A new reddening law for M4

, 2011
We have used broad-band near infrared photometry in combination with optical Johnson-Cousins photometry to study the dust properties in the line of sight to the Galactic globular cluster M4.

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

, 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

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.

GALACTIC EXTINCTION AND REDDENING FROM THE SOUTH GALACTIC CAP u -BAND SKY SURVEY: u -BAND GALAXY NUMBER COUNTS AND u − r COLOR DISTRIBUTION

, 2017
We study the integral Galactic extinction and reddening based on the galaxy catalog of the South Galactic Cap u-band Sky Survey (SCUSS), where u-band galaxy number counts and u - r color distribution are used to derive the Galactic extinction and ...

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 and Extinction Toward the Galactic Bulge from OGLE-III: The Inner Milky Way’s RV ∼ 2.5 Extinction Curve1

, 2016
We combine V I photometry from OGLE-III with V V V and 2MASS mea-surements of E(J −Ks) to resolve the longstanding problem of the non-standard optical extinction toward the Galactic bulge.

Effective Temperatures of BA-Type Supergiants from SED Fitting

Galaxies
Supergiants are luminous post-main-sequence massive stars whose effective temperatures (Teff) are key inputs for stellar evolution and feedback studies.

Dynamical and Photometric Analysis of NGC 146 and King 14: Evidence for a Comoving, Unbound Cluster Pair

The Astronomical Journal
To understand the nature of the NGC 146–King 14 cluster pair, we conducted a detailed photometric, astrometric, and dynamical study using multiwavelength data from Gaia DR3, Pan-STARRS1, WISE, and TESS.
