An Observed Transition of Galaxy Spins on the Void Surfaces

Jounghun Lee, Jun-Sung Moon

In the linear theory, the galaxy angular momentum vectors which originate from the initial tidal interactions with surrounding matter distribution intrinsically develop perpendicul…

Reoriented Memory of Galaxy Spins for the Early Universe

Jun-Sung Moon, Jounghun Lee

Galaxy spins are believed to retain the initially acquired tendency of being aligned with the intermediate principal axes of the linear tidal field, which disseminates a prospect o…

The Density Parity Model for the Evolution of the Subhalo Inner Spin Alignments with the Cosmic Web

Jun-Sung Moon, Jounghun Lee

We develop a new model within which the radius-dependent transition of the subhalo inner spins with respect to the cosmic web and the variation of the transition threshold radius (…

Radius-Dependent Spin Transition of Dark Matter Halos

Jun-Sung Moon, Jounghun Lee

A numerical detection of the radius-dependent spin transition of dark matter halos is reported. Analyzing the data from the IllustrisTNG simulations, we measure the halo spin vecto…

Combined Effects of Gravity and Massive Neutrinos on the Turn-Around Radii of Dark Matter Halos

Jounghun Lee, Marco Baldi

We present a new statistics based on the turn-around radii of cluster halos to break the dark sector degeneracy between the CDM model and the alternative ones with gravit…

The Splashback Mass Function in the Presence of Massive Neutrinos

Suho Ryu, Jounghun Lee

We present a complementary methodology to constrain the total neutrino mass, , based on the diffusion coefficient of the splashback mass function of dark matter halos. An…
