... 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. ...

... Polar Cap Potential . ... The solar wind propagation delay time calculation used here is conceptually similar to the T(IMF) calculation in Kelly, et al. ... The older continuous data are from key parameter data files. ... Note: Very high values of Solar Wind Speed, Solar Wind Pressure, IMF Magnitude and Bz, and Polar Cap Potential are likely indications that WIND has reentered the Earth's magnetosphere; such data is not indicative of solar wind conditions or impending severe geomagnetic disruption. ...

... Research . ... I aim to understand the variety of processes that have driven galaxy formation and mass assembly across cosmological history via the resolved (star-by-star) study of nearby systems - in particular the Milky Way and Andromeda (especially their stellar halos and globular cluster populations), the Magellanic Clouds, and the myriad of smaller dwarfs that inhabit the "Local Group".б  . ... Globular clusters are fascinating objects in their own right. ...

... More recently, I have been concerned with observing masers located in the circumstellar shells generated by red giant stars in their mass-loss phase, and in what we can therefore learn about the late stages of stellar evolution. 100 mJy are now undetectable after ~12 years, aka the DEATH of an OH/IR star or its cyclical evolution back to a Mira variable. ... I find that this momentum flux is sufficient to support the largest observed rates of AGB mass-loss. last updated: 14 January 2015 . ...
