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…
Expanding the SPISEA Stellar Population Synthesis Software to the Substellar Regime
Caitlin Begbie, Rachel Street, Katarzyna Kruszynska +4
The paper extends the SPISEA stellar population synthesis software to include brown dwarfs, providing updated substellar initial mass functions, atmospheric models, and evolutionar…
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…
The JADES Transient Survey III: Linking Core-Collapse Supernova Rates to Cosmic Star Formation
Christian Vassallo, Seppo Mattila, Christa DeCoursey +24
The paper uses JWST JADES transient survey data to compare core‑collapse supernova rates with cosmic star‑formation rate densities from redshift 0 to 5, exploring the impact of the…
