A deep X-ray view of the bare AGN Ark120. IV. XMM-Newton and NuSTAR spectra dominated by two temperature (warm, hot) Comptonization processes
D. Porquet, J. N. Reeves, G. Matt +16
We perform an X-ray spectral analysis of the brightest and cleanest bare AGN known so far, Ark 120, in order to determine the process(es) at work in the vicinity of the SMBH. We pr…
A Hard X-ray Study of the Normal Star-Forming Galaxy M83 with NuSTAR
M. Yukita, A. E. Hornschemeier, B. D. Lehmer +19
We present results from sensitive, multi-epoch NuSTAR observations of the late-type star-forming galaxy M83 (d=4.6 Mpc), which is the first investigation to spatially resolve the h…
NuSTAR reveals the extreme properties of the super-Eddington accreting SMBH in PG 1247+267
G. Lanzuisi, M. Perna, A. Comastri +26
PG1247+267 is one of the most luminous known quasars at and is a strongly super-Eddington accreting SMBH candidate. We obtained NuSTAR data of this intriguing source in De…
NuSTAR and Swift observations of the very high state in GX 339-4: Weighing the black hole with X-rays
M. L. Parker, J. A. Tomsick, J. A. Kennea +14
We present results from spectral fitting of the very high state of GX~339-4 with NuSTAR and Swift. We use relativistic reflection modelling to measure the spin of the black hole an…
The rhythm of Fairall 9 -- I: Observing the spectral variability with XMM-Newton and NuSTAR
Anne Lohfink, Christopher Reynolds, Ciro Pinto +13
We present a multi-epoch X-ray spectral analysis of the Seyfert 1 galaxy Fairall 9. Our analysis shows that Fairall 9 displays unique spectral variability in that its ratio residua…
Rapid Variability of Blazar 3C 279 during Flaring States in 2013-2014 with Joint Fermi-LAT, NuSTAR, Swift, and Ground-Based Multi-wavelength Observations
M. Hayashida, K. Nalewajko, G. M. Madejski +49
We report the results of a multi-band observing campaign on the famous blazar 3C 279 conducted during a phase of increased activity from 2013 December to 2014 April, including firs…
