... Introduction In a proposal funded by the ATNF, the University of Queensland and the Uni- versity of Bonn, the ATNF has now developed a narrow-band back-end system for the Parkes Multi-Beam system. The project has provided a narrow-band back-end lter and correlation- system able to use the inner 7-beams of the multi-beam system for observations of spectral lines over 2048 channels with a total bandwidth across each spectrum of either 4 or 8 MHz. ...

... The Si VIII line width measurements and N e estimates based on SUMER observations are combined with LASCO and UVCS output to provide an overview of its variations with height above a polar coronal hole. ... Combining the Si VIII half width at 1/e of the peak intensity with the UVCS O VI half width, we find a small increase of the half width from 1 to 1.2 , then a plateau until 1.5 , thereafter a sharp increase until 2 , finally a more gradual increase reaching 550 km s -1 at 3.5 . ...

... It is notoriously difficult to identify weak cosmic ray events in long exposure observations. ... The method is to compare the probability distribution function (PDF) of cosmic ray events between an observation and a dark frame matched in exposure time. We illustrate the basic idea using dark exposures from a Tek 1024 1024 CCD with varying exposure lengths and read-out times. ... Figure: Histogram of cosmic ray events in a two hour dark frame. ...

Marc White . ... Turbulent entrainment processes may play an important role in the outflows from young stellar objects at all stages of their evolution. In particular, lateral entrainment of ambient material by high-velocity, well-collimated protostellar jets may be the cause of the multiple emission-line velocity components observed in the microjet-scale outflows driven by classical T Tauri stars. ...
