The 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 ...

The Luminosity & Mass Function of the Trapezium Cluster: From B stars to the Deuterium Burning Limit [PDF]

, 2002
We use the results of a new, multi-epoch, multi-wavelength, near-infrared census of the Trapezium Cluster in Orion to construct and to analyze the structure of its infrared (K band) luminosity function.

Detective Work and Invisible Assessments: Unpacking Discretionary Processes in Welfare Decision‐Making

Social Policy &Administration, EarlyView.
ABSTRACT Frontline discretion serves as a core function in welfare delivery. However, little is known about the process between input and output of discretionary assessments. As welfare administrations increasingly explore automated decision‐support systems to improve consistency and efficiency, it becomes crucial to understand the mechanisms and ...

Dust accretion and destruction in galaxy groups and clusters [PDF]

, 2010
We examine the dust distribution around a sample of 70,000 low redshift galaxy groups and clusters derived from the Sloan Digital Sky Survey. By correlating spectroscopically identified background quasars with the galaxy groups we obtain the relative ...

Thermal Segregation and Reddening in Europa's Double Ridges

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...

The Effect of a Nonuniversal Extinction Curve on the Wesenheit Function and Cepheid Distances

The Astrophysical Journal Letters
The Wesenheit function is widely used to reduce the effects of interstellar reddening in distance measurements. Its construction, however, relies on the assumption of a universal extinction curve and on fixed values of the total-to-selective extinction ...

Near-infrared reddening of extra-galactic GMCs in a face-on geometry

, 2008
[Abridged] We describe the near-infrared reddening signature of giant molecular clouds (GMCs) in external galaxies. In particular, we examine the E(J-H) and E(H-K) color-excesses, and the effective extinction law observed in discrete GMC regions. We also

Establishing Biodigestate Based Fertilizer's Value Within the Agricultural Community: A Key Prerequisite of Bioenergy Commercial Viability

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This research investigated the barriers and opportunities for biodigestate, a key by product of bioenergy production, as an input to commercial agricultural operations within New Zealand. The qualitative research examined in detail how the product fitted into the agricultural community.

The Absolute Magnitudes of Type Ia Supernovae in the Ultraviolet [PDF]

, 2010
We examine the absolute magnitudes and light-curve shapes of 14 nearby(redshift z = 0.004--0.027) Type Ia supernovae (SNe~Ia) observed in the ultraviolet (UV) with the Swift Ultraviolet/Optical Telescope.
