This course provides an overview of multi-messenger astronomy, focussing on three main aspects: multi-wavelength electromagnetic (EM) astronomy, particle/cosmic ray astronomy, and gravitational wave (GW) astronomy. The telescope technologies, data analysis, and the primary science questions relevant to each of these will be studied. For radiation, the telescope technologies at each wavelength will be discussed individually, as each region of the electromagnetic spectrum (radio, microwave, infrared, optical, ultraviolet, X-ray, and gamma-ray) requires different detection technologies and analysis techniques. Objects in space that produce radiation, gravitational waves and particles spanning many orders of magnitude in frequency/energy are studied. Different particle detectors (muon and neutrino/detectors, Imaging atmospheric Cherenkov telescopes) and GW detectors (e.g. LIGO, LISA) are reviewed. Each frequency range and domain tells us about different aspects of astronomical sources and the Universe as a whole. We will be studying the universe as it is seen at all wavelengths of light, and the methods we use to image and analyze this light. As well as electromagnetic radiation, we will also cover cosmic rays and the recently discovered gravitational waves, and consider predictions for future discoveries. The structure of the course is largely organized by wavelength and domain, and includes a significant lab / data reduction and analysis component. As a case study we will analyse observations of the first GW event with an EM counterpart, GW170817. A final research project will be carried out using data from state of the art telescopes. Imaging, spectroscopy, polarimetry and time variability are also introduced, for the 3 domains when appropriate. Telescope networks and global collaborations will be discussed, such as those set up for the electromagnetic follow-up of gravitational wave, particle, or high energy transient phenomena.

This is a graduate-level course in elementary particle physics. The course will survey the current understanding of particle properties and interactions, that is the Standard Model.

This course will present an overview of planetary formation and evolution, with particular focus on extrasolar systems. We will begin with a review of the solar system and the basic properties of extrasolar planetary systems. We will then study the formation and evolution of the host star in the context of the early stages of planet formation. We will focus on the evolution of the protoplanetary disk and its influence on planet growth and stability. Next we will explore planet formation and evolution of both gas-giant planets and terrestrial planets, including gravitational interactions and structural evolution. Finally, we will explore planetary atmospheres, focusing primarily on characterized extrasolar atmospheres. We will understand the underlying dynamics, radiative transfer, and observational constraints. Students will gain knowledge of several numerical techniques throughout the course by both developing a few numerical models of their own and also utilizing available numerical packages. The goal of the course is for students to become familiar with the current state of the art in the theory of planet formation and evolution. They should be able to understand content and context of current articles in the field and be prepared for introductory research in the field.

Nearly all physical systems incorporate a large number of particles. However, it is not feasible to simultaneously solve the equations of motion of all components. Therefore, understanding their behavior requires treating their constituent particles as a fluid. This course will teach the concepts and techniques needed to describe and solve for the evolution of the bulk properties of a fluid for a wide range of realistic systems, broadly applicable to main areas of current research.

Students immerse into two seven‐week research experiences during their first full semester on the NYU Abu Dhabi campus.
