Abstract

Astrophysical neutrinos are excellent probes of astroparticle physics and high-energy physics. With energies far beyond solar, supernovae, atmospheric, and accelerator neutrinos, high-energy and ultra-high-energy neutrinos probe fundamental physics from the TeV scale to the EeV scale and beyond. They are sensitive to physics both within and beyond the Standard Model through their production mechanisms and in their propagation over cosmological distances. They carry unique information about their extreme non-thermal sources by giving insight into regions that are opaque to electromagnetic radiation. This white paper describes the opportunities astrophysical neutrino observations offer for astrophysics and high-energy physics, today and in coming years.

Abstract

High-energy cosmic neutrinos carry unique information about the most energetic non-thermal sources in the Universe. This white paper describes the outstanding astrophysics questions that neutrino astronomy can address in the coming decade. A companion white paper discusses how the observation of cosmic neutrinos can address open questions in fundamental physics. Detailed measurements of the diffuse neutrino flux, measurements of neutrinos from point sources, and multi-messenger observations with neutrinos will enable the discovery and characterization of the most energetic sources in the Universe., Comment: White paper for the Astro2020 US decadal survey.

Abstract

In the last decade, new classes of sources (fast radio burst, binary neutron star mergers, ...) have been discovered thanks to progress in photon astronomy at all wavelengths. With the advent of multimessenger astronomy, we were able to scrutinize them with cosmic rays, neutrinos, photons and gravitational waves. The first part of this thesis is dedicated to the study of the high-energy and ultra-high energy neutrinos. Since the discovery in 2013 by IceCube of a diffuse neutrino flux, two major questions have been raised: what are the sources of this diffuse flux, and can we detect neutrinos at higher energies (> PeV). To help answering these questions, we first present a model of high-energy neutrino emissions from neutron star mergers. We then examine the radio detection of extensive air showers induced by ultra-high-energy neutrinos, with a study of a detector optimisation, and a detailed analysis of the signal characteristics and develops a reconstruction procedure. The second part of this thesis is dedicated to the study of the fast radio bursts. These brief, coherent and numerous radio pulses, have not been identified yet and many experimental unknowns remain. We first propose a source model focusing on the question of the pulses rates. Finally, we present an observational program conducted with the NenuFAR instrument, located in the Nançay Radio Astronomy Station, dedicated to the detection and the characterisation of FRBs at low frequency (PeV). Afin d’aider à répondre à ces questions, nous présentons en premier un modèle d’émission de neutrinos de hautes énergies résultant de la fusion d’étoiles à neutron. Nous examinons ensuite la possibilité de radio détecter les gerbes atmosphériques induites par les neutrinos d’ultra hautes énergies, à travers une étude sur l’optimisation d’un tel détecteur, et une analyse détaillée des caractéristiques du signal et de sa reconstruction. La deuxième partie de cette thèse est dédiée à l’étude des sursauts radio rapides (FRB). Ces pulses radio, brefs, cohérents et nombreux, n’ont pas été identifiés encore et de nombreuses inconnues expérimentales persistent. En premier, nous proposons un modèle de source expliquant les taux de sursauts observés. Enfin, nous présentons un programme observationnel, conduit par l’instrument NenuFAR, situé à la Station de Radio Astronomy de Nançay, dédié à l’observation des FRB aux basses fréquences (100MHz).
