On the galaxy-halo connection in the EAGLE simulation
Harry Desmond, Yao-Yuan Mao, Risa Wechsler +2
Empirical models of galaxy formation require assumptions about the correlations between galaxy and halo properties. These may be calibrated against observations or inferred from ph…
Forward Modeling of Large-Scale Structure: An open-source approach with Halotools
Andrew Hearin, Duncan Campbell, Erik Tollerud +11
We present the first stable release of Halotools (v0.2), a community-driven Python package designed to build and test models of the galaxy-halo connection. Halotools provides a mod…
The connection between the host halo and the satellite galaxies of the Milky Way
Yu Lu, Andrew Benson, Yao-Yuan Mao +5
Many properties of the Milky Way's dark matter halo, including its mass assembly history, concentration, and subhalo population, remain poorly constrained. We explore the connectio…
Sussing Merger Trees: Stability and Convergence
Yang Wang, Frazer R. Pearce, Alexander Knebe +15
Merger trees are routinely used to follow the growth and merging history of dark matter haloes and subhaloes in simulations of cosmic structure formation. Srisawat et al. (2013) co…
The Eating Habits of Milky Way Mass Halos: Destroyed Dwarf Satellites and the Metallicity Distribution of Accreted Stars
Alis J. Deason, Yao-Yuan Mao, Risa H. Wechsler
We study the mass spectrum of destroyed dwarfs that contribute to the accreted stellar mass of Milky Way (MW) mass M_vir ~ 10^12.1 M_sun) halos using a suite of 45 zoom-in, dissipa…
Detection of lensing substructure using ALMA observations of the dusty galaxy SDP.81
Yashar D. Hezaveh, Neal Dalal, Daniel P. Marrone +13
We study the abundance of substructure in the matter density near galaxies using ALMA Science Verification observations of the strong lensing system SDP.81. We present a method to…
