Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Hillary D. Andales, Alexander P. Ji, Anna Frebel, Mohammad K. Mardini | Summary: The Milky Way has accreted many ultra-faint dwarf galaxies (UFDs), and stars from these galaxies can be found throughout our Galaxy today. Studying these stars provides insight into galaxy formation and early […]
Kavli Affiliate: Nicola Omodei | First 5 Authors: Jacco Vink, Dmitry Prokhorov, Riccardo Ferrazzoli, Patrick Slane, Ping Zhou | Summary: We report on a 5$sigma$ detection of polarized 3-6 keV X-ray emission from the supernova remnant Cassiopeia A with the Imaging X-ray Polarimetry Explorer (IXPE) mission. The overall polarization degree of 1.8 $pm$ 0.3% is […]
Kavli Affiliate: Subo Dong | First 5 Authors: Jian Ge, Hui Zhang, Weicheng Zang, Hongping Deng, Shude Mao | Summary: We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time, the occurrence rate and the orbital distributions of Earth-sized […]
Kavli Affiliate: Jing Wang | First 5 Authors: Wenxuan Wang, Chen Chen, Jing Wang, Sen Zha, Yan Zhang | Summary: For 3D medical image (e.g. CT and MRI) segmentation, the difficulty of segmenting each slice in a clinical case varies greatly. Previous research on volumetric medical image segmentation in a slice-by-slice manner conventionally use the […]
Kavli Affiliate: Tom Abel | First 5 Authors: Andrew Eberhardt, Michael Kopp, Tom Abel, , | Summary: We investigate the timescale on which quantum corrections alter the predictions of classical field theory for scalar field dark matter. This is accomplished by including second order terms in the evolution proportional to the covariance of the field […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Elisabeth R. Newton, Rayna Rampalli, Adam L. Kraus, Andrew W. Mann, Jason L. Curtis | Summary: The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of planetary evolution by providing new opportunities […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Elisabeth R. Newton, Rayna Rampalli, Adam L. Kraus, Andrew W. Mann, Jason L. Curtis | Summary: The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of planetary evolution by providing new opportunities to […]
Kavli Affiliate: T. Higuchi | First 5 Authors: F. Abudinén, I. Adachi, R. Adak, K. Adamczyk, L. Aggarwal | Summary: We report a measurement of the branching fraction of $B to K^{ast}(892)ell^+ell^-$ decays, where $ell^+ell^- = mu^+mu^-$ or $e^+e^-$, using electron-positron collisions recorded at an energy at or near the $Upsilon(4S)$ mass and corresponding to […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Yuming Fu, Xue-Bing Wu, Linhua Jiang, Yanxia Zhang, Zhi-Ying Huo | Summary: Quasars behind the Galactic plane (GPQs) are important astrometric references and valuable probes of the Galactic gas, yet the search of GPQs is difficult due to severe extinction and source crowding in the Galactic plane. […]
Kavli Affiliate: Feng Yuan | First 5 Authors: Hai Yang, Feng Yuan, Hui Li, Yosuke Mizuno, Fan Guo | Summary: The formation of jets in black hole accretion systems is a long-standing problem. It has been proposed that a jet can be formed by extracting the rotation energy of the black hole ("BZ-jet") or the […]
