The Alcock Paczynski test with 21cm intensity field
Takao Endo, Hiroyuki Tashiro, Atsushi J. Nishizawa
Feasibility of the Alcock Paczynski (AP) test by stacking voids in the 21cm line intensity field is presented. We analyze the Illstris-TNG simulation to obtain the 21cm signal map.…
Effect of Dark Energy Perturbation on Cosmic Voids Formation
Takao Endo, Atsushi J. Nishizawa, Kiyotomo Ichiki
In this paper, we present the effects of dark energy perturbation on the formation and abundance of cosmic voids. We consider dark energy to be a fluid with a negative pressure cha…
