ASTROVIRTEL: Third Call for Proposals (fwd)
by boud 13 Apr '02

13 Apr '02

I don't think we're ready for this yet, but feel free to think about this. If anyone can think of a project, go ahead and write your thoughts to the list - be creative! And don't worry about your ideas being crazy. Starting off from a crazy idea and playing with it can often yield a good idea... Which is better than no ideas at all... > ---------- Forwarded message ---------- > Date: Fri, 12 Apr 2002 12:26:20 +0200 (MET DST) > From: AstroVirtel User <astrov at eso.org> > To: boud.roukema@... > X-SBFolder: Default > X-SBClass: OK > Subject: ASTROVIRTEL: Third Call for Proposals > > > Dear Colleague, > > The ASTROVIRTEL Project, supported by the European Commission > and managed by the ST-ECF on behalf of ESA and ESO, is aimed > at enhancing the scientific return of the ST-ECF/ESO Archive. > It offers the possibility to European Users to exploit it as > a virtual telescope, retrieving and analysing large quantities > of data with the assistance of archive operators and scientific > personnel.

Another confirmation of the existence of dark energy.

----- Forwarded message from NewsAlert ----- NEWSALERT: Friday, March 22, 2002 @ 1504 GMT --------------------------------------------------------------------- The latest news from Astronomy Now and Spaceflight Now [...] NEW EVIDENCE: EXPANSION OF UNIVERSE IS ACCELERATING --------------------------------------------------- A team of UK and Australian astronomers has discovered new, independent evidence that the expansion of the universe is accelerating. Their findings have just appeared in the Monthly Notices of the Royal Astronomical Society. A team of 27 astronomers led by Professor George Efstathiou of the University of Cambridge has published strong evidence for the existence of dark energy using an entirely different technique. Their results show that the universe is full of dark energy, completely consistent with the earlier supernovae results. "Dark energy appears to exist and to dominate over more conventional types of matter" says Professor Efstathiou. "An explanation of the dark energy may involve String Theory, extra dimensions or even what happened before the Big Bang. At present nobody knows. The ball is now firmly in the theorists court." http://spaceflightnow.com/news/n0203/22expansion/ [...] ----- End of forwarded message from NewsAlert ----- -- Andrzej Marecki

2 observation-linked galaxy projects (long term)
by Boud Roukema 03 Apr '02

03 Apr '02

Hi. I'm just sending this message to have it conveniently on the archive with an obvious "Subject:" header. I think I've already mentioned these two projects (or themes) which are linked to local observational facilities: (1) polarisation of radio-galaxies Ryszard Wielebi�ski of Bonn suggested that a good way to use the radio telescope here would be to observe galaxies at different frequencies, so with different amounts of Faraday rotation of polarised light, so that the polarisation could be inferred. (2) galaxy formation modelling in preparation for future infrared satellite data Ryszard Szczerba said something about NCAC being involved in an infrared satellite project (I think I got the name wrong - Ryszard, do you have a link to the web site of the project?), so if someone does some galaxy formation work in preparation for this, there would be a good chance of getting good observational constraints, and maybe even falsifying some models, and having to generate new ones, which is the exciting part of science :). Cze�� Boud Ryszard: this email will be archived on http://www.astro.uni.torun.pl/sympa/cosmo-torun/ Please reply directly to the list (unless you have something secret to say).
