Comments on the case for high time resolution science Mike Redfern Mon, 28 Apr 2003 -------------------------------------------------------------------- It is a new, and not mature, field so we are just now finding out about things. There is a considerable community and I suggest that we should generate the science case that you need - this includes myself and others here in Galway Harlaftis in Athens Phil Charles et al in Soton Stefan Wagner in Heidleberg Dainis Dravins in Lund Vik Dhillon in Sheffield Gottfried Kanbach in MPI Christian Gouiffes in Saclay The evidence is that some classes of object are variable on every timescale (i.e. there is no characteristic timescale apparent, new information is available on every timescale, and the shortest timescales have been limited by photon statistics/SNR considerations) - variablity is apparent in flux, spectrum & polarisation These include some types of AGNs, compact objects (inner accretion disk and magnetospheric emssion), and many others In addition, very large photon fluxes may allow high order correlations to be investigated - in this respect ELTs may be millions of times better than current telescopes Please come back to me if you want me to nominate members of this group to generate what you need.
