From the top down and back up again: star cluster structure from hierarchical star formation. [PDF]
Mon Not R Astron Soc, 2018 Young massive star clusters spanning ~104-108M⊙ in mass have been observed to have similar surface brightness profiles. We show that recent hydrodynamical simulations of star cluster formation have also produced star clusters with this structure.

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010 Dynamical evolution plays a key role in shaping the current properties of star clusters and star cluster systems. A detailed understanding of the effects of evolutionary processes is essential to be able to disentangle the properties that result from dynamical evolution from those imprinted at the time of cluster formation.

The Milky Way’s nuclear star cluster: Old, metal-rich, and cuspy [PDF]
Astronomy & Astrophysics, 2020 Context. The environment of Sagittarius A* (Sgr A*), the central black hole of the Milky Way, is the only place in the Universe where we can currently study the interaction between a nuclear star cluster and a massive black hole and infer the properties ...

GW190412 as a Third-generation Black Hole Merger from a Super Star Cluster [PDF]
Astrophysical Journal, 2020 We explore the possibility that GW190412, a binary black hole merger with a non-equal-mass ratio and significantly spinning primary, was formed through repeated black hole mergers in a dense super star cluster.

The Astrophysical Journal, 2023 In protostellar cores, sulfur species are effective probes for the energetic environments, such as shocked regions. With the majority of sulfur depleted on dust grains, sulfur-bearing molecules could be liberated back to gas phase by shocks associated ...

The Astronomy and Astrophysics Review, 2020 AbstractWe 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 observational and theoretical works suggest that many NSC properties, including their masses, densities, and stellar populations, vary with the properties of their host ...

Modeling Dense Star Clusters in the Milky Way and beyond with the Cluster Monte Carlo Code [PDF]
Astrophysical Journal Supplement Series, 2021 We describe the public release of the Cluster Monte Carlo (CMC) code, a parallel, star-by-star N-body code for modeling dense star clusters. CMC treats collisional stellar dynamics using Hénon’s method, where the cumulative effect of many two-body ...

Nature Communications, 2023 Here the authors identify distinct mechanisms by which domain-specific p53 mutations activate cancer cell growth via the epidermal growth factor receptor (EGFR). These mechanisms affect sensitivity to EGFR inhibitors, opening avenues for targeted therapy.

A luminous X-ray outburst from an intermediate-mass black hole in an off-centre star cluster [PDF]
Nature Astronomy, 2018 A unique signature for the presence of massive black holes in very dense stellar regions is occasional giant-amplitude outbursts of multi-wavelength radiation from tidal disruption and subsequent accretion of stars that make a close approach to the black
