The expected potential of hadronic PeVatron searches with spectral -ray data from the Southern Wide-field Gamma-ray Observatory
Ekrem Oğuzhan Angüner, Tülün Ergin
The presence of a spectral softening, occurring at 3 PeV energies, seen in the local cosmic-ray energy spectrum provides an evidence that our Galaxy hosts astrophysical objects, kn…
Timing analysis of Swift J0243.6+6124 with NICER and Fermi/GBM during the decay phase of the 2017-2018 outburst
M. M. Serim, Ç. K. Dönmez, D. Serim +3
We present a timing and noise analysis of the Be/X-ray binary system Swift J0243.6+6124 during its 2017-2018 super-Eddington outburst using NICER/XTI observations. We apply a synth…
Pulse Frequency Fluctuations of Persistent Accretion Powered Pulsars
D. Serim, M. M. Serim, A. Baykal
In this study, we examine the long term torque noise fluctuations of persistent Xray binaries Her X-1, Vela X-1, GX 301-2, CEN X-3, 4U 1538-53, OAO 1657-415 and 4U 1626-67 using th…
Optical Counterparts of ULXs and Their Host Environments in NGC 4490/4485
Senay Avdan, Aysun Akyuz, Alexander Vinokurov +6
We report the identification of the possible optical counterparts of five out of seven Ultraluminous X-ray Sources (ULXs) in NGC 4490/4485 galaxy pair. Using archival Hubble Space…
Discovery of a Glitch in the Accretion Powered Pulsar SXP 1062
M. M. Serim, S. Sahiner, D. Cerri-Serim +2
We present timing analysis of the accretion powered pulsar SXP 1062, based on the observations of \textit{Swift}, \textit{XMM-Newton} and \textit{Chandra} satellites covering a tim…
A Reanalysis of High Resolution XMM-Newton Data of V2491 Cyg Using Collisionally Ionized Hot Absorber Models
Solen Balman, Cigdem Gamsizkan
We present a reanalysis of XMM-Newton Reflection Grating Spectrometer data of the classical nova V2491 Cyg obtained from two different pointings, 40 d and 50 d after outburst utili…
