Surface Brightness Profile of Lyman-$α$ Halos out to 320 kpc in HETDEX

Posted by klaurent Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Maja Lujan Niemeyer, Eiichiro Komatsu, Chris Byrohl, Dustin Davis, Maximilian Fabricius | Summary: We present the median-stacked Lyman-$alpha$ surface brightness profile of 968 spectroscopically selected Lyman-$alpha$ emitting galaxies (LAEs) at redshifts $1.9<z<3.5$ in the early data of the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX). The selected LAEs […]

A Uniform Type Ia Supernova Distance Ladder with the Zwicky Transient Facility: Absolute Calibration Based on the Tip of the Red Giant Branch (TRGB) Method

Posted by klaurent Chicago

Kavli Affiliate: Wendy L. Freedman | First 5 Authors: Suhail Dhawan, Ariel Goobar, Joel Johansson, In Sung Jang, Mickael Rigault | Summary: The current Cepheid-calibrated distance ladder measurement of $H_0$ is reported to be in tension with the values inferred from the cosmic microwave background (CMB), assuming standard model cosmology. However, the tip of the […]

In situ architecture of the lipid transport protein VPS13C at ER-lysosomes membrane contacts

Posted by klaurent Yale

Kavli Affiliate: Pietro DeCamilli | Authors: Shujun Cai, Yumei Wu, Andres Guillen-Samander, William F Hancock-Cerutti, Jun Liu and Pietro De Camilli | Summary: VPS13 is a eukaryotic lipid transport protein localized at membrane contact sites. Previous studies suggested that it may transfer lipids between adjacent bilayers by a bridge-like mechanism. Direct evidence for this hypothesis […]

GaitStrip: Gait Recognition via Effective Strip-based Feature Representations and Multi-Level Framework

Posted by klaurent UCAS

Kavli Affiliate: Zheng Zhu | First 5 Authors: Ming Wang, Beibei Lin, Xianda Guo, Lincheng Li, Zheng Zhu | Summary: Many gait recognition methods first partition the human gait into N-parts and then combine them to establish part-based feature representations. Their gait recognition performance is often affected by partitioning strategies, which are empirically chosen in […]

Probing squeezing for gravitational-wave detectors with an audio-band field

Posted by klaurent MIT

Kavli Affiliate: Lisa Barsotti | First 5 Authors: Dhruva Ganapathy, Victoria Xu, Wenxuan Jia, Chris Whittle, Maggie Tse | Summary: Squeezed vacuum states are now employed in gravitational-wave interferometric detectors, enhancing their sensitivity and thus enabling richer astrophysical observations. In future observing runs, the detectors will incorporate a filter cavity to suppress quantum radiation pressure […]

Towards performant and reliable undersampled MR reconstruction via diffusion model sampling

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Pengfei Guo, S. Kevin Zhou, Vishal Patel, Rama Chellappa | Summary: Magnetic Resonance (MR) image reconstruction from under-sampled acquisition promises faster scanning time. To this end, current State-of-The-Art (SoTA) approaches leverage deep neural networks and supervised training to learn a recovery model. While these approaches […]
