Description

This lecture covers the operation of neutrino and gravitational wave telescopes, such as Super-Kamiokande, IceCube, and LIGO. It explains how gravitational wave telescopes work using laser light, mirrors, beam splitters, and detectors. It also discusses global astronomy events like GW170817 and the solar neutrino problem, including neutrino oscillations and interactions in nuclear reactors.

The Radio Sky II: Observational Radio Astronomy

The first part of the course introduces the different types of telescope technologies available to astronomers, with a particular focus on single-dish radio telescopes and radio interferometers. Optical, UV, X-ray, Gamma, neutrino, and gravitational wave telescopes will also be briefly covered, as well as a foray into Search for Extraterrestrial Intelligence. We, then, dive deep into the principles of observational radio astronomy, covering the observables (flux, luminosity, brightness temperature), and th

Neutrino oscillation

Neutrino oscillation is a quantum mechanical phenomenon in which a neutrino created with a specific lepton family number ("lepton flavor": electron, muon, or tau) can later be measured to have a different lepton family number. The probability of measuring a particular flavor for a neutrino varies between three known states, as it propagates through space. First predicted by Bruno Pontecorvo in 1957, neutrino oscillation has since been observed by a multitude of experiments in several different contexts.

Shape of the universe

The shape of the universe, in physical cosmology, is the local and global geometry of the universe. The local features of the geometry of the universe are primarily described by its curvature, whereas the topology of the universe describes general global properties of its shape as a continuous object. The spatial curvature is described by general relativity, which describes how spacetime is curved due to the effect of gravity.

Solar neutrino problem

The solar neutrino problem concerned a large discrepancy between the flux of solar neutrinos as predicted from the Sun's luminosity and as measured directly. The discrepancy was first observed in the mid-1960s and was resolved around 2002. The flux of neutrinos at Earth is several tens of billions per square centimetre per second, mostly from the Sun's core. They are nevertheless hard to detect, because they interact very weakly with matter, traversing the whole Earth.

Ultimate fate of the universe

The ultimate fate of the universe is a topic in physical cosmology, whose theoretical restrictions allow possible scenarios for the evolution and ultimate fate of the universe to be described and evaluated. Based on available observational evidence, deciding the fate and evolution of the universe has become a valid cosmological question, being beyond the mostly untestable constraints of mythological or theological beliefs.

Static universe

In cosmology, a static universe (also referred to as stationary, infinite, static infinite or static eternal) is a cosmological model in which the universe is both spatially and temporally infinite, and space is neither expanding nor contracting. Such a universe does not have so-called spatial curvature; that is to say that it is 'flat' or Euclidean. A static infinite universe was first proposed by English astronomer Thomas Digges (1546–1595).
