Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole
Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185
The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…
Monitoring the Morphology of M87* in 2009-2017 with the Event Horizon Telescope
Maciek Wielgus, Kazunori Akiyama, Lindy Blackburn +26
The Event Horizon Telescope (EHT) has recently delivered the first resolved images of M87*, the supermassive black hole in the center of the M87 galaxy. These images were produced…
Observations of Four Nearby X-ray Faint AGN: Low Luminosity or Heavy Obscuration?
A. Annuar, D. M. Alexander, P. Gandhi +20
We present observations of four active galactic nuclei (AGN) located within 15 Mpc. These AGN, namely ESO 121-G6, NGC 660, NGC 3486 and NGC 5195, have observed X-ray lumin…
A broadband X-ray study of a sample of AGNs with [OIII] measured inclinations
X. Zhao, S. Marchesi, M. Ajello +2
In modeling the X-ray spectra of active galactic nuclei (AGNs), the inclination angle is a parameter that can play an important role in analyzing the X-ray spectra of AGN, but it h…
