Kavli Affiliate: Anna Frebel | First 5 Authors: Kaitlin C. Rasmussen, Joseph Zepeda, Timothy C. Beers, Vinicius M. Placco, Eric Depagne | Summary: We present the first release of a large-scale study of relatively bright (V < 13.5) metal-poor stars observed with the Southern African Large Telescope (SALT), based on high-resolution spectra of 50 stars […]
Kavli Affiliate: R. Morris | First 5 Authors: Jesus M. Salas, Smadar Naoz, Mark R. Morris, , | Summary: The gas dynamics in the inner few kiloparsecs of barred galaxies often results in configurations that give rise to nuclear gas rings. However, the generic dynamical description of the formation of galactic nuclear rings does not […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Simone Giacomelli, Mario Martone, Yuji Tachikawa, Gabi Zafrir, | Summary: We carry out a systematic study of 4d $mathcal{N} = 2$ preserving S-folds of F-theory 7-branes and the worldvolume theories on D3-branes probing them. They consist of two infinite series of theories, which we denote following the […]
Kavli Affiliate: Ke Wang | First 5 Authors: Zhenlong Xu, Ziqi Xu, Jixue Liu, Debo Cheng, Jiuyong Li | Summary: The increasing application of machine learning techniques in everyday decision-making processes has brought concerns about the fairness of algorithmic decision-making. This paper concerns the problem of collider bias which produces spurious associations in fairness assessment […]
Kavli Affiliate: David A. Principe | First 5 Authors: Amit Kashi, David A. Principe, Noam Soker, Joel H. Kastner, | Summary: The massive binary system Eta Carinae is characterized by intense colliding winds that form shocks and emit X-rays. The system is highly eccentric ($esimeq0.9$), resulting in modulated X-ray emission during its 5.54 year orbit. […]
