## 16:750:543 GALAXIES AND THE MILKY WAY (3)

- Course Description:
Properties of galaxies; photometry, kinematics, and masses. Disk galaxies, spiral patterns, bars and warps, gas content, star formation rates, chemical evolution. Elliptical galaxies: shapes. Structure of the Milky Way. The nature of dark matter.

Galaxies are an important nexus in the cosmic hierarchy: they serve as lighthouses marking out the vast cosmic structures that can span many millions of parsecs, but are fascinating in themselves as laboratories for the "small scale" processes of stellar birth and evolution. We now have images of billions of galaxies, and can observe them from a time less than a billion years after the Big Bang until the present day. We can study not only the appearance or "morphology" of galaxies, but also in some cases measure properties of their stellar populations, their quota of heavy elements, their gas content, and the internal motions (or kinematics) of their stars and gas. Although galaxies exhibit amazing diversity, they also conform to certain surprisingly tight correlations. From kinematic measurements, we can infer that galaxies contain a major unseen component that influences the motions of their stars and gas: the mysterious "dark matter". Moreover, the stars and gas that we can measure within galaxies falls far short of what we would expect for the cosmic "baryon budget". The study of modern galaxy formation focuses on trying to understand the observed demographics and correlations of galaxy properties and how these evolve over cosmic time, in the context of the "hierarchical structure formation" picture provided by the Cold Dark Matter theory.

In this course, we will warm up with a brief review of stars and radiative processes and basic cosmology. We will start our study of galaxies with our home Galaxy, the Milky Way, our sister galaxy M31 (Andromeda), and our smaller companions the Local Group dwarfs. Even this relatively small population of galaxies in our own "backyard" poses a number of unsolved puzzles. We will then cover the properties of spiral, lenticular, and elliptical galaxies in the 'nearby' Universe, and discuss the larger structures that form galaxy habitats: groups and clusters. One fascinating open question is whether galaxy properties are mainly shaped by "internal" processes or by their environment. We will discuss the evidence that many or even most galaxies harbor supermassive black holes in their nuclei. We will wind up the course with a discussion of how we can find and observe extremely distant (high redshift) galaxies, and of how galaxies were different in the past.

## 16:750:612 HIGH-ENERGY ASTROPHYSICS (3)

- Course Description:
Prerequisite: 750:341-342 or equivalent. The origin and detection of high energy photons and particles in the universe. Radiation processes in low density media. Sites of high energy phenomena in astrophysics, such as supernovae, pulsars, active galactic nuclei and quasars and processes such as accretion and shocks.

The Universe is filled with diverse objects and phenomena ranging from those with very low characteristic temperatures, such as the 2.7 K Cosmic Microwave Background Radiation, to the ultrahigh energy cosmic rays in which a single particle can carry 10 J or more of energy. Accordingly in order to attempt a complete understanding of cosmic objects and events, astrophysicists have been driven to conduct studies over the entire electromagnetic spectrum. In this course, the focus will be on the study of high energy astrophysics, that is to say, the field of astronomy that concerns itself with objects and phenomena having a characteristic temperature greater than about 10^6 K or equivalently 0.1 keV. This includes the X-ray and gamma-ray bands of the electromagnetic spectrum, cosmic rays, and neutrinos from the Sun and supernovae. The field is relatively new: cosmic rays were discovered in 1912 (although not explained as high energy particles until 1929) and, although, X-rays were discovered by Rongten in 1895, X-ray astronomy wasn't born until 1949 when the Sun was discovered as the first extraterrestrial X-ray source. In general the history of X-ray and gamma-ray astronomy has paralleled the history of space exploration. Neutrino astronomy is even younger, commencing with the Homestake gold mine experiment in the 1970's which gave rise to the famous "solar neutrino" problem.

This course is intended to provide the student with sufficient background material and knowledge in order to appreciate current research literature in high energy astrophysics. It will draw on graduate level physics and astronomy as prerequisites. Although the text listed above is required, some course material will be taken from other sources, such as "Radiative Precesses in Astrophysics" by Rybicki and Lightman (Wiley), particularly for lectures on radiative processes. Students might consider looking at the readable book on X-ray astronomy "Exploring the X-ray Universe" by Charles and Seward (Cambridge).

Gravitational lensing has matured into a thriving area of astrophysics, with applications across a wide range of scales and redshifts. The goals for this course are as follows:

- Understand the theory and phenomenology of gravitational lensing.
- Gain experience with quantitative aspects of lensing.
- Examine a variety of astrophysical applications of lensing.

We will develop the analytic theory as much as possible and consider computational approaches as appropriate. Some of the applications we will discuss include: properties of stars, planets, and stellar remnants; physical properties of galaxies; dark matter in galaxies and clusters of galaxies; structure of high-redshift galaxies and quasars; cosmological parameters.

This is an advanced graduate course designed for students pursuing research in physics and astronomy. Undergraduate physics and mathematics should provide adequate preparation. Familiarity with intermediate classical mechanics, electrodynamics, and quantum mechanics are helpful, as much of the mathematics encountered in those subjects applies to lensing.

## 16:750:690 ADVANCED TOPICS IN ASTROPHYSICS (3)

- Course Description:
The last decade has witnessed a revolution in our cosmological understanding: multiple lines of evidence show that we live in a Universe dominated by the effects of dark energy and dark matter. Characterizing the properties of these components is the frontier of current research. In this seminar, we will trace the development of these dark components in the standard cosmological model. We will also discuss current and proposed experiments to constrain the nature of dark matter and dark energy, and explore potential alternatives to the standard paradigm.

With quantum fluctuations in the early universe seeding superclusters and voids today, particle dark matter halos shaping and supporting galaxies, and vacuum energy driving the accelerating expansion, modern cosmology directly connects physics at the largest and smallest scales. As such, this course is broadly aimed to engage graduate students across physics, enabling a synthesis of observational, experimental, and theoretical results.

The course will have a reading/seminar format. We will meet weekly to discuss a few (~4) important papers on a specific topic, and two students will be assigned to lead the presentation for that week.

## 16:750:694 ADVANCED TOPICS IN HIGH ENERGY PHYSICS (3)

- Course Description:
This is a special topics seminar aimed at 1st and 2nd year graduate students who intend to pursue a Ph.D. in experimental particle physics. The course is intended to bridge the gap in knowledge between formal theoretical physics (i.e. QFT) and experimental practice. Particle interactions in matter and detector techniques will be emphasized in relation to the historic development of our understanding of fundamental physics. Students will be expected to do the reading and associated problems prior to class, where the readings will be discussed in a seminar-style format.

## 16:750:695 ADVANCED TOPICS IN MATH PHYSICS (3)

- Course Description:
The past 20 years have been an exciting time for the interaction of mathematics and physics. Remarkable new mathematical discoveries have been made using the methods of quantum field theory. Conversely, powerful new mathematical techniques have been successfully applied to gain nontrivial insights in sophisticated theories like supersymmetric gauge theories and string theory.

The purpose of this course is to provide some of the mathematical background which one needs in order to learn about these modern developments. The course surveys some aspects of topology and differential geometry of manifolds, with an emphasis on relations to modern mathematical physics. The course will also cover some aspects of supersymmetry.

This course is primarily intended for physics graduate students specializing in theoretical physics.

Some knowledge of manifolds, differential forms, and cohomology will be assumed, but we will try to keep the course material self-contained.
