The black hole. ... The black holes are generated in the result of a collapse of giant stars with the mass more than three Sun's masses. ... And moreover the gas near the neutron star or the black hole will get hot and will become a source of high energetic electromagnetic radiation in X-rays and gamma range. ... In the majority of double systems, being the sources of X-rays radiation, the invisible component mass does not exceed the two solar masses, so it is a neutron star. ...

However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. ... Far from being a voracious devourer of stars and of interstellar gas, "our own" black hole is rather benign. ... What holds galaxies together? ...

... Anticipated Radiation Effects . ... Various radiation effects can be anticipated, based on similarities to other CMOS devices. ... Total dose radiation effects in CMOS devices can be divided into two broad classes: charge trapping and interface state generation. ... When interface states are located in a depletion region, they act as sources of dark current. Increased dark current is expected to be the dominant radiation effect in active pixel sensors, leading to increased shot noise. ...
