A Near-infrared Extinction and Reddening Map toward the Galactic Bulge Using UKIRT

The Astronomical Journal
The Galactic bulge is one of the most information-dense regions to study resolved stellar populations, variables, and transients, such as microlensing events.

Exploring the Wolf Approach to Constraining NIR Extinction Laws in the Corona Australis Molecular Cloud

The Astronomical Journal
The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

The Quasar-associated 2175 Å Dust Absorbers in the SDSS DR16 Quasar Catalog

The Astrophysical Journal Supplement Series
We present, for the first time, a systematic study of quasar-associated 2175 Å dust absorbers using spectroscopic data from the Sloan Digital Sky Survey Data Release 16 (DR16).

Interstellar extinction toward MWC 148

We analyse high resolution optical spectra of MWC148 (optical counterpart of the gamma-ray source HESS J0632+057) obtained at Observatoire de Haute Provence and Rozhen Observatory. We measure equivalent widths of 7 diffuse interstellar bands and estimate the interstellar extinction E_{B-V}=0.85 +/- 0.08.

Massive Acquisition of Ultraviolet Color Excess Information from GALEX and UVOT Bands

The Astrophysical Journal Supplement Series
This study employs stellar parameters from spectroscopic surveys and Zhang et al. (2023) based on Gaia BP/RP (XP) spectra, along with photometric data from Galaxy Evolution Explorer (GALEX), UV/Optical Telescope (UVOT), and Gaia, to obtain extensive ...

Silicate Extinction Profile Based on the Stellar Spectrum by Spitzer/IRS

The Astrophysical Journal
The 9.7 and 18 μ m interstellar spectral features, arising from the Si–O stretching and O–Si–O bending modes of amorphous silicate dust, are the strongest extinction features in the infrared.
