Chongchitnan, S., & Hunt, M. (2017). On the abundance of extreme voids II : a survey of void mass functions. Journal of cosmology and astroparticle physics, 2017(03), doi:10.1088/1475-7516/2017/03/049. ISSN 1475-7516

The abundance of cosmic voids can be described by an analogue of halo mass functions for galaxy clusters. In this work, we explore a number of void mass functions: from those based on excursion-set theory to new mass functions obtained by modifying h... Read More

Constraining isocurvature perturbations with the 21 cm emission from minihaloes (2014)
Journal Article
Chongchitnan, S., & Takeuchi, Y. (2014). Constraining isocurvature perturbations with the 21 cm emission from minihaloes. Monthly notices of the Royal Astronomical Society, 439(1), (1125-1135). doi:10.1093/mnras/stu059. ISSN 1365-2966

We investigate the effects of isocurvature perturbations on the 21 cm radiation from minihaloes (MHs) at high redshifts and examine constraints on the isocurvature amplitude and power spectrum using the next generation of radio telescopes such as the... Read More
