The effect of dark energy on the void-halo perpendicular alignments
Geonwoo Kang, Jounghun Lee
We report a numerical discovery that in a more rapidly accelerating spacetime, the galactic halos on void surfaces develop stronger perpendicular alignments with the directions tow…
How the cosmic voids contribute to stalling and quenching the giant galaxies on their surfaces
Geonwoo Kang, Jounghun Lee
We report a numerical hint that the formations of cosmic voids may be closely linked with the mechanism through which the giant galaxies on void surfaces establish elliptical shape…
A Universal Bilinear Model for the Dependence of Void Asymmetry Distributions on and
Geonwoo Kang, Jounghun Lee
: We present a new independent diagnostics based on void properties, by which the matter density parameter () and amplitude of initial density field () can be…
Void spin distribution as a powerful probe of
Geonwoo Kang, Jounghun Lee
We present a numerical proof of the concept that the void spin distributions can provide a tight constraint on the amplitude of matter density fluctuation on the scale of $8\,h^{-1…
