We present results from a joint XMM–Newton/NuSTAR monitoring of the Seyfert 1 NGC 4593, consisting of 5 × 20 ks simultaneous observations spaced by 2 d, performed in 2015 January. The source is variable, both in flux and spectral shape, on time-scales down to a few ks and with a clear softer-when-brighter behaviour. In agreement with past observations, we find the presence of a warm absorber well described by a two-phase ionized outflow. The source exhibits a cold, narrow and constant Fe K… Expand
Radio/X-ray monitoring of the broad-line radio galaxy 3C 382. High-energy view with XMM-Newton and NuSTAR
We present the analysis of five joint XMM–Newton/NuSTARobservations, 20 ks each and separated by 12 days, of the broad-line radio galaxy 3C 382. The data were obtained as part of a campaign performedExpand
High-energy monitoring of NGC 4593 II. Broad-band spectral analysis: testing the two-corona model
It is widely believed that the primary X-ray emission of AGN is due to the Comptonization of optical-UV photons from a hot electron corona, while the origin of the ‘soft-excess’ is still uncertainExpand
NuSTAR Uncovers an Extremely Local Compton-thick AGN in NGC 4968
We present the analysis of Chandra and NuSTAR spectra of NGC 4968, a local (D$\sim$44 Mpc) 12$\mu$m-selected Seyfert 2 galaxy, enshrouded within Compton-thick layers of obscuring gas. We find noExpand
Correlated X-ray/UV/optical emission and short-term variability in a Seyfert 1 galaxy NGC 4593
We present a detailed multi-frequency analysis of an intense monitoring programme of Seyfert 1 galaxy NGC 4593 over a duration of nearly for a month with Swift observatory. We used 185 pointings toExpand
Study of X-ray variability and coronae of Seyfert galaxies using NuSTAR
The primary X-ray emission in active galactic nuclei (AGN) originates in a compact region called the corona located very close to the super-massive black hole and the accretion disk. The knowledge ofExpand
Tracking the iron K α line and the ultra fast outflow in NGC 2992 at different accretion states
The Seyfert 2 galaxy NGC 2992 has been monitored eight times by XMM-Newton in 2010 and then observed again in 2013, while in 2015 it was simultaneously targeted by Swift and NuSTAR. XMM-Newton alwaysExpand
Properties of AGN coronae in the NuSTAR era – II. Hybrid plasma
The corona, a hot cloud of electrons close to the centre of the accretion disc, produces the hard X-ray power-law continuum commonly seen in luminous Active Galactic Nuclei (AGN). The continuum has aExpand
A deep X-ray view of the bare AGN Ark 120: IV. XMM-Newton and NuSTAR spectra dominated by two temperature (warm, hot) Comptonization processes
Context. The physical characteristics of the material closest to supermassive black holes (SMBHs) are primarily studied through X-ray observations. However, the origins of the main X-ray componentsExpand
EUCLIA. II. On the Puzzling Large UV to X-Ray Lags in Seyfert Galaxies
Recent intense X-ray and UV monitoring campaigns with Swift have detected clear UV lags behind X-ray in several local active galactic nuclei (AGNs). The UV to X-ray lags are often larger (by a factorExpand
Quasar spectral variability from the XMM-Newton serendipitous source catalogue
Context. X-ray spectral variability analyses of Active Galactic Nuclei (AGN) with moderate luminosities and redshifts typically show a softer when brighter behaviour. Such trend has been rarelyExpand
