ASD Colloquium Series
|Decoding the cosmic evolution of star formation and black hole growth imprinted on the interstellar medium in galaxies
Special Location: B34, W120 A/B
The prominent peak in the history of star formation and black hole accretion at cosmic noon suggests strong evolution in the mechanisms that grow stars and black holes in galaxies over time. Infrared observations canquantify the energy balance between star formation and active galactic nuclei (AGN) activity, and constrain the composition and conditions of the gas and dust available to form new stars. In order to understand the enhanced activity at cosmic noon, wemeasure the interstellar medium (ISM) conditions in high redshift galaxies by combining diagnostics from mid-IR spectroscopy, far-IR/(sub)mm continuum and CO molecular lines. While ground-based facilities such as ALMA and the Large Millimeter Telescope (LMT) probe the cold ISM, JWST will be crucial for measuring the warm ISM and small dust grains. Looking to the future, a cold infrared telescope like the Origins Space Telescope is needed to decode the ISM conditions in all galaxies over cosmic time.
ASD Colloquia are Tuesdays at 3:45 pm (Meet the Speaker at 3:30 pm) in Bldg 34, Room W150 unless otherwise noted.
