Abstract: | Detecting and studying objects at the highest redshifts, out to the end of Cosmic Reionization at z>7, is clearly a key science goal of ALMA. ALMA will in principle be able to detect objects in this redshift range both from
high-J (J>7) CO transitions and emission from ionized carbon, CII], which is one of the main cooling lines of the ISM. ALMA will even
be able to resolve this emission for individual targets, which will be one of the few ways to determine dynamical masses for
systems in the Epoch of Reionization. We discuss some of the current problems regarding the detection and characterization
of objects at high redshifts and how ALMA will eliminate most (but not all) of them. |
