The DECam MAGIC Survey: A Wide-field Photometric Metallicity Study of the Sculptor Dwarf Spheroidal Galaxy

Posted by klaurent Chicago

Kavli Affiliate: Alexander Ji | First 5 Authors: Fabrícia O. Barbosa, Anirudh Chiti, Guilherme Limberg, Andrew Pace, William Cerny | Summary: The metallicity distribution function and internal chemical variations of a galaxy are fundamental to understand its formation and assembly history. In this work, we analyze photometric metallicities for 3883 stars over seven half-light radii […]

HumanDreamer-X: Photorealistic Single-image Human Avatars Reconstruction via Gaussian Restoration

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Boyuan Wang, Runqi Ouyang, Xiaofeng Wang, Zheng Zhu, Guosheng Zhao | Summary: Single-image human reconstruction is vital for digital human modeling applications but remains an extremely challenging task. Current approaches rely on generative models to synthesize multi-view images for subsequent 3D reconstruction and animation. However, directly generating […]

Recursive Training Loops in LLMs: How training data properties modulate distribution shift in generated data?

Posted by dbos MIT

Kavli Affiliate: Peter Ford | First 5 Authors: Grgur Kovač, Jérémy Perez, Rémy Portelas, Peter Ford Dominey, Pierre-Yves Oudeyer | Summary: Large language models (LLMs) are increasingly contributing to the creation of content on the Internet. This creates a feedback loop as subsequent generations of models will be trained on this generated, synthetic data. This […]

Evidence for Charge Exchange Emission in Supernova Remnant N132D from XRISM/Resolve Observations

Posted by klaurent MIT

Kavli Affiliate: Eric D. Miller | First 5 Authors: Liyi Gu, Hiroya Yamaguchi, Adam Foster, Satoru Katsuda, Hiroyuki Uchida | Summary: XRISM has delivered one of its first light observations on N132D, the X-ray brightest supernova remnant in the Large Magellanic Cloud. Utilizing 193 ks of high-resolution X-ray spectroscopy data, we conduct a comprehensive search […]

JACUZI-SD: An automated, high-throughput, minimally stressful approach to sleep depriving larval zebrafish

Posted by klaurent Hopkins

Kavli Affiliate: Seth Blackshaw | Authors: Leah J Elias, Harrison Khoo, Francois Kroll, Caroline Zhang, Soojung C Hur, Jason Rihel and Seth Blackshaw | Summary: While sleep deprivation broadly disrupts health and well-being, the neural and molecular mechanisms that signal increased sleep pressure remain poorly understood. A key obstacle to progress is the fact that […]

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

Posted by klaurent Yale

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 […]

Supersizing hydrodynamical simulations of reionization using perturbative techniques

Posted by klaurent MIT

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 […]
