X-ray Polarization of the Eastern Lobe of SS 433

Philip Kaaret, Riccardo Ferrazzoli, Stefano Silvestri +103

How astrophysical systems translate the kinetic energy of bulk motion into the acceleration of particles to very high energies is a pressing question. SS 433 is a microquasar that…

A Full Characterisation of the Supermassive Black Hole in IRAS 09149-6206

D. J. Walton, W. N. Alston, P. Kosec +11

We present new broadband X-ray observations of the type-I Seyfert galaxy IRAS 09149-6206, taken in 2018 with -, and . The source is highly complex, sho…

A Low-Flux State in IRAS 00521-7054 seen with NuSTAR and XMM-Newton: Relativistic Reflection and an Ultrafast Outflow

D. J. Walton, E. Nardini, L. C. Gallo +8

We present results from a deep, coordinated -+ observation of the Seyfert 2 galaxy IRAS 00521-7054. The data provide the first detection of this sourc…

Detection of Reflection Features in the Neutron Star Low-Mass X-ray Binary Serpens X-1 with NICER

R. M. Ludlam, J. M. Miller, Z. Arzoumanian +17

We present Neutron Star Interior Composition Explorer (NICER) observations of the neutron star low-mass X-ray binary Serpens X-1 during the early mission phase in 2017. With the hi…

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…

Long term variability of Cygnus X-1: VII. Orbital variability of the focussed wind in Cyg X-1 / HDE 226868 system

V. Grinberg, M. A. Leutenegger, N. Hell +8

Binary systems with an accreting compact object are a unique chance to investigate the strong, clumpy, line-driven winds of early type supergiants by using the compact object's X-r…
