... This is generally not a problem for point sources but for regions of extended emission it can cause an extracted spectrum to be a mix of flux from different areas of an object. It may be possible to disentangle the true sky emission by simultaneously fitting different spectral files. In this case an ARF giving the expected contribution (effective area) of flux received in one area from a different area is needed. ...

To locate it, look along the imaginary line between the two end stars on the leading edge of the PloughтАЩs blade (Merak and Dubhe) and Polaris (the North Star), the galaxy M82 (also known as the Cigar Galaxy) along with its companion M81, lies just off this line about a third of the way between the Plough and Polaris. €а€аAs usual, the supernova is far brighter than its home galaxy, appearing as an extra star. ...

When most people think of a supernova (SN), they picture a single massive star exploding. ... The way the physics works, if the supernova expels more than half the total mass of both stars combined, the two stars will fly apart. For example, let's say the star that blows up masses 10 times the Sun's mass, and the companion masses twice the Sun. ...

. Comment on J1232-0224 . Hooimeyer et al (1992a) detected the source on the Green Bank-Owens Valley baseline at 5 GHz (correlated flux density 180 mJy) and found that the nuclear emission was probably diffuse. The jet position angle in a 1.4 GHz VLA image (Hintzen, Ulvestad & Owen 1983) is similar to that in our VLBA image. Our image is consistent with the images at 2.3 and 8.4 GHz from the VLBA Calibrators database. VLBApls home page . Last modified: 16 Oct 2000
