Jerry Edelstein,Kyoung-Wook Min,Wonyong Han,Eric J. Korpela,K. Nishikida,Barry Y. Welsh,Carl Heiles,J. Adolfo,Mark Bowen,WM Feuerstein,Ken McKee,Jeremy Lim,Kwangsun Ryu,Jong-Ho Shinn,Uk-Won Nam,Jang-Hyun Park,In-Soo Yuk,Ho Jin,Kwang-Il Seon,D. H. Lee,E. Sim +20 more
TL;DR: The Spectroscopy of Plasma Evolution from Astrophysical Radiation (SPEAR) data from the STSAT-1 satellite has been used to provide the first large-area spectral mapping of the cosmic far-ultraviolet (FUV; 900-1750 A) background.

TL;DR: The SPEAR (or "FIMS") instrumentation has been used to conduct the first large-scale spectral mapping of diffuse cosmic far-ultraviolet (FUV; 900-1750 A) emission, including important diagnostics of interstellar hot (104-106 K) and photoionized plasmas, H2, and dust-scattered starlight.
Journal ArticleDOI
Observation of the far-ultraviolet continuum background with spear/fims
Kwang-Il Seon,Kwang-Il Seon,Jerry Edelstein,Eric J. Korpela,Adolf N. Witt,Kyoung-Wook Min,Wonyong Han,Wonyong Han,Jong-Ho Shinn,Il-Joong Kim,Jae-Woo Park +10 more
TL;DR: In this paper, the authors present the general properties of the far-ultraviolet (FUV; 1370-1710 A) continuum background over most of the sky, obtained with the Spectroscopy of Plasma Evolution from Astrophysical Radiation (SPEAR) instrument (also known as FIMS), flown aboard the STSAT-1 satellite mission.
Journal ArticleDOI
Radiative transfer model of dust attenuation curves in clumpy, galactic environments
TL;DR: In this article, the authors investigated the attenuation of starlight by dust in galactic environments through models of radiative transfer in a spherical, clumpy ISM, and found that the model attenuation curves calculated with the MW dust are well represented by a modified Calzetti curve with a varying slope and UV bump strength.
Journal ArticleDOI
On the Origins of the Diffuse Hα Emission: Ionized Gas or Dust-scattered Hα Halos?
Kwang-Il Seon,Adolf N. Witt +1 more
TL;DR: In this paper, the authors re-examine the arguments against dust scattering and find that the dust-scattering origin of the diffuse H{alpha} emission cannot be ruled out.
