cds-question@unistra.frgalaxiesstellar-distanceastronomical-modelsGamma-ray searches for dark matter annihilation and decay in dwarf galaxies rely on an understanding of the dark matter density profiles of these systems. Conversely, uncertainties in these density profiles propagate into the derived particle physics limits as systematic errors. In this paper we quantify the expected dark matter signal from 20 Milky Way dwarfs using a uniform analysis of the most recent stellar-kinematic data available. Assuming that the observed stellar populations are equilibrium tracers of spherically symmetric gravitational potentials that are dominated by dark matter, we find that current stellar-kinematic data can predict the amplitudes of annihilation signals to within a factor of a few for the ultra-faint dwarfs of greatest interest. On the other hand, the expected signal from several classical dwarfs (with high-quality observations of large numbers of member stars) can be localized to the ~20% level. These results are important for designing maximally sensitive searches in current and future experiments using space and ground-based instruments.2015ApJ...801...74Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/801/74CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/209/22 : SSDF survey: IRAC catalogs (Ashby+, 2013)J/ApJ/770/16 : Spectroscopic members of Segue 2 galaxy (Kirby+, 2013)J/ApJ/756/79 : Optical phot. in 3 Local Group dwarf galaxies (Sand+, 2012)J/AJ/144/4 : Dwarf galaxies in the Local Group (McConnachie+, 2012)J/MNRAS/418/1526 : Dark matter in dSph galaxies (Charbonnier+, 2011)J/ApJ/736/146 : Radial velocities of stars in Bootes I (Koposov+, 2011)J/ApJ/733/46 : Velocity measurements in Segue 1 (Simon+, 2011)J/ApJ/718/530 : Leo IV g- and r-band photometry (Sand+, 2010)J/ApJ/710/1664 : BV photometry in Leo IV and Leo V dSphs (de Jong+, 2010)J/MNRAS/397/1748 : Spectroscopic study of Segue 2 (Belokurov+, 2009)J/ApJ/694/L144 : Spectroscopic study of Leo V dSph (Walker+, 2009)J/ApJ/692/1464 : Spectroscopy of Segue 1 (Geha+, 2009)J/AJ/137/3100 : Radial velocities of 4 dSph galaxies (Walker+, 2009)J/ApJ/675/201 : Radial velocities of stars near Leo I (Mateo+, 2008)J/ApJ/663/960 : Radial velocities of Leo I stars (Sohn+, 2007)J/MNRAS/330/792 : Radial velocity in Draco (Kleyna+, 2002)J/AJ/113/634 : The survival of Sagittarius dwarf galaxy (Ibata+ 1997)http://fermi.gsfc.nasa.gov/ssc/data/analysis : Fermi Science Support Centerhttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/801/74https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/801/74http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/801/74https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/801/74https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/801/74http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/801/74GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/801/74/sat (Properties of Milky Way satellites, stellar-kinematic samples and halo profile parameter constraints)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/801/74/sat?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/801/74/sat?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/801/74/sat?GETtext/xml+votable180.050000true100.402917-50.9661110.0055555555555555566/619 4410 4419 6021 7416 8745 10183 10444 10769 11691 26980 27000 27207 27580 28136 28361 31692 35720 35969 39100https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/801/74?format=asciidefaultJ/ApJ/801/74/satProperties of Milky Way satellites, stellar-kinematic samples and halo profile parameter constraintsSimbadNameSimbad column added by the CDSmeta.idcharalpha[1.4/2.2] Median {alpha} (1)stat.fit.paramfloatgamma-1The -1{sigma} constraint on gamma (G1)stat.errorfloate_Rh[3/77] Negative error on Rhpcstat.errorintrecnoRecord number assigned by the VizieR team.
