Formation Channels of Diffuse Lights in Groups and Clusters over Time

open access: yesThe Astrophysical Journal
We explore the formation of the intragroup light and intracluster light, representing diffuse lights within groups and clusters, from the point that z = 1.5.

Galaxy Cluster Constraints on Extensions of Modified Gravity

open access: yesThe Astrophysical Journal
Modified Newtonian dynamics (MOND) has achieved notable success in explaining galaxy-scale phenomena and has made several unexpected, a priori predictions that align with observations.

Are the Galaxies with Indefinitely Flat Circular Velocities Located Inside Large Dark Matter Haloes?

open access: yesUniverse
A recent study using weak gravitational lensing revealed that the rotation curves of some isolated galaxies are found at a very large distance from their galactic centres. This may provide strong evidence supporting Modified Newtonian Dynamics (MOND) and

Tracing the Formation History of Intrahalo Light with Horizon Run 5

open access: yesThe Astrophysical Journal
We investigate the formation history of intrahalo light (IHL) using the high-resolution (∼1 kpc), large-scale (∼1 Gpc) cosmological hydrodynamical simulation Horizon Run 5 (HR5).
