A Hybrid R-Theta Fiber Positioning Robot Using a Piezoelectric Bender for Radial Motion
Michael Schubnell, Tim Fanning, Andrew Hope +3
Future massively multiplexed spectroscopic surveys require focal planes with increasingly dense arrays of robotic fiber positioners. The DESI (Dark Energy Spectroscopic Instrument)…
Spec-S5: A Next-Generation All-Sky Spectroscopic Facility Enabling Large-Scale Surveys for Cosmology and Astrophysics
Claire Poppett, David J. Schlegel, Arjun Dey +8
The Stage-5 Spectroscopic Experiment (Spec-S5) is a next-generation, all-sky spectroscopic facility designed to address fundamental questions in cosmology and astrophysics. Buildin…
Luminosity function of quasars at from SDSS and DESI
Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54
We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
Cosmic Pairs: A DESI Census of Dual and Offset AGN as Precursors to Massive Black Hole Binaries
Ekaterine Dadiani, Antonella Palmese, Yihao Zhou +52
The paper presents a large, uniformly selected spectroscopic catalog of dual and offset active galactic nuclei from the first DESI data release, analyzing their host galaxy propert…
Linear motion (R-FLEX) for minature 6.2 mm pitch optical fiber position robots with polar (R-theta) kinematics
Nicholas R. Wenner, Joseph H. Silber, Michael S. Schubnell +4
The paper presents R‑FLEX, a compact flexure‑based radial positioning mechanism that converts small base rotations into precise, low‑backlash linear motion for densely packed fiber…
ODIN: Characterizing the Three-dimensional Structure of Two Protocluster Complexes at
Vandana Ramakrishnan, Ashley Ortiz, Byeongha Moon +52
We present a detailed study of the 3D morphology of two extended associations of multiple protoclusters at . These protocluster 'complexes', designated COSMOS-z3.1-A and COS…
