bogdan C. Ciambur, Alister W. Graham +7
Aims: This work is the first stage of a campaign to search for IMBHs, in low luminosity AGN (LLAGN) and dwarf galaxies. An additional, and equally important, aim of this pilot stud…
