Colloquium

This is a talk held during the regular colloquium series (usually Tuesdays at 4pm).

Cosmology, Big and Small: Probing the Multi-scale Nature of Structure Formation with Artificial Universes

Thursday, March 18, 2021 - 11:00am
Dr. Sownak Bose (Harvard University)

In our present paradigm of galaxy formation, the onset of structure is brought about via the gravitational collapse of dark matter, which subsequently acts as the scaffolding for the visible universe.

New Instruments and Observational Techniques for Interpreting the Spectra of Exoplanets

Tuesday, March 16, 2021 - 11:00am
Dr. Emily Martin (UC Santa Cruz)

There are now thousands of known exoplanets in our galaxy and yet characterizing them remains a technical challenge. Solar System planets and brown dwarfs can serve as benchmarks for exoplanet observations and they provide high signal-to-noise data that we cannot yet access for exoplanets.

An ALMA view of galaxies in the Epoch of Reionization

Tuesday, April 20, 2021 - 11:00am
Dr. Renske Smit (Liverpool John Moores University)

In the past decade hundreds of galaxy candidates have been identified in the Epoch of Reionization (EoR), selected from their rest-frame UV light. Only a handful of these sources, however, have spectroscopic redshift determinations and we have limited understanding of their properties.
