The Unusual Broadband X-ray Spectral Variability of NGC 1313 X-1 seen with XMMNewton, Chandra and NuSTAR

D. J. Walton, C. Pinto, M. Nowak +19

We present results from the major coordinated X-ray observing program on the ULX NGC 1313 X-1 performed in 2017, combining -, and , focusing on the e…

XMM-Newton Campaign On Ultraluminous X-ray Source NGC 1313 X-1: Wind vs. State Variability

C. Pinto, D. J. Walton, E. Kara +12

Most ultraluminous X-ray sources (ULXs) are thought to be powered by neutron stars and black holes accreting beyond the Eddington limit. If the compact object is a black hole or a…

The Hunt for Pulsating Ultraluminous X-ray Sources

X. Song, D. J. Walton, G. B. Lansbury +4

Motivated by the recent discoveries that six Ultraluminous X-ray Sources (ULXs) are powered by highly super-Eddington X-ray pulsars, we searched for additional pulsating ULX (PULX)…

The discovery of weak coherent pulsations in the ultraluminous X-ray source NGC 1313 X-2

R. Sathyaprakash, T. P. Roberts, D. J. Walton +8

We report the detection of weak pulsations from the archetypal ultraluminous X-ray source (ULX) NGC 1313 X-2. Acceleration searches reveal sinusoidal pulsations in segments of two…

Discovery of a 2.8 s pulsar in a 2 d orbit High-Mass X-ray Binary powering the Ultraluminous X-ray source ULX-7 in M51

G. A. Rodríguez Castillo, G. L. Israel, A. Belfiore +26

We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs…

Thermal stability of winds driven by radiation pressure in super-Eddington accretion disks

Ciro Pinto, Missagh Mehdipour, Dom J. Walton +7

Ultraluminous X-ray sources (ULXs) are mainly powered by accretion in neutron stars or stellar-mass black holes. Accreting at rates exceeding the Eddington limit by factors of a fe…
