A FAST search for radio pulsations during the dormant state of the AMSPs IGR J00291+5934 and MAXI J1957+032

A. Marino, E. Parent, F. Coti Zelati +15

Accreting millisecond pulsars (AMSPs) and transitional millisecond pulsars (tMSPs) are neutron star low-mass X-ray binaries which can evolve into "recycled" radio millisecond pulsa…

Deep optical spectroscopic monitoring of the pulsating ULX NGC 1313 X-2 with longslit Gemini observations

Rajath Sathyaprakash, Timothy. P. Roberts

This study reports the nature of the companion star to the pulsating ULX NGC 1313 X-2, using long-slit spectroscopic data from Gemini-South observations, based on archival data fro…

New interpretation of the two hard X-ray sources IGR J17503-2636 and IGR J17507-2647

L. Sidoli, V. Sguera, P. Esposito +4

We report on the results of X-ray observations (XMM-Newton, INTEGRAL and Swift) of two hard X-ray sources, IGR J17503-2636 and IGR J17507-2647, whose nature is not fully elucidated…

The long-term variability of a population of ULXs monitored by Chandra

Hannah P. Earnshaw, Gauri Patti, Murray Brightman +5

We present preliminary results of a Chandra Large Program to monitor the ultraluminous X-ray source (ULX) populations of three nearby, ULX-rich galaxies over the course of a year,…

A New Broadband Spectral State in the Ultraluminous X-ray Source Holmberg IX X-1

D. J. Walton, M. Bachetti, P. Kosec +12

We present a series of five new broadband X-ray observations of the ultraluminous X-ray source Holmberg IX X-1, performed by - and in coordination. The first…

Exploring the case for hard-X-ray beaming in NGC 6946 X-1

Tobias Beuchert, Matthew J. Middleton, Roberto Soria +5

In order to understand the nature of super-Eddington accretion we must explore both the emission emerging directly from the inflow and its impact on the surroundings. In this paper…
