        The 9th Birmingham-Nottingham Extragalactic Workshop 

                 Substructure in Dark Matter Halos

                          July 6-7th 2006

                         Third Announcement

                  www.sr.bham.ac.uk/workshop/2006


The Birmingham-Nottingham Workshops are informal 2-day events held each
summer, with the aim of bringing together observation and theory in a
topical and well-focussed area of extragalactic astronomy.

This year's topic is substructure in dark matter halos, spanning the local
group through to the most massive galaxy clusters.  Further details of the
scientific motivation are given below.

The workshop, involving ~50 participants, will be the 9th in the series.  
The format will include a mixture of 15 and 30 minute talks, leaving
plenty of time for discussion.

We will start at 11am on July 6th and conclude at around 4pm on the 7th.  
Please let us know if you would like to attend (an email form is attached
below).  If you are interested in giving a talk, please send us your
title.

The workshop fee will be £45 per participant.  This includes two lunches
and a traditional Birmingham gastronomic feast (Balti) on the Thursday
evening.

Accommodation is available in local hotels/B+Bs (see workshop web-site for
more details).  Our block of pre-reserved rooms on campus at Lucas House
is now full.

To register, simply complete the form below and email it to
workshop@star.sr.bham.ac.uk.  We have extended the registration deadline
to June 30th.

Please forward this email to anyone else you think may be interested.

We look forward to seeing you at the workshop.

        The 9th Birmingham-Nottingham Extragalactic Workshop 

                 Substructure in Dark Matter Halos

                      Scientific Motivation

The cold dark matter (CDM) model reproduces well the observed large scale
structure of the local universe, however on smaller scales non-linear
collapse of dark matter halos and the presence of baryons complicate the
picture severely. How does the hierarchical assembly of dark matter halos
modify the galaxies and gas trapped in those halos?  What is the
relationship between baryonic structures, and the underlying substructure
of dark matter halos?  Is the substructure of dark matter halos consistent
with CDM?  This Workshop will address these questions, emphasising the
relationship between dark and luminous substructure.

Much observational progress has been made in recent years in the
multi-wavelength/technique study of substructures within dark matter halos
spanning the local group, through massive galaxies and their group
environments, to the most massive galaxy clusters.  We aim to discuss
these results and their interpretation, and to identify the important open
questions.  Looking forward, we therefore anticipate lively discussion
including:

* "what questions should we ask of the latest (and future?) generation of
  theoretical simulations and models?" and; 

* "what challenges might new observational surveys face when comparing new
  samples of more distant objects with their 'local' counterparts?". 

The Birmingham-Nottingham Extragalactic Workshops typically involve ~50
participants. This year's meeting will be held in the School of Physics &
Astronomy at the University of Birmingham. The format will comprise a
mixture of 15 and 30 minute talks, with plenty of time for discussion.

Confirmed speakers from outside Birmingham include:
 Mike Irwin, Leon Koopmans, Liang Gao, Pasquale Mazzotta, Scott Kay,
 Alexis Finoguenov, Eric Hayashi, Jordi Barr, Ray Sharples, Eduardo 
 Cypriano, Pasquale Mazzotta, Chris Collins, Noam Libeskind, Matteo 
 Barnabe, Edo Noordermeer, Davor Krajnovic, Steve Phillipps, Simona
 Vegetti, Anne Green
