A deep ensemble approach to X-ray polarimetry
CoRR, 2021 X-ray polarimetry will soon open a new window on the high energy universe with the launch of NASA's Imaging X-ray Polarimetry Explorer (IXPE). Polarimeters are currently limited by their track reconstruction algorithms, which typically use linear estimators and do not consider individual event quality.A. L. Peirson, R. W.

Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT X Persei is a persistent low-luminosity X-ray pulsar of period of ≈ 835 s in a Be binary system. The field strength at the neutron star surface is not known precisely, but indirect signs indicate a magnetic field above 1013 G, which makes the object one of the most magnetized known X-ray pulsars.Mushtukov, A A, Tsygankov, S S, Poutanen, J, Doroshenko, V, Salganik, A, Costa, E, Marco, A Di, Heyl, J, Monaca, F La, Lutovinov, A A, Mereminsky, I A, Papitto, A, Semena, A N, Shtykovsky, A E, Suleimanov, V F, Forsblom, S V, González-Caniulef, D, Malacaria, C, Sunyaev, R A, Agudo, I, Antonelli, L A, Bachetti, M, Baldini, L, Baumgartner, W H, Bellazzini, R, Bianchi, S, Bongiorno, S D, Bonino, R, Brez, A, Bucciantini, N, Capitanio, F, Castellano, S, Cavazzuti, E, Chen, C-T, Ciprini, S, De , Rosa, A, Del Monte, E, Gesu, L Di, Lalla, N Di, Donnarumma, I, Dovčiak, M, Ehlert, S R, Enoto, T, Evangelista, Y, Fabiani, S, Ferrazzoli, R, Garcia, J A, Gunji, S, Hayashida, K, Iwakiri, W, Jorstad, S G, Kaaret, P, Karas, V, Kislat, F, Kitaguchi, T, Kolodziejczak, J J, Krawczynski, H, Latronico, L, Liodakis, I, Maldera, S, Manfreda, A, Marin, F, Marscher, A P, Marshall, H L, Massaro, F, Matt, G, Mitsuishi, I, Mizuno, T, Muleri, F, Negro, M, Ng, C-Y, O’Dell, S L, Omodei, N, Oppedisano, C, Pavlov, G G, Peirson, A L, Perri, M, Pesce-Rollins, M, Petrucci, P-O, Pilia, M, Possenti, A, Puccetti, S, Ramsey, B D, Rankin, J, Ratheesh, A, Roberts, O J, Romani, R W, Sgrò, C, Slane, P, Soffitta, P, Spandre, G, Swartz, D A, Tamagawa, T, Tavecchio, F, Taverna, R, Tawara, Y, Tennant, A F, Thomas, N E, Tombesi, F, Trois, A, Turolla, R, Vink, J, Weisskopf, M C, Wu, K, Xie, F, Zane, S +106 moreopenaire +9 more sourcesThe X-ray polarimetry window reopens [PDF]
