In this paper, we provide a highly accurate value for the binding energy of benzene to proton-ordered crystalline water ice (XIh), as a model for interstellar ices. We compare our computed value to the latest experimental data available from temperat... Read More about Hybrid approach predicts a lower binding energy for benzene on water ice.

We investigate the formation and morphological evolution of the first galaxies in the cosmic morning (10 ≳ z ≳ 4) using the Horizon Run 5 (HR5) simulation. For galaxies above the stellar mass M ⋆ , min = 2 × 10 9 M ⊙ , we classify them into disk, sph... Read More about Formation and Morphology of the First Galaxies in the Cosmic Morning.

Resilience of sloshing cold fronts against subsequent minor mergers (2022)
Journal Article

Minor mergers are common in galaxy clusters. They have the potential to create sloshing cold fronts (SCFs) in the intracluster medium of the cluster. However, the resilience of SCFs to subsequent minor mergers is unknown. Here we investigate the exte... Read More about Resilience of sloshing cold fronts against subsequent minor mergers.

We studied α cluster states in Mg26 via the Ne22(Li6,dγ)Mg26 reaction in inverse kinematics at an energy of 7 MeV/nucleon. States between Ex = 4-14 MeV in Mg26 were populated and relative α spectroscopic factors were determined. Some of these states...
