JWST's Constraints on the Substellar IMF in NGC 2024
K. L. Luhman
The paper uses JWST NIRCam imaging and NIRSpec spectroscopy to identify brown dwarfs in the young cluster NGC 2024 and assesses whether the substellar initial mass function shows a…
Low-Metallicity Star Formation Survey in Sh2-284 (LZ-STAR): The Core Mass Function
Yu Cheng, Jonathan C. Tan, Morten Andersen +4
The authors use ALMA 1.3 mm dust continuum observations of the low‑metallicity star‑forming region Sh2‑284 to identify dense cores and measure the core mass function, finding a hig…
A tale of two isotopes: Spatial variation in HCN fractionation toward young cores
Sigurd S. Jensen, Silvia Spezzano, Olli Sipilä +3
The paper maps H13CN and HC15N in several young starless and pre‑stellar cores, finds that their column density ratio varies spatially and correlates with H2 column density, and sh…
SMGPS: A study of Galactic HII regions with extended morphology
Athanaseus J. T. Ramaila, Mark A. Thompson, Oleg M. Smirnov +7
The paper uses the MeerKAT 1.3 GHz Galactic Plane Survey to identify and characterize 1,327 Galactic H II regions, providing distances, Lyman‑photon fluxes, ionising star spectral…
How Should We Understand the Core Mass Function? A memo of the CMF2IMF conference at ESO Garching
Fengwei Xu, Roberto Galvan-Madrid, Kaho Morii +4
The paper reviews efforts to link the core mass function (CMF) to the stellar initial mass function (IMF), compiles observational core catalogs into a common framework via the publ…
Cradle of Life: From the Formation of Stars to Habitable Worlds with the SKAO
Eleonora Bianchi, Joseph R. Callingham, the Cradle of Life working group
The paper outlines how the Square Kilometre Array Observatory will be used to study the physical and chemical processes of star and planet formation, detect prebiotic molecules, ch…
