Swift monitoring of M51: A 38-day super-orbital period for the pulsar ULX7 and a new transient ULX
Murray Brightman, Hannah Earnshaw, Felix Fürst +6
We present the results from a monitoring campaign made with the Neil Gehrels Swift Observatory of the M51 galaxies, which contain several variable ultraluminous X-ray sources (ULXs…
A broadband look at the old and new ULXs of NGC 6946
Hannah P. Earnshaw, Brian W. Grefenstette, Murray Brightman +8
Two recent observations of the nearby galaxy NGC 6946 with NuSTAR, one simultaneous with an XMM-Newton observation, provide an opportunity to examine its population of bright accre…
Observing the transient pulsations of SMC X-1 with NuSTAR
Sean N. Pike, Fiona A. Harrison, Matteo Bachetti +6
We report on NuSTAR observations of transient pulsations in the neutron star X-ray binary SMC X-1. The transition from non-pulsing to pulsing states was not accompanied by a large…
