We present an analysis of the diffuse soft X-ray emission from the nuclear region of M51 combining both XMM-Newton RGS and Chandra data.Most of the RGS spectrum
The recent discoveries of pulsed X-ray emission from three ultraluminous X-ray(ULX)sources have finally enabled us to recognize a subclass within the ULX class:
Type Ia supernovae(SNe Ia) play an important role in studies of cosmology and galactic chemical evolution.They are believed to be thermonuclear explosions of ca
By introducing the Dirac δ-function and Pauli exclusion principle in the presence of superstrong magnetic fields(SMFs), we investigate the influence of SMFs on b
