Relativistic spectroscopy of the extreme NLS1 IRAS13224-3809
M. L. Parker, W. N. Alston, D. J. K Buisson +5
The narrow line Seyfert 1 (NLS1) IRAS 13224-3809 is the most X-ray variable active galactic nucleus (AGN), exhibiting 0.3-10 keV flux changes of over an order of magnitude within a…
AGN feedback in the Phoenix cluster
Ciro Pinto, Christopher J. Bambic, Jeremy S. Sanders +5
Active galactic nuclei (AGN) release a huge amount of energy into the intracluster medium (ICM) with the consequence of offsetting cooling and star formation (AGN feedback) in the…
NuSTAR observations of Mrk 766: distinguishing reflection from absorption
D. J. K. Buisson, M. L. Parker, E. Kara +14
We present two new NuSTAR observations of the narrow line Seyfert 1 (NLS1) galaxy Mrk 766 and give constraints on the two scenarios previously proposed to explain its spectrum and…
Constraints on the Chemical Enrichment History of the Perseus Cluster of Galaxies from High-Resolution X-ray Spectroscopy
A. Simionescu, S. Nakashima, H. Yamaguchi +32
High-resolution spectroscopy of the core of the Perseus Cluster of galaxies, using the satellite above 2 keV and the - Reflection Grating Spectrometer at lowe…
A high-density relativistic reflection origin for the soft and hard X-ray excess emission from Mrk 1044
Labani Mallick, William N. Alston, Michael L. Parker +7
We present the first results from a detailed spectral-timing analysis of a long (130 ks) XMM-Newton observation and quasi-simultaneous NuSTAR and Swift observations of the hi…
The remarkable X-ray variability of IRAS 13224-3809 I: The variability process
W. N. Alston, A. C. Fabian, D. J. K. Buisson +17
We present a detailed X-ray timing analysis of the highly variable NLS1 galaxy, IRAS 13224-3809. The source was recently monitored for 1.5 Ms with XMM-Newton which, combined with 5…
