A Window on Cosmic Evolution through ALMA Calibrator Data
Year: 2024
Type: article
Abstract: The ALMACAL survey, a comprehensive study of ALMA calibrator data, has been pivotal in advancing our scientific understanding in many areas. This talk will review the major milestones achieved, with a particular focus on the molecular gas evolution traceable by CO emission within the calibrator fields. I will present new results of the blind CO search using all available calibrator data until May 2022 in Band 3 and 6, accumulating about 540 hours. The upcoming ALMA Wideband Sensitivity upgrade, promising a fourfold increase in bandwidth, will significantly enhance the frequency coverage of each calibrator data set. I will discuss the impact of these upgrades on the ALMACAL survey in terms of the improved emission-line sensitivity and much increased line search efficiency of ALMA, which will revolutionize our understanding of the cosmic evolution of cold gas.
