Astrophysical explanations of suspected dark matter signals in dwarf galaxies

Alex Geringer-Sameth, Savvas M. Koushiappas, Matthew G. Walker +3

We present methods to assess whether gamma-ray excesses towards Milky Way dwarf galaxies can be attributed to astrophysical sources rather than to dark matter annihilation. As a ca…

Precision measurement of the (e + e) flux in primary cosmic rays from 0.5 GeV to 1 TeV with the Alpha Magnetic Spectrometer on the International Space Station

Manuela Vecchi

We present a precise measurement of the combined electron plus positron flux from 0.5 GeV to 1 TeV, based on the analysis of the data collected by the Alpha Magnetic Spectrometer d…

Precision Measurement of the Proton Flux in Primary Cosmic Rays from 1 GV to 1.8 TV with the Alpha Magnetic Spectrometer on the International Space Station

Cristina Consolandi

A precision measurement of the proton flux in primary cosmic rays with rigidity from 1 GV to 1.8 TV is presented based on 300 million events. The results show that the proton flux…

Magellan/M2FS Spectroscopy of Tucana 2 and Grus 1

Matthew G. Walker, Mario Mateo, Edward W. Olszewski +8

We present results from spectroscopic observations with the Michigan/Magellan Fiber System (M2FS) of stellar targets along the line of sight to the newly-discovered `ultrafai…

Contamination of stellar-kinematic samples and uncertainty about dark matter annihilation profiles in ultrafaint dwarf galaxies: the example of Segue I

V. Bonnivard, D. Maurin, M. G. Walker

The expected gamma-ray flux coming from dark matter annihilation in dwarf spheroidal (dSph) galaxies depends on the so-called `J-factor', the integral of the squared dark matter de…

CLUMPY: Jeans analysis, -ray and neutrino fluxes from dark matter (sub-)structures

Vincent Bonnivard, Moritz Hütten, Emmanuel Nezri +3

We present an update of the CLUMPY code for the calculation of the astrophysical J-factors (from dark matter annihilation/decay) for any Galactic or extragalactic dark matter halo…

Dark matter annihilation and decay profiles for the Reticulum II dwarf spheroidal galaxy

V. Bonnivard, C. Combet, D. Maurin +6

The dwarf spheroidal galaxies (dSph) of the Milky Way are among the most attractive targets for indirect searches of dark matter. In this work, we reconstruct the dark matter annih…

Spherical Jeans analysis for dark matter indirect detection in dwarf spheroidal galaxies - Impact of physical parameters and triaxiality

V. Bonnivard, C. Combet, D. Maurin +1

Dwarf spheroidal (dSph) galaxies are among the most promising targets for the indirect detection of dark matter (DM) from annihilation and/or decay products. Empirical estimates of…
