R associations. VI - The reddening law in dust clouds and the nature of early-type emission stars in nebulosity from a study of five associations

The Astronomical Journal, 1982
Positions, identification charts, UBVRIKLMN photometry and spectral types are given for stars, illuminating reflection nebulae that are visible on the POSS prints, which have been identified in five associations. With a ratio of total to selective extinction of 4.2, the reddening law applicable to the dust clouds in which the stars are embedded is ...

Question the Mark: A Review and Assessment of Bat Marking Practices

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

PhotoD with LSST: Stellar Photometric Distances Out to the Edge of the Galaxy

The Astronomical Journal
As demonstrated with the Sloan Digital Sky Survey (SDSS), Pan-STARRS, and most recently with Gaia data, broadband near-UV to near-IR stellar photometry can be used to estimate distance, metallicity, and interstellar dust extinction along the line of ...

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...

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.

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).

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

Untangling dust emission and cosmic infrared background anisotropies with the scattering transform statistics

Astronomy & Astrophysics
Context. A template-fit approach is often used to separate the Galactic dust emission and the cosmic infrared background (CIB) anisotropies in low H I column density regions using the observational fact that the 21 cm H I line emission from neutral ...

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.
