Title: Zero-Range Effective Field Theory for Resonant Wino Dark Matter

Abstract:

The most dramatic "Sommerfeld enhancements" of neutral-wino-pair annihilation occur when the wino mass is tuned to near critical values where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold. If the wino mass is larger than the critical value, the resonance is a wino-pair bound state. If the wino mass is near a critical value, low-energy winos can be described by a zero-range effective field theory in which the winos interact nonperturbatively through a contact interaction. The parameters of the zero-range effective field theory can be determined by matching wino scattering amplitudes calculated by solving the Schroedinger equation for a nonrelativistic effective field theory in which the winos interact nonperturbatively through a potential due to the exchange of weak gauge bosons. The power of the zero-range effective field theory is illustrated by calculating the rate for formation of the bound state in the collision of two neutral winos through the emission of two soft photons.

Title: The Solar Modulation of GCR: Possible Effect on the Time Variation in the Solar Gamma-Ray

Abstract:

Fermi-LAT observation revealed that the solar-disk gamma-ray flux is about 7 times higher than predicted during the solar minimum and it has a time dependence associated with the solar activity levels. While it is expected that the time dependence of the solar gamma-ray flux has relation to the time variations in the galactic cosmic-ray (GCR) flux and/or the solar magnetic field, the details are still unknown. It was observed that the latitudinal and radial dependence of the GCR flux changes with a solar activity levels by the heliospheric network of spacecraft, Pioneer 10/11, Voyager 1/2, Ulysses, and IMP-8. Therefore, there is a possibility that the GCR flux near the sun also may have a time variation and it may affect the resultant solar gamma-ray flux. I will present our results of the time variation in the GCR flux in the solar system calculated by using the drift model of the solar modulation, and discuss the possible effect of the solar modulation of GCR on the time variation of the solar gamma-ray.

Title: Neutrino flavour conversions in supernova: recent developments

Abstract:

The study of neutrino flavor evolution in supernovae has recently pointed out that relaxing the symmetries of the standard bulb model, which was commonly adopted until a few years ago for describing neutrino emission and propagation, might introduce instabilities in flavor space, which are exponentially growing in both time and space. In this talk I focus on two kind of instabilities. First I show that space and time inhomogeneities can excite flavor conversions at small spatial scales and can spontaneously generate a pulsating component in the flavor composition. In particular, the pulsation can compensate the suppression of flavor conversions induced by large matter effects. Then, I will discuss the so called “fast flavour conversions”, which develop a few meters from the supernova core, introducing both decoherence and flavour equilibration. If confirmed, both instabilities may have an important role in supernova explosion, such as in the shock reheating and in nucleosynthesis processes.

Title: Hidden Sector Hydrogen as Dark Matter: Predictions for Small-scale Structure

Abstract:

I will discuss the atomic physics and the astrophysical implications of a model in which the dark matter is the analog of hydrogen in a secluded sector. The self interactions between dark matter particles include both elastic scatterings as well as inelastic processes due to a hyperfine transition. The self-interaction cross sections are computed by numerically solving the coupled Schrodinger equations for this system. The velocity-dependence of the self-interaction cross sections produces the low dark matter density cores seen in spiral galaxies while maintaining consistency with constraints from observations of galaxy clusters. Significant cooling losses may occur due to inelastic excitations to the hyperfine state and subsequent decays (up to about 10% of the collisional heating rate) in this region of parameter space, with implications for the evolution of low mass halos and early growth of black holes. Finally, the minimum halo mass is in the range of 10^3 to 10^7 solar masses for viable regions of parameter space, which is significantly larger than the typical predictions for weakly-interacting dark matter models.

Title: New physics in Supernovae

Abstract:

Dark matter (DM) particles can be captured by stars via scattering on ordinary matter. As a benchmark

model for s-wave and p-wave annihilation we consider DM annihilation into dark photons and dark scalars

which further decay into SM particles. We trace DM capture and annihilation rates throughout the life of a

massive star and show that this evolution ends in an observable gamma ray flash. The special feature of

the model is that the photon flux from p-wave annihilation is stronger in comparison to the one from s-wave

process.

Title: Modelling the propagation of ultra-high-energy cosmic rays

Abstract:

The origin and nature of the ultra-high-energy cosmic rays (UHECRs) is one of the main challenges astroparticle physics.

I will discuss the difficulties in modelling the propagation of ultra-high-energy cosmic rays, given our limited knowledge of

the extragalactic background light, photonuclear interactions, and cosmic magnetic fields. Particularly, I will focus on the

influence of magnetic fields on the propagation, and discuss the prospects for UHECR astronomy in light of results of

numerical simulations of cosmic ray propagation in the magnetised cosmic web.

Title: Light from Dark Matter

Abstract:

In this talk I will discuss photon spectra from annihilating Dark Matter. In particular the search for monochromatic lines is of great interest, as from the particle physics perspective it allows to determine the DM mass. And from the astrophysical perspective it is unlikely to be mimicked by a compact source.

I will address the general question, under which circumstances in a given model a line is in principle observable given a finite instrument resolution. Two mechanisms which allow to see such gamma line features will be presented and the corresponding model realisations discussed.

I will discuss how line searches open the window of possibility to scrutinise possible observed continuous gamma ray excesses. As concrete examples the Galactic Center excess and the Reticulum II excess will be considered.

Title: Dark Matter Ignition of Type Ia Supernovae and the R-Process Abundance of Reticulum II

Abstract: Recent studies of low-redshift type Ia supernovae indicate that half explode from sub-Chandrasekhar mass progenitor white dwarfs. This talk explains how asymmetric dark matter would ignite sub-Chandrasekhar white dwarfs, and form star-destroying black holes inside old neutron stars inhabiting regions densely populated with dark matter. The anomalously high r-process abundance of Reticulum II and explanations thereof, including dark-matter-induced neutron star implosions, will also be discussed.

Title:Diffuse gamma-ray emission modeling near the Galactic Center and the 3 GeV excess

Abstract: Several groups have reported excess emission in gamma rays peaking around 3 GeV relative to expectations from conventional models for the interstellar emission in the Galactic Center (GC). We study the uncertainty of the excess emission in Pass 8 Fermi-LAT data due to modeling of the various emission components in that direction. In particular, we quantify the uncertainties on the excess by refitting with several GALPROP models of Galactic diffuse emission, an alternative distribution of gas along the line of sight based on starlight extinction data, a model of the Fermi bubbles at low latitudes, and including templates for additional sources of cosmic-ray electrons near the GC. In all models that we have tested the excess emission remains significant. The origin of the excess is currently uncertain. To test the robustness of a dark-matter interpretation, we perform fits in controls regions along the Galactic Plane. The uncertainties from our fits in control regions have a similar relative size as the excess in the GC. Therefore a non-dark-matter explanation cannot be ruled out and we consequently set limits on the dark matter annihilation cross section.
