Observational Constraints on Sunyaev–Zeldovich Effect Halos around High-z Quasars

Observational Constraints on Sunyaev–Zeldovich Effect Halos around High-z Quasars

We present continuum observations from the Atacama Large Millimeter/submillimeter Array of 10 high-redshift (2.2 ≤ z ≤ 2.7) ultraluminous quasars (QSOs) and constrain the presence of hot, ionized, circumgalactic gas in a stacking analysis. We measure a Compton- y parameter profile with a peak value...
