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…
The Diversity of Diffuse Ly Nebulae around Star-Forming Galaxies at High Redshift
Rui Xue, Kyoung-Soo Lee, Arjun Dey +6
We report the detection of diffuse Ly emission, or Ly halos (LAHs), around star-forming galaxies at and in the NOAO Deep Wide-Field Survey Boötes field.…
The DECam Minute Cadence Survey I
Claudia Belardi, Mukremin Kilic, Jeffrey A. Munn +4
We present the first results from a minute cadence survey of a three square degree field obtained with the Dark Energy Camera. We imaged part of the Canada-France-Hawaii Telescope…
Spectroscopic Confirmation of a Protocluster at z=3.786
Arjun Dey, Kyoung-Soo Lee, Naveen Reddy +5
We present new observations of the field containing the z=3.786 protocluster, PC217.96+32.3. We confirm that it is one of the largest and most overdense high-redshift structures kn…
The Network Behind the Cosmic Web
B. C. Coutinho, Sungryong Hong, Kim Albrecht +5
The concept of the cosmic web, viewing the Universe as a set of discrete galaxies held together by gravity, is deeply engrained in cosmology. Yet, little is known about the most ef…
