... About ATNF overview . ... Australia Telescope Steering Committee . ... LMC H II Region Luminosities versus . Observed Ionizing Stars . ... These values are compared to the observed H II region luminosities, yielding an estimate for the mean fraction of H-ionizing photons that escape the local nebulae in this sample. We formally estimate that, overall, 0-51% of the ionizing radiation escapes the local H II regions and is available to ionize the warm, ionized medium in the LMC. ...

... Magnetic resonant mode in the single-layer high-temperature superconductor Tl 2 Ba 2 CuO 6+x. Abstract: . ... The mode has thus far only been observed in materials with crystal structures consisting of copper oxide bilayers, and it is absent in the single-layer compound La 2-x Sr x CuO 4+x . ... This restricts the theoretical models for the origin of the resonant mode and its role in the mechanism of high temperature superconductivity. ...

... We study the variation of the line width and electron density as a function of height above two coronal holes from forbidden spectral lines of Si VIII. The spectra were obtained with the Solar Ultraviolet Measurements of Emitted Radiation spectrometer flown on the Solar and Heliospheric Observatory spacecraft. ... The electron density shows a decrease from 1.1 10 8 cm -3 to 1.6 10 7 cm -3 over the same distance. ...

... Science Activities > PhD Thesis Topics offered by ESO Faculty Members > Thesis Topic: The role of magnetic fields in the intermediate-mass star formation process . ... Spectropolarimetric observations of Herbig Ae/Be stars indicate that magnetic fields are important ingredients of intermediate mass star formation. To properly understand the physics involved in the intermediate mass star formation process, it is particularly important to know the origin of the magnetic fields in these stars. ...

... Previous: Residual Bias Removal in HST NICMOS Images . ... Bias frames taken with CCDs should be homogeneous in intensity. ... Using a large number of bias frames obtained in one specific run, the time-dependent pattern was found to be built up of a fixed one-dimensional periodic function whose phase-shift varies from row to row. It was successfully removed from calibration and science frames through the use of pre- and upscan ``bias'' pixels available in each of these frames. ...
