IAU Symposium No.230: 1st Announcement

                                                                              
Dear Colleague,
                                                 

At its meeting in Mexico City on 25 May 2004, the Executive Committee
of the International Astronomical Union accepted the proposal for an
IAU Symposium on  "Populations of High-Energy Sources in Galaxies", 
to be held 15-19 August 2005 in Dublin, Ireland. This will be IAU 
Symposium No. 230. The venue will be Dublin Castle, in the centre of 
town. 
                                               

With currently operational high-energy satellite observatories the 
potential for conducting detailed studies of individual sources of 
high-energy radiation in other galaxies as well as in our own Milky Way 
has greatly increased.

The primary objectives for this Symposium are: 
* Overview of key source categories in our Galaxy (X-ray and gamma-ray, 
  the latter notably referring to INTEGRAL results) 
* Review of the results on individual high-energy sources in 
  galaxies that have been obtained with Chandra and XMM-Newton 
* Derivation of global descriptions of high-energy source 
  populations in galaxies 
* Assessment of the evolutionary status of stellar populations, 
  derived from the X-ray investigations 
* Discussion of the high-redshift context of the source populations
 

Information on IAU Symposium number 230 is available via

The anticipated time timetable is: 
       October  2004 :  1st Announcement
    15 December 2004 :  deadline for pre-registration 
       January  2005 :  2nd Announcement
       April    2005 :  Final Announcement
     1 June     2005 :  Registration Deadline
    15 August   2005 :  Symposium programme starts 
    
The purpose of the pre-registration is to gauge the interest in this 
Symposium, so as to assist SOC and LOC with their organization. 
The 2nd Announcement will contain the call for registration, information 
about hotel reservations, abstract submission, posters, proceedings, 
IAU travel grants, invited speakers and sponsorship. 


Please circulate this 1st Announcement in your Institute or University 
Department and to colleagues elsewhere that may be interested. We try 
to avoid this notice being sent more than once to you, but occasionally 
your e-mail address might occur in more than one of our mailing lists.
