But also, we need simple RFI removal software. ... This also relates to the issue of maximum BW: 100 or 200 MHz bandwidth? From my experience, the spectrum seems to be pretty clean out to 1225 MHz, and so there is a case for 200 MHz bandwidth. ...

... Radio emission at around 90 GHz from star-forming galaxies is expected to be strongly dominated by the free-free component due to ionising radiation from massive, short-lived, stars. We present high surface-brightness sensitivity observations at 90 GHz of the nearby star-forming galaxy Messier 66 with resolution of about 9 arcsec (corresponding to a physical scale of about 500 pc) and analyse these observations in combination with archival lower frequency radio and mid-infrared measurements. ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

... For the Corner Method, Clean_lc was originally a FORTRAN 77 program developed by Steve Snowden and Kip Kuntz in 2005-6. ... Clean_lc's purpose is to clean a light curve by creating a histogram of rate values from the light curve, finding the most likely value assuming that to be similar to the mean of the quiescent rate, then fitting a Gaussian to a small window around that value in the histogram to determine the true mean and dispersion of the quiescent background rate. ...
