... The radio to X-ray continuum shape of quasars (gif), (Elvis et al., ... Plotted in log nufnu vs log nu (nu=frequency) space. ... Radio-loud, Radio-quiet: quasars that look virtually identical at all other wavelengths can differ by a 1000 in their radio emission. Radio-loud quasars have a powerful jet moving at relativistic speeds (i.e. close to the speed of light) made up of energetic particles, themselves moving near the speed of light in a magnetic field. ...

... Appropriate values of DIT the integration time (DIT secs) for each individual integration, are lmited by various considerations. N.B. Ndit individual Integration s each of DIT secs are coadded to form a single Exposure of time Ndit*DIT]. The recommended minimum DIT is one sec (the minimum possible exposure time) or the value at which the noise becomes sky (rather than detector) limited. ... The recommended maximum DIT is such as to keep the detector wells less than half full. ... 40 sec . ...

Calcium/Sodium in the Milky Way . ... We map out calcium II sodium I absorption - corresponding to Fraunhofer H, K D lines - induced by both the interstellar medium and the circumgalactic medium of the Milky Way. ... We show that the abundance of sodium with respect to neutral hydrogen stays roughly constant in different environments, while that of calcium decreases with column density. ... Here we show the maps of calcium and sodium in the Milky Way based on the obtained data. ... Projects | ...

REPORT ON PIERRE DELIGNE FELLOWSHIP, 2010 SERGEY OBLEZIN During 2010 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated to Lie groups of classical type. According to Givental the glN -Whittaker functions, being solutions to the quantum cohomology D-module QH (FlN ) of the complete flag variety FlN = GLN (C)/B , describe the corresponding equivariant Gromov-Witten invariants of FlN . ...

Next: CONCLUSION Up: CHIRPLET TRANSFORM SUBSPACES Previous: Nondilational Chirplet Transform . Suppose we choose a windowed sinusoidal FM signal for our mother chirplet. Such a signal has a frequency that periodically rises and falls (much like the vibrato of musical instruments or the wail of a police siren). ... Figure 14 . ... Using the warbling mother chirplet, we also computed the ``dilation-dilation'' ( ) plane of the chirplet transform (Fig. 16 ) for the pendulum data. ...

Next: Introduction . ... A spike immunity method of digital integrating radiometer signals in the jamming environment is described. ... The purpose of the method is real-time signal processing, and the basic is an alternative selection of the least offset signal estimation using nonparametric "Nearest Neighbor" rule. ... The additive spike-like jam makes the "tails" of the distribution "heavier" which leads to different offsets for linear and rank mean estimation on the integrating interval. ...

... LEFT?, expression, RIGHT?, %math? . where expression is %math or %math tag %math, see below. The BOX element is used for a variety of purposes: . ... The BOX element can be used with the LEFT and RIGHT tags for delimiters that stretch to match the size of the enclosed expression. ... Left delimiters should be given before the LEFT tag, while right delimiters should be given following the RIGHT tag, for instance: ( 1 + x ) f(x) = {(<left> f(x) = ( ----- ) 1+x<over> sin x ( sin x ) <right>)} . ...

... Its apparent diameter of 18.0 arc minutes corresponds to a linear extension of about 180 light years; Kenneth Glyn Jones mentions an estimate of even 20 arc minutes from deep photographic plates, corresponding to about 200 light years linear diameter.
