An Ultraviolet Study of Star-Forming Regions in M31

, 2009
We present a comprehensive study of star-forming (SF) regions in the nearest large spiral galaxy M31. We use GALEX far-UV (1344-1786 \AA, FUV) and near-UV (1771-2831 \AA, NUV) imaging to detect young massive stars and trace the recent star formation ...

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 ...

Nanodust in the Interstellar Medium in Comparison to the Solar System

, 2012
Nanodust, which undergoes stochastic heating by single starlight photons in the interstellar medium, ranges from angstrom-sized large molecules containing tens to thousands of atoms (e.g.

Reddening law and interstellar dust properties along Magellanic sight-lines

, 2007
This study establishes that SMC, LMC and Milky Way extinction curves obey the same extinction law which depends on the 2200A bump size and one parameter, and generalizes the Cardelli, Clayton and Mathis (1989) relationship.

On the Variation of Interstellar Dust Extinction

Dust obscures astronomical observations and plays a important role in the evolution of galaxies. Mapping dust in three dimensions not only allows accurate correction of observations but also constrains the evolution of the interstellar medium (ISM). Extinction is the central observable to trace the density and properties of dust, and is widely employed

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.

Time Evolution of Optical Darkness in Gamma-Ray Burst Afterglow: The Case of GRB 240825A

The Astrophysical Journal
Long-duration gamma-ray bursts (GRBs) are believed to occur in star-forming regions. The multiwavelength follow-up observations of the early afterglow of GRB 240825A provided insights into the evolution of the optical-to-X-ray spectral feature of the ...
