... High-velocity clouds (HVCs) were discovered by Muller, Oort & Raimond (1963) in the 21-cm line emission of neutral, atomic hydrogen. They are gas clouds which are characterised by high radial velocities incompatible with a participation in the rotation of our Galaxy. ... This suggestion was seized by Braun & Burton (1999) who identified 66 compact high-velocity clouds (CHVCs) with positional and kinematic characteristics being compatible with a distribution across the entire Local Group. ...

Top] [Prev] [Next] [Bottom] . The most efficient strategy for removing the background from a science exposure strongly depends on the nature of the target and of the science to be accomplished. ... For compact objects, such as point sources, background subtraction can be achieved by moving the target across the camera field of view (see Figure 10.1 ). ... In this case, offsets to an adjacent field (chopping), chosen to be at least one camera field away in an arbitrary direction, are necessary. ...

Time has come for me to move to a new longitude, but not before following the tradition and updating you on the work I have been doing in the latest stages of my PhD (and beyond). ... This presentation would of course not be complete without a final attempt at convincing you of the potential of some excitingly new technology to publish multi-dimensional datasets in 3-D. Hence, I shall also tell you about the newly developed X3D pathway Chris Owen and I have been developing lately. ...

Next: Other parameters of the Up: The Model Previous: Initial binary parameters . As we only deal with initially massive binary systems (their primary's mass is higher than 10 ), which are capable of evolving off the main sequence during less than years, the compact stars left behind stellar evolution are (in the case of the most massive stars) NSs and BHs. ... For a NS belonging to a binary, the evolution complicates as the secondary star evolves: for example, (recycling), etc. ...
