... Research . ... The major problem in HVC research is the unknown distance towards most of the HVCs. ... Thilker et al. (2004) used the Green Bank Telescope (GBT) to map an area of $7^{\circ} \times 7^{\circ}$ around M31 in H i . They discovered a population of HVCs located within a projected distance of about $50~\mathrm{kpc}$ from M31. ... 2004). ... The remaining HVCs around M31 are isolated in position and velocity and may represent primordial, dark-matter-dominated clouds. ...

From: TerryMosel@aol.com Date: Thu, 21 Nov 2002 17:26:38 EST Subject: LEONIDS Lecture Hi all, Sorry I couldn't reply sooner - I was off giving a lecture to NUI Maynooth, followed by a visit to LoughCrew. ... There was an apparently equal number of fainter meteors down to the limiting magnitude although the bright moonlight could have hidden many more. ... The peak of activity did occur around 04:00, in line with predictions, with peak bursts of around one Leonid per second. ... Terry Moseley . ...

Some 13.7 billion years ago, a mere millionth of a second after the Big Bang, the first hydrogen and helium nuclei condensed out of a hot, dense soup of quarks and gluons. ... In the very last few kilometres some of the light was scattered by a myriad of water droplets (containing hydrogen nuclei which had existed almost since the Big Bang) slowly descending through the air following a rainshower. ...

The near-IR data from 2MASS (Two Micron All Sky Survey) and DENIS (Deep Near-Infrared Southern Sky Survey) are ideally suited for studies of the structure of the LMC, because of the large statistics and insensitivity to dust absorption. ...
