The discovery of weak coherent pulsations in the ultraluminous X-ray source NGC 1313 X-2
R. Sathyaprakash, T. P. Roberts, D. J. Walton +8
We report the detection of weak pulsations from the archetypal ultraluminous X-ray source (ULX) NGC 1313 X-2. Acceleration searches reveal sinusoidal pulsations in segments of two…
AGN feedback in the Phoenix cluster
Ciro Pinto, Christopher J. Bambic, Jeremy S. Sanders +5
Active galactic nuclei (AGN) release a huge amount of energy into the intracluster medium (ICM) with the consequence of offsetting cooling and star formation (AGN feedback) in the…
The X-ray luminous cluster underlying the bright radio-quiet quasar H1821+643
H. R. Russell, A. C. Fabian, J. S. Sanders +4
We present a Chandra observation of the only low redshift, z=0.299, galaxy cluster to contain a highly luminous radio-quiet quasar, H1821+643. By simulating the quasar PSF, we subt…
