... We have been using it to analyze PC images of known gravitational lenses and QSOs which are candidates for lensing (Falco 1993). ... Fig. 1 plots the higher contours of the PC image of 0142 in the upper left, and its power spectrum in the upper right. ... If we fit the envelope of the power spectrum with a binary model, we find that best fit gives a separation of the two components of 1.3 PC pixels or about 58 mas. ... The lower two curves are cuts through the 0142 power spectrum. ...

. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000

... A typical spectrum (such as Figure 1) shows the classic triple-peaked spectrum, which is associated with masers located in a circumnuclear disk (e.g. NGC 4258, Nakai et al., ... The Circinus galaxy megamasers are known to be variable on timescales of weeks and months with individual maser features having a lifetime of around one year. ... Most of the masers observed showed some degree of variability over an hour while one feature displayed a doubling of its flux density over about 10 minutes. ...

... Since moonshine is really reflected sunlight, the full Moon is on the average slightly brighter in mid-winter, when Earth is closest to the Sun. In addition, the distance of the full Moon also varies, due to the ellipticity ("eccentricity") of the Moon's orbit. On 22 December, 1999, the two effects combined to produce the brightest full Moon of the century. ... This year will be the first full moon to occur on the winter solstice, Dec. 22nd, commonly called the first day of winter. ...

... Much of the cold atomic hydrogen in the interstellar medium can only be studied skiagraph- ically as H i self-absorption (HISA) shadows against background H i 21cm emission. ... The brightness of the H i behind the HISA is estimated from emission adjacent to the HISA features in space and velocity, and this background intensity is then used to nd the amount of absorption and various gas properties. ... The strongest HISA appears to congregate in lamentary complexes. ... Strong vs. ...
