cds-question@unistra.frmagellanic-cloudssupernova-remnantsinfrared-astronomyspectroscopyspectral-energy-distributionWe present Spitzer, Wide-field Infrared Survey Explorer (WISE), and Herschel observations of the young supernova remnant (SNR) N132D in the Large Magellanic Cloud, including 3-40{mu}m Spitzer Infrared Spectrograph (IRS) mapping, 12{mu}m WISE and 70, 100, 160, 250, 350, and 500{mu}m Herschel images. The high-velocity lines of [NeII] at 12.8{mu}m, [NeIII] at 15.5{mu}m, and [OIV] 26{mu}m reveal infrared ejecta concentrated in a central ring and coincide with the optical and X-ray ejecta. Herschel images reveal far-IR emission coinciding with the central ejecta, which suggests that the IR emission is freshly formed, cold dust in the SN ejecta. The infrared spectra are remarkably similar to those of another young SNR of 1E0102 with Ne and O lines. Shock modeling of the Ne ejecta emission suggests a gas temperature of 300-600K and densities in the range 1000-2x10^4^cm^-3^ in the postshock photoionized region. The IR continuum from the ejecta shows an 18{mu}m peak dust feature. We performed spectral fitting to the IRS dust continuum and Herschel photometry. The dust mass associated with the central ejecta is 1.25+/-0.65M_{sun}_, while the 18{mu}m dust feature requires forsterite grains. The dust mass of the central ejecta region in N132D is higher than those of other young SNRs, which is likely associated with its higher progenitor mass. We discuss the dust productivity in the ejecta of N132D and infer its plausible implications for dust in the early universe.2023ApJ...949...74Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/949/74CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)VI/139 : Herschel Observation Log (Herschel Science Centre, 2013)J/A+A/420/763 : Electron impact excitation of NiII (Bautista+, 2004)J/A+A/475/765 : Fine structure forbidden lines in FeII (Ramsbottom+, 2007)J/ApJ/656/770 : Mid-IR spectrum of star-forming galaxies (Smith+, 2007)J/A+A/587/A93 : MeV-GeV counterparts of TeV sources (Rappoldi+, 2016)J/A+A/625/A122 : CIELO-RGS, soft X-ray ionized emission lines (Mao+, 2019)J/ApJ/905/55 : Bright-PAH galaxies from AKARI & Spitzer (ASESS) (Lai+, 2020)J/ApJS/257/36 : ISO supernovae remnants spectra (Millard+, 2021)J/other/Nat/601.201 : Photometry of SN 2019hgp (Gal-Yam+, 2022)J/ApJ/948/33 : HST proper motion measurements of SNR N132D (Banovetz+, 2023)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/949/74https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/949/74http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/949/74https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/949/74https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/949/74http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/949/74GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapInfrareddefaultJ/ApJ/949/74/table3Comparison of the line widths from different regionsrecnoRecord number assigned by the VizieR team.
