Abstract

A substantial fraction of the Universe's star formation is heavily enshrouded by dust, and this basic fact has long been a hindrance to the development of a complete picture of galaxy evolution. Now, thanks to the advent of the Atacama Large Millimeter Array (ALMA) and the upgrades to the Karl G. Jansky Very Large Array (VLA), our view of dusty star formation at high-redshift is undergoing a radical transformation. I will present the latest results from COSMOS-XS, an ultra-deep VLA survey putting new constraints on the dust-unbiased star formation beyond the peak epoch of galaxy assembly. I will discuss what we have learned about the dustiest high-z galaxies thanks to ALMA, as well as imminent advances with James Webb Space Telescope (JWST). Finally, I will present new observations shedding insight into dust-obscured star formation in the epoch of reionization (z>6.5).
