High redshift quasars
We study the condition and impact of star-formation in galaxies at the cosmic epoch when galaxies assembled and most stars in the universe formed. Through observations of prominent molecular and atomic spectral lines, we unveil the detailed structures, dynamics and conditions of the interstellar medium of distant and super-average star-forming galaxies.
We also measure the star formation activity, gas content and distribution in representative samples of star-forming galaxies, using deep continuum interferometric observations. Looking ahead, we hope to use our novel sub-mm telescope CCAT-prime, exploiting its unique capability to study the impact of environment on the star-forming activity of high-redshift galaxies.
