Cosmological 3D H i Gas Map with HETDEX Lyα Emitters and eBOSS QSOs at z = 2: IGM−Galaxy/QSO Connection and a ∼40 Mpc Scale Giant H ii Bubble Candidate

Cosmological 3D H i Gas Map with HETDEX Lyα Emitters and eBOSS QSOs at z = 2: IGM−Galaxy/QSO Connection and a ∼40 Mpc Scale Giant H ii Bubble Candidate

We present cosmological ($30-400$ Mpc) distributions of neutral hydrogen (HI) in the inter-galactic medium (IGM) traced by Ly$\alpha$ Emitters (LAEs) and QSOs at $z=2.1-2.5$, selected with the data of the on-going Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) and the eBOSS survey. We investigate spatial correlations of LAEs and QSOs with …
