A photometric map of interstellar reddening within 300 parsecs

The Astrophysical Journal Supplement Series, 1982
An observational program is described which has as its goal a high resolution, three-dimensional survey of the dust component of the interstellar medium in the solar neighborhood. A network of approx.3450 bright A and F stars was established in the northern hemisphere with the intent that the stars act as probes for the detection of interstellar ...

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

UBVJHKLM Photometry and Low-Resolution Spectroscopy of Nova Delphini 2013 (V339 Del)

Open Astronomy, 2015
We present UBVJHKLM photometric observations of Nova Delphini 2013 that started several hours before maximum light and lasted for 130 nights. Using the obtained data, we derived several photometric parameters of the Nova: the time of maximum light ...

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.
