Diversity and universality: evolution of dwarf galaxies with self-interacting dark matter
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +4
Dark matter halos with self-interacting dark matter (SIDM) experience a unique evolutionary phenomenon, in that their central regions eventually collapse to high density through th…
Till the core collapses: the evolution and properties of self-interacting dark matter subhalos
Zhichao Carton Zeng, Annika H. G. Peter, Xiaolong Du +6
One of the hottest questions in the cosmology of self-interacting dark matter (SIDM) is whether scatterings can induce detectable core-collapse in halos by the present day. Because…
Calibrating the SIDM Gravothermal Catastrophe with N-body Simulations
Charlie Mace, Shengqi Yang, Zhichao Carton Zeng +3
Self-interacting dark matter (SIDM) theories predict that dark matter halos experience core-collapse in late-stage evolution, a process where the halo's inner region rapidly increa…
A New Framework for ISM Emission Line Models: Connecting Multi-Scale Simulations Across Cosmological Volumes
Shengqi Yang, Adam Lidz, Andrew Benson +7
The JWST and ALMA have detected emission lines from the ionized interstellar medium (ISM) in some of the first galaxies at . These measurements present an opportunity…
Do cosmological simulations reproduce the [OIII] 88 m line emission and properties of JWST-discovered galaxies at ?
Shengqi Yang, Adam Lidz, Hui Li +3
Recent ALMA observations of the [OIII] 88 m line provide spectroscopic confirmation of two JWST photometric candidates, GS-z14 and GHZ2, at and , respectively.…
Bacterial dimensions sensitively regulate surface diffusivity and residence time
Premkumar Leishangthem, Xuan Wang, Junan Chen +2
Run-and-tumble is a common but vital strategy that bacteria employ to explore environment suffused with boundaries, as well as to escape from entrapment. In this study we reveal ho…
