... The calibration of astrophysical spectra in wavelength based on calibration lamp data suffers from different kinds of uncertainties. Besides inaccuracies in the observational phase, common data reduction practice adds ``pixelation'' errors, due to the fact that the centering method does not use the correct PSF. These model mismatch errors depend, for a given feature, on the sub-pixel location of the line center (David & Verschueren, private communication). ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... 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. The velocity acquired in falling towards the black hole also helps it escape. ...

The merging galaxy Arp 220 is the prototypical luminous infrared galaxy. ... In 1996, one of the then largest VLBI experiments was conducted on Arp 220, using the compact OH maser peak as a convenient phase reference. This permitted continuum imaging of the galaxy with high sensitivity, revealing the existence of roughly a dozen unresolved sub-mJy point sources scattered across the nuclear region of the galaxy. ...
