The ambiguous AT2022rze: Changing-look AGN mimicking a supernova in a merging galaxy system

P. J. Pessi, R. Lunnan, J. Sollerman +36

AT2022rze is a luminous, ambiguous transient located South-East of the geometric center of its host galaxy at redshift z = 0.08. The host appears to be formed by a merging galaxy s…

Torus feeding and outflow launching in the active nucleus of the Circinus galaxy

Wout M. Goesaert, Konrad R. W. Tristram, C. M. Violette Impellizzeri +4

Context: Most active galactic nuclei (AGN) are believed to be surrounded by a dusty molecular torus on the parsec scale which is often embedded within a larger circumnuclear disk (…

I Zw 1 and H0557-385: The Dusty Tori of Two High Eddington AGNs Observed in the MATISSE LM-Bands

Farin Drewes, James H. Leftley, Sebastian F. Hönig +2

The torus in Active Galactic Nuclei (AGN) is a complex dynamical structure of gas and dust. It is thought to be composed of an equatorial dusty disk and a polar dusty wind launched…
