Plans for Papers Papers in process, papers planned for the next year, paper ideas for year 1 of operations; which are proposed to be Category 1 and which are Category 2; Currently most papers planned for pre - launch, clearly not using GLAST data, will be category II (III) papers. A number have already been published. Search for Supersymmetric Dark Matter with GLAST A.Morselli, A.Lionetto, A.Cesarini, F.Fucito, P.Ullio, Nucl. Phy. B 122B (2003) 413-416 The Galactic Center as a Dark Matter Gamma-Ray Source A.Cesarini, F.Fucito, A.Lionetto, A.Morselli, P.Ullio, Astrop. Phy. 267-285 Multifrequency analysis of neutralino dark matter annihilation in Coma cluster, S.Colafrancesco, S.Profumo, P.Ullio, Astro-ph/0507575 Diffuse inverse Compton and synchrotron emission from dark matter annihilations in galactic satellites. T. Baltz, L. Wai, Phys.Rev. D70 (2004) 023512 Repeat De Boer’s paper with large group of LAT collaborators. Astro-ph/0412620 v1 23 Dec 2004, “Indirect Evidence for WIMP Annihilation from Diffuse Galactic Gamma Rays” Possible category I is extensive and careful study of DM limits from all known experiments as a precursor to launch and what kind of limits GLAST can set. After launch during 1st year paper on DM limits set by GLAST using pre-launch paper as a guide.

Plans for the near future: for the end of September : • Provide to the MultiWavelengh group the MW need of our group overlap with other groups: we will define interface persons ( that will participate to other groups ) and they will notify news from that groups. We need interface persons at least for : Diffuse (Galactic & Extragalactic) and Molecular Clouds Larry Way Unidentified Sources, Population Studies, and Other Galaxies TBD Gamma-Ray Bursts Nicola Giglietto Catalogs TBD • Checkout 3: "test WIMP clump" at high latitude (1month "practice" data including 3rd egret catalog, diffuse, etc.)
