This all-sky image shows the spatial distribution over the whole sky of the galactic haze at 30 and 44 GHz, extracted from the Planck observations. In addition to this component, other foreground components such as charged particles accelerated radially, known as synchrotron radiation, thermal dust, spinning dust, and extragalactic point sources contribute to the total emission detected by Planck at these frequencies. ...

Comment on J2246-1206 . In contrast to the jet pointing to the NE in our image, the 5 GHz VLBI image of Shen et al. (1998) shows no indication of extended emission above the 20 mJy/beam level. Hong et al. (1999) find a jet component to the SE and identify that with a "superluminal" component possibly ejected in 1992. A 15 GHz image from the USNO database, taken nearly at the same epoch as the image of Hong et al. (1999) does not show any component at this position angle. ...

... In the spectrometry of point sources, the advantage of obtaining long slit spectra over using single aperture spectra is that it provides a simultaneous spectrum of the background on both sides of the point source. ... The STECF IRAF layered package "specres" provides two tasks to extract point source spectra from 2-D images (either longslit, multislit or cross-dispersed) and decompose the full background over the image. ... A Point Source Function spectrum image is required as a 2-D spectrum. ...

In this method the fields outside and inside a particle are represented by expansions in term of proper basis functions (practically always the vector spherical harmonics). Since the particle surface does not coincide with the coordinate surface, it is impossible to satisfy the boundary conditions exactly, and the expansions are limited by a finite number of terms, and the boundary conditions are considered in a finite set of points (matching points). ...

The problem of turbulence is one of the most important and challenging problem of the modern science. ... An experimental investigation of turbulent flows with special experimental setup and equipment, which allow to obtain reliable data with good precision, is very difficult and expensive process. ... The natural assumption for the theory of turbulence is that there exist some (unknown yet) general and universal properties for wide range of different turbulent flows. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...
