... Special Reports Giant space cloud may be powered by black holes 17:57 23 April 2007 NewScientist.com news service David Shiga An enormous cloud of roiling plasma in space may be drawing its energy from black holes, new observations suggest. Such clouds might be sources for the mysterious particles that occasionally crash into Earth's atmosphere at ultra - high speed. ... But higher energy particles in the cloud may be able to escape, he says. ...

... Meta Index / Home Page / Description There are several different deadtime contributions that have to be taken into account during the EPIC pn ODF processing: one factor depends solely on the readout mode, the second is related to deadtimes due to discarded CCD columns because of on-board MIP (Minimum Ionizing Particle) rejection, the third factor represents additional deadtimes from MIP rejection per frame per CCD by ground software. ... MIP dependent quadrant livetime factor FC1 . ...
