Blind source separation of the stellar halo

Autor: Davies, Elliot Y., Belokurov, Vasily, Kravtsov, Andrey, Monty, Stephanie, Myeong, GyuChul, Evans, N. Wyn, Kane, Sarah G.

The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and \textit{in-situ} evolution, that form an interweaving tapestry in kinematic space. To untangle this, we consider the mixtures of chemical inform

Predicting metallicities and carbon abundances from Gaia XP spectra for (carbon-enhanced) metal-poor stars

Autor: Ardern-Arentsen, Anke, Kane, Sarah G., Belokurov, Vasily, Matsuno, Tadafumi, Montelius, Martin, Monty, Stephanie, Sanders, Jason L.

Carbon-rich (C-rich) stars can be found at all metallicities and evolutionary stages. They are often the result of mass-transfer from a companion, but some of the most metal-poor C-rich objects are likely carrying the imprint of the metal-free First

The Ones That Got Away: Chemical Tagging of Globular Cluster-Origin Stars with Gaia BP/RP Spectra

Autor: Kane, Sarah G., Belokurov, Vasily, Cranmer, Miles, Monty, Stephanie, Zhang, Hanyuan, Ardern-Arentsen, Anke, Kane, Elana

Globular clusters (GCs) are sites of extremely efficient star formation, and recent studies suggest they significantly contributed to the early Milky Way's stellar mass build-up. Although their role has since diminished, GCs' impact on the Galaxy's i

Kinematics and dynamics of the Galactic bar revealed by Gaia long-period variables

Autor: Zhang, Hanyuan, Belokurov, Vasily, Evans, N. Wyn, Kane, Sarah G., Sanders, Jason L.

We use low-amplitude, long period variable (LA-LPV) candidates in \textit{Gaia} DR3 to trace the kinematics and dynamics of the Milky Way bar. LA-LPVs, like other LPVs, are intrinsically bright and follow a tight period-luminosity relation, but unlik

A Universe of Sound: Processing NASA Data into Sonifications to Explore Participant Response

Autor: Arcand, Kimberly K., Schonhut-Stasik, Jessica S., Kane, Sarah G., Sturdevant, Gwynn, Russo, Matt, Watze, Megan, Hsu, Brian, Smith, Lisa F.

Historically, astronomy has prioritized visuals to present information, with scientists and communicators overlooking the critical need to communicate astrophysics with blind or low-vision audiences and provide novel channels for sighted audiences to
