    • The high energy X-ray probe (HEX-P): a new window into neutron star accretion 

      Ludlam, R. M.; Malacaria, C.; Sokolova-Lapa, E.; Fuerst, F.; Pradhan, P.; Shaw, A. W.; Pottschmidt, K.; Pike, S.; Vasilopoulos, G.; Wilms, J.; García, J. A.; Madsen, K.; Stern, D.; Maitra, C.; Del Santo, M.; Walton, D. J.; Brumback, M. C.; van den Eijnden, J. (2023-12-12)
      Accreting neutron stars (NSs) represent a unique laboratory for probing the physics of accretion in the presence of strong magnetic fields (B ≳ 108 G). Additionally, the matter inside the NS itself exists in an ultra-dense, ...

    • The high energy X-ray probe (HEX-P): constraining supermassive black hole growth with population spin measurements 

      Piotrowska, J. M.; García, J. A.; Walton, D. J.; Beckmann, R. S.; Stern, D.; Ballantyne, D. R.; Wilkins, D. R.; Bianchi, S.; Boorman, P. G.; Buchner, J.; Chen, C.-T.; Coppi, P.; Dauser, T.; Fabian, A.C.; Kammoun, E.; Madsen, K.; Mallick, L.; Matt, G.; Matzeu, G.; Nardini, E.; Pizzetti, A.; Puccetti, S.; Ricci, C.; Tombesi, F.; Torres-Albà, N.; Wong, K.-W. (2024-03-28)
      Constraining the primary growth channel of supermassive black holes (SMBHs) remains one the most actively debated questions in the context of cosmological structure formation. Owing to the expected connection between SMBH ...

    • 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 ...

    • The High-Energy X-ray Probe (HEX-P): the circum-nuclear environment of growing supermassive black holes 

      The HEX-P Collaboration; Boorman, P. G.; Torres-Albà, N.; Annuar, A.; Marchesi, S.; Pfeifle, R. W.; Stern, D.; Civano, F.; Baloković, M.; Buchner, J.; Ricci, C.; Alexander, D. M.; Brandt, W. N.; Brightman, M.; Chen, C. T.; Creech, S.; Gandhi, P.; García, J. A.; Harrison, F.; Hickox, R.; Kammoun, E.; LaMassa, S.; Lanzuisi, G.; Marcotulli, L.; Madsen, K.; Matt, G.; Matzeu, G.; Nardini, E.; Piotrowska, J. M.; Pizzetti, A.; Puccetti, S.; Sicilian, D.; Silver, R.; Walton, D. J.; Wilkins, D. R.; Zhao, X. (2024-05-14)
      Ever since the discovery of the first active galactic nuclei (AGN), substantial observational and theoretical effort has been invested into understanding how massive black holes have evolved across cosmic time. Circum-nuclear ...
