XMM-Newton Science Analysis System . ... For those whose heads began to ache at around the second equation, think of it this way: at each pixel of the image, the probability of recording events is given by the Poisson distribution corresponding to the expectation value . ... We can then assign a probability to the pixel value from equation 5 . Now let us multiply all the probabilities for individual pixels together. ... XMM-Newton SOC/SSC -- 2007-07-09 ...

... Most Luminous Supernovae as Strong Radiative Shocks . Discovery of the extremely luminous supernova SN2006gy has demonstrated that some of those events produce an order of magnitude more visible photons than other, already powerful explosions. I discuss models that were invoked earlier to explain unusual properties of other powerful supernovae with narrow emission lines in their spectra. ...

The centroid velocities of the following emission lines were measured: FeII (5 lines), [N II] 5754.59A (NIST Database), H_alpha, H_beta, HeI (5 lines), and [O III] 5006.843A. FeII and [N II] lines that form in the cool equatorial disk wind of B[e] star have stable sharp-edge profiles. ... All the FeII lines and the [N II] line in our spectra show a linear shift with time. ...
