NuSTAR reveals the hidden nature of SS433

M. J. Middleton, D. J. Walton, W. Alston +25

SS433 is the only Galactic binary system known to persistently accrete at highly super-critical (or hyper-critical) rates, similar to those in tidal disruption events, and likely n…

Discovery of pulsation dropout and turn-on during the high state of the accreting X-ray pulsar LMC X-4

McKinley C. Brumback, Ryan C. Hickox, Matteo Bachetti +6

Two \textit{NuSTAR} observations of the luminous X-ray pulsar LMC X-4 in October and November 2015 captured several bright accretion flares from this source, which has a long histo…

Investigating the high-frequency spectral features of SNRs Tycho, W44 and IC443 with the Sardinia Radio Telescope

S. Loru, A. Pellizzoni, E. Egron +20

The main characteristics in the radio continuum spectra of Supernova Remnants (SNRs) result from simple synchrotron emission. In addition, electron acceleration mechanisms can shap…

Gazing at the ultra-slow magnetar in RCW 103 with NuSTAR and Swift

A. Borghese, F. Coti Zelati, P. Esposito +6

We report on a new NuSTAR observation and on the ongoing Swift XRT monitoring campaign of the peculiar source 1E 161348-5055, located at the centre of the supernova remnant RCW 103…

A Potential Cyclotron Resonant Scattering Feature in the ULX Pulsar NGC 300 ULX1 seen by NuSTAR and XMM-Newton

D. J. Walton, M. Bachetti, F. Fuerst +14

Based on phase-resolved broadband spectroscopy using - and , we report on a potential cyclotron resonant scattering feature at keV in the pulsed sp…

Evidence for Pulsar-like Emission Components in the Broadband ULX Sample

D. J. Walton, F. Fuerst, M. Heida +7

We present broadband X-ray analyses of a sample of bright ultraluminous X-ray sources with the goal of investigating the spectral similarity of this population to the known ULX pul…
