Photoionized emission and absorption features in the high-resolution X-ray spectra of NGC 3783
Junjie Mao, M. Mehdipour, J. S. Kaastra +14
Our Swift monitoring program triggered two joint XMM-Newton, NuSTAR and HST observations on 11 and 21 December 2016 targeting NGC 3783, as its soft X-ray continuum was heavily obsc…
Recurring obscuration in NGC 3783
J. S. Kaastra, M. Mehdipour, E. Behar +14
Obscuration of the continuum emission from active galactic nuclei by streams of gas with relatively high velocity (> 1000 km/s) and column density (>3E25 per m2) has been seen in a…
Multi-wavelength campaign on NGC 7469: III. Spectral energy distribution and the AGN wind photoionisation modelling, plus detection of diffuse X-rays from the starburst with Chandra HETGS
M. Mehdipour, J. S. Kaastra, E. Costantini +15
We investigate the physical structure of the AGN wind in the Seyfert-1 galaxy NGC 7469 through high-resolution X-ray spectroscopy with Chandra HETGS and photoionisation modelling.…
Multi-wavelength campaign on NGC 7469 IV. The broad-band X-ray spectrum
R. Middei, S. Bianchi, M. Cappi +17
We conducted a multi-wavelength six-month campaign to observe the Seyfert galaxy NGC~7469, using the space-based observatories \textit{HST}, \textit{Swift}, \textit{XMM-Newton} and…
Characterization of the Infrared/X-ray sub-second variability for the black-hole transient GX 339-4
F. M. Vincentelli, P. Casella, T. J. Maccarone +7
We present a detailed analysis of the X-ray/IR fast variability of the Black-Hole Transient GX 339-4 during its low/hard state in August 2008. Thanks to simultaneous high time-reso…
Yet another UFO in the X-ray spectrum of a high-z lensed QSO
M. Dadina, C. Vignali, M. Cappi +6
Ultra-fast outflows (UFO) appear to be common in local active galactic nuclei (AGN) and may be powerful enough (1\% of L) to effectively quench the sta…
