Ly Halo Properties and Dust in the Circumgalactic Medium of z ∼ 2 Star-forming Galaxies

The Astrophysical Journal
We present Keck Cosmic Web Imager integral-field unit observations around extended Ly α halos of 27 typical star-forming galaxies with redshifts 2.0 < z < 3.2 drawn from the MOSFIRE Deep Evolution Field survey.

An Upper Limit of 106 M⊙ in Dust from ALMA Observations in 60 Little Red Dots

The Astrophysical Journal Letters
By virtue of their red color, the dust in little red dots (LRDs) has been thought to be of appreciable influence, whether that dust is distributed in a torus around a compact active galactic nucleus or diffuse in the interstellar medium of nascent ...

The Multiwavelength Extinction Law and Its Variation in the Coalsack Molecular Cloud Based on the Gaia, APASS, SMSS, 2MASS, GLIMPSE, and WISE Surveys

The Astrophysical Journal
Accurate interpretation of observations relies on the interstellar dust extinction law, which also serves as a powerful diagnostic for probing dust properties.

Extinction of Taurus, Orion, Perseus and California Molecular Clouds Based on the LAMOST, 2MASS, and Gaia Surveys. II. The Extinction Law

The Astronomical Journal
The extinction law from ultraviolet (UV) to infrared (IR; 0.2–24 μ m) is determined by relying on the blue-edge method and color-excess ratios for some nearby molecular clouds, from the low-mass star-forming region to the massive star-forming region. The

Interstellar Comet 3I/ATLAS: Evidence for Galactic Cosmic-Ray Processing

The Astrophysical Journal Letters
Spectral observations of 3I/ATLAS (C/2025 N1) with JWST/NIRSpec and SPHEREx reveal an extreme CO _2 enrichment (CO _2 /H _2 O = 7.6 ± 0.3) that is 4.5 σ above solar system comet trends and among the highest ever recorded.
