OTI on FIRE: Testing the Efficacy of Orbital Torus Imaging to Recover the Galactic Potential

Kavli Affiliate: Lina Necib | First 5 Authors: Micah Oeur, Sarah R. Loebman, Adrian M. Price-Whelan, Arpit Arora, Lina Necib | Summary: Orbital Torus Imaging (OTI) is a dynamical inference method for determining the Milky Way’s gravitational potential using stellar survey data. OTI uses gradients in stellar astrophysical quantities, such as element abundances, as functions […]

The THESAN-ZOOM project: Star formation efficiency from giant molecular clouds to galactic scale in high-redshift starbursts

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zihao Wang, Xuejian Shen, Mark Vogelsberger, Hui Li, Rahul Kannan | Summary: Star formation in galaxies is inherently complex, involving the interplay of physical processes over a hierarchy of spatial scales. In this work, we investigate the connection between global (galaxy-scale) and local (cloud-scale) star formation efficiencies […]

The Eccentricity Distribution of Warm Sub-Saturns in TESS

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang, Emma Nabbie, George Zhou | Summary: We present the eccentricity distribution of warm sub-Saturns (4-8 Re, 8-200 day periods) as derived from an analysis of transit light curves from NASA’s Transiting Exoplanet Survey Satellite (TESS) mission. We use the […]

Probing Abundance Variations among Multiple Stellar Populations in the Metal-Poor Globular Cluster NGC 2298 using Gemini-South/GHOST

Kavli Affiliate: Anna Frebel | First 5 Authors: Avrajit Bandyopadhyay, Rana Ezzeddine, Vinicius M. Placco, Anna Frebel, David S Aguado | Summary: Studying the abundances in metal-poor globular clusters is crucial for understanding the formation of the Galaxy and the nucleosynthesis processes in the early Universe. We observed 13 red giant stars from the metal-poor […]
