Nuclear star clusters

N Neumayer, A Seth, T Böker - The Astronomy and Astrophysics Review, 2020 - Springer
We review the current knowledge about nuclear star clusters (NSCs), the spectacularly
dense and massive assemblies of stars found at the centers of most galaxies. Recent …

Star Clusters Near and Far: Tracing Star Formation Across Cosmic Time

A Adamo, P Zeidler, JMD Kruijssen, M Chevance… - Space Science …, 2020 - Springer

What causes the formation of discs and end of bursty star formation?

PF Hopkins, AB Gurvich, X Shen… - Monthly Notices of …, 2023 - academic.oup.com
As they grow, galaxies can transition from irregular/spheroidal with 'bursty'star formation
histories (SFHs), to discy with smooth SFHs. But even in simulations, the direct physical …

FIRE-3: updated stellar evolution models, yields, and microphysics and fitting functions for applications in galaxy simulations

PF Hopkins, A Wetzel, C Wheeler… - Monthly Notices of …, 2023 - academic.oup.com
Increasingly, uncertainties in predictions from galaxy formation simulations (at sub-Milky
Way masses) are dominated by uncertainties in stellar evolution inputs. In this paper, we …

Galaxies lacking dark matter produced by close encounters in a cosmological simulation

J Moreno, S Danieli, JS Bullock, R Feldmann… - Nature …, 2022 - nature.com
The standard cold dark matter plus cosmological constant model predicts that galaxies form
within dark-matter haloes, and that low-mass galaxies are more dark-matter dominated than …

Exploring the physical properties of lensed star-forming clumps at 2 ≲ z ≲ 6
