New boundary condition on reionization

Sarah Libanore, Ely D. Kovetz, Julián B. Muñoz, Yonatan Sklansky et autres

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). While its end point and duration can be estimated from current …

Reionization Bubbles from Real-Space Cross Correlations of Line Intensity Maps

Émilie Thélie, Sarah Libanore, Yonatan Sklansky, Julian B. Muñoz et autres

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 line-intensity maps. Understanding the evolution and timing of the EoR is crucial for both astrophysics and cosmology, …

Modeling the “Dark-matter Dominated” Dwarf Galaxy Segue 1 with a Supermassive Black Hole

Nathaniel Lujan, Karl Gebhardt, Richard Anantua, Owen Chase et autres

Abstract 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 dark halo and a central black hole. The best-fit model …
