Very Massive Stars and High N/O: A Tale of the Nitrogen-enriched Super Star Cluster in the Sunburst Arc

The Astrophysical Journal
The lensed Sunburst Arc ( z = 2.369) hosts a young (∼2–4 Myr), massive ( M _⋆  ∼ 10 ^7 M _⊙ ), compact ( R _eff  ∼ 8 pc) Lyman-continuum leaking super star cluster, which powers a compact (

Symmetry Breaking in Merging Binary Black Holes from Young Massive Clusters and Isolated Binaries

The Astrophysical Journal, 2023
Properties of the to-date observed binary black hole (BBH) merger events suggest a preference toward spin–orbit aligned mergers. Naturally, this has caused widespread interest and speculations regarding implications on various merger formation channels ...

Isolated massive star candidates in NGC 4242 with the Galaxy UV Legacy Project

Astronomy & Astrophysics
Context. There is considerable debate about the formation of massive stars, including whether a high-mass star must always form with a population of low-mass stars, or if it can also form in isolation.

GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

FEAST: A NIRSpec/MOS Survey of Emerging Young Star Clusters in NGC 628

The Astrophysical Journal
JWST can pierce through dusty molecular clouds to study the early stages of star formation, where young star clusters are actively driving stellar feedback and still emerging from their natal cloud.

OB runaway stars originating in the Vel OB1 association

Astronomy & Astrophysics
Context. OB runaway stars are massive stars moving through interstellar space with a high velocity (up to 200 km s−1). They are produced by dynamical ejections in young massive clusters or by supernova explosions in massive binaries.
