This model takes into account temperat ure distribution of sources and yields\nTsallis statistics for cosmic ray energy spectrum. Results are compared with the\nexperimental data.\n\nhttp s://indico.nucleares.unam.mx/event/4/session/41/contribution/848 LOCATION:Merida\, Mexico Uxmal + Tulum (Holiday Inn) URL:https://indico.nucleares.unam.mx/event/4/session/41/contribution/848 END:VEVENT BEGIN:VEVENT SUMMARY:Cosmic-Ray Origin and History Probed by GLAST: Gamma-Rays from St ar-Forming Galaxies DTSTART;VALUE=DATE-TIME:20070705T154200Z DTEND;VALUE=DATE-TIME:20070705T155400Z DTSTAMP;VALUE=DATE-TIME:20260517T033315Z UID:indico-contribution-41-1-1251@cern.ch DESCRIPTION:Speakers: Prof. FIELDS\, Brian (University of Illinois)\nGamma rays have long been recognized as a uniquely powerful probe of the existe nce\, origin\, and nature of cosmic \nrays beyond the solar system. The u nprecedented sensitivity and resolution of GLAST should for the first time \nconfirm the presence of cosmic rays in Local Group galaxies today\, and in all galaxies throughout the history of \ncosmic star formation. We sh ow that GLAST should detect\, with high confidence\, three Local Group gal axies: the \nLarge and Small Magellanic Clouds\, and M31. Observations o f their gamma-ray intensities will measure the cosmic-\nray flux within th ese galaxies\, and tests whether skupernovae are their dominant accelerato rs. Essentially all other \ngalaxies in the universe will be too dim for GLAST to detect individually\, but their collective emission will signific antly \ncontribute to the diffuse extragalactic gamma-ray background (EGRB ) seen by GLAST. This cosmic-ray component \nof the EGRB will have a uniq ue characteristic spectrum peaked around 0.5 GeV. GLAST measurements of t he \nintensity and spectral shape of this emission will probe cosmic ray h istory and should reflect the cosmic star-\nformation history in a well-de fined and testable way.\n\nhttps://indico.nucleares.unam.mx/event/4/sessio n/41/contribution/1251 LOCATION:Merida\, Mexico Uxmal + Tulum (Holiday Inn) URL:https://indico.nucleares.unam.mx/event/4/session/41/contribution/1251 END:VEVENT BEGIN:VEVENT SUMMARY:Numerical propagation of Cosmic Rays in the Galaxy DTSTART;VALUE=DATE-TIME:20070705T155400Z DTEND;VALUE=DATE-TIME:20070705T160600Z DTSTAMP;VALUE=DATE-TIME:20260517T033315Z UID:indico-contribution-41-1-736@cern.ch DESCRIPTION:Speakers: Dr. DE MARCO\, Daniel (Bartol Research Institute\, U niversity of Delaware)\nWe present a Monte-Carlo calculation of the propag ation of cosmic ray protons in the\nGalaxy for energies above 1 PeV. We di scuss the relative strengths of competing\neffects such as parallel/perpen dicular diffusion and drifts in toy models of the\nGalaxy. We compare our estimates with the results of the MC calculation for the toy\nmodels and t hen we apply the MC calculation to a few realistic models of the Galactic\ nmagnetic field. We study the containment times for different models of th e magnetic\nfield in order to understand which one is able to reproduce th e low energy data.\n\nhttps://indico.nucleares.unam.mx/event/4/session/41/ contribution/736 LOCATION:Merida\, Mexico Uxmal + Tulum (Holiday Inn) URL:https://indico.nucleares.unam.mx/event/4/session/41/contribution/736 END:VEVENT BEGIN:VEVENT SUMMARY:Propagation of High-Energy Cosmic Rays through the Galaxy: Discuss ion and Interpretation of TRACER Results DTSTART;VALUE=DATE-TIME:20070705T160600Z DTEND;VALUE=DATE-TIME:20070705T161800Z DTSTAMP;VALUE=DATE-TIME:20260517T033315Z UID:indico-contribution-41-1-1201@cern.ch DESCRIPTION:Speakers: Dr. BOYLE\, Patrick (University of Chicago)\nThe lon g-duration balloon flights of TRACER have provided new measurements of the \nintensities and energy spectra of the arriving cosmic-ray nuclei with 5 ≤ Z ≤ 26 at\nhigh energies. In order to determine the particle compos ition and energy spectra at\nthe cosmic-ray sources\, changes occurring du ring the interstellar propagation of\ncosmic rays must be known. We use a simple propagation model with energy-dependent\npathlength and derive con straints on the propagation parameters from a\nself-consistent fit to the measured energy spectra. We use the model to obtain the\nrelative abundan ces of the cosmic ray nuclei at the acceleration site and compare\nthese w ith the "universal" abundance scale.\n\nhttps://indico.nucleares.unam.mx/e vent/4/session/41/contribution/1201 LOCATION:Merida\, Mexico Uxmal + Tulum (Holiday Inn) URL:https://indico.nucleares.unam.mx/event/4/session/41/contribution/1201 END:VEVENT BEGIN:VEVENT SUMMARY:Magnetic Fields of the Milky Way DTSTART;VALUE=DATE-TIME:20070705T161800Z DTEND;VALUE=DATE-TIME:20070705T163000Z DTSTAMP;VALUE=DATE-TIME:20260517T033315Z UID:indico-contribution-41-1-1271@cern.ch DESCRIPTION:Speakers: Mr. JANSSON\, Ronnie (New York University)\nWe repor t on a project to constrain the large-scale and turbulent magnetic fields of\nthe Milky Way galaxy\, which eventually will incorporate all of the re levant\nobservational data. The initial work is based primarily on the WM AP3 polarization\nand intensity maps\, plus a large number of galactic and extragalact point source\nFaraday Rotation Measures. Preliminary results on the Galactic magnetic field are\npresented\, and consistency with UHEC R small-scale anisotropies is discussed.\n\nhttps://indico.nucleares.unam. mx/event/4/session/41/contribution/1271 LOCATION:Merida\, Mexico Uxmal + Tulum (Holiday Inn) URL:https://indico.nucleares.unam.mx/event/4/session/41/contribution/1271 END:VEVENT BEGIN:VEVENT SUMMARY:Galactic parameters expected from the current cosmic-ray data DTSTART;VALUE=DATE-TIME:20070705T163000Z DTEND;VALUE=DATE-TIME:20070705T164200Z DTSTAMP;VALUE=DATE-TIME:20260517T033315Z UID:indico-contribution-41-1-780@cern.ch DESCRIPTION:Speakers: Prof. SHIBATA\, Toru (Department of Physics and Math ematics\, Aoyama-Gakuin University)\nBased on the cosmic-ray (CR) data cur rently available\, we estimate the gas \ndensity\, diffusion coefficient\, and their spacial gradient in both the longitudinal \nand the latitudinal directions in the Galaxy. Applying our model on the three \ndimensional CR propagation for various CR observables such as stable nuclear \ncompone nts\, isotopes\, antiprotons\, diffuse gamma-rays\, we present analytical \nsolutions for them\, and give numerical results.

Assuming that the diffusion coeffici ent\nis of the form κ(E) = κ0(E/E0)^δ\, then for different optimal comb inations of κ0 and δ\nits value is obtained for cosmic rays originating from a central point (possibly Sgr\nA East) 10 kyr ago.\n\nhttps://indico. nucleares.unam.mx/event/4/session/41/contribution/1127 LOCATION:Merida\, Mexico Uxmal + Tulum (Holiday Inn) URL:https://indico.nucleares.unam.mx/event/4/session/41/contribution/1127 END:VEVENT END:VCALENDAR
