Kavli Affiliate: Huawei Zhang | First 5 Authors: Fangzhou Ren, Richard de Grijs, Huawei Zhang, Licai Deng, Xiaodian Chen | Summary: We present a catalog of eclipsing binaries in the northern Galactic Plane from the Kiso Wide-Field Camera Intensive Survey of the Galactic Plane (KISOGP). We visually identified 7055 eclipsing binaries spread across $sim$330 square […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Linhua Jiang, Shu Wang, Bing Zhang, Nobunari Kashikawa, Luis C. Ho | Summary: In Jiang et al. (2020), we reported a possible bright flash (hereafter GN-z11-flash) from a galaxy GN-z11 at z ~ 11. Recently, Steinhardt et al. (2021; arXiv:2101.12738) found 27 images with transient signals in […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Yang Huang, Haibo Yuan, Timothy C. Beers, Huawei Zhang, | Summary: We present an independent examination of the parallax zero-point of the Third Gaia Early Data Release (hereafter EDR3), using the LAMOST primary red clump (PRC) stellar sample. A median parallax offset of around $26 mu$as, slightly […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Jamila Pegues, Ian Czekala, Sean M. Andrews, Karin I. Öberg, Gregory J. Herczeg | Summary: In this era of Gaia and ALMA, dynamical stellar mass measurements provide benchmarks that are independent of observations of stellar characteristics and their uncertainties. These benchmarks can then be used to […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Xuhao Wu, Shishao Bao, Hong Shen, Renxin Xu, | Summary: The secondary component of GW190814 with a mass of 2.50-2.67 $M_{odot}$ may be the lightest black hole or the heaviest neutron star ever observed in a binary compact object system. To explore the possible equation of state […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Feige Wang, Jinyi Yang, Xiaohui Fan, Joseph F. Hennawi, Aaron J. Barth | Summary: Distant quasars are unique tracers to study the formation of the earliest supermassive black holes (SMBHs) and the history of cosmic reionization. Despite extensive efforts, only two quasars have been found at $zge7.5$, […]
Kavli Affiliate: Ran Wang | First 5 Authors: Ran Wang, Yimin Xiao, , , | Summary: The generalized fractional Brownian motion (GFBM) $X:={X(t)}_{tge0}$ with parameters $gamma in [0, 1)$ and $alphain left(-frac12+frac{gamma}{2}, , frac12+frac{gamma}{2} right)$ is a centered Gaussian $H$-self-similar process introduced by Pang and Taqqu (2019) as the scaling limit of power-law shot noise […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Chun-Fan Liu, Hsien Shang, Gregory J. Herczeg, Frederick M. Walter, | Summary: Forbidden neon emission lines from small-scale microjets can probe high-energy processes in low-mass young stellar systems. We obtained spatially resolved [Ne III] spectra of the microjets from the classical T Tauri Star Sz 102 […]
Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Anupam Bhardwaj, Marina Rejkuba, Richard de Grijs, Soung-Chul Yang, Gregory J. Herczeg | Summary: We present new near-infrared, $JHK_s$, Period–Luminosity relations (PLRs) for RR Lyrae variables in the Messier 53 (M53 or NGC 5024) globular cluster. Multi-epoch $JHK_s$ observations, obtained with the WIRCam instrument on the […]
Kavli Affiliate: Fukun Liu | First 5 Authors: Xinwen Shu, Wenjie Zhang, Shuo Li, Ning Jiang, Liming Dou | Summary: Optical transient surveys have led to the discovery of dozens of stellar tidal disruption events (TDEs) by massive black hole in the centers of galaxies. Despite extensive searches, X-ray follow-up observations have produced no or […]
