Low-Surface-Brightness Galaxies are missing in the observed Stellar Mass Function
Juhan Kim, Jaehyun Lee, Clotilde Laigle +8
We investigate the impact of the surface brightness (SB) limit on the galaxy stellar mass functions (GSMFs) using mock surveys generated from the Horizon Run 5 (HR5) simulation. We…
Minkowski Tensors in Redshift Space -- Beyond the Plane Parallel Approximation
Stephen Appleby, Joby P. Kochappan, Pravabati Chingangbam +1
The Minkowski tensors (MTs) can be used to probe anisotropic signals in a field, and are well suited for measuring the redshift space distortion (RSD) signal in large scale structu…
The Fundamental Plane Is Not a Plane: Warped Nature of the Fundamental Plane of Early-type Galaxies and Its Implication for Galaxy Formation
Yongmin Yoon, Changbom Park
Based on early-type galaxies (ETGs) in from Sloan Digital Sky Survey data, we show that the fundamental plane (FP) of ETGs is not a plane…
The first direct measurement of gravitational potential decay rate at cosmological scales and improved dark energy constraint
Fuyu Dong, Pengjie Zhang, Zeyang Sun +1
The integrated Sachs-Wolfe (ISW) effect probes the decay rate () of large scale gravitational potential and therefore provides unique constraint on dark energy (DE). However it…
Formation and Morphology of the First Galaxies in the Cosmic Morning
Changbom Park, Jaehyun Lee, Juhan Kim +8
We investigate the formation and morphological evolution of the first galaxies in the cosmic morning () using the Horizon Run 5 (HR5) simulation. For galaxi…
