Formation and Evolution of the Cosmic Microwave Background: Recombination

When the Universe was about 370.000 years old electrons were rapidly captured by protons in the Universe. This process is known as recombination and led to the formation of a flash of light known as the Cosmic Microwave Background (CMB). The CMB is the most powerful cosmological data set to date and its pattern is strongly dependent upon the physics of the process of recombination. The idea of the project will be to revisit the physics of recombination. In particular, studying the ionization processes and cosmological expansion history within the standard cosmological model. In addition, if time allows,  the process of recombination when dark matter particles annihilate could be studied, and perhaps the subsequent evolution of the Universe until the first stars begin to form, known as reionization.

The Migdal effect and applications to dark matter searches

Atoms can be ionized by the interaction of a photon with one of the electrons in the atomic orbitals. As pointed out by Migdal in 1939, atoms could also be ionized by the interaction of a neutron with the atomic nucleus.  This process has been revisited recently in the context of dark matter detection. The most common strategy for dark matter detection is the search for nuclear recoils induced by dark matter interactions with the nucleus. However, the Migdal effect could also induce the ionization of the atom, leading to additional (sometimes unique) dark matter signals. In this bachelor thesis the student will calculate the probability of ionization of an atom due to the Migdal effect, and will analyze the implications for dark matter searches.
