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 the Atacama Large Millimeter Array (ALMA) and the Expanded Very Large Array (EVLA). The EVLA will be instrumental in detecting the radio continuum emission in these sources, whereas ALMA will map the dust continuum emission in sources out to the highest redshift. For the brightest sources, the EVLA can be used to also study the low-J rotational transitions of CO. 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 gas cooling lines of the interstellar medium. 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. The combination of EVLA and ALMA will thus enable a detailed characterization of objects at the earliest epochs.
