Are galaxies due to accretion?

Astronomische Nachrichten, 1985
AbstractBurnt‐out Population III remnants are thought to have acted as protogalactic seeds. Once tepid pancakes have formed such seeds (≈106 M⊙) could be subject to considerable growing by quasi‐stationary accretion.

Accretion Disks in the Centers of Galaxies

1988
We discuss the problems of α-accretion disks in soft potential wells of the centers of galaxies. If matter is fed into the disk only from large radii, accretion is very inefficient, as there is no shear that could drive it. If on the other hand matter falls into the disk at all radii, the disk may become so massive that it can change the potential, and

Galaxy as Dynamical System with Accreting Halo

1996
The dynamical evolution of the Galaxy system was analysed under the assumption that its Halo containes beside nonbaryonic matter some fraction of baryons in the form of “invisible” small hydrogen molecular clouds as was proposed by Pfenniger, Combes & Martinet (1994).

Dwarf Galaxy Accretion in the Milky Way: Viewing Dwarf Galaxy Accretion through the Eyes of Large Surveys

2020
Large spectroscopic and astrometric surveys, such as APOGEE and Gaia, provide us with large multi-dimensional data sets that allow us to study the Milky Way and its system of satellite dwarf galaxies in unprecedented detail. Among their many applications, these new tools afford us potent means by which to look for evidence of the accretion of dwarf ...
