. Comment on J1130-1449 . There are two dominant components in our image. Comparison with the 15 GHz image of Kellermann et al. (1998) reveals that the western component is brighter at the higher frequency, indicating that the brighter (eastern) component in our image may have a steep spectrum. VLBApls home page .

A New Mass Model For The JVAS Gravitational Lens B1030+074. ... University of Manchester, Jodrell Bank, U.K. B1030+074 is a double image gravitational lens, which was dis- covered during the Jodrell Bank VLA Astrometric Survey (JVAS). ... HST WFPC2 observations have revealed the lensing galaxy, which lies close to component B. The redshifts of the lensing galaxy and the background source have also been obtained and are 0.599 and 1.535 respectively. ...

... Archives . ... The PCA and ICA is used for separating mixed components with some assumptions. ... The need of source separation methods in astronomy has led various adaptations of decomposition methods available. ... I rarely come up with a paper which gathered and summarized component separation methods applicable to astronomical data. In that regards, the following paper seems useful to overview methods of reducing dimensionality for astronomers. [arxiv:0805.0269] . ... Chandra Blog . ...

... Among the objectives of Principal Components Analysis are the following. dimensionality reduction; љ . the determining of linear combinations of variables; љ . ... identification of groups of objects or of outliers. ... Finding a set of principal axes allows the objects to be adequately characterised on a smaller number of (artificial) variables. ... Reduction of dimensionality is practicable if the first new axes account for approximately 75 % or more of the variance. ...

... 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. ...

GJ 900 - a new hierarchical system with low-mass components E. Malogolovets, Yu. Balega, D. Rastegaev, K.-H. Hofmann, G. Weigelt Speckle interferometric observations made with the 6 m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences in 2000 revealed the triple nature of the nearby (d=19.3 pc) low-mass young (age about 200 Myr) star GJ 900. The configuration of the triple system allowed it to be dynamically unstable. ...

... GSAOI Home . ... Science . ... For example, among the Milky Way's dE companions we see systems with dominant old populations, systems with minor intermediate-age (age ~ 2 to 10 Gyr) components, and systems where the intermediate-age component dominates the old stars. ... This variety of star formation histories is not restricted to the Galaxy's companions. ... To make progress in understanding the processes that govern dwarf galaxy evolution, we need to study systems beyond the Local Group. ...

Seven months ago, on Mar 19, 2008, at 09:12 Moscow time, a new star appeared on the sky. The Sun had already risen over the Russia, but people of the Western hemisphere might be able to see by their eyes a faint starlet near one of Bootes constellation stars. This starlet appeared and faded by an order of magnitude in a minute. Astronomers named it GRB080319B or, informally, the Naked-Eye Burst, as it was twice as bright as human eye can see a star. ...

... The fitting procedure will only converge to a unique solution if the components are linearly independent. ... The task calculates for each pair of component images and fails with an error if any is greater than 0.99. ... Hence components may be linearly independent in masked pixels yet still fail the test within the task. ... Finally, since the Poisson image values are necessarily all , negative values are not allowed in the model components. ...

Environments of Active Close Binaries I: ER Vulpeculae A.G. Gunn and J.G. Doyle A&A, in press High­resolution observations of the eclipsing active close binary system ER Vulpeculae have revealed excess emission in the Hff, the Ca II IRT and the Mg I b lines and excess absorption in the He I D 3 line. ... Analysis has revealed that the emission arises in plage­like material cov­ ering perhaps half of the secondary's surface. ...
