    • The high energy X-ray probe ( HEX-P ): studying extreme accretion with ultraluminous X-ray sources 

      Bachetti, Matteo; Middleton, Matthew J.; Pinto, Ciro; Gúrpide, Andrés; Walton, Dominic J.; Brightman, Murray; Lehmer, Bret; Roberts, Timothy P.; Vasilopoulos, Georgios; Alford, Jason; Amato, Roberta; Ambrosi, Elena; Dai, Lixin; Earnshaw, Hannah P.; El Byad, Hamza; García, Javier A.; Luca Israel, Gian; Jaodand, Amruta; Madsen, Kristin; Maitra, Chandreyee; Mandel, Shifra; Mori, Kaya; Pintore, Fabio; Ohsuga, Ken; Pilia, Maura; Stern, Daniel; Younes, George; Wolter, Anna (2023-11-27)
      Introduction: Ultraluminous X-ray sources (ULXs) represent an extreme class of accreting compact objects: from the identification of some of the accretors as neutron stars to the detection of powerful winds travelling at ...

    • Orbital Decay in M82 X-2 

      Bachetti, Matteo; Heida, Marianne; Maccarone, Thomas; Huppenkothen, Daniela; Israel, Gian Luca; Barret, Didier; Brightman, Murray; Brumback, McKinley; Earnshaw, Hannah P.; Forster, Karl; Fürst, Felix; Grefenstette, Brian W.; Harrison, Fiona A.; Jaodand, Amruta D.; Madsen, Kristin K.; Middleton, Matthew; Pike, Sean N.; Pilia, Maura; Poutanen, Juri; Stern, Daniel; Tomsick, John A.; Walton, Dominic J.; Webb, Natalie; Wilms, Jörn (2022-10-05)
      M82 X-2 is the first pulsating ultraluminous X-ray source discovered. The luminosity of these extreme pulsars, if isotropic, implies an extreme mass transfer rate. An alternative is to assume a much lower mass transfer ...

    • The Variability Behavior of NGC 925 ULX-3 

      Earnshaw, Hannah P.; Brightman, Murray; Harrison, Fiona A.; Heida, Marianne; Jaodand, Amruta; Middleton, Matthew J.; Roberts, Timothy P.; Walton, Dominic J. (2022-07-25)
      We report the results of a 2019–2021 monitoring campaign with Swift and associated target-of-opportunity observations with XMM-Newton and NuSTAR, examining the spectral and timing behavior of the highly variable ultraluminous ...
