The Intermediate-Mass Black Hole Reverberation Mapping Project: Scientific Overview and Sample Characteristics
Hengxiao Guo, Jiancheng Wu, Wenwen Zuo +38
Recent discoveries with the James Webb Space Telescope of massive black holes at high redshift have highlighted fundamental questions about black hole seed formation and the coevol…
Long-term optical spectral monitoring of a changing-look active galactic nucleus NGC 3516 -- II. Broad-line profile variability
Luka C. Popović, Dragana Ilić, Alexander Burenkov +10
We analyze the broad H line profile variability of the "changing look" active galactic nucleus (CL-AGN) NGC 3516 over a long period of 25 years. The observed change in the broad…
From Data to Software to Science with the Rubin Observatory LSST
Katelyn Breivik, Andrew J. Connolly, K. E. Saavik Ford +97
The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) dataset will dramatically alter our understanding of the Universe, from the origins of the Solar System to the…
The first supermassive black hole mass measurement in active galactic nuclei using the polarization of broad emission line Mg II
Đorđe Savić, Luka Č. Popović, Elena Shablovinskaya
Spectropolarimetric efforts in the last few years have provided an efficient method that is based on the profiles of the polarization plane position angle of broad emission lines i…
Spectroscopy and polarimetry of the gravitationally lensed quasar SDSS J1004+4112 with the 6m SAO RAS telescope
L. Č. Popović, V. L. Afanasiev, A. Moiseev +5
We present new spectroscopic and polarimetric observations of the gravitational lens SDSS J1004+4112 taken with the 6m telescope of the Special Astrophysical Observatory (SAO, Russ…
On the time delay evolution of five Active Galactic Nuclei
Andjelka Kovacevic, Luka C. Popovic, Alla I. Shapovalova +3
Here we investigate light curves of the continuum and emission lines of five type 1 active galactic nuclei (AGN) from our monitoring campaign, to test time-evolution of their time…
Flare-like variability of the Mg IIλ2800Å emission line in the gamma-ray blazar 3C 454.3
J. León-Tavares, V. Chavushyan, V. Patiño-Álvarez +9
We report the detection of a statistically significant flare-like event in the Mg IIλ2800Å emission line of 3C 454.3 during the outburst of autumn 2010. The highest levels of emiss…
The line parameters and ratios as the physical probe of the line emitting regions in AGN
D. Ilic, J. Kovacevic, L. C. Popovic
Here we discuss the physical conditions in the emission line regions (ELR) of active galactic nuclei (AGN), with the special emphasize on the unresolved problems, e.g. the stratifi…
