High-resolution X-ray spectroscopy: the coming-of-age

J. S. Kaastra

Since the launch of Chandra and XMM-Newton, high-resolution X-ray spectra of cosmic sources of all kinds have become available. These spectra have resulted in major scientific brea…

Disk-Wind Connection During the Heartbeats of GRS 1915+105

Abderahmen Zoghbi, J. M. Miller, A. L. King +14

Disk and wind signatures are seen in the soft state of Galactic black holes, while the jet is seen in the hard state. Here we study the disk-wind connection in the class of var…

Systematic comparison of photoionised plasma codes with application to spectroscopic studies of AGN in X-rays

M. Mehdipour, J. S. Kaastra, T. Kallman

Atomic data and plasma models play a crucial role in the diagnosis and interpretation of astrophysical spectra, thus influencing our understanding of the universe. In this investig…

Anatomy of the AGN in NGC 5548 VIII. XMM-Newton's EPIC detailed view of an unexpected variable multilayer absorber

M. Cappi, B. De Marco, G. Ponti +21

In 2013 we conducted a large multi-wavelength campaign on the archetypical Seyfert 1 galaxy NGC 5548. Unexpectedly, this usually unobscured source appeared strongly absorbed in the…

Murchison Widefield Array Limits on Radio Emission from ANTARES Neutrino Events

S. Croft, D. L. Kaplan, S. J. Tingay +131

We present a search, using the Murchison Widefield Array (MWA), for electromagnetic counterparts to two candidate high energy neutrino events detected by the ANTARES neutrino teles…

The Accretion Disk Wind in the Black Hole GRS 1915+105

J. M. Miller, J. Raymond, A. C. Fabian +7

We report on a 120 ks Chandra/HETG spectrum of the black hole GRS 1915+105. The observation was made during an extended and bright soft state in June, 2015. An extremely rich disk…

Anatomy of the AGN in NGC 5548: VII. Swift study of obscuration and broadband continuum variability

M. Mehdipour, J. S. Kaastra, G. A. Kriss +16

We present our investigation into the long-term variability of the X-ray obscuration and optical-UV-X-ray continuum in the Seyfert 1 galaxy NGC 5548. In 2013 and 2014, the Swift ob…
