"Galaxy Evolution: Gas phases and Feedback" Studying galaxy evolution is a human endeavour. Simulations would ideally include physical models based on relevance, but we are often limited by practical considerations like CPU time and code complexity. I...

Random angular momentum in convection: delayed explosions of red supergiants following “failed” supernovae Red supergiants (RSGs) are the most common stars that will undergo iron core collapse. Successful explosions of RSGs following core collapse lead to...

“Next-Generation Simulations of The Remarkable Deaths of Massive Stars” Multidimensional progenitor models can enable us to capture the chaotic nuclear shell burning occurring deep within the interior of a massive star. I will discuss ongoing efforts to...

"Chaotic Tides and Hot Jupiter Formation" Abstract: Many hot Jupiters (HJs) have been observed to have large obliquities or misalignments between the stellar spin axis and the orbital angular momentum of the planet. This observation hints that at least a...

"LISA's role in multi-band and multi-messenger astronomy for stellar-origin sources" Abstract: The Galactic population of double stellar remnants will be the largest source class, by number, for LISA as well as the largest noise source for the mission at...

"Astrophysics with CMB Surveys" High-resolution ground-based CMB experiments provide new perspectives on many areas of astrophysics. As examples, I will talk about current work using the South Pole Telescope as well as possibilities for future CMB...

In Pratt!! "Worlds and Suns in Context: Environments & Evolutionary Pathways" The growing population of exoplanets and the expanding repertoire of instruments and analysis techniques make it possible to examine moons, planets, and suns within the context...
