A Detailed Analysis of Intermediate-scale Structure in Optical Extinction Curves: Expanded Census and Two-family Classification
C. M. Gunasekera, M. Decleir, K. D. Gordon +4
The features of interstellar extinction curves serve as powerful diagnostics for interstellar dust, revealing information about its composition, size distribution, and the physical…
JWST Spectra Indicate a Large Mass of Postshock Dust Formed by SN 2010jl
Nathan Smith, Melissa Shahbandeh, Ori D. Fox +22
The paper reports JWST mid‑infrared spectra of the Type IIn supernova SN 2010jl 13 years after explosion, revealing a large (~0.2 M☉) mass of warm dust formed in the post‑shock reg…
Large Variations Seen in First Ultraviolet Spectroscopic M33 Dust Extinction Curves
Karl D. Gordon, Petia Yanchulova Merica-Jones, Geoffrey C. Clayton +4
Dust extinction curves provide one of the main avenues to understanding the detailed nature of dust grains and accounting for the effects of dust on observations of many astrophysi…
Nature or Nurture: LMC-like Dust in the Solar Metallicity Galaxy M31
Geoffrey C. Clayton, Petia Yanchulova Merica-Jones, Karl D. Gordon +6
Using the {\it Hubble Space Telescope}/Space Telescope Imaging Spectrograph, ultraviolet (UV) extinction curves have been measured in M31 along thirteen new sightlines, increasing…
Expanded Sample of Small Magellanic Cloud Ultraviolet Dust Extinction Curves: Correlations between the 2175 A bump, q_pah, UV extinction shape, and N(HI)/A(V)
Karl D. Gordon, E. L. Fitzpatrick, Derck Massa +7
The Small Magellanic Cloud (SMC) shows a large variation in ultraviolet (UV) dust extinction curves, ranging from Milky Way-like (MW) to significantly steeper curves with no detect…
