Is XRISM/Resolve probing a "raining" absorber in Mrk 509?
M. Dadina, V. Missaglia, V. Braito +19
X-ray spectroscopy of AGN offers unique insights into the reprocessing of radiationand gas dynamics near SMBH. The Sey 1 galaxy Mrk 509 is an ideal laboratory for these studies sin…
The X-ray Properties of Active Galactic Nuclei with Double-Peaked Balmer Lines
I. V. Strateva, W. N. Brandt, M. Eracleous +2
Double-peaked Balmer-line profiles originate in the accretion disks of a few percent of optically selected AGN. The reasons behind the strong low-ionization line emission from the…
Microlensing of the Fe K line and the X-ray continuum
L. C. Popovic, P. Jovanovic, E. Mediavilla +4
The observed enhancement of the Fe K line in three gravitationally lensed QSOs (MG J0414+0534, QSO 2237+0305, H1413+117) is interpreted in terms of microlensing, even when equi…
High-resolution X-ray spectroscopy of the Seyfert 2 galaxy Circinus with Chandra
R. M. Sambruna, H. Netzer, S. Kaspi +5
Results from a 60 ks Chandra HETGS observation of the nearby Seyfert 2 Circinus are presented. The spectrum shows a wealth of emission lines at both soft and hard X-rays, including…
X-raying winds in distant quasars: the first high-redshift wind duty cycle
E. Bertola, M. Dadina, M. Cappi +6
Theoretical models of wind-driven feedback from Active Galactic Nuclei (AGN) often identify Ultra-fast outflows (UFOs) as being the main cause for generating galaxy-size outflows,…
Caught in the Act; Chandra Observations of Microlensing of the Radio-Loud Quasar MG J0414+0534
G. Chartas, E. Agol, M. Eracleous +3
We present results from monitoring of the distant (z = 2.64), gravitationally lensed quasar MG J0414+0534 with the Chandra X-ray Observatory. An Fe Ka line at 6.49 +/- 0.09 keV (re…
