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…

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…

Primordial Black Holes from Primordial Voids

Cristian Joana, Zi-Yan Yuwen

Primordial black holes (PBHs) are a compelling dark matter candidate and a unique probe of small-scale cosmological fluctuations. Their formation is usually attributed to large pos…
