## Dust & Gas in High-z QSOs - PhD Thesis

Beelen, A.

This thesis presents the study of dust and gas in high redshift quasars (QSOs) based on (sub)millimeter and radio observations. The surveys of the infrared and radio continuum of optically luminous and radio-quiet QSOs at $$1.9 < z < 6.4$$ indicate the presence of large dust masses …
