Simultaneous Optical and X-ray Detection of a Thermonuclear Burst in the 2024 Outburst of EXO 0748-676
Amy H. Knight, Lauren Rhodes, Douglas J. K. Buisson +5
The neutron star low-mass X-ray binary, EXO 0748--676, recently returned to outburst after a 16 year-long quiescence. Since its return, there has been a global effort to cap…
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…
Skipping a beat: discovery of persistent quasi-periodic oscillations associated with pulsed fraction drop of the spin signal in M51 ULX-7
Matteo Imbrogno, Sara Elisa Motta, Roberta Amato +24
The discovery of pulsations in (at least) six ultraluminous X-ray sources (ULXs) has shown that neutron stars can accrete at (highly) super-Eddington rates, challenging the standar…
Detection of a Highly Ionized Outflow in the Quasi-periodically Erupting Source GSN 069
P. Kosec, E. Kara, L. Brenneman +8
Quasi-periodic eruptions (QPEs) are high-amplitude, soft X-ray bursts recurring every few hours, associated with supermassive black holes. Many interpretations for QPEs were propos…
Absence of nebular He{\sc ii} 4686 constrains the UV emission from the Ultraluminous X-ray pulsar NGC~1313~X--2
Andrés Gúrpide, Noel Castro Segura, Roberto Soria +1
While much has been learned in recent decades about the X-ray emission of the extragalactic Ultraluminous X-ray sources (ULXs), their radiative output in the UV band remains poorly…
