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 […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Minjung Park, Sandro Tacchella, Erica J. Nelson, Lars Hernquist, Rainer Weinberger | Summary: Observations have shown that the star-formation activity and the morphology of galaxies are closely related, but the underlying physical connection is not well understood. Using the TNG50 simulation, we explore the quenching and the […]
Kavli Affiliate: Yingjie Peng | First 5 Authors: Joanna M. Piotrowska, Asa F. L. Bluck, Roberto Maiolino, Yingjie Peng, | Summary: In this paper we investigate how massive central galaxies cease their star formation by comparing theoretical predictions from cosmological simulations: EAGLE, Illustris and IllustrisTNG with observations of the local Universe from the Sloan Digital […]
Kavli Affiliate: George R. Ricker | First 5 Authors: Rahul Jayaraman, Swetlana Hubrig, Daniel L. Holdsworth, Markus Schöller, Silva Järvinen | Summary: We report the detection and characterization of a new magnetospheric star, HD 135348, based on photometric and spectropolarimetric observations. The TESS light curve of this star exhibited variations consistent with stars known to […]
