The HUNTER Experiment: A precision massive-neutrino search based on a laser-cooled atomic source
The HUNTER (Heavy Unseen Neutrinos from Total Energy-momentum Reconstruction) experiment bridges Atomic, Molecular, and Optical (AMO) physics with nuclear physics to search for a long-theorized particle. This elusive particle could provide key insights into the universe's mysteries, including dark …

Heavy neutrino matter at finite temperature
We study, for a system of massive fermions which interact only gravitationally, the phase transition that is associated with gravitational collapse. It is shown that by cooling a non-degenerate gas of massive neutrinos below some critical temperature, a condensed phase emerges, consisting of …

THE ASTROPHYSICAL GRAVITATIONAL WAVE BACKGROUND: IMPACTS OF PRIMARY AND SECONDARY ANISOTROPIES ON THE GW-LSS CROSS-CORRELATION
… the universe measured via the “Dark Energy and Massive Neutrino Universe (DEMNUni)” simulation suite. In particular, we present the cross-correlation of the AGWB with CMB convergence, ISW/Rees-Sciama, cosmic shear and galaxy maps from the DEMNUni simulations. Since the properties of the …

Light, Unstable Sterile Neutrinos: Phenomenology, a Search in the IceCube Experiment, and a Global Picture
Longstanding anomalies in neutrino oscillation experiments point to the existence of a fourth, hypothetical neutrino: the sterile neutrino. Global fits to a sterile neutrino model find a strong preference for such a model over the massive neutrino Standard Model. However, the fit results suffer …

GALAXY-HALO CONNECTION AND CLUSTERING IN THE PRESENCE OF DYNAMICAL DARK ENERGY AND MASSIVE NEUTRINOS
… has been used, the so-called “Dark Energy and Massive Neutrino Universe” (DEMNUni) project, spanning several cosmological models with different neutrino masses and/or different equations of state of dynamical dark energy. The author of this Thesis has applied to these simulations the subhalo …

Pulse-shape studies with coplanar grid CdZnTe detectors and searches for rare nuclear decays with the COBRA experiment
The inference of massive neutrino states through the observation of flavor oscillations boosted the importance of direct and indirect mass searches, including the search for the hypothesized neutrinoless double beta decay (0νββ-decay). Nowadays, the search for this ultra-rare nuclear transition is …
