Book Description
In this dissertation, we will look at neutrino production in astrophysical environments and how we can use these environments to probe neutrino physics. Neutrinos carry information about the particle physics processes occurring inside the source. As these neutrinos have energies much larger than those from terrestrial sources and travel cosmological distances to reach us, they can also be used to look for new physics. We look at neutrino production in gamma-ray bursts and magnetars in a semi-analytical way. In both cases, we explore the source parameters that favor neutrino production and its implications for IceCube and future neutrino detectors. Then, we present the neutrino time delay approach to explore Beyond Standard Model interactions. This technique is suitable in multimessenger astrophysics, where we can measure neutrino delay with respect to a photon signal. We look at the time delay distributions obtained from Monte Carlo simulations, which can then be used for statistical analyses. We show an application of this technique in the context of supernova neutrinos and neutrino-dark matter interactions.

Book Description
Abstract Gamma-ray bursts (GRBs) are the most luminous transient events in the observed Universe. However, there is no direct observational evidence for what exactly drives a GRB. The most widely accepted model for these cosmic events is the fireball model where it is thought that a substantial fraction of the kinetic energy of the source is converted to gamma-radiation by shock accelerated electrons emitting synchrotron and inverse-Compton radiation. The acceleration of protons in the gamma-ray emitting region of the GRB has been hypothesized as well. In this hadronic acceleration model, it is predicted that protons may interact with gamma-ray photons to produce a burst of neutrinos at energy ∼10^14 eV during prompt emission and energy ∼10^18 eV during afterglow emission. Several experimental searches for these high energy neutrinos have been conducted and no GRB neutrinos have yet been found. The analytical prediction for neutrino flux has been replaced with a more thorough numerical prediction for neutrino flux. The neutron model of GRBs, where only neutrons can escape the GRB and reach Earth as cosmic rays, has been ruled out by the experimental work of IceCube and ANTARES. Upgraded versions of current experiments such as IceCube, ANTARES, ANITA and ARA, as well as new experiments such as KM3NeT, are preparing to probe and further constrain the fireball paradigm of GRB neutrino production. This review includes: Introduction Early theoretical predictions for neutrino fluences due to GRBs Overview of high energy neutrino experiments and related physics Experimental searches for high energy neutrinos from GRBs Prospects for detection of high energy neutrinos from GRBs High Energy Neutrinos from Gamma Ray Bursts: Theoretical Predictions, Experimental Searches, and Prospects for Detection was originally written as a review submitted for my Ph.D. candidacy paper on Nov 23, 2015. It has been edited for a "Short Read" on Amazon Kindle Direct Publishing in Oct 2020. It is a public domain work. Special thanks to the Connolly group at Ohio State University (OSU) and the physics and astronomy departments at OSU. Moreover, I am grateful for the contribution of each and every scientist and author listed in the "References" section of this review. This review would not be possible without their published science and hard work. Please let me know if you find any mistakes or problems, I will fix it. My email is [email protected]. I am happy for this to be a living document. I am anxious to improve it but feel that it needs to be out at this point before that can happen.

Book Description
This book provides a pedagogical introduction to the likely sources of these neutrinos, their propagation and detection mechanisms. Detection of high energy neutrinos of extragalactic origin has led to an interdisciplinary field of research, involving astronomy, astrophysics and particle physics. An extensive review of various detectors and the observations is provided that consolidates the latest findings. Above a few tens of TeVs, neutrinos are conceived as more reliable messengers for astronomy than photons as these photons get absorbed in the background photon field. Determining the neutrino spectrum not only helps in exploring astrophysical objects like AGN, GRB, etc. but also allows us to study particle physics at unprecedented energies. This introductory book is intended to help advanced undergraduate and graduate students to get into the subject with ease, and it simultaneously caters to practicing theoretical or experimental physicists as a reference book.

Book Description
The proceedings of this workshop consideres the prospects for opening up a new window on the universe with the generation of High Energy Neutrino telescopes now under construction or being planned. Potential sources of high energy neutrinos such as binary pulsars, supernovae, and active galactic nuclei are discussed. In particular, the recent model of Stecker and collaborators, in which neutrinos with energies as high as 1000 TeV are produced in measurable quantities in the cores of quasars and other active galaxies is critically reviewed.

Book Description
This book summarizes the science to be carried out by the upcoming Cherenkov Telescope Array, a major ground-based gamma-ray observatory that will be constructed over the next six to eight years. The major scientific themes, as well as core program of key science projects, have been developed by the CTA Consortium, a collaboration of scientists from many institutions worldwide.CTA will be the major facility in high-energy and very high-energy photon astronomy over the next decade and beyond. CTA will have capabilities well beyond past and present observatories. Thus, CTA's science program is expected to be rich and broad and will complement other major multiwavelength and multimessenger facilities. This book is intended to be the primary resource for the science case for CTA and it thus will be of great interest to the broader physics and astronomy communities. The electronic version (e-book) is available in open access.
