A short review on Quintom dark energy theory
Xin Ren, Si-Yu Li, Yang Liu +3
In this paper, we provide a short review on the Quintom dark energy theory. Firstly, we discuss the No-Go theorem associated with dynamical dark energy, then present some examples…
Study the nature of dynamical dark energy by measuring the CMB polarization rotation angle
Hua Zhai, Si-Yu Li, Yang Liu +6
Recent results from the Dark Energy Spectroscopic Instrument (DESI) support the dynamical dark energy. Intriguingly, the data favor a transition of the dark energy equation of stat…
Forecasts of CMB lensing reconstruction of AliCPT-1 from the foreground cleaned polarization data
Jiakang Han, Bin Hu, Shamik Ghosh +14
Cosmic microwave background radiation (CMB) observations are unavoidably contaminated by emission from various extra-galactic foregrounds, which must be removed to obtain reliable…
CMB polarization analysis on circular scans
Jia-Rui Li, Chunlong Li, Jie Jiang +4
Most cosmic microwave background experiments observe the sky along circular or near-circular scans on the celestial sphere. For such experiments, we show that simple linear systems…
The design of the Ali CMB Polarization Telescope receiver
Maria Salatino, Jason E. Austermann, Keith L. Thompson +72
Ali CMB Polarization Telescope (AliCPT-1) is the first CMB degree-scale polarimeter to be deployed on the Tibetan plateau at 5,250m above sea level. AliCPT-1 is a 90/150 GHz 72 cm…
The effects on CMB power spectra and bispectra from the polarization rotation and its correlations with temperature and E-polarization
Hua Zhai, Si-Yu Li, Mingzhe Li +2
The Chern-Simons term, through which the cosmic Axion-like field couples to the electromagnetic field, has the effect to rotate CMB polarization directions and to break the CPT sym…
