Kavli Affiliate: Jing Wang | First 5 Authors: Shaofu Xu, Jing Wang, Sicheng Yi, Weiwen Zou, | Summary: Tensor analytics lays mathematical basis for the prosperous promotion of multiway signal processing. To increase computing throughput, mainstream processors transform tensor convolutions to matrix multiplications to enhance parallelism of computing. However, such order-reducing transformation produces data duplicates […]

Kavli Affiliate: Ke Wang | First 5 Authors: Run Xiao, Jacob T Held, Jeffrey Rable, Supriya Ghosh, Ke Wang | Summary: Magnetic doping of topological quantum materials provides an attractive route for studying the effects of time-reversal symmetry breaking. Thus motivated, we explore the introduction of the transition metal Mn into thin films of the […]

Kavli Affiliate: Ran Wang | First 5 Authors: Jinyi Yang, Xiaohui Fan, Feige Wang, Giorgio Lanzuisi, Riccardo Nanni | Summary: We report X-ray observations of the most distant known gravitationally lensed quasar, J0439+1634 at $z=6.52$, which is also a broad absorption line (BAL) quasar, using the XMM-Newton Observatory. With a 130 ks exposure, the quasar […]

Kavli Affiliate: Feng Yuan | First 5 Authors: Changhua Bao, Haoyuan Zhong, Shaohua Zhou, Runfa Feng, Yuan Wang | Summary: Time- and angle-resolved photoemission spectroscopy (TrARPES) is a powerful technique for capturing the ultrafast dynamics of charge carriers and revealing photo-induced phase transitions in quantum materials. However, the lack of widely tunable probe photon energy, […]

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bingxiao Xu, Yingjie Peng, , , | Summary: We study the structural and environmental dependence of the star formation on the plane of stellar mass versus central core density ($Sigma_{rm 1 kpc}$) in the nearby universe. We study the central galaxies in the sparse environment and find […]

Kavli Affiliate: Subo Dong | First 5 Authors: Xiao-Jia Xie, Subo Dong, Yossi Shvartzvald, Andrew Gould, Andrzej Udalski | Summary: We constrain the host-star flux of the microlensing planet OGLE-2014-BLG-0676Lb using adaptive optics (AO) images taken by the Magellan and Keck telescopes. We measure the flux of the light blended with the microlensed source to […]

Kavli Affiliate: Subo Dong | First 5 Authors: Xiaojia Xie, Subo Dong, Wei Zhu, A. Gould, A. Udalski | Summary: We report adaptive-optics (AO) follow-up imaging of OGLE-2014-BLG-1050, which is the second binary microlensing event with space-based parallax measurements. The degeneracy in microlens parallax pi_E led to two sets of solutions, either a ~(0.9, 0.35) […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Wan-Min Zheng, Qiaoya Wu, Jianfeng Wu, Song Wang, Mouyuan Sun | Summary: The optical light curves of quiescent black hole low-mass X-ray binaries often exhibit significant non-ellipsoidal variabilities, showing the photospheric radiation of the companion star is veiled by other source of optical emission. Assessing this […]

Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shu Wang, Bing Zhang, Nobunari Kashikawa, Luis C. Ho | Summary: In Jiang et al., we detected a bright flash (hereafter GN-z11-flash) that appeared as compact continuum emission during our Keck MOSFIRE observations of the galaxy GN-z11 at z ~ 11. We performed a comprehensive […]

Kavli Affiliate: Linhua Jiang | First 5 Authors: Zhiwei Pan, Linhua Jiang, Xiaohui Fan, Jin Wu, Jinyi Yang | Summary: We present a well-designed sample of more than 1000 type 1 quasars at $3.5<z<5$ and derive UV quasar luminosity functions (QLFs) in this redshift range. These quasars were selected using the Sloan Digital Sky Survey […]
