... On a possible reason of T c suppression with oxygen doping in Tl 2 Ba 2 CuO 6+x. Abstract: . Magnetic susceptibility and 63 Cu and 205 Tl nuclear spin-lattice relaxation rates have been measured in Tl 2 Ba 2 CuO 6+x high- temperature superconductor to establish the mechanism of decreasing the transition temperature with oxygen doping. The experiments have revealed the presence of localized paramagnetic centers (LPC) whose concentration grown with increasing oxygen content. ...

Apparent sporadic variations in the closed position of the two WFPC2 shutter blades were detected by examining the light reflected from the shutter in internal flats (INTFLATs). To characterize this phenomenon, we developed a simple algorithm to measure the history of the shutter jitter using INTFLATs. We found the position jitter in the direction of shutter motion to be minimal, indicating stable behavior. ...

Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

We have mapped the central region of the spiral galaxy NGC 1808 in the 12CO J=1-0, J=2-1, J=3-2 lines and measured 13CO J=1-0, J=2-1, C18O J=1-0, HCN J=1-0 and an upper limit on CS J=2-1 at the central position. ... The line intensity ratios indicate that the central molecular gas of NGC 1808 is in a state of high excitation compared with giant molecular clouds in the disk of the Milky Way. ... A simple estimate of the pressure felt by these clouds leads to further constrains on their properties. ...

Abstract -- Abundances of heavy elements decreases with increasing galactocentric distance almost in all disk galaxies. ... To explain this gradient in young objects and in the interstellar gas one has to assume that a typical disk galaxy is an open system, i.e. it expels some synthesized heavy elements into the circumgalactic space and/or accretes intergalactic gas with zero metallicity, with rates of both processes depending on the galactocentric distance. ...

We report 0.9-1.4um spectroscopic observations of NGC1068 collected during the commissioning phase of the near infrared camera spectrometer (NICS) of the Telescopio Nazionale Galileo (TNG). These yielded the first extragalactic measurement of PII (1.188um) line emission. In the central 0.75"x2" the FeII/PII line-intensity ratio is close to unity, similar to that measured in the Orion bar and a factor of . Mantained by: Leonardo Testi .
