XraySyn: Realistic View Synthesis From a Single Radiograph Through CT Priors

Posted by klaurent UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Cheng Peng, Haofu Liao, Gina Wong, Jiebo Luo, Shaohua Kevin Zhou | Summary: A radiograph visualizes the internal anatomy of a patient through the use of X-ray, which projects 3D information onto a 2D plane. Hence, radiograph analysis naturally requires physicians to relate the prior about 3D […]

Nonthermal electron and ion acceleration by magnetic reconnection in large laser-driven plasmas

Posted by klaurent Stanford

Kavli Affiliate: Tom Abel | First 5 Authors: Samuel Totorica, Masahiro Hoshino, Tom Abel, Frederico Fiuza, | Summary: Magnetic reconnection is a fundamental plasma process that is thought to play a key role in the production of nonthermal particles associated with explosive phenomena in space physics and astrophysics. Experiments at high-energy-density facilities are starting to […]

An extended halo around an ancient dwarf galaxy

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Anirudh Chiti, Anna Frebel, Joshua D. Simon, Denis Erkal, Laura J. Chang | Summary: The Milky Way is surrounded by dozens of ultra-faint (< $10^5$ solar luminosities) dwarf satellite galaxies. They are the surviving remnants of the earliest galaxies, as confirmed by their ancient (~13 billion years […]

Cosmic-Ray Diffusion Suppression in Star-forming Regions Inhibits Clump Formation in Gas-rich Galaxies

Posted by klaurent Chicago

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: , , , , | Summary: Observations of the $gamma$-ray emission around star clusters, isolated supernova remnants, and pulsar wind nebulae indicate that the cosmic-ray (CR) diffusion coefficient near acceleration sites can be suppressed by a large factor compared to the Galaxy average. We explore the […]
