Interpreting the ALMA continuum images of protoplanetary disks

Zoom

Kees Dullemond, University of Heidelberg

February 17, 2021
2:00 pm - 3:00 pm

In recent years a large number of high-resolution ALMA images of protoplanetary disks were published. It is striking how cleanly structured these disks appear to be: they feature nearly perfect rings of dust, with every now and then an elliptic blob, and sometimes m=2 “grand…

Colloquia with Lamiya Mowla and Keir Rogers

Zoom

Local Postdoctoral Fellows, University of Toronto

February 10, 2021
2:00 pm - 3:00 pm

Making it Big: The Effect of Dust on Galaxy Morphology – by Lamiya Mowla Galaxy morphology is one of the fundamental and oldest observational tools used to study the formation and evolution of galaxies. Decades of observations from the ground and thousands of orbits of…

Exoplanet Host Star Age Inferences and Their Impacts on Models of Planet Formation and Evolution

Zoom

Kevin Schlaufman, Johns Hopkins

February 03, 2021
2:00 pm - 3:00 pm

Precise ages for exoplanet host stars have among their many uses the potential to reveal the origin and fate of short-period planets, the effect of host star mass on giant planet formation, the structure and role of atmospheric escape in the evolution of low-mass planets,…

Pinpointing fast radio bursts in space and time

Zoom

Jason Hessels, University of Amsterdam

January 27, 2021
2:00 pm - 3:00 pm

In the past decade we have started to explore extragalactic and intergalactic space using millisecond-duration radio flashes called `fast radio bursts’ (FRBs). These cosmological signals are surprisingly abundant: there is likely an FRB occurring somewhere on the sky at least once every minute. But what…

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…
