"Exoplanet Atmospheric Retrieval in the Era of JWST"

JWST is now delivering ultra-precise spectra of exoplanet atmospheres over a significantly wider wavelength range than afforded by previous observations. This exceptional improvement in data quality will soon address atmospheric science questions that were previously out of reach. Converting an observed spectrum into statistical constraints on atmospheric properties - such as the chemical composition - relies on a Bayesian computational technique known as atmospheric retrieval.

I will summarize our current knowledge of... Read more about ITC Colloquium - Ryan MacDonald (Michigan)

"Full of Hot Air: Wind-Fed GRMHD Simulations of Sagittarius A*"

Sagittarius A* (Sgr A*), the supermassive black hole in the Galactic Center has always been of prime interest to the astrophysical community due to its proximity and relatively high angular resolution in the sky.  This is even more true now that the Event Horizon Telescope has resolved the 230 GHz emission and the GRAVITY interferometer has observed the orbital path of NIR flares at ~ 5 times the Schwarzschild radius of the black hole, giving new and exciting constraints on the accretion flow.  Our...

"Our Lonely Sun: How Multiple Star Systems Form (or don’t)"

Most stars are born with one or more stellar companions. Observational advances over the last decade have enabled high-resolution, interferometric studies of forming multiple systems and statistical surveys of multiplicity in star-forming regions. These have yielded new insights into how such systems form and how multiplicity affects disk evolution and planetary architectures. In this talk, I will review recent observational discoveries of the youngest multiple systems. I will present the results of star cluster...
