On using inspiralling supermassive binary black holes in the PTA frequency band as standard sirens to constrain dark energy
Changshuo Yan, Wen Zhao, Youjun Lu
Supermassive binary black holes (SMBBHs) in galactic centers may radiate gravitational wave (GW) in the nano-Hertz frequency band, which are expected to be detected by pulsar timin…
Gravitational wave forms, polarizations, response functions and energy losses of triple systems in Einstein-Aether theory
Kai Lin, Xiang Zhao, Chao Zhang +7
Gravitationally bound hierarchies containing three or more components are very common in our Universe. In this paper we study {\em periodic} gravitational wave (GW) form, their pol…
Broad Balmer Absorption Line Variability: Evidence of Gas Transverse Motion in the QSO SDSS J125942.80+121312.6
Xiheng Shi, Hongyan Zhou, Xinwen Shu +6
We report on the discovery of broad Balmer absorption lines variability in the QSO SDSS J125942.80+121312.6, based on the optical and near-infrared spectra taken from the SDSS-I, S…
A Comprehensive Study of Broad Absorption Line Quasars: I. Prevalence of HeI* Absorption Line Multiplets in Low-Ionization Objects
Wen-Juan Liu, Hongyan Zhou, Tuo Ji +13
Neutral Helium multiplets, HeI*3189,3889,10830 are very useful diagnostics to the geometry and physical conditions of the absorbing gas in quasars. So far only a handful of HeI* de…
