Monitoring AGNs with H Asymmetry. III. Long-term Reverberation Mapping Results of 15 Palomar-Green Quasars
Dong-Wei Bao, Michael S. Brotherton, Pu Du +42
In this third paper of the series reporting on the reverberation mapping (RM) campaign of active galactic nuclei with asymmetric H emission-line profiles, we present results for…
Discovery of a multiphase OVI and OVII absorber in the circumgalactic/intergalactic transition region
J. Ahoranta, A. Finoguenov, M. Bonamente +4
The observational constraints on the baryon content of the WHIM rely almost entirely on FUV measurements. However, cosmological, hydrodynamical simulations predict strong correlati…
Multi-Wavelength Monitoring and Reverberation Mapping of a Changing Look Event in the Seyfert Galaxy NGC 3516
V. L. Oknyansky, M. S. Brotherton, S. S. Tsygankov +26
We present the results of photometric and spectroscopic monitoring campaigns of the changing look AGN NGC 3516 carried out in 2018 to 2020 covering the wavelength range from the X-…
Hot WHIM counterparts of FUV OVI absorbers: Evidence in the line-of-sight towards quasar 3C 273
Jussi Ahoranta, Jukka Nevalainen, Nastasha Wijers +7
We explore the high spectral resolution X-ray data towards the quasar 3C273 to search for signals of hot ( K) X-ray-absorbing gas co-located with two established inte…
