A Newly Identified Transient Ultraluminous X-ray Source in M31

Ferdinand, Murray Brightman, Jean-Marie Hameury +9

Ultraluminous X-ray sources (ULXs) are off-nuclear X-ray sources with luminosities exceeding the Eddington limit of typical stellar-mass compact objects. While most known ULXs are…

A Multi-Wavelength Picture of the Surprisingly Short 2024/25 Outburst from EXO 0748-676

Amy H. Knight, Lauren Rhodes, Noel Castro Segura +11

After sixteen years in quiescence, EXO 0748-676 unexpectedly returned to outburst in March 2024. However, in stark contrast to its previous outburst (1985 - 2008), EXO 0748-676 ret…

A Broadband X-ray Analysis and Optical Counterpart Search of IC5052 ULX

Nabil Brice, Dominic J. Walton, Felix Fürst +10

We present broadband X-ray spectral and timing analysis of the Ultra-luminous X-ray source (ULX) in IC5052 using simultaneous XMM-Newton and NuSTAR observations from 2022, suppleme…

A NuSTAR study of quasi-periodic oscillations from the ultraluminous X-ray sources in M82

Hamza El Byad, Matteo Bachetti, Silvia Columbu +13

The study of quasi-periodic oscillations in X-ray binaries provides valuable insights into the physics of accretion around compact objects. The M82 galaxy hosts two ultraluminous X…

XMM-Newton Conclusively Identifies an Active Galactic Nucleus in a Green Pea Galaxy

Peter G. Boorman, Jiří Svoboda, Daniel Stern +23

Green Pea galaxies are a class of compact, low-mass, low-metallicity star-forming galaxies in the relatively local universe. They are believed to be analogues of high-redshift gala…

Long timescale numerical simulations of large, super-critical accretion discs

P. Chris Fragile, Matthew J. Middleton, Deepika A. Bollimpalli +1

In this paper, we report on three of the largest (in terms of simulation domain size) and longest (in terms of duration) 3D general relativistic radiation magnetohydrodynamic simul…
