We present results from a spectroscopically blind search for associated and intervening HI 21-cm and OH 18-cm absorption lines towards 88 AGNs at $2\le z\le5$ using the upgraded Giant Metrewave Radio Telescope (uGMRT). The sample of AGNs with 1.4 GHz

The interstellar and circumnuclearmedium of active nuclei traced by HI21 cm absorption

Autor: Raffaella Morganti, Tom Oosterloo

Publikováno v: Astronomy and Astrophysics Review. 26

This review summarises what we have learnt in the last two decades based on HI 21-cm absorption observations about the cold interstellar medium (ISM) in the central regions of active galaxies and the interplay between this gas and the active nucleus

We present a detailed study of the quasar-galaxy pair: J1243+4043-UGC 07904. The sight line of the background quasar (z(q) = 1.5266) passes through a region of the galaxy (z(g) = 0.0169) at an impact parameter of 6.9 kpc with high metallicity (0.5 Z(
