Investigating the {Origin} of the Absorption-Line Variability in Narrow-Line Seyfert 1 Galaxy WPVS 007
Kaylie S. Green, Sarah C. Gallagher, Karen M. Leighly +5
Broad Absorption Line Quasars (BALQs) are actively accreting supermassive black holes that have strong outflows characterized by broad absorption lines in their rest-UV spectra. Va…
AMUSE-antlia I: Nuclear X-ray properties of early-type galaxies in a dynamically young galaxy cluster
Zhensong Hu, Yuanyuan Su, Zhiyuan Li +14
To understand the formation and growth of supermassive black holes (SMBHs) and their co-evolution with host galaxies, it is essential to know the impact of environment on the activ…
Collimation of the kiloparsec-scale radio jets in NGC 2663
Velibor Velović, M. D. Filipović, L. Barnes +25
We present the discovery of highly-collimated radio jets spanning a total of 355 kpc around the nearby elliptical galaxy NGC 2663, and the possible first detection of recollimation…
Host galaxy magnitude of OJ 287 from its colours at minimum light
Mauri J. Valtonen, Lankeswar Dey, S. Zola +54
OJ 287 is a BL Lacertae type quasar in which the active galactic nucleus (AGN) outshines the host galaxy by an order of magnitude. The only exception to this may be at minimum ligh…
The Eddington ratio-dependent changing look events in NGC 2992
Muryel Guolo, Daniel Ruschel-Dutra, Dirk Grupe +5
We present an analysis of historical multi-wavelength emission of the Changing Look (CL) Active Galactic Nucleus (AGN) in NGC 2992, covering epochs ranging from 1978 to 2021, as we…
Space Telescope and Optical Reverberation Mapping Project. XII. Broad-Line Region Modeling of NGC 5548
P. R. Williams, A. Pancoast, T. Treu +155
We present geometric and dynamical modeling of the broad line region for the multi-wavelength reverberation mapping campaign focused on NGC 5548 in 2014. The dataset includes photo…
