Bubbles resulting from outflowing material colliding with surrounding material appear to be ubiquitous in young stars, and researchers have developed a framework to understand the kinematic signatures of these structures.

Sierra L. Grant et al 2023 ApJL 947 L6

Precise spectroscopy with JWST has enabled the detection of faint spectral lines from various molecules in the protoplanetary disk GW Lupii, facilitating the first detection of ¹³CO₂ in a planet-forming disk.

Allison K. Glantzberg et al 2023 Planet. Sci. J. 4 107

Comparison of modeling and observations shows that crater interiors suggested by models to be permanently shadowed, suggestive of the presence of ice, are correlated with regions of high radar backscatter.

A chance alignment of a background elliptical galaxy and a foreground face-on spiral galaxy gives researchers a unique chance to study the galaxy’s dust properties and distribution.

Stephanie M. LaMassa et al 2023 ApJ 944 152

New research has dredged up three examples of radio-loud, Compton-thick active galactic nuclei and suggests that we may need to revisit how we classify active galactic nuclei as Compton thick.

Kelly A. Douglass et al 2023 ApJS 265 7

Researchers have compiled new catalogs of cosmic voids — enormous regions of space that contain relatively few galaxies compared to extended filaments containing the bulk of the galaxies in our universe.
