The DESI Experiment Part II: Instrument Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectropic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations and the growth of structure through redshift…
The DESI Experiment Part I: Science,Targeting, and Survey Design
DESI Collaboration, Amir Aghamousa, Jessica Aguilar +290
DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy experiment that will study baryon acoustic oscillations (BAO) and the growth of structure through…
Impact of Baryonic Physics on Intrinsic Alignments
Ananth Tenneti, Nickolay Y. Gnedin, Yu Feng
We explore the effects of specific assumptions in the subgrid models of star formation and stellar and AGN feedback on intrinsic alignments of galaxies in cosmological simulations…
A fast algorithm for identifying Friends-of-Friends halos
Yu Feng, Chirag Modi
We describe a simple and fast algorithm for identifying friends-of-friends features and prove its correctness. The algorithm avoids unnecessary expensive neighbor queries, uses min…
The origin of most massive black holes at high-z: BLUETIDES and the next quasar frontier
Tiziana Di Matteo, Rupert A. C. Croft, Yu Feng +2
The growth of the most massive black holes in the early universe, consistent with the detection of highly luminous quasars at implies sustained, critical accretion of materi…
Forecasts for the WFIRST High Latitude Survey using the BlueTides Simulation
Dacen Waters, Tiziana Di Matteo, Yu Feng +2
We use the BlueTides simulation to predict the properties of the high- galaxy and active galactic nuclei (AGN) populations for the planned 2200deg Wide-Field Infrared Survey…
