Exploring Galaxy Formation Models and Cosmologies with Galaxy Clustering
, 2012 Using N-body simulations and galaxy formation models, we study the galaxy stellar mass correlation and the two-point auto-correlation. The simulations are run with cosmological parameters from the WMAP first, third and seven year results, which mainly ...

The Epoch of Galaxy Formation [PDF]
Symposium - International Astronomical Union, 1978 Unfortunately, there is as yet no direct observation of a forming galaxy, nor of a manifestly “young” galaxy. It is not even clear what such galaxies might look like. There are, however, some lines of attack that will yield indirect information about the environment in which galaxies formed.

Galaxy Formation and Cluster Formation [PDF]
Symposium - International Astronomical Union, 1988 A primary motivation for studying globular clusters is that, as the oldest known galactic fossils, they trace the earliest stages of galactic evolution; indeed, they may hold the key to understanding galaxy formation. Thus it is clearly of great importance to learn how to read the fossil record. To do this, we need to understand something about how the

PAC. V. The Roles of Mass and Environment in the Quenching of Galaxies
The Astrophysical JournalThe roles that mass and environment play in galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs method, we analyze the excess surface distribution ${\bar{n}}_{2}{w}_{{\rm{p}}}({r}_{{\rm{p}}})$ of photometric ...

How Do Uncertainties in Galaxy Formation Physics Impact Field-level Galaxy Bias?
The Astrophysical JournalOur ability to extract cosmological information from galaxy surveys is limited by uncertainties in the galaxy–dark matter halo relationship for a given galaxy population, which are governed by the intricacies of galaxy formation.

Massive Neutrinos and Galaxy Formation
, 1994 We report the most recent results from high-resolution numerical simulations of structure formation in two flat cold+hot dark matter models with neutrino mass densities $\onu=0.2$ and 0.3. We find that structure forms too late in all CDM+HDM models with $

A LAW FOR STAR FORMATION IN GALAXIES [PDF]
The Astrophysical Journal, 2011 We study the galactic-scale triggering of star formation. We find that the largest mass-scale not stabilized by rotation, a well defined quantity in a rotating system and with clear dynamical meaning, strongly correlates with the star formation rate in a wide range of galaxies.

Galaxy Collisions, Gas Stripping and Star Formation in the Evolution of Galaxies
, 2004 A review of gravitational and hydrodynamical processes during formation of clusters and evolution of galaxies is given. Early, at the advent of N-body computer simulations, the importance of tidal fields in galaxy encounters has been recognized.
