Observational Evidence for Large-scale Gas Heating in a Galaxy Protocluster at z = 2.30

Observational Evidence for Large-scale Gas Heating in a Galaxy Protocluster at z = 2.30

We report a z = 2.30 galaxy protocluster (COSTCO-I) in the COSMOS field, where the Ly α forest as seen in the CLAMATO IGM tomography survey does not show significant absorption. This departs from the transmission–density relationship (often dubbed the fluctuating Gunn–Peterson approximation; FGPA) u...
