Absorption lines at high-redshift in front of quasars are quite
rare in the millimeter (mm) domain. Only five associated and five intervening systems have been reported in the literature up to 2023. These discoveries provide very useful information that is complementary to emission lines, allowing, for instance, to distinguish between inflows and outflows. These lines are also good candidates for studying the variations of the fundamental constants. I will describe recent findings with IRAM, ALMA, and MeerKAT. |
