TLDR
In this paper, it was shown that if all protospirals contain subgalactic clouds with a similar mass spectrum, the specific frequency of globular clusters around spirals will be constant.Abstract:
We suggest that at least some globular clusters are formed during the interaction or merger of galaxies. Such events could explain the disk population of clusters in the Galaxy, the young globulars in the Magellanic Clouds, the excess of clusters around ellipticals relative to spirals of the same luminosity and the anomalously large globular cluster systems around some galaxies in the center of galaxy clusters. We show that if all protospirals contain subgalactic clouds with a similar mass spectrum, the specific frequency of globular clusters around spirals will be constantread more

Coevolution (Or Not) of Supermassive Black Holes and Host Galaxies
John Kormendy,Luis C. Ho +1 more
TL;DR: In this paper, supermassive black holes (BHs) have been found in 85 galaxies by dynamical modeling of spatially resolved kinematics, and it has been shown that BHs and bulges coevolve by regulating each other's growth.

Coevolution (Or Not) of Supermassive Black Holes and Host Galaxies: Supplemental Material
John Kormendy,Luis C. Ho +1 more
TL;DR: Kormendy and Ho as mentioned in this paper proposed a method to estimate the BH masses for galaxies with active nuclei (AGNs) based on the observational criteria that are used to classify classical and pseudo bulges.

The New Galaxy: Signatures of Its Formation
TL;DR: The formation and evolution of galaxies is one of the great outstanding problems of astrophysics as discussed by the authors, and a detailed physical picture where individual stellar populations can be associated with (tagged to) elements of the protocloud is far beyond our current understanding.

Extragalactic Globular Clusters and Galaxy Formation
Jean P. Brodie,Jay Strader +1 more
TL;DR: In this article, it was shown that metal-poor GCs formed in low-mass dark matter halos in the early universe and that their properties reflect biased galaxy assembly, while metal-rich GCs were born in the subsequent dissipational buildup of their parent galaxies.

A Universal Formation Mechanism for Open and Globular Clusters in Turbulent Gas
TL;DR: In this article, a universal mechanism for cluster formation in all epochs and environments is found to be consistent with the properties and locations of young and old globular clusters, open clusters and unbound associations, and interstellar clouds.
