TL;DR: In this paper, a spectral energy distribution (SED) fitting procedure, capable of quickly and reliably recovering star formation history (SFH) and extinction parameters, is presented, where the SFH is modeled as discrete steps in time.

TL;DR: In this paper, the extinction curve derived from Infrared Space Observatory mid-infrared observations of the Galactic center exhibits a surprisingly flat behavior in the 3-8 μm region, contrary to the deep minimum expected from standard interstellar dust models consisting of bare silicate and graphite dust particles.

TL;DR: In this article, the extinction curve derived from ISO mid-infrared (IR) observations of the Galactic center (GC) exhibits a surprisingly flat behavior in the 3 to 8 micron region, contrary to the deep minimum expected from standard interstellar dust models consisting of bare silicate and graphite dust particles.

TL;DR: In this paper, the extragalactic nature of the NIRBL can be determined from the analysis of the TeV spectra of blazars, which can, in principle, offer a simple test for the nature and origin of the nIRBL.

TL;DR: Observations with the Hubble Space Telescope, conducted since 1990, now offer an unprecedented glimpse into fast astrophysical shocks in the young remnant of supernova 1987A, and it is found that the Lyα and Hα lines from shock emission continue to brighten, whereas their maximum velocities continue to decrease.
