X-Ray Observations of an Intermediate Polar V2400 Oph
Pandey, J. C.; Singh, Harinder P.; Joshi, Arti
Based on the X-ray observations from XMM-Newton and Suzaku satellites at four different epochs, we present temporal and spectral properties of an intermediate polar (IP) V2400 Oph (=RX J1712.6-2414). The X-ray variations are found to occur at the spin and synodic periods and are derived to be 929 s and 1003 s, respectively. The X-ray spectrum is s…
IACHEC Cross-calibration of Chandra, NuSTAR, Swift, Suzaku, XMM-Newton with 3C 273 and PKS 2155-304
Miller, Eric D.; Guainazzi, Matteo; Madsen, Kristin K. +5 more
On behalf of the International Astronomical Consortium for High Energy Calibration, we present results from the cross-calibration campaigns in 2012 on 3C 273 and in 2013 on PKS 2155-304 between the then active X-ray observatories Chandra, NuSTAR, Suzaku, Swift, and XMM-Newton. We compare measured fluxes between instrument pairs in two energy bands…
The γ-Ray Detected Narrow-line Seyfert 1 Galaxy 1H 0323+342: Swift Monitoring and Suzaku Spectroscopy
Komossa, S.; Yuan, Weimin; Fuhrmann, L. +3 more
As a radio-loud narrow-line Seyfert 1 galaxy (NLS1) detected by Fermi/LAT in GeV γ-rays, 1H 0323+342 is a remarkable active galactic nucleus showing properties characteristic of both NLS1s and blazars. Here we present results of simultaneous X-ray and UV/optical monitoring observations on 1H 0323+342 taken with the UV/Optical Telescope and X-ray T…
