Formation of disk galaxies in preheated media: a preventative feedback model
Yu Lu, H. J. Mo, Risa H. Wechsler
We introduce a semi-analytic galaxy formation model implementing a self-consistent treatment for the hot halo gas configuration and the assembly of central disks. Using the model,…
A Comparison between Semi-Analytic Model Predictions for the CANDELS Survey
Yu Lu, Risa H. Wechsler, Rachel S. Somerville +13
We compare the predictions of three independently developed semi-analytic galaxy formation models that are being used to aid in the interpretation of results from the CANDELS surve…
Bayesian inferences of galaxy formation from the K-band luminosity and HI mass functions of galaxies: constraining star formation and feedback
Yu Lu, H. J. Mo, Zhankui Lu +2
We infer mechanisms of galaxy formation for a broad family of semi-analytic models (SAMs) constrained by the K-band luminosity function and HI mass function of local galaxies using…
Mergers and Mass Accretion for Infalling Halos Both End Well Outside Cluster Virial Radii
Peter S. Behroozi, Risa H. Wechsler, Yu Lu +4
We find that infalling dark matter halos (i.e., the progenitors of satellite halos) begin losing mass well outside the virial radius of their eventual host halos. The peak mass occ…
Cosmological Constraints from Galaxy Clustering and the Mass-to-Number Ratio of Galaxy Clusters: Marginalizing over the Physics of Galaxy Formation
Rachel Reddick, Jeremy Tinker, Risa Wechsler +1
Many approaches to obtaining cosmological constraints rely on the connection between galaxies and dark matter. However, the distribution of galaxies is dependent on their formation…
An Empirical Model for the Star Formation History in Dark Matter Halos
Zhankui Lu, Houjun Mo, Yu Lu +4
We develop an empirical approach to infer the star formation rate in dark matter halos from the galaxy stellar mass function (SMF) at different redshifts and the local cluster gala…
