Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA

Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Zhaoxuan Liu, Manda Banerji, Tomoko Suzuki | Summary: We present a study of the molecular gas in five closely-spaced ($R_{perp}<20$ kpc) dual quasars ($L_{rm bol}gtrsim10^{44}~mathrm{erg~s}^{-1}$) at redshifts $0.4<z<0.8$ with the Atacama Large Millimeter/submillimeter Array. The dual quasar phase represents a distinctive […]
