Ohio Jan 2005 GRAVITATIONAL LENSING, DARK MATTER, AND DARK E

Post by Sarah Bridle » October 20 2004

Just got the below from John Beacom. Cool re remote participation!

----------------------------------------------------------------

FIRST ANNOUNCEMENT

GRAVITATIONAL LENSING, DARK MATTER, AND DARK ENERGY

January 5-7, 2005
Ohio Center for Theoretical Science
Ohio State University
Columbus, Ohio

----------------------------------------------------------------

"Gravitational Lensing, Dark Matter, and Dark Energy" will be
held at the Ohio Center for Theoretical Science (OCTS) at
The Ohio State University, from Wednesday, January 5, 2005 to
Friday, January 7, 2005. The venue will be the new
Physics Research Building at Ohio State. The primary conference
hotel, The Blackwell, is across the street on the campus of the
OSU Business School.

The goals of this workshop are to assess the current constraints
on the nature of dark matter and dark energy from strong and weak
gravitational lensing and gravitational microlensing, and to
assess the prospects for stronger constraints with the ambitious
surveys and instruments presently being planned or going into
operation. Specific topics include: models of dark matter and
dark energy, microlensing constraints on baryonic dark matter,
mass profiles of galaxies and clusters, evidence for dark matter
substructure, cosmic shear and galaxy-galaxy lensing as probes
of dark matter and dark energy, systematic uncertainties in
lensing measurements and their interpretation, wide-area imaging
surveys from the ground and from space, lensing of high-redshift
21cm emission and CMB anisotropies, and the interplay of lensing
and CMB constraints. A list of confirmed speakers appears below.

We have space for 80 participants, and we expect to have slots
for 12-15 contributed talks, complementing the program of invited
talks. Electronic registration will open November 1 via the OCTS
web page, http://octs.osu.edu. We strongly encourage registration
by November 15 in case there are more registrants than available
spaces; we will notify all registrants whether we have space and a
contributed talk slot (if one was requested) by November 17.
The registration fee will be $100, including lunch on all three
days. If you have questions that are not answered on the web page,
please send email to the OCTS Director, Steve Pinsky
([Log in to view email]), and to the Organizing Committee Chair,
David Weinberg ([Log in to view email]).

This workshop is the second in a series of workshops offered by
the OCTS. A unique feature of these workshops is that they are
broadcast on an interactive network using Access Grid technology.
If you have an Access Grid facility at or near your institution,
you can see all of the workshop talks, be a full participant in
all discussions, and present a talk remotely. We strongly
encourage this form of participation and will be happy to assist
with practical arrangements. There is no registration fee for
remote participants, and no limit on the number of remote
participants. There are currently over 200 access grid
installations, and you can check to see if there is one near you
at http://www.accessgrid.org/community/nodes/nodes.html.
Anyone interested in participating over the Access Grid should
contact Kendra Davitt ([Log in to view email]).

The current list of confirmed speakers is

Gary Bernstein University of Pennsylvania
Robert Caldwell Dartmouth College
Neal Dalal Institute for Advanced Study
Scott Dodelson Fermilab/University of Chicago
Richard Ellis California Institute of Technology
Joshua Frieman Fermilab/University of Chicago
Michael Gladders Carnegie Observatories
Kim Griest University of California, San Diego
Henk Hoekstra^* University of Victoria
Daniel Holz Los Alamos National Laboratory
Bhuvnesh Jain University of Pennsylvania
Marc Kamionkowski California Institute of Technology
Tim McKay University of Michigan
Brice Menard Institute for Advanced Study
Priya Natarajan Yale University
Ue-Li Pen Canadian Institute for Theoretical Astrophysics
David Sand California Institute of Technology
Martin White University of California, Berkeley

^* Remote talk from University of Victoria.


The Scientific Organizing Committee is:
John Beacom, Andrew Gould, Christopher Kochanek,
Jordi Miralda-Escude, Barbara Ryden, Gary Steigman,
Terry Walker, and David Weinberg

The remote participation went ahead yesterday as advertised.

I installed AccessGrid Toolkit 2.2 on my laptop (running Windows XP) from http://www-unix.mcs.anl.gov/fl/research ... /user.html and had to send off for a certificate which arrived by email shortly after. Then was able to join the meeting.

Because I was running from my laptop on the standard university network (rather than a proper AccessGrid setup) I had to change the setting from "Use multicast" to "Use unicast", which seems to mean that I could join in the audio (send and receive realtime) but could not see (or send) the video.

So I could hear the talks, and also follow along using the powerpoint which was online. So I did find it really interesting and useful. Thanks v much for setting it up!

Was wondering whether this or other software could be used for live journal clubs in the near future. I guess would want to be able to run from the computers on people's desks using standard (not multicast?) network connections. Has anyone got this working with several people communicating at once? If so what software?

Also, several people were wondering if there could be a live "chat" element to cosmocoffee. Any suggestions/comments v welcome. Yesterday jabber chat was being used and it looked quite good.
