Massive black holes in galactic halos? (1985)
Journal Article
Lacey, C., & Ostriker, J. (1985). Massive black holes in galactic halos?. Astrophysical Journal, 299, 633-652. https://doi.org/10.1086/163729

The authors consider the idea that galaxy halos are composed of massive black holes as a possible resolution of two problems: the composition of dark halos, and the heating of stellar disks. It is found that in order to account for the amount of disk... Read More about Massive black holes in galactic halos?.

Chemical evolution of the galactic disk with radial gas flows (1985)
Journal Article
Lacey, C., & Fall, S. (1985). Chemical evolution of the galactic disk with radial gas flows. Astrophysical Journal, 290, 154-170. https://doi.org/10.1086/162970

Models are presented for the chemical evolution of the galactic disc with radial inflows of the gas at a velocity constant with time, but that may vary with the galactocentric radius. The models include the infall of metal-free gas from outside the d... Read More about Chemical evolution of the galactic disk with radial gas flows.
