Study of a 43 day optical quasi-periodic oscillation for BL Lac S5 0716+714
Lin Lu, Hao-Jing Zhang, Guo-Wei Ren
The data for BL Lac object S5 0716+714 optical B, R and I bands are collected from November 10, 2017 to May 15, 2018. The raw data consists of 21396 quasi-simultaneous multi-band p…
Detection of a high-confidence quasi-periodic oscillation in radio light curve of the high redshift FSRQ PKS J0805-0111
Guo-Wei Ren, Hao-Jing Zhang, Xiong Zhang +5
In this work, we have searched quasi-periodic oscillations (QPOs) in the 15 GHz light curve of the FSRQ PKS J0805-0111 monitored by the Owens Valley Radio Observatory (OVRO) 40 m t…
Non-Gaussianity in String Cosmology: A Case Study
Per Berglund, Guoqin Ren
We study non-gaussianity effects, using the formalism, in a multi-field inflationary model consisting of Kähler moduli derived from type IIB string compactification in the lar…
Multi-Field Inflation from String Theory
Per Berglund, Guoqin Ren
We construct a multi-field inflationary model consisting of multiple Kähler moduli derived from type IIB string compactification in the large volume limit. The model consists of bo…
