The DECam MAGIC Survey: Spectroscopic Follow-up of the Most Metal-Poor Stars in the Distant Milky Way Halo

Kavli Affiliate: Alexander P. Ji | First 5 Authors: Vinicius M. Placco, Guilherme Limberg, Anirudh Chiti, Deepthi S. Prabhu, Alexander P. Ji | Summary: In this work, we present high-resolution spectroscopic observations for six metal-poor stars with [Fe/H]<-3 (including one with [Fe/H]<-4), selected using narrow-band Ca II HK photometry from the DECam MAGIC Survey. The […]

Exact linear theory of perturbation response in a space- and feature-dependent cortical circuit model

Kavli Affiliate: Kenneth Miller | Authors: Ho Yin Chau, Kenneth D Miller and Agostina Palmigiano | Summary: What are the principles that govern the responses of cortical networks to their inputs and the emergence of these responses from recurrent connectivity? Recent experiments have probed these questions by measuring cortical responses to two-photon optogenetic perturbations of […]

XHEMTs on Ultrawide Bandgap Single-Crystal AlN Substrates

Kavli Affiliate: Grace Xing | First 5 Authors: Eungkyun Kim, Yu-Hsin Chen, Naomi Pieczulewski, Jimy Encomendero, David Anthony Muller | Summary: AlN has the largest bandgap in the wurtzite III-nitride semiconductor family, making it an ideal barrier for a thin GaN channel to achieve strong carrier confinement in field-effect transistors, analogous to silicon-on-insulator technology. Unlike […]

Disentangling Metallicity Effects in Hot Jupiter Occurrence Across Galactic Birth Radius and Phase-Space Density

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Rayna Rampalli, Melissa K. Ness, Elisabeth R. Newton, Andrew Vanderburg, Tobias Buck | Summary: We explore how the correlation between host star metallicity and giant planets shapes hot Jupiter occurrence as a function of Galactic birth radius (rbirth) and phase-space density in the Milky Way disk. Using […]

A genetic driver of epileptic encephalopathy impairs gating of synaptic glycolysis

Kavli Affiliate: Timothy A. Ryan | Authors: Zhanat Koshenov, Alexandros C. Kokotos, Lorena Benedetti, Jennifer Lippincott Schwartz and Timothy A. Ryan | Summary: The brain is a disproportionately large consumer of fuel, estimated to expend ∼20% of the whole-body energy budget, and therefore it is critical to adequately control brain fuel expenditures while satisfying its […]
