The Optical - Infrared Colors of CORALS QSOs: Searching for Dust Reddening Associated With High Redshift Damped Lyman Alpha Systems

open access: yes, 2005
The presence of dust in quasar absorbers, such as damped Lyman alpha (DLA) systems, may cause the background QSO to appear reddened. We investigate the extent of this potential reddening by comparing the optical-to-infrared (IR) colors of QSOs with and ...

Experiences and Expectations of LGBTQ+ Students Before Entering College

open access: yesNew Directions for Higher Education, Volume 2025, Issue 210, Page 11-18, Summer 2025.
ABSTRACT A variety of pre‐college experiences shape students’ expectations for college. These experiences, and corresponding expectations, provide valuable insights for postsecondary programming and support serving first‐year students. This article begins with an overview of literature on the experiences of LGBTQ+ students in K‐12 settings, including ...

The Multiwavelength Extinction Law and Its Variation in the Coalsack Molecular Cloud Based on the Gaia, APASS, SMSS, 2MASS, GLIMPSE, and WISE Surveys

open access: yesThe Astrophysical Journal
Accurate interpretation of observations relies on the interstellar dust extinction law, which also serves as a powerful diagnostic for probing dust properties.

Extensive HST Ultraviolet Spectra and Multi-wavelength Observations of SN 2014J in M82 Indicate Reddening and Circumstellar Scattering by Typical Dust

open access: yes, 2014
SN 2014J in M82 is the closest detected Type Ia supernova (SN Ia) in at least 28 years and perhaps in 410 years. Despite its small distance of 3.3 Mpc, SN 2014J is surprisingly faint, peaking at V = 10.6 mag, and assuming a typical SN Ia luminosity, we ...

Physical analysis and inverse methods applied to archaeological FIRE replications on ATACAMA desert soils, northern Chile

open access: yesArchaeometry, Volume 67, Issue 3, Page 625-641, June 2025.
Abstract Physical analysis of in situ fire experiments on soils are useful for the estimation of subsurface thermal diffusivity, which is affected by factors such as water, heterogeneity and heating conditions. To address the uncertainties due to these factors, a new data‐processing procedure based on inverse methods was developed and experimentally ...

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

open access: yesThe 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).

Deep optical survey of the stellar content of Sh2-311 region

open access: yes, 2014
The stellar content in and around Sh2-311 region have been studied using the deep optical observations as well as near-infrared (NIR) data from 2MASS. The region contains three clusters, viz. NGC 2467, Haffner 18 and Haffner 19.

Lactea: Web‐Based Spectrum‐Preserving Multi‐Resolution Visualization of the GAIA Star Catalog

open access: yesComputer Graphics Forum, Volume 44, Issue 3, June 2025.
Abstract The explosion of data in astronomy has resulted in an era of unprecedented opportunities for discovery. The GAIA mission's catalog, containing a large number of light sources (mostly stars) with several parameters such as sky position and proper motion, is playing a significant role in advancing astronomy research and has been crucial in ...

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

open access: yesThe 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.
