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…
Gravitational redshift and asymmetric redshift-space distortions for stacked clusters
Yan-Chuan Cai, Nick Kaiser, Shaun Cole +1
We derive the expression for the observed redshift in the weak field limit in the observer's past light cone, including all relativistic terms up to second order in velocity. We th…
The lensing and temperature imprints of voids on the Cosmic Microwave Background
Yan-Chuan Cai, Mark Neyrinck, Qingqing Mao +3
We have searched for the signature of cosmic voids in the CMB, in both the Planck temperature and lensing-convergence maps; voids should give decrements in both. We use zobov voids…
Testing the spherical evolution of cosmic voids
Vasiliy Demchenko, Yan-Chuan Cai, Catherine Heymans +1
We study the spherical evolution model for voids in CDM, where the evolution of voids is governed by dark energy at an earlier time than that for the whole universe or in overde…
Redshift-space distortions around voids
Yan-Chuan Cai, Andy Taylor, John A. Peacock +1
We have derived estimators for the linear growth rate of density fluctuations using the cross-correlation function of voids and haloes in redshift space, both directly and in Fouri…
