Milky Way-est: Cosmological Zoom-in Simulations with Large Magellanic Cloud and Gaia-Sausage-Enceladus Analogs

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Deveshi Buch, Ethan O. Nadler, Risa H. Wechsler, Yao-Yuan Mao, | Summary: We present Milky Way-est, a suite of 20 cosmological cold-dark-matter-only zoom-in simulations of Milky Way (MW)-like host halos. Milky Way-est hosts are selected such that they: ($i$) are consistent with the MW’s measured halo […]

Photon Counting Interferometry to Detect Geontropic Space-Time Fluctuations with GQuEST

Kavli Affiliate: Lee McCuller | First 5 Authors: Sander M. Vermeulen, Torrey Cullen, Daniel Grass, Ian A. O. MacMillan, Alexander J. Ramirez | Summary: The GQuEST (Gravity from the Quantum Entanglement of Space-Time) experiment uses tabletop-scale Michelson laser interferometers to probe for fluctuations in space-time. We present a practicable interferometer design featuring a novel photon […]

Geometric deformation and redshift structure caused by plane gravitational waves

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Chao-Jun Feng, , , | Summary: The curved spacetime induced by gravitational waves can give rise to visual effects such as geometric distortions and redshift structures in the observed image. By establishing a mapping from the object’s surface coordinates to the observer’s screen coordinates, we […]

Ultra-high density electrodes improve detection, yield, and cell type identification in neuronal recordings

Kavli Affiliate: Xiaoqin Wang | Authors: Liam Paninski and Nathaniel Sawtell | Summary: To understand the neural basis of behavior, it is essential to sensitively and accurately measure neural activity at single neuron and single spike resolution. Extracellular electrophysiology delivers this, but it has biases in the neurons it detects and it imperfectly resolves their […]

Tonotopic organization of auditory cortex in awake marmosets revealed by multi-modal wide-field optical imaging

Kavli Affiliate: Xiaoqin Wang | Authors: Xindong Song, Yueqi Guo, Chenggang Chen, Jong Hoon Lee and Xiaoqin Wang | Summary: Tonotopic organization of the auditory cortex has been extensively studied in many mammalian species using various methodologies and physiological preparations. Tonotopy mapping in primates, however, is more limited due to constraints such as cortical folding, […]
