Tamara Davis ( University of Queensland )

Chasing Dark Energy

This talk will review the current state of dark energy research and in particular The Australian Dark Energy Survey’s program to measure spectra of tens of thousands of galaxies, thousands of supernovae, and time-lapse spectroscopy of almost 800 AGN. We’ll discuss what we need to do to distinguish between different models of dark energy and prospects of doing that in the next generation of surveys.

Jo Bovy ( University of Toronto )

The Milky Way in the era of large surveys

For over a hundred years, the Milky Way has been the nexus between many fields of astrophysics, linking together investigations into the formation of planetary systems and stars to studies of galactic evolution, cosmology, and astroparticle physics. Obtaining a detailed understanding of our Galaxy’s structure, formation, and evolution is therefore crucial to the advancement of the whole of astrophysical knowledge. Long thought to be a simple spiral galaxy with a simple disk-plus-bulge structure leading a relatively unperturbed life, the advent of large surveys such as SDSS, Gaia, and soon LSST has breathed new life into the field of galactic structure. I will discuss the new view of the Milky Way—complex, dynamic, and very much in the process of evolving—and what it implies about galaxy formation, galaxy evolution, and the nature of dark matter.

Joseph Masiero ( JPL NASA )

NEOWISE tools and techniques

The NEOWISE infrared space telescope has provided an unprecedented set of infrared photometry and astrometry of the entire sky. This includes stars and galaxies, as well as over 150,000 asteroids and comets in our Solar system. I will provide an overview of the data that are publicly available, the tools and techniques that are included to access this data, and some of the results that have been derived from these measurements.
