January 5th or January 12th

Hello everybody,

I know that the 5th is the day when most people will be back to work at IAP after the holidays.

However, attendance could still be low due to many and (un)expected side effects of the celebrations.

A quick poll could solve the problem: please send me an email at iocco@iap.fr only if you plan to attend the Cafe on january 5th; I will post an ad with the first 2009 Cafe date as soon as possible, and upload some papers.

Je vous souhaite une tres Bonne Nouvelle Annee!

Fabio

Café GReCO on Dec 15th

Here are a couple of papers I co-authored, which I may discuss:

*L. Pieri, A. Pizzella, E.M.Corsini, E. Dalla Bontà, F. Bertola

Could the Fermi-LAT detect gamma-rays from Dark Matter annihilations in the dwarf galaxies of the Local Group?

arXiv:0812.1494

*C. Giocoli, L. Pieri, G. Tormen, J. Moreno

A Merger Tree with Microsolar Mass Resolution: Application to gamma-ray Emission from Subhalo Population

arXiv:0811.2426

Also look at this paper:

*M. Cerdonio, R. De Pietri, Ph. Jetzer, M. Sereno

Local Dark Matter searches with LISA

arXiv:0811.4711

It would be very nice if somebody dealing with gravitational waves could make a very brief and informal introduction to GW and LISA.

-- I'd like to add the following paper, discussed yesterday with Martin
(see also the figure above for a visualization of the Milagro hotspot)

A. A. Abdo et al. (Milagro Collaboration), Phys. Rev. Lett. 101, 221101 (2008).

there is also a 'Viewpoint' discussion at

Angular correlations in the cosmic gamma-ray background from dark matter annihilation around intermediate-mass black hole

arXiv:0811.4493

M. Lattanzi, J. Silk

Can the WIMP annihilation boost factor be boosted by the Sommerfeld ehnancement?

arXiv:0812.0360

T. Jeltema, J. Kehayias, S. Profumo

Gamma Rays from Cluster of Galaxies: Cosmic Rays versus Dark Matter

arXiv:0812.0597

A. Boyarsky, J. Lesgourges, O. Ruchayskiy, M. Viel

arXiv:0812.0010

Carter-like constants of the motion

I can discuss this paper next Monday.

arXiv:0812.0110 [ps, pdf, other]
Title: Carter-like constants of the motion in Newtonian gravity and electrodynamics
Author: Clifford M. Will

Cafe GReCO, 1 December 2008

Today (1.30 pm in Salle du Conseil), we will discuss the
papers suggested by Lidia (arXiv: 0810.4995, Nature
Letters vol. 456 page 362 and arXiv: 0811.3894), along
with the (many!) papers on the possible intepretations
of the PAMELA data

http://arxiv.org/find/all/1/all:+pamela/0/1/0/all/0/1

We will also discuss arXiv:0810.2826 suggested by
Luc (see below).
