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…
Boosting Lya and HeII 1640A Line Fluxes from Pop III Galaxies: Stochastic IMF Sampling and Departures from Case-B
Lluís Mas-Ribas, Mark Dijkstra, Jaime E. Forero-Romero
We revisit calculations of nebular hydrogen Lya and HeII 1640A line strengths for population III galaxies, undergoing continuous and bursts of star formation. We focus on initial m…
Impact of Cosmic Variance on the Galaxy-Halo Connection for Lyman- Emitters
Julian E. Mejia-Restrepo, Jaime E. Forero-Romero
In this paper we study the impact of cosmic variance and observational uncertainties in constraining the mass and occupation fraction, , of dark matter halos hosting L…
SPOKES: an End-to-End Simulation Facility for Spectroscopic Cosmological Surveys
B. Nord, A. Amara, A. Refregier +15
The nature of dark matter, dark energy and large-scale gravity pose some of the most pressing questions in cosmology today. These fundamental questions require highly precise measu…
