Deep diving off the `Cosmic Cliffs': previously hidden outflows in NGC 3324 revealed by JWST

no code yet • 3 Oct 2022

We also identify several Herbig-Haro (HH) objects in Pa-$\alpha$ images from JWST; most are confirmed as jets based on their proper motions measured in a comparison with previous Hubble Space Telescope (HST) H$\alpha$ images.

Geopolitical Implications of a Successful SETI Program

no code yet • 29 Sep 2022

While we do not dispute that a realpolitik response is possible, we uncover concerns with W&T's presentation of the realpolitik paradigm, and we argue that sufficient reason is not given to justify treating this potential scenario as action-guiding over other candidate geopolitical responses.

Nuclear star cluster formation in star-forming dwarf galaxies

no code yet • 4 Oct 2022

Recent studies show that while low-mass NSCs in dwarf galaxies ($M_\text{gal} < 10^{9} M_\odot$) form predominantly out of the merger of globular clusters (GCs), high-mass NSCs in massive galaxies have assembled most of their mass through central enriched star formation.
