Constraining Scatter in the Stellar Mass--Halo Mass Relation for Haloes Less Massive than the Milky Way
Magdelena Allen, Peter Behroozi, Chung-Pei Ma
Most galaxies are hosted by massive, invisible dark matter haloes, yet little is known about the scatter in the stellar mass--halo mass relation for galaxies with host halo masses…
Weak Lensing Reveals a Tight Connection Between Dark Matter Halo Mass and the Distribution of Stellar Mass in Massive Galaxies
Song Huang, Alexie Leauthaud, Andrew Hearin +9
Using deep images from the Hyper Suprime-Cam (HSC) survey and taking advantage of its unprecedented weak lensing capabilities, we reveal a remarkably tight connection between the s…
Emission line ratios for the Circumgalactic Medium and the "Bimodal" Nature of Galaxies
Huanian Zhang, Dennis Zaritsky, Jessica Werk +1
We find significantly different diagnostic emission line ratios for the circumgalactic gas associated with galaxies of stellar masses above and below M using SD…
Reliable Determination of Contact Angle from the Height and Volume of Sessile Drops
Feredoon Behroozi, Peter Behroozi
Contact angle is an important parameter in characterizing the wetting properties of fluids. The most common methods for measuring the contact angle is to measure it directly from t…
UniverseMachine: The Correlation between Galaxy Growth and Dark Matter Halo Assembly from z=0-10
Peter Behroozi, Risa Wechsler, Andrew Hearin +1
We present a method to flexibly and self-consistently determine individual galaxies' star formation rates (SFRs) from their host haloes' potential well depths, assembly histories,…
Emission from the Ionized Gaseous Halos of Low Redshift Galaxies and Their Neighbors
Huanian Zhang, Dennis Zaritsky, Peter Behroozi
Using a sample of nearly half a million galaxies, intersected by over 8 million lines of sight from the Sloan Digital Sky Survey Data Release 12, we extend our previous study of th…
