A New Boundary Condition on Reionization
Sarah Libanore, Ely D. Kovetz, Julian B. Munoz +2
The epoch of reionization (EoR) marks the last phase transition of hydrogen in our Universe, as it evolves from cold and neutral to hot and ionized in the intergalactic medium (IGM…

Reionization Bubbles from Real-Space Cross Correlations of Line Intensity Maps
Emilie Thélie, Sarah Libanore, Yonatan Sklansky +2
We propose a new way to reconstruct the ionized-bubble size distribution during the Epoch of Reionization (EoR) through the real-space cross-correlation of 21-cm and star-forming l…

The "Dark-Matter Dominated" Galaxy Segue 1 Modeled with a Black Hole and no Dark Halo
Nathaniel Lujan, Karl Gebhardt, Richard Anantua +11
The dwarf spheroidal galaxy, Segue 1, is thought to have one of the largest ratios of dark matter to stellar mass. Using orbit-based dynamical models, we model Segue 1, including a…
