Fly navigational responses to odor motion and gradient cues are tuned to plume statistics

Kavli Affiliate: Damon Clark | Authors: Samuel Brudner, Baohua Zhou, Viraaj Jayaram, Gustavo Madeira Santana, Damon Clark and Thierry Emonet | Summary: Odor cues guide animals to food and mates. Different environmental conditions can create differently patterned odor plumes, making navigation more challenging. Prior work has shown that animals turn upwind when they detect odor […]

Core collapse in resonant self-interacting dark matter across two decades in halo mass

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Vinh Tran, , , | Summary: Core collapse, a process associated with self-interacting dark matter (SIDM) models, can increase the central density of halos by orders of magnitude with observable consequences for dwarf galaxy properties and gravitational lensing. Resonances in the self-interaction cross section, features […]

TDCOSMO XVII. New time delays in 22 lensed quasars from optical monitoring with the ESO-VST 2.6m and MPG 2.2m telescopes

Kavli Affiliate: R. G. McMahon | First 5 Authors: , , , , | Summary: We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope and Max-Planck-Gesellschaft 2.2 m telescope. Each lensed quasar was typically monitored […]

Supersizing hydrodynamical simulations of reionization using perturbative techniques

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Wenzer Qin, Katelin Schutz, Olivia Rosenstein, Stephanie O’Neil, Mark Vogelsberger | Summary: We show that perturbative techniques inspired by effective field theory (EFT) can be used to "paint on" the 21~cm field during reionization using only the underlying linear density field. This procedure is accurate to within […]

Ain’t no resonance high enough: Core collapse in self-interacting dark matter across two decades in halo mass

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Vinh Tran, Xuejian Shen, Daniel Gilman, Mark Vogelsberger, Stephanie O’Neil | Summary: Core collapse, a process associated with self-interacting dark matter (SIDM) models, can increase the central density of halos by orders of magnitude with observable consequences for dwarf galaxy properties and gravitational lensing. Resonances in the […]

Autonomous Human-Robot Interaction via Operator Imitation

Kavli Affiliate: David Muller | First 5 Authors: Sammy Christen, David Müller, Agon Serifi, Ruben Grandia, Georg Wiedebach | Summary: Teleoperated robotic characters can perform expressive interactions with humans, relying on the operators’ experience and social intuition. In this work, we propose to create autonomous interactive robots, by training a model to imitate operator data. […]

Enhancing Compton telescope imaging with maximum a posteriori estimation: a modified Richardson-Lucy algorithm for the Compton Spectrometer and Imager

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Hiroki Yoneda, Thomas Siegert, Israel Martinez-Castellanos, Savitri Gallego, Chris Karwin | Summary: We present a modified Richardson-Lucy (RL) algorithm tailored for image reconstruction in MeV gamma-ray observations, focusing on its application to the upcoming Compton Spectrometer and Imager (COSI) mission. Our method addresses key challenges in MeV […]
