چکیده

PSR B0628-28 is a radio pulsar which was first detected in the X-ray band by ROSAT and then later observed with Chandra and XMM-Newton. The Chan-dra observation yielded an X-ray luminosity two orders of magnitude higher than what is expected for spin-powered pulsars, also there were no pulsations detected. The XMM-Newton observation, however, reveals pulsations at the expected radio period, P = 1.244 s. The simultaneously analyzed spectra also give a luminos-ity (in cgs) log L x = 30.34, which is ∼ 350 times greater than what would be expected from the correlation between L x-˙ E.

The Chandra Observations of the Two Pulsars PSR 0628 - 28 and PSR 1813 - 36

PSR 0628-28 is an X-ray emitting radio pulsar which was observed with Advanced CCD Imaging Spectrometer (ACIS) on board Chandra on 2001 November 04 and on 2002 March 25 for 2700 s and 17000 s, respectively. The source countrate was 0.0111±0.0008cps. We detected pulsations consistent with the radio frequency of f = 0.80370338 ± 0.000059 at a pulsed fraction 25.4%±%2 making PSR 062828 to be the l...

The democratization of the oncogene.

The identification of novel, oncogenic gene rearrangements in inflammatory myofibroblastic tumor demonstrates the potential of next-generation sequencing (NGS) platforms for the detection of therapeutically relevant oncogenes across multiple tumor types, but raises significant questions relating to the investigation of targeted therapies in this new era of widespread NGS testing.
