The wealth of new information through observations has led to a flourishing development in theoretical modelling. The purpose of this conference is to summarize relevant observational results at all wavelengths, to compare the predictions of models and simulations to these observations, and to assess the impact of processes in cluster cores on the application of galaxy clusters as cosmological probes. All further relevant information has been posted at the conference web page ******************************************* * http://www.astro.virginia.edu/coolflow/ * ******************************************* If you are potentially interested please take a short moment to fill in the pre-registration form to ensure receiving future announcements. We apologize if you received this Announcement more than once.

In-Reply-To: <200203251359.OAA25475@galileo.astro.uni.torun.pl> Message-ID: Hi again Andrzej, : Yes, it's on http://www.ras.org.uk/press/pn02-06.htm and this is IMO : absolutely OK (whoever stands behind RAS). This is IMHO *not* making : propaganda - I'm sure that there are members of RAS among those 27 people : listed in the masthead of the MNRAS article so RAS has a right to "be : proud" of them and their publication in RAS's own journal and so RAS has a : right to issue a press release on *their* website. By the same token we : we have a right prepare press releases on ours. I agree that it's more or less OK and that the RAS certainly has a right to publicise the results from MNRAS articles. However, although they do not *state* that they have the first non-SNe-Ia evidence for a non-zero cosmo constant, their omission of any reference to totally independent results, such as our own, but also others (e.g. weak grav lensing), makes it easy for the non-expert (and/or non-alert) reader to falsely conclude that it *is* the first. Instead of: > ... and many > have been reluctant to accept the > results of the supernovae teams. > > Now, 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.

Wouldn't this have been more honest? : This is IMHO *not* making : propaganda Edward Bernays is to the public relations industry something like what Einstein, de Sitter, Friedmann, Lemaitre, et al are to modern cosmology. Bernays' basic 1928 book on the subject was called "Propaganda". http://www.authentic-breathing.com/propaganda_in_a_democracy.htm > When Edward Bernays, proclaimed by many as the father of public > relations, published his book Propaganda in 1928, few people realized > the far reaching influence that the new discipline of public relations > would have on society.

You had some other comments: > Why spaceflightnow.com reposts RAS PRs? - is a good question. Ah well, I think that's way beyond the scope of what I have time to study quantitatively. But my guess is that it's related to propaganda/advertising in the West in general: http://www.zmag.org/chomsky/articles/z9710-mainstream-media.html > Would spaceflightnow.com repost TCfA PRs? - is even a better question. :-) Well, I don't know about spaceflightnow.com in particular, but since our research work does not directly threaten any large authoritarian corporations or authoritarian governments or democratic governments, except indirectly because it shows that people in a non-US/UK country do good science, I think that if one or more people were willing to spend the time talking to journalists and explaining stuff to them, e.g. via cosmo-media, then there's actually a fairly good chance they would publish stuff. E.g., you would be most welcome to use cosmo-media to prepare a press release on your young radio galaxy results. You could prepare a draft on the list - and do both po polsku and English versions, but ask journalists to wait until the article is accepted before they use the press release. But it would be a good idea to ask a journalist to work through it with you - and IMHO it would require work... It takes time and thought to explain things to non-astronomers - or even to astronomers ;) ... One idea for reducing the amount of work and making sure the article is easily understandable - and for getting publicity to people who really *do* want to know what we're doing, who do *not* just want to blindly learn how to repeat words and sentences which are useful for making polite conversation and sounding educated - would be to invite readers of the Usenet group: http://groups.google.com.pl/groups?hl=pl&group=pl.sci.kosmos to comment and criticise and draft versions of the press release. A question to be debated would be whether we want Usenet readers to subscribe and/or post to cosmo-media or to keep the discussion to pl.sci.kosmos. My preference would be the latter.

But... although I have no interest in defending RAS I think it is always honest to tend to narrow down the responsibility to particular persons. In this case the person to blame is the *referee* who allowed the authors to ommit the reference(s) to other groups work. Now the good question emerges: who on Earth wrote that $&%@ PR??!!!

IMO the best way to show that is... to publish in US/UK journals. If Roukema, Mamon & Bajtlik paper were published in MNRAS and not in A&A then maybe... ;-) But OK, you're right, we have to talk to journalists and explain things to them. Preferably we have to talk to US/UK journalists... Because if we talk e.g. to Polish journalists then there is hardly any impact. Example: recently Udalski et al. discovered a few dozens of extraterrestrial plants in "one go". There was a large (front page) coverage of this discovery in the largest Polish daily newspaper. Now how about spaceflightnow.com et al.? NOTHING! So maybe there *is* an Anglo-American mafia censorship. But maybe not. If only Udalski et al. published in ApJ or MNRAS and not in Acta Astronomica.... :-) -- Andrzej From amr w astro.uni.torun.pl Tue Mar 26 13:33:56 2002 From: amr w astro.uni.torun.pl (Andrzej Marecki) Date: Tue, 26 Mar 2002 13:33:56 +0100 (MET) Subject: Another confirmation of the existence of dark energy.

I think this could be an important paper for modelling what statistical constraints on Omega_m & Omega_Lambda (or eventually w_Q) could be obtained from OCRA.

But they need to justify their funding under the Rupert Murdoch/IMF/WTO/WB media/political regime which opposes rational discussion and balanced publication of empirical data... So we can't really blame them for struggling for survival! And nothing seems to be incorrect in the RAS news release, it is just misleading by omission - which is a perfectly standard method of propaganda in democracies. (See http://www.medialens.org or http://www.mwaw.org for media criticism from the heart of what's left of Her Majesty's Empire.) Anyways, here's the article: http://de.arXiv.org/abs/astro-ph/0109152 "Evidence for a non-zero Lambda and a low matter density from a combined analysis of the 2dF Galaxy Redshift Survey and Cosmic Microwave Background Anisotropies" They don't even bother to cite the paper based on the 2dF *quasar* z survey, posted three months earlier: http://de.arXiv.org/abs/astro-ph/0106135 which has evidence for a non-zero Lambda and a low matter density from analysis of a *single* survey, the 2QZ-10K early release. Gary Mamon thinks we should spend some time in making propaganda, sorry, "media relations", for our result, but I think it's better to concentrate on getting new results which cannot be ignored. ;) And then the best way for a propaganda campaign, sorry, for public relations, will be to release a GNU/Linux self-contained easy-to-compile and run software package which any cosmologist can easily run for herself and be convinced of the results... BTW, Efstathiou et al. use maximum likelihood, which means, if I understand it correctly, that they really only show that a non-zero Lambda, low Omega_m model is *more* likely than other models, they don't reject a zero-Lambda model. In contrast, we use absolute probabilities of null hypothesis rejection, so we *do* reject the zero-Lambda model and high matter density models.

Hi Andrzej, I agree with the idea of writing to them, but if we're going to spend time on this sort of thing, then in order to minimise wasted energy and avoid misunderstandings - or at least have a public record of media relations - it would be good to have a dedicated mailing list. There might be very few subscribers, but the important thing is to have the archive. (I had this sort of idea earlier when Ken Grimes and Alison Boyle asked about topology, but didn't think the question would come up again this quickly.) So... could you please create the following list, with a configuration similar to the others (no access restrictions): ---------------------------------------------------------------------- name: cosmo-media purpose (short): For openness in interactions between TCfA cosmologists (including students) and science journalists, either as subscribers or using cc: copies. purpose (long): This list is for discussions with the media on cosmology research results. Suggested usage is to cc: messages to the media to this list, so that they know that the emails are on the public record. Science journalists could choose to subscribe to the list, or else to email to the list as non-subscribers and send confirming emails each time. Any TCfA cosmology people - including students - wishing to discuss with the media should feel welcome to use and cc: to the list. ---------------------------------------------------------------------- Any comments, anyone, on the suggested definition of the list? BTW: I'm confused about your earlier message (but I'm restricting the thread to cosmo-torun, I don't think it's interesting enough for all Polish cosmologists ;) ...).

Yes, it's on http://www.ras.org.uk/press/pn02-06.htm and this is IMO absolutely OK (whoever stands behind RAS). This is IMHO *not* making propaganda - I'm sure that there are members of RAS among those 27 people listed in the masthead of the MNRAS article so RAS has a right to "be proud" of them and their publication in RAS's own journal and so RAS has a right to issue a press release on *their* website.
