THE ALPINE-ALMA [C II] SURVEY. MOLECULAR GAS BUDGET IN THE EARLY UNIVERSE AS TRACED BY [C II]

Redazione
(AGENPARL) – GARCHING (GERMANY), mar 24 novembre 2020 First Author: Dessauges-Zavadsky, M.Instruments: ALMA_Band_7, ALMA_BandsProgramIDs: 2017.1.00428.LBibCode: 2020A&A…643A…5D The molecular gas content of normal galaxies at z > 4 is poorly constrained because the commonly used molecular gas tracers become hard to detect at these high redshifts. We use the [C II]......
