Tie Liu, Qizhou Zhang, Kee-Tae Kim +37
We are performing a series of observations with ground-based telescopes toward Planck Galactic cold clumps (PGCCs) in the Orionis complex in order to systematically investigate…
Tachyon field theory description of (thermo)dynamics in dS space
Huiquan Li, J. X. Lu
In this work, we present a few pieces of evidence in support of a possible connection of the gravitational theory in dS space to the worldvolume theory of unstable D-branes. We sho…
The East-Asian VLBI Network
Kiyoaki Wajima, Yoshiaki Hagiwara, Tao An +14
The East-Asian VLBI Network (EAVN) is the international VLBI facility in East Asia and is conducted in collaboration with China, Japan, and Korea. The EAVN consists of VLBI arrays…
Investigation of intergranular bright points from the New Vacuum Solar Telescope
Kai-Fan Ji, Jian-ping Xiong, Yong-yuan Xiang +4
Six high-resolution TiO-band image sequences from the New Vacuum Solar Telescope (NVST) are used to investigate the properties of intergranular bright points (igBPs). We detect the…
Spitzer Microlensing Program as a Probe for Globular Cluster Planets. Analysis of OGLE-2015-BLG-0448
Radosław Poleski, Wei Zhu, Grant W. Christie +83
The microlensing event OGLE-2015-BLG-0448 was observed by Spitzer and lay within the tidal radius of the globular cluster NGC 6558. The event had moderate magnification and was int…
High-precision photometry by telescope defocussing. VIII. WASP-22, WASP-41, WASP-42 and WASP-55
John Southworth, J. Tregloan-Reed, M. I. Andersen +47
We present 13 high-precision and four additional light curves of four bright southern-hemisphere transiting planetary systems: WASP-22, WASP-41, WASP-42 and WASP-55. In the cases o…
A new method to measure the virial factors in the reverberation mapping of AGNs
H. T. Liu, H. C. Feng, J. M. Bai
Based on the gravitational redshift, one prediction of Einstein's general relativity theory, of broad optical emission lines in active galactic nuclei (AGNs), a new method is propo…
Discovery of two broad absorption line quasars at redshift about 4.75 using the Lijiang 2.4m telescope
WeiMin Yi, XueBing Wu, FeiGe Wang +3
The ultraviolet broad absorption lines have been seen in the spectra of quasars at high redshift, and are generally considered to be caused by outflows with velocities from thousan…
Analytic properties of force-free jets in the Kerr spacetime -- II
Zhen Pan, Cong Yu
We reinvestigate the structure of a steady axisymmetic force-free magnetosphere around a Kerr black hole (BH). The BH magnetosphere structure is governed by a second-order differen…
