The Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) Survey Design, Reductions, and Detections

Karl Gebhardt, Erin Mentuch Cooper, Robin Ciardullo +60

We describe the survey design, calibration, commissioning, and emission-line detection algorithms for the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). The goal of HETDEX…

SILVERRUSH. XI. Intensity Mapping for Lya Emission Extending over $100 - 1000$ comoving kpc around $z \sim 2 - 7$ LAEs with Subaru HSC-SSP and CHORUS Data

Shotaro Kikuchihara, Yuichi Harikane, Masami Ouchi +14

We conduct intensity mapping to probe for extended diffuse Ly $α$ emission around Ly $α$ emitters (LAEs) at $z \sim 2 - 7$ , exploiting very deep ( $\sim 26$ mag at $5 σ$ ) and large-area ($\…

First HETDEX Spectroscopic Determinations of Ly $α$ and UV Luminosity Functions at $z = 2 - 3$ : Bridging a Gap Between Faint AGN and Bright Galaxies

Yechi Zhang, Masami Ouchi, Karl Gebhardt +21

We present Ly $α$ and ultraviolet-continuum (UV) luminosity functions (LFs) of galaxies and active galactic nuclei (AGN) at $z = 2.0 - 3.5$ determined by the un-targetted optical spectr…

SILVERRUSH. IX. Lya Intensity Mapping with Star-Forming Galaxies at z=5.7 and 6.6: A Possible Detection of Extended Lya Emission at $≳$ 100 comoving kpc around and beyond the Virial-Radius Scale of Galaxy Dark Matter Halos

Ryota Kakuma, Masami Ouchi, Yuichi Harikane +11

We present results of the cross-correlation Ly $α$ intensity mapping with Subaru/Hyper Suprime-Cam (HSC) ultra-deep narrowband images and Ly $α$ emitters (LAEs) at $z = 5.7$ and $6.6$ …
