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 SourceA.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.)
