1174. Dark Matter searches with Fermi LAT in direction of dwarf spheroidals

Oral contribution

The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-dominated objects known. Due to their proximity, high dark matter content, and lack of astrophysical backgrounds, dwarf spheroidal galaxies are widely considered to be among the most promising targets for the indirect detection of dark matter via gamma rays. Here we report on gamma-ray observations of...

66. Constraining the Dark Matter lifetime with very deep observations of the Perseus cluster with MAGIC

DM-EX

Oral contribution

We present the results on Dark Matter searches from the Perseus galaxy cluster observations with the MAGIC Telescopes. MAGIC is a system of two Imaging Atmospheric Cherenkov Telescopes located in the Canary island of la Palma, Spain. Galaxy clusters are the largest known gravitationally bound structures in the Universe, with masses of ~10^15 Solar Masses. There is strong evidence that galaxy...

279. Dark matter search in the inner Galactic halo with H.E.S.S. II

Oral contribution

The presence of dark matter in the Universe is nowadays widely supported by a large body of astronomical and cosmological observations. One of the best target to look for dark matter self-annihilation into very high energy gamma-rays is the Galactic center region. A search for such emission is performed with the ground-based H.E.S.S. array of Cherenkov telescopes toward the central 150 parsecs...

757. Status of cosmic ray antideuteron searches

Prof. Philip Von Doetinchem (University of Hawaii at Manoa)

DM-EX

Oral contribution

The precise measurement of cosmic ray antiparticles serves as important means for identifying the nature of dark matter. Recent years showed that identifying the nature of dark matter with cosmic ray positrons and higher energy antiprotons is difficult, and has lead to a significantly increased interest in cosmic ray antideuteron searches. Antideuterons may also be generated in dark matter...

46. Prospects for Indirect Dark Matter Searches with the Cherenkov Telescope Array (CTA)

John Carr (CPPM/IN2P3/CNRS)

DM-EX

Oral contribution

The existence of dark matter (DM) as the dominant contribution to the gravitational mass of the Universe is by now well established but the corpuscular nature of DM is at present unknown. Multiple hypotheses endure as to the character of DM and for the most popular DM models the CTA has a unique chance of discovery. The principal target for DM searches with CTA is the Galactic Centre (GC)...

402. First Limits on the Dark Matter Cross-Section with the HAWC Observatory

Brenda Dingus (Los Alamos National Lab)

DM-EX

Oral contribution

The High Altitude Water Cherenkov (HAWC) gamma-ray observatory is a wide field-of-view observatory sensitive to 100 GeV – 100 TeV gamma-rays and cosmic-rays. The HAWC observatory is also sensitive to diverse indirect searches for dark matter annihilation, including annihilation from extended dark matter sources, the diffuse gamma-ray emission from dark matter annihilation, and gamma-ray...
