Study and reproducibility of the SRG/eROSITA background with particle rejection on and off Perinati, Emanuele; Freyberg, Michael J.; Pommranz, Christian; Serim, Muhammed Miraç; Yeung, Michael C. H.; Dennerl, Konrad; Friedrich, Susanne; Tenzer, Chris; Santangelo, Andrea (2025-10-01) For more than six years SRG/eROSITA is the first X-ray telescope in orbit around the second Lagrangian point in the Sun-Earth system. We present an updated study of its instrumental background based on cleaned data and imp...
Searching for orbital period modulation in X-ray observations of the symbiotic X-ray binary GX 1+4 Klawin, Moritz; Ducci, Lorenzo; Serim, Muhammed Miraç; Santangelo, Andrea; Ferrigno, Carlo; Bozzo, Enrico (2024-11-01) The symbiotic X-ray binary GX 1+4 possesses a number of peculiar properties that have been studied since the early 1970s. In particular, the orbital period has been a point of debate for many years, until radial velocity m...
The high-energy cyclotron line in 2S 1417-624 discovered with Insight-HXMT during the 2018 outburst Liu, Q.; Santangelo, A.; Kong, L. D.; Ducci, L.; Ji, L.; Wang, W.; Serim, Muhammed Miraç; GÜNGÖR, Can; Tuo, Y. L.; Serim, D. (2024-11-01) We report a detailed timing and spectral analysis of the X-ray pulsar 2S 1417-624 using the data from Insight-HXMT during the 2018 outburst. The pulse profiles are highly variable with respect to both unabsorbed flux and e...
Discovery of the First Antiglitch Event in the Rotation-powered Pulsar PSR B0540-69 Tuo, Youli; Serim, Muhammed Miraç; Antonelli, Marco; Ducci, Lorenzo; Vahdat, Armin; Ge, Mingyu; Santangelo, Andrea; Xie, Fei (2024-05-01) Using data from the Neutron star Interior Composition ExploreR observatory, we identified a permanent spin frequency decrease of Delta nu = -(1.04 +/- 0.07) x 10-7 Hz around MJD 60132 in the rotation-powered pulsar PSR B05...
Probing the emission mechanism and nature of the pulsating compact object in the X-ray binary SAX J1324.4-6200 Ducci, L.; Bozzo, E.; Burgay, M.; Malacaria, C.; Ridolfi, A.; Romano, P.; Serim, Muhammed Miraç; Vercellone, S.; Santangelo, A. (2024-05-01) Recently, there has been renewed interest in the Be X-ray binary (Be/XRB) SAX J1324.4-6200 because of its spatial coincidence with a variable gamma-ray source detected by Fermi/LAT. To explore more thoroughly its propertie...
SRG/eROSITA background analysis and simulation Perinati, Emanuele; Freyberg, Michael J.; Pommranz, Christian M.; Serim, Muhammed Miraç; Yeung, Michael C. H.; Dennerl, Konrad; Friedrich, Susanne; Tenzer, Chris; Santangelo, Andrea (2024-01-01) For about five years SRG/eROSITA is the first X-ray telescope in orbit around the second Lagrangian point L2. We present an updated study of its instrumental background based on cleaned data and improved simulations, carri...
