Download Optimized Dark Matter Searches in Deep Observations of Segue by Jelena Aleksić PDF
By Jelena Aleksić
This thesis offers the result of oblique darkish subject searches within the gamma-ray sky of the close to Universe, as noticeable by way of the MAGIC Telescopes. the writer has proposed and led the one hundred sixty hours lengthy observations of the dwarf spheroidal galaxy Segue 1, that is the private survey of one of these item by way of any Cherenkov telescope to this point. in addition, she built and entirely characterised a brand new procedure, dubbed “Full Likelihood”, that optimizes the sensitivity of Cherenkov tools for detection of gamma-ray signs of darkish subject beginning. in comparison to the traditional research options, this novel process introduces a sensitivity development of an element of 2 (i.e. it calls for four instances much less commentary time to accomplish an identical result). moreover, it permits an easy merger of effects from assorted goals and/or detectors.
By opting for the optimum observational aim and mixing its very deep publicity with the complete probability research of the obtained info, the writer has greater the present MAGIC bounds to the darkish subject houses by means of a couple of order of importance. in addition, for debris extra significant than a number of hundred GeV, these are the most powerful constraints from dwarf galaxies completed by way of any gamma-ray tool, either ground-based or space-borne alike.

A General Theory of Magic (Routledge Classics)
First written via Marcel Mauss and Henri Humbert in 1902, A basic idea of Magic received a large new readership while republished through Mauss in 1950. As a learn of magic in 'primitive' societies and its survival this day in our recommendations and social activities, it represents what Claude Lévi-Strauss known as, in an creation to that version, the awesome modernity of the brain of 1 of the century's maximum thinkers.

The dominant final states are composed by heavy particles, like τ + τ − , bb¯ and t t¯ (for sufficiently high masses). • Photons: direct annihilation into photons can occur at one loop level, as χ χ → γ X , where X = γ , Z or h. Such process is strongly suppressed, but not impossible; photons produced this way would be detected as sharp lines at energies E γ ≈ m χ (1 − m 2X /4m 2χ ) (Sect. 3), representing an undoubtable evidence of dark matter detection. Photons can also be produced in the so-called internal bremsstrahlung [53]: if neutralinos annihilate into leptons, the annihilation exchange particle is a charged sparticle that can emit a photon.
