Link to Video:Statistics Meets Astronomy: Challenges in Time and Space
Date: July 8 2020

Astronomy, like so many other disciplines, has entered an era of big data — large telescopes and all-sky surveys are bringing in petabytes amount of data on a daily basis. The hope is that these large data sets will help us not only untangle mysteries of the universe but also help us discover new phenomena. At the same time, these data sets often come with challenges that require sophisticated statistical analysis. In this talk, I will summarize some of the exciting science being done by my Astrostatistics Research Team at the University of Toronto, from studies of individual stars, to open star clusters and the entire Milky Way Galaxy.

Date: August 12 2020

The cosmic microwave background (CMB) is the glow of the
universe from soon after the Big Bang. Today, we can observe this nearly 14 billion-year-old light with microwave telescopes and use it to determine some of the most fundamental properties of the cosmos, such as its age, what it is made out of, and how fast it is expanding. We can also learn how the universe behaved in its very first instants. I will introduce this exciting science and describe how we observe the CMB, focusing in particular on the Atacama Cosmology Telescope and the Simons Observatory—the first currently observing and the second under development—located in the north of Chile.

Link to Video: Hands-On Astronomy: Building Instruments to Measure Our Cosmos
Date: September 30 2020
Blog Link: Here

You may be familiar with some of the fantastic technology and instruments to do astronomy and the pictures we get with them of our cosmos, but how do these telescopes and cameras actually get built? What do experimental astrophysics do all day? I will discuss astronomical instrumentation and what technology we use to measure the sky across the electromagnetic spectrum from UV telescopes to superconducting transition edge sensors. I will describe how these instruments are created and what the careers of astronomy “builders” are like. I will also show some images of the sky taken with different instruments and describe the discoveries they have allowed astronomers to make.
