Toward explaining Seyfert galaxies

open access: yesThe Astrophysical Journal, 1983
Galaxies with extensive star formation in their nuclei (star-burst galaxies) produce up to 10/sup 9/ M/sub sun/ of compact stellar remnants in their nuclei. Data for the kinematics of these remnants imply that a significant fraction can settle into nuclear volumes of radii 1 pc.
