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: Yi Zhou | First 5 Authors: Gao-Wei Qiu, Yi Zhou, , , | Summary: A sufficiently large parallel magnetic field will generate staggered supercurrent loops and superfluid density wave in two weakly linked superconducting (SC) ultrathin films, resulting in an inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state. The SC order parameter of such an FFLO state […]
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: Feng Wang | First 5 Authors: Xi Yang, Jie Zhang, Kejiang Chen, Weiming Zhang, Zehua Ma | Summary: Text content created by humans or language models is often stolen or misused by adversaries. Tracing text provenance can help claim the ownership of text content or identify the malicious users who distribute misleading content […]
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 […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Yuanhang Ning, Linhua Jiang, Zhen-Ya Zheng, Jin Wu, | Summary: We present a sample of Ly{alpha} emitters (LAEs) at $zapprox6.6$ from our spectroscopic survey of high-redshift galaxies using the multi-object spectrograph M2FS on the Magellan Clay telescope. The sample consists of 36 LAEs selected by the narrow-band […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Shu Wang, Linhua Jiang, Yue Shen, Luis C. Ho, Marianne Vestergaard | Summary: Broad line regions (BLRs) in high-redshift quasars provide crucial information of chemical enrichment in the early universe. Here we present a study of BLR metallicities in 33 quasars at redshift $5.7<z<6.4$. Using the near-IR […]
