Shape dynamics: a relational view of the Universe

Shape Dynamics is a new theory of gravity which removes the notion of local relativistic time from the guiding principles of gravity in the universe. It is a very promising approach which has been shown to be equivalent to Einstein's Theory of General Relativity, without being embedded in time. It is inspired by adherence to Mach's Principle, which is violated by Einstein's theory.

Shape Dynamics provides new tools in the quest for a theory that describes quantum gravity. 

Completing the Census of Exoplanetary Systems with Microlensing

Measurements of the demographics of exoplanets over a range of planet and

host star properties provide fundamental empirical constraints on theories of planet formation and evolution.  Because of its unique sensitivity to low-mass, long-period, and free-floating planets, microlensing is an essential complement to our arsenal of planet detection methods. 

The NASA K2 Mission: Extending Kepler's Legacy

The NASA K2 mission makes use of the Kepler spacecraft to expand upon Kepler's groundbreaking discoveries in the fields of exoplanets and astrophysics through new and exciting observations. K2 uses an innovative way of operating the spacecraft by carefully balancing the pressure of photons coming from the Sun. The K2 mission offers long-term, simultaneous optical observation of thousands of objects at high precision.

Gamma Ray Bursts and Recent Results from the Fermi Mission

Dr. Michelson is the Principal Investigator of the Large Area Telescope on the Fermi Observatory.

The Large Area Telescope (LAT) on the Fermi Observatory scans the entire sky once every three hours.  It has revealed many types of high-energy sources including gamma-ray bursts, many types of pulsars, active galaxies, and binary systems.

In this talk Dr. Michelson will give an overview of Fermi’s discoveries and offer speculation of what might be found next, including possible sources of gravitational radiation.

Pluto, the Kuiper belt and the early history of the solar system

Our understanding of the formation of the solar system has undergone a revolution in recent years, owing to new theoretical insights into the origin of Pluto and the discovery of the Kuiper belt and its complex dynamical structure.  The emerging picture is one of dramatic orbital migration of the planets in the early history of the solar system, driven by interaction with the primordial Kuiper belt, which produced the final solar system architecture that we live in today.  The evidence is all over the solar system, as close as the Moon and as far away as Pluto and the remnant Kuiper belt. 

Viewing Solar System Orbital Architecture through an Extrasolar Lens

The statistics of extrasolar planetary systems indicate that the default mode of planetary formation generates planets with orbital periods shorter than 100 days, and masses substantially exceeding that of the Earth. When viewed in this context, the Solar System, which contains no planets interior to Mercury’s 88-day orbit, is unusual. Extra-solar planetary detection surveys also suggest that planets with masses and periods broadly similar to Jupiter’s are somewhat uncommon, with occurrence fraction of less than ~ 10%.
