Ray-tracing Fast Radio Bursts Through IllustrisTNG: Cosmological Dispersion Measures from Redshift 0 to 5.5

Ralf M. Konietzka, Liam Connor, Vadim A. Semenov +3

The dispersion measures (DMs) of Fast Radio Bursts (FRBs) arise predominantly from free electrons in the large-scale structure of the Universe. The increasing number of FRB observa…

Secular Attrition of Classical Bulges by Stellar Bars

Rachel Lee McClure, Tobias Géron, Elena D'Onghia +5

Classical bulges and stellar bars are common features in disk galaxies and serve as key tracers of galactic evolution. Angular momentum exchange at bar resonances drives secular mo…

Deriving Stellar Properties, Distances, and Reddenings using Photometry and Astrometry with BRUTUS

Joshua S. Speagle, Catherine Zucker, Angus Beane +18

We present brutus, an open source Python package for quickly deriving stellar properties, distances, and reddenings to stars based on grids of stellar models constrained by photome…

Rising from the Ashes II: The Bar-driven Abundance Bimodality of the Milky Way

Angus Beane, James Johnson, Vadim Semenov +3

The Milky Way hosts at least two modes in its present day distribution of Fe and alpha-elements. The exact cause of this bimodality is disputed, but one class of explanations invol…

The Impact of Classical Bulges on Stellar Bars and Box-Peanut-X-Features in Disk Galaxies

Rachel Lee McClure, Angus Beane, Elena D'Onghia +2

Galactic bars and their associated resonances play a significant role in shaping galaxy evolution. Resulting resonance-driven structures, like the vertically extended Boxy/Peanut X…
