Large Scale Reconstruction 2004 (LSR2004)

Observatoire de la Côte d'Azur, Nice, France, August 30 to September 3, 2004.

This worskhop will be devoted to methods of reconstruction of the dynamical history of the Universe and of the present peculiar velocities from the present positions and luminosities/masses of the baryonic matter. The workshop will be centered on comparison and bridging of two broad classes of methods: the Numerical Least Action method originating with the work of P.J.E. Peebles and the recent Monge-Ampère-Kantorovich method developed at the Observatoire de la Côte d'Azur. The emphasis will be on numerical techniques, algorithms and recent applications to observational data.

Organizing Committee: U. Frisch, R. Mohayaee, A. Sobolevskii, B. Tully

This workshop is made possible by support from the French Ministry of Education, CNRS Programme National de Cosmologie, and the Laboratoire Cassiopée

This is the second in a series of two related workshops; for info on the first one, click this link: Stellar Content and Distances of Nearby Galaxies 2004

List of participants

The emails are given with a French-flavoured anti-spam precaution: AROBASQUE stands for the "at" sign, and POINT of course means "dot."

Venue

The programme will be taking place at the Nice site of the Observatoire de la Côte d'Azur, mostly in the meeting room next to the library (Pavillon Henri Chrétien). General information on the Observatoire is available here and here (in French).

Survival hints

Getting to the Observatoire

From Best Western Hotel Nautica: Turn right as you come out of the hotel and follow rue Barberis two blocks until you come to rue Arson, then turn left and follow three blocks to place August Blanqui, where you take the minibus 74 to the Observatoire. See the schedule of bus 74 below.

Note that one can walk up from Gare Riquier to the Observatoire by a nice and steep path in 40 to 90 min depending on your shape (ask a knowledgeable person to show you the first time: not so easy to find).

The schedule of bus 74

Departure from Gare Riquier (NB on Thursday and Friday the schedule changes, which is marked in italics):
6:50, 7:20, 8:10, 8:45, 9:15, 10:10, 11:20, 12:05, 13:10, 14:00, 15:00, 15:50, 16:30, 17:30 (17:35), 18:10 (18:00), 18:50 (18:30 and 19:00), 19:30

To get to the Observatory before the morning session starts, you should use buses at 8:45 and 9:15. To get to the Observatory by the lunch time, the only suitable bus is at 11:20.

Departure from the Observatory:
The bus makes a loop, so on each trip it passes the Observatory once and then takes a different route to the city. To return to the city by bus, you thus should come to the Observatory stop at the time the bus passes it, i.e. in approximately 10 minutes after its departure from Gare Riquier. It is of course a good idea to come to the stop a few minutes earlier.

Telephone

To call an observatory telephone from outside, dial 04 92 00 ## ##, where ## ## is a four-digit extension inside the observatory.

For local calls outside the observatory, dial 0 first, then the ten-digit French telephone number. For long-distance and foreign calls please ask a local participant who will give you a suitable code (somewhat confidential). Please note that you cannot call mobile phones from observatory fixed phones.

Local computer network

There are several Linux PCs and X terminals with guest accounts available for participants (details of their location and access procedures are better explained on the spot rather than in an abstract text like this). The Observatory is now running DHCP, so you can connect your laptops to the network. There is no wireless network on the site.
