Observation of A Solar Like Magnetic Reconnection Event in an AGN Corona with XRISM
Gal Vardi, Ehud Behar, Liyi Gu +14
The X-ray source in AGN is commonly referred to as the corona by analogy to stellar coronae. The similarities between the two suggest that the heating mechanism of AGN coronae is m…
On the transformation of the Maxwell-Boltzmann Distribution to a Power-Law
Ari Laor, Igor Gitelman
Power-law (PL) distribution functions (DF) are prevalent in highly diverse systems. The systems range in size from nanometer to mega light years, in complexity from dust grains to…
The CLASS Quasar Catalog: Coronal Line Activity in Type 1 SDSS Quasars
Sara Doan, Shobita Satyapal, Michael Reefe +7
We conduct the first systematic survey of a total of eleven optical coronal lines in the spectra of a large sample of low redshift (z < 0.8) Type 1 quasars observed by the Sloan Di…
Why are optical coronal lines faint in active galactic nuclei?
Jeffrey D. McKaig, Shobita Satyapal, Ari Laor +4
Forbidden collisionally excited optical atomic transitions from high ionization potential (IP54.8\,eV) ions, such as Ca, Ne, Fe$^{\mathrm{6+}}…
Parsec-Scale Localization of the Quasar SDSS J1536+0441A, a Candidate Binary Black Hole System
J. M. Wrobel, A. Laor
The radio-quiet quasar SDSS J1536+0441A shows two broad-line emission systems, recently interpreted as a binary black hole (BBH) system with a subparsec separation; as a double-pea…
An exploratory study of the hard X-ray variability properties of PG quasars with RXTE
M. Guainazzi, F. Fiore, E. Giallongo +3
We have monitored with the RXTE PCA the variability pattern of the 2-20 keV flux in four PG quasars (QSOs) from the Laor et al. (1994) sample. Six observations of each target at re…
