The WISSH Quasars Project III. X-ray properties of hyper-luminous quasars
S. Martocchia, E. Piconcelli, L. Zappacosta +14
We perform a survey of the X-ray properties of 41 objects from the WISE/SDSS selected Hyper-luminous (WISSH) quasars sample, composed by 86 broad-line quasars (QSOs) with bolometri…
An X-ray view of Mrk 705: A borderline narrow-line Seyfert 1 galaxy
L. C. Gallo, I. Balestra, E. Costantini +4
Mrk 705 exhibits optical properties of both narrow- and broad-line Seyfert 1 galaxies. We examine the X-ray properties of this borderline object utilising proprietary and public da…
The Spectral Energy Distribution and Emission-Line properties of the NLS1 Galaxy Arakelian 564
P. Romano, S. Mathur, T. J. Turner +11
We present the intrinsic spectral energy distribution (SED) of the NLS1 Arakelian 564, constructed with contemporaneous data obtained during a multi-wavelength, multi-satellite obs…
A 12-day ASCA Observation of the Narrow-Line Seyfert 1 Galaxy Ton S180: Time-Selected Spectroscopy
P. Romano, T. J. Turner, S. Mathur +1
We present an analysis of the X-ray variability properties of the NLS1 galaxy Ton S180, based upon a 12-day continuous ASCA observation. We observe flux variations of a factor of 3…
The Chandra X-ray Observatory Resolves the X-ray Morphology and Spectra of a Jet in PKS 0637-752
G. Chartas, D. M. Worrall, M. Birkinshaw +14
The core-dominated radio-loud quasar PKS 0637-752 (z = 0.654) was the first celestial object observed with the Chandra X-ray Observatory, offering the early surprise of the detecti…
