Probing Early Phases of the Epoch of Reionization with the Cross-Correlation
Wen-Qing Guo, Yin-Zhe Ma, Adam Lidz +2
Observations of the Epoch of Reionization (EoR) provide key insights into the nature of the first luminous sources and the thermal state of the intergalactic medium (IGM). Cross-co…
Cross-correlating Squared kSZ and HI Intensity Fields: A Map-level ACT--MeerKAT Forecast
Yu-Er Jiang, Yun Liu, Yan Gong +5
The kinetic Sunyaev--Zel'dovich (kSZ) effect probes the line-of-sight momentum of free electrons, but its blackbody spectrum and velocity-dependent sign make it difficult to isolat…
Constraining primordial non-Gaussianity and energy injection with the thermal Sunyaev-Zeldovich effect and integrated Sachs-Wolfe effect cross-correlation
Ayodeji Ibitoye, Yin-Zhe Ma, Prabhakar Tiwari
Constraining primordial non-Gaussianity (PNG) provides key insights into the physics of cosmic inflation and the initial conditions of the Universe, which remain central topics in…
Squared-field cross-correlation between kinetic Sunyaev-Zel'dovich effect and 21-cm intensity mapping
Zi-Yan Yuwen, Yu-Er Jiang, Yin-Zhe Ma +3
Neutral hydrogen (HI) 21-cm intensity mapping is an effective method to track the distribution of baryonic matter, and extract astrophysical and cosmological information. The 21-cm…
Cosmological Prediction from the joint observation of MeerKAT and CSST at = 0.4 1.2
Yu-Er Jiang, Yan Gong, Qi Xiong +10
Cross-correlating neutral hydrogen (HI) 21cm intensity mapping with galaxy surveys provides an effective probe of astrophysical and cosmological information. This work presents a c…
Cross-correlation of cosmic voids with thermal Sunyaev-Zel'dovich data
Gang Li, Yin-Zhe Ma, Denis Tramonte +1
We provide a measurement of the deficit in the Sunyaev-Zel'dovich Compton- signal towards cosmic voids, by stacking a catalogue of 97,090 voids constructed with BOSS-DR12 data,…
Cross-correlation between the thermal Sunyaev-Zeldovich effect and the Integrated Sachs-Wolfe effect
Ayodeji Ibitoye, Wei-Ming Dai, Yin-Zhe Ma +5
We present a joint cosmological analysis of the power spectra measurement of the Planck Compton parameter and the integrated Sachs-Wolfe (ISW) maps. We detect the statistical corre…
