Cross Correlation between the Thermal Sunyaev-Zel'dovich Effect and Projected Galaxy Density Field
Ayodeji Ibitoye, Denis Tramonte, Yin-Zhe Ma +1
We present a joint analysis of the power spectra of the Planck Compton -parameter map and the projected galaxy density field using the Wide Field Infrared Survey Explorer (WISE)…
Recovering 21-cm signal from simulated FAST intensity maps
Elimboto Yohana, Yin-Zhe Ma, Di Li +2
The 21-cm intensity mapping (IM) of neutral hydrogen (HI) is a promising tool to probe the large-scale structures. Sky maps of 21-cm intensities can be highly contaminated by diffe…
Reconciling Hubble Constant Discrepancy from Holographic Dark Energy
Wei-Ming Dai, Yin-Zhe Ma, Hong-Jian He
Holographic dark energy (HDE) describes the vacuum energy in a cosmic IR region whose total energy saturates the limit of avoiding the collapse into a black hole. HDE predicts that…
How much primordial tensor mode is allowed?
Moumita Aich, Yin-Zhe Ma, Wei-Ming Dai +1
The presence of a significant amount of gravitational radiation in the early Universe affects the total energy density and hence the expansion rate in the early epoch. In this work…
Constraining the reionization history with CMB and spectroscopic observations
Wei-Ming Dai, Yin-Zhe Ma, Zong-Kuan Guo +1
We investigate the constraints on the reionization history of the Universe from a joint analysis of the cosmic microwave background and neutral hydrogen fraction data. The …
Lorentz invariance violation in the neutrino sector: a joint analysis from big bang nucleosynthesis and the cosmic microwave background
Wei-Ming Dai, Zong-Kuan Guo, Rong-Gen Cai +1
We investigate constraints on Lorentz invariance violation in the neutrino sector from a joint analysis of big bang nucleosynthesis and the cosmic microwave background. The effect…
Principal component analysis of the reionization history from Planck 2015 data
Wei-Ming Dai, Zong-Kuan Guo, Rong-Gen Cai
The simple assumption of an instantaneous reionization of the Universe may bias estimates of cosmological parameters. In this paper a model-independent principal component method f…
