Very Large Array imaging rules out precessing radio jets in three DESSDSS-selected candidate periodic quasars
Yu-Ching Chen, Xin Liu, Wei-Ting Liao +1
Periodic quasars have been suggested as candidates for hosting binary supermassive black holes (SMBHs), although alternative scenarios remain possible to explain the optical light…
Candidate Periodically Variable Quasars from the Dark Energy Survey and the Sloan Digital Sky Survey
Yu-Ching Chen, Xin Liu, Wei-Ting Liao +62
Periodically variable quasars have been suggested as close binary supermassive black holes. We present a systematic search for periodic light curves in 625 spectroscopically confir…
Discovery of a Candidate Binary Supermassive Black Hole in a Periodic Quasar from Circumbinary Accretion Variability
Wei-Ting Liao, Yu-Ching Chen, Xin Liu +68
Binary supermassive black holes (BSBHs) are expected to be a generic byproduct from hierarchical galaxy formation. The final coalescence of BSBHs is thought to be the loudest gravi…
Large Scale Dynamo in a Primordial Accretion Flow -- An Interpretation from Hydrodynamic Simulation
Wei-Ting Liao, Matthew Turk, Hsi-Yu Schive
Without an existing large scale coherent magnetic field in the early Universe, Population III (PopIII) stars would likely rotate at or near break-up speed. In this work, focusing o…
Fragmentation in a Primordial Accretion Flow
Wei-Ting Liao, Matthew Turk
Under rapid cooling from molecular hydrogen, the accretion disks around Population III (PopIII) stars are believed to fragment, resulting in multiple accreting cores. In this paper…
Spectral Energy Distributions of Candidate Periodically-Variable Quasars: Testing the Binary Black Hole Hypothesis
Hengxiao Guo, Xin Liu, Zafar Tayyaba +1
Periodic quasars are candidates for binary supermassive black holes (BSBHs) efficiently emitting low frequency gravitational waves. Recently, 150 candidates were identified f…
A hot big bang theory: magnetic fields and the early evolution of the protolunar disk
Charles F. Gammie, Wei-Ting Liao, Paul M. Ricker
The leading theory for the formation of the Earth's moon invokes a collision between a Mars-sized body and the proto-Earth to produce a disk of orbiting material that later condens…
Near-infrared H2 and Continuum Survey of Extended Green Objects. II. Complete Census for the Northern Galactic Plane
Hsu-Tai Lee, Wei-Ting Laio, Dirk Froebrich +7
We discuss 94 Extended Green Objects (EGOs) in the northern Galactic plane cataloged by Cyganowski et al, based on near-infrared narrowband H2 (2.122 μm and continuum observations…
Near-Infrared H2 and Continuum Survey of Extended Green Objects
Hsu-Tai Lee, Michihiro Takami, Hao-Yuan Duan +5
The Spitzer GLIMPSE survey has revealed a number of "Extended Green Objects" (EGOs) which display extended emission at 4.5 micron. These EGOs are potential candidates for high mass…
