Discovery of a ~30-Year-Duration Post-Nova Pulsating Supersoft Source in the Large Magellanic Cloud
G. Vasilopoulos, F. Koliopanos, T. E. Woods +3
Supersoft X-ray sources (SSS) have been identified as white dwarfs accreting from binary companions and undergoing nuclear-burning of the accreted material on their surface. Althou…
Revisiting the spectral and timing properties of 4U 1909+07 with NuSTAR and Astrosat
Gaurava K. Jaisawal, Sachindra Naik, Wynn C. G. Ho +3
We present the results obtained from the analysis of high mass X-ray binary pulsar 4U 1909+07 using NuSTAR and Astrosat observations in 2015 and 2017 July, respectively. X-ray puls…
NuSTAR X-ray spectrum of Be-X-ray pulsar Swift J1845.7-0037: Bulk and thermal Comptonization of cyclotron seed photons in the accretion column
Filippos Koliopanos, Georgios Vasilopoulos, Michael T. Wolff
Aims: Spectral and temporal analysis of the NuSTAR observation Galactic Be-XRB Swift J1845.7-0037. during its recent outburst. Methods: For the spectral analysis we use both phenom…
M51 ULX-7: super-orbital periodicity and constraints on the neutron star magnetic field
G. Vasilopoulos, S. K. Lander, F. Koliopanos +1
In the current work we explore the applicability of standard theoretical models of accretion to the observed properties of M51 ULX-7. The spin-up rate and observed X-ray luminosity…
Neutron Stars and Black Holes in the Small Magellanic Cloud: The SMC NuSTAR Legacy Survey
M. Lazzarini, B. F. Williams, A. E. Hornschemeier +18
We present a source catalog from the first deep hard X-ray ( keV) survey of the Small Magellanic Cloud (SMC), the NuSTAR Legacy Survey of the SMC. We observed three fields, f…
EXTraS discovery of two pulsators in the direction of the LMC: a Be/X-ray binary pulsar in the LMC and a candidate double-degenerate polar in the foreground
F. Haberl, G. L. Israel, G. A. Rodriguez Castillo +10
The EXTraS project to explore the X-ray Transient and variable Sky searches for coherent signals in the X-ray archival data of XMM-Newton. XMM-Newton performed more than 400 pointe…
