... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

... The reduction system of observations FADPS (description in Russian) (Flexible Astronomical Data Processing System) for data of wide-band receivers of the first observation cabin of the radio telescope RATAN-600 had been created under the Unix-like operational system DEMOS for computers of the SM-1420-type (PDP/11) in 1987 for observation analysis and estimates of coordinates and flux densities of radio sources. ...

... An analysis on new observational data taken with the MPFS and SCORPIO spectrographs indicates that we are dealing with the "galactic wind": the gas is blown above the galactic plane with the characteristic velocity of about 130km/s. The gas outflow is caused by a combined action of winds from the supernovae and young massive stars located in the galaxy's circumnuclear region. ... The most probable hypothesis is that the accretion of intergalactic gas clouds is feeding their star formation. ...

... AstroCC is a coordinate conversion utility for astronomy. It accepts an object designation or the coordinates of an object and calculates coordinates in alternative systems, and at different dates, times, and locations. It also provides lunar and bright planet coordinates to aid in planning observations. ... BJD values may also be retrieved from http://astroutils.astronomy.ohio-state.edu/time/utc2bjd.html which is based on Eastman et al. ... Coordinate data are obtained from SIMBAD. ...

... Figure 1a illustrates the summary diagram (2 log L, log S ) based on the field intensity contour lines for 7 active regions plotted at 200 G steps in the range of 2200­400 G. One can see that the relationship under discussion is well represented by two straight lines, one corresponding to the log S range from 2 to 7.2 and another, from 7.2 to 9. ... Then, we plotted 2 log L versus log S for all field lines of a given intensity, no matter which sunspot or sunspot group they belonged to. ...
