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.

Dust reddening in Sloan Digital Sky Survey quasars [PDF]

, 2004
We explore the form of extragalactic reddening toward quasars using a sample of 9566 quasars with redshifts 0 0.1, and less than 1% have E(B-V) > 0.2, where the extinction is relative to quasars with modal colors.

Clusters, Clumps, Dust, and Gas (CCDG) in NGC 1614: Benchmarking Cluster Demographics in Extreme Systems

The Astronomical Journal
Observations of young star clusters in a variety of galaxies have been used to constrain basic properties related to star formation, such as the fraction of stars found in clusters (Γ) and the shape of the cluster mass function (CMF).

Reddening map of the Large Magellanic Cloud bar region [PDF]

, 2005
E(V-I) reddening values for 1123 locations in the bar region of the Large Magellanic Cloud are presented. V, I photometry of red clump stars identified in the Optical Gravitational Lensing Experiment II catalogue of LMC were used to estimate reddening. E(

Mapping the differential reddening in globular clusters [PDF]

, 2013
We build differential-reddening maps for 66 Galactic globular clusters (GCs) with archival Hubble Space Telescope WFC/ACS F606W and F814W photometry. Because of the different GC sizes (characterized by the half-light radius Rh) and distances to the Sun ...

THE PECULIAR EXTINCTION LAW OF SN 2014J MEASURED WITH THE HUBBLE SPACE TELESCOPE

, 2014
The wavelength dependence of the extinction of Type Ia SN 2014J in the nearby galaxy M82 has been measured using UV to near-IR photometry obtained with the Hubble Space Telescope, the Nordic Optical Telescope, and the Mount Abu Infrared Telescope.

Galactic reddening in 3D from stellar photometry - an improved map [PDF]

, 2018
We present a new 3D map of interstellar dust reddening, covering three quarters of the sky (declinations of δ ≳ -30°) out to a distance of several kiloparsecs. The map is based on high-quality stellar photometry of 800 million stars from Pan-STARRS 1 and

Evolution of dust attenuation in star-forming galaxies with UV slope, stellar mass, and redshift out to z∼5

Astronomy & Astrophysics
Context.To set reliable constraints on the dust-obscured portion of star formation across cosmic time, an accurate calibration of the so-called infrared excess (IRX ≡ LIR/LUV) and its dependence on intrinsic galaxy properties is required. While the local

Reddening-Free Indices in the VISTA Filter System

, 2014
Reddening-free indices represent a powerful, and yet little used, approach to problems where reddening/extinction constitute a serious issue, without having to deal with the extinction of any individual star.

Star Cluster Populations in 38 Spiral Galaxies: Evidence for Near-universal Mass and Age Distributions from PHANGS

The Astrophysical Journal
We present the largest study to date of star cluster mass and age distributions in nearby galaxies. The analysis is based on a uniformly selected catalog of over 15,000 (36,000) human- (machine-) classified compact clusters across 38 spiral galaxies in ...
