Comparison of MOND and Verlinde's emergent gravity in dwarf spheroidals
Youngsub Yoon, Sanghyeon Han, Ho Seong Hwang
We apply Modified Newtonian Dynamics (MOND) and Verlinde's emergent gravity separately to calculate the radial accelerations in 23 dwarf spheroidals. Then, we compare them with the…
Redshift Evolution of the Intrinsic Alignments of Early-Type Galaxies and Subhalos in the Horizon Run 5 Simulation
Sanghyeon Han, Motonari Tonegawa, Ho Seong Hwang +8
We investigate the redshift evolution of intrinsic alignments of the shapes of galaxies and subhalos with the large-scale structures of the universe using the cosmological hydrodyn…
Comment on "Emergent Gravity and the Dark Universe" by Erik Verlinde
Youngsub Yoon, Ho Seong Hwang
Verlinde suggested a new theory of gravity called ``emergent gravity,'' which resembles Modified Newtonian Dynamics, the alternative to dark matter theory. For his version of Milgr…
Diverse Rotation Curves of Galaxies in a Simulated Universe: the Observed Dependence on Stellar Mass and Morphology Reproduced
Daeun Jeong, Ho Seong Hwang, Haeun Chung +1
We use the IllustrisTNG cosmological hydrodynamical simulation to study the rotation curves of galaxies in the local universe. To do that, we first select the galaxies with 9.4 …
Understanding the Radial Acceleration Relation of Dwarf Galaxies with Emergent Gravity
Sanghyeon Han, Ho Seong Hwang, Youngsub Yoon
We examine whether the radial acceleration relation (RAR) of dwarf galaxies can be explained by Verlinde's emergent gravity. This is the extension of arXiv:2206.11685v3, which exam…
