The X-ray weakness of Little Red Dots and JWST-selected AGN: comparison with local AGN in different accretion regimes
A. Tortosa, C. Ricci, P. Du +5
We investigate the origin of the observed X-ray weakness in high z LRDs and other JWST-selected broad line AGN by comparing their X-ray and optical properties with those of a diver…
Long-term multiwavelength monitoring and reverberation mapping of NGC 2617 during a changing-look event
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +32
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC~2617 carried out from 2016 until 2022 and covering the wavelength range fr…
Changing-look active galactic nuclei: close binaries of supermassive black holes in action
Jian-Min Wang, Edi Bon
Changing-look active galactic nuclei (CL-AGNs) as a new subpopulation challenge some fundamental physics of AGNs because the timescales of the phenomenon can hardly be reconciled w…
The mass of the black hole in RE J1034+396
B. Czerny, B. You, A. Kurcz +6
The black hole mass measurement in active galaxies is a challenge, particularly in sources where the reverberation method cannot be applied. We aim to determine the black hole mass…
