    • The high energy X-ray probe (HEX-P): magnetars and other isolated neutron stars 

      Alford, J. A. J.; Younes, G. A.; Wadiasingh, Z.; Abdelmaguid, M.; An, H.; Bachetti, M.; Baring, M. G.; Beloborodov, A.; Chen, A. Y.; Enoto, T.; García, J. A.; Gelfand, J. D.; Gotthelf, E. V.; Harding, A. K.; Hu, C-P.; Jaodand, A. D.; Kaspi, V.; Kim, C.; Kouveliotou, C.; Kuiper, L.; Mori, K.; Nynka, M.; Park, J.; Stern, D.; Valverde, J.; Walton, D. J. (2024-01-09)
      The hard X-ray emission from magnetars and other isolated neutron stars remains under-explored. An instrument with higher sensitivity to hard X-rays is critical to understanding the physics of neutron star magnetospheres ...

    • Long-term pulse period evolution of the ultra-luminous X-ray pulsar NGC 7793 P13 

      Fuerst, F.; Walton, D. J.; Heida, M.; Bachetti, M.; Pinto, C.; Middleton, M. J.; Brightman, M.; Earnshaw, H. P.; Barret, D.; Fabian, A. C.; Kretschmar, P.; Pottschmidt, K.; Ptak, A.; Roberts, T.; Stern, D.; Webb, N.; Wilms, J. (2021-07-16)
      Ultra-luminous X-ray pulsars (ULXPs) provide a unique opportunity to study super-Eddington accretion. We present the results of a monitoring campaign of ULXP NGC 7793 P13. Over our four-year monitoring campaign with Swift, ...

    • Probing the nature of the low state in the extreme ultraluminous X-ray pulsar NGC 5907 ULX1 

      Fuerst, F.; Walton, D. J.; Israel, Gian Luca; Bachetti, M.; Barret, D.; Brightman, Murray; Earnshaw, H. P.; Fabian, A.; Heida, M.; Imbrogno, M.; Middleton, M. J.; Pinto, C.; Salvaterra, R.; Roberts, T. P.; Castillo, G. A. Rodríguez; Webb, N. (2023-04-12)
      NGC 5907 ULX1 is the most luminous ultra-luminous X-ray pulsar (ULXP) known to date, reaching luminosities in excess of 1e41 erg/s. The pulsar is known for its fast spin-up during the on-state. Here, we present a long-term ...
