Probing the gas, dust and stars in galaxies at cosmic noon and beyond

Jacqueline Hodge

Probing the gas, dust, and dust-obscured stars in galaxies at cosmic noon and beyond is critical for a complete understanding of galaxy evolution. To this end, huge strides have been made recently thanks to the Atacama Large Millimeter Array (ALMA), the Karl G. Jansky Very Large Array (VLA), and now the James Webb Space Telescope (JWST). I will present recent results from our ongoing VLA Legacy Survey of Molecular Gas at High Redshift (AS2VLA), including insights into the large variety of cold gas properties of z>2 galaxies via CO(1-0) and [CI] emission line studies. I will then present a joint ALMA+JWST imaging study of the dust continuum and stellar emission in 13 z>2 galaxies, including the finding that the dust structure on ∼kpc-scales is broadly similar to that in nearby galaxies. Finally, I will discuss our efforts to extend these studies to galaxies within the Universe's first billion years (z>6).
