Probing the photoionised outflow in the NLS1 Ark 564: An XMM-Newton view
Shourya Khanna, Jelle. S. Kaastra, Missagh Mehdipour
We present a detailed analysis of xmm X-ray observations of the Narrow line Seyfert-1 (NLS1) galaxy Ark 564 taken between 2000 and 2011. High-resolution X-ray spectroscopy is carri…
Flows of X-ray gas reveal the disruption of a star by a massive black hole
Jon M. Miller, Jelle S. Kaastra, M. Coleman Miller +18
Tidal forces close to massive black holes can violently disrupt stars that make a close approach. These extreme events are discovered via bright X-ray and optical/UV flares in gala…
A Soft X-Ray Spectral Episode for the Clocked Burster, GS 1826-24 as Measured by Swift and NuSTAR
J. Chenevez, D. K. Galloway, J. J. M. in 't Zand +12
We report on NuSTAR and Swift observations of a soft state of the neutron star low-mass X-ray binary GS 1826-24, commonly known as the "clocked" burster. The transition to the soft…
Anatomy of the AGN in NGC 5548: V. A clear view of the X-ray narrow emission lines
M. Whewell, G. Branduardi-Raymont, J. S. Kaastra +15
Context. Our consortium performed an extensive multi-wavelength campaign of the nearby Seyfert 1 galaxy NGC 5548 in 2013-14. The source appeared unusually heavily absorbed in the s…
Optical and X-ray early follow-up of ANTARES neutrino alerts
S. Adrian-Martinez, M. Ageron, A. Albert +137
High-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. Even with the recent detection of extr…
Line absorption of He-like triplet lines by Li-like ions. Caveats of using line ratios of triplets for plasma diagnostics
M. Mehdipour, J. S. Kaastra, A. J. J. Raassen
He-like ions produce distinctive series of triplet lines under various astrophysical conditions. However, this emission can be affected by line absorption from Li-like ions in the…
Anatomy of the AGN in NGC 5548: I. A global model for the broadband spectral energy distribution
M. Mehdipour, J. S. Kaastra, G. A. Kriss +24
An extensive multi-satellite campaign on NGC 5548 has revealed this archetypal Seyfert-1 galaxy to be in an exceptional state of persistent heavy absorption. Our observations taken…
ANTARES Constrains a Blazar Origin of Two IceCube PeV Neutrino Events
ANTARES Collaboration, S. Adrián-Martínez, A. Albert +166
The source(s) of the neutrino excess reported by the IceCube Collaboration is unknown. The TANAMI Collaboration recently reported on the multiwavelength emission of six bright, var…
