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…
Reverberation Mapping of Optical Emission Lines in Five Active Galaxies
M. M. Fausnaugh, C. J. Grier, M. C. Bentz +68
We present the first results from an optical reverberation mapping campaign executed in 2014, targeting the active galactic nuclei (AGN) MCG+08-11-011, NGC 2617, NGC 4051, 3C 382,…
A 14 Gpc study of cosmic homogeneity using BOSS DR12 quasar sample
Pierre Laurent, Jean-Marc Le Goff, Etienne Burtin +16
The BOSS quasar sample is used to study cosmic homogeneity with a 3D survey in the redshift range . We measure the count-in-sphere, , i.e. the average number o…
A Constraint on Quasar Clustering at z=5 from a Binary Quasar
Ian McGreer, Sarah Eftekharzadeh, Adam Myers +1
We report the discovery of a quasar pair at z=5 separated by 21 arcsec. Both objects were identified as quasar candidates using simple color selection techniques applied to photome…
