... Image Quality of the VLT . Total Optical Control . First light for the ESO VLT unit telescope 1 occurred during the workshop. ... The image shown (Figure 1 ) here was obtained with the VLT on May 16, 1998, in red light (R band), i.e. while the mirror was still uncoated. ... In this diagram (FIgure 2), the measured image quality of the VLT UT1 astronomical images is plotted versus the ``seeing", as measured by the Seeing Monitor, a small telescope also located on top of the Paranal Mountain. ...

Analysis of the Systematic Errors of CCD-observations of Asteroids Performed in 2007-2008 . ... Analysis of systematic errors based on CCD-observations taken with Normal Astrograph (D/F = 0.33 m/3.5 m, FOV = 18 16 arcmin, scale = 1 arcsec/pix) of Pulkovo observatory during 2007-2008 has been made. ... A statistical approach that used mean (O-C) values obtained for positions of reference stars within the field of view separated on square bins and magnitude ranges was applied. ...

... System of Works on Numerical Modeling of the Dynamics of the Structure of the Space Radiotelescope in the RadioAstron Project M. Yu. ... In particu lar, it is impossible to perform experimental modeling of a factor such as the operation of an antenna orientation pointing mechanism of a radio complex and its effect on the distortion of the SRT reflecting surface. ... Figure 7 presents the results of modeling the deviations of the platform of sensors while pointing the antenna of the radio complex. ...

TD-P20)< Nonlinear dynamics of hybrid Josephson junction with an oxide antiferromagnetic interlayer Karen Y. Constantinian, Gennady A. Ovsyannikov, Yulii V. Kislinski, Anton V. Shadrin, Igor V. Borisenko, Philippe V. Komissinskiy, Jesper Mygind and Dag Winkler Abstract-- Microwave dynamics of Nb/Au/CaSrCuO/YBaCuO hybrid Josephson junctions were studied under mm wave probe signals. Oscillating with microwave power integer and half-integer Shapiro steps were observed. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

Small Galaxy Groups ASP Conference Series, Vol. ... It is generally accepted that they are related to the nuclear rings formed in barred galaxies at the inner Linblad resonance (ILR), although according to Buta and Crocker (1993), in some cases they were found in non-barred spirals, so in general a presence of large-scale non-axisymmetric gravitational potential is not a rigid condition for the nuclear bar to be formed. Typical length of nuclear bars is 1 - 2 kpc for H 0 = 75km=s=Mpc. ...
