Beyond the Gaussian: A Higher-Order Correlation Statistic for the Interstellar Medium
Zoom
Douglas Finkbeiner, Harvard University
January 20, 2021
11:00 am - 12:00 pm
Our project to map Milky Way dust has produced 3-D maps of dust density and precise cloud distances, leading to the discovery of the structure known as the Radcliffe Wave. However, these advances have not yet allowed us to do something the CMB community takes…

Exoplanets and The Search for Extraterrestrial Life
Zoom
Ignas Snellen, University of Leiden
November 04, 2020
2:00 pm - 3:00 pm
Placing the solar system in the context of other planetary systems is one of the central objectives driving the study of extrasolar planets. One of the most fascinating questions in modern science is whether other life-bearing planets exist. In this talk I will review the…
Hα Imaging Spectroscopy of Galaxy Clusters Using SITELLE
Zoom
Howard Yee, University of Toronto
October 28, 2020
2:00 pm - 3:00 pm
SITELLE is an 11’x11′ field-of-view imaging Fourier Transform Spectrograph (iFTS) on CFHT. I will briefly describe the history of iFTS and the capability of this new, unique, IFU-like instrument. We are carrying out a program to use SITELLE to study Hα emission in star-forming galaxies…
Galactic Archeology, Near and (Sort of) Far
Zoom
Gail Zasowski, University of Utah
October 07, 2020
2:00 pm - 3:00 pm
Understanding galaxies and their evolution over time is critical for interpreting the stellar history and chemical enrichment of the Universe. Galaxies that lie at different distances help us fill in different pieces of the puzzle — from large statistical samples of coarsely-resolved systems to our…
Comets, unseen planets, and interstellar visitors
Zoom
Scott Tremaine, University of Toronto
September 23, 2020
2:00 pm - 3:00 pm
Comets have inspired awe since prehistoric times, but even today there are only a few thousand comets with well-determined orbits. Nevertheless, the analysis of this limited sample yields a compelling model for the formation, evolution and present distribution of comets. This model implies that the…
“Measuring the Largest Structures in the Universe with the Smallest Telescopes in Space”
Zoom
Michael Zemcov, Rochester Institute of Technology
September 16, 2020
2:00 pm - 3:00 pm
Observational astrophysics has frequently been driven by the desire for ever increasing angular resolution, which has resulted in larger and more expensive telescopes with time. However, telescopes with very small apertures can sometimes perform cosmological measurements as important as their larger siblings. In this talk,…
