Sub-arcsecond radio and optical observations of the likely counterpart to the gamma-ray source 2FGL J2056.7+4939
Luque-Escamilla, P. L.; Martí, J.; Muñoz-Arjonilla, A. J. +1 more
We have searched and reviewed all multi-wavelength data available for the region towards the gamma-ray source 2FGL J2056.7+4939 in order to constrain its possible counterpart at lower energies. As a result, only a point-like optical/infrared source with flat-spectrum radio emission is found to be consistent with all X-ray and gamma-ray error circl…
X-Ray Spectral Study of AGN Sources Content in Some Deep Extragalactic XMM-Newton Fields
Misra, R.; Hassan, M. A.; Korany, B. A. +3 more
We undertake a spectral study of a sample of bright X-ray sources taken from six XMM-Newton fields at high galactic latitudes, where AGN are the most populous class. These six fields were chosen such that the observation had an exposure time more than 60 ksec, had data from the EPIC-pn detector in the full-Frame mode and lying at high galactic lat…
