cds-question@unistra.frgalaxiesinfrared-sourcesredshiftedastronomical-reference-materialsspectral-energy-distributionMassive Population II galaxies undergoing the first phase of vigorous star formation after the initial Population III stage should have high energy densities and silicate-rich interstellar dust. We have modeled the resulting far-infrared spectral energy distributions (SEDs), demonstrating that they are shifted substantially to bluer ("warmer") wavelengths relative to the best fitting ones at z~3, and with strong outputs in the 10-40{mu}m range. When combined with a low level of emission by carbon dust, their SEDs match that of Haro 11, a local moderately low-metallicity galaxy undergoing a very young and vigorous starburst that is likely to approximate the relevant conditions in young Population II galaxies. We expect to see similar SEDs at high redshifts (z>~5) given the youth of galaxies at this epoch. In fact, we find a progression with redshift in observed galaxy SEDs, from those resembling local ones at 2<~z<4 to a closer resemblance with Haro 11 at 5<~z<7. In addition to the insight on conditions in high-redshift galaxies, this result implies that estimates of the total infrared luminosities at z~6 based on measurements near {lambda}~1mm can vary by factors of 2-4, depending on the SED template used. Currently popular modified blackbodies or local templates can result in significant underestimates compared with the preferred template based on the SED of Haro 11.2018ApJ...869....4Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/869/4CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/95/1 : Atlas of Quasar Energy Distributions (Elvis+ 1994)J/ApJ/684/136 : SEDs of ELAIS-S1 mid-IR sources (Gruppioni+, 2008)J/ApJ/692/556 : Star forming galaxy templates (Rieke+, 2009)J/ApJ/738/69 : SEDs of galaxies at 3.8<z<5 in GOODS (Shim+, 2011)J/A+A/533/A119 : GOODS-Herschel North and South catalogs (Elbaz+, 2011)J/A+A/527/A109 : Dust and PAH emission SEDs of disk galaxies (Popescu+, 2011)J/A+A/551/A100 : Panchromatic SED of Herschel sources (Berta+, 2013)J/A+A/557/A66 : Effective SEDs of IR gal. at various z (Bethermin+, 2013)J/A+A/565/A128 : Dust SED in HRS nearby galaxies (Ciesla+, 2014)J/A+A/582/A121 : Dust properties in galaxies (Remy-Ruyer+, 2015)J/ApJS/219/18 : LIRAS: LoCuSS IR AGN survey (Xu+, 2015)J/MNRAS/462/1989 : HerMES Large Mode Survey catalogue (Asboth+, 2016)J/ApJ/822/109 : MIR view of polar dust emission in local AGNs (Asmus+, 2016)J/ApJS/229/25 : GOALS sample PACS and SPIRE fluxes (Chu+, 2017)J/ApJ/841/76 : Intrinsic far-IR SED of luminous AGNs (Lyu+, 2017)J/A+A/609/A130 : [CII] luminosities of gal. in G.A.S.+Cloudy (Lagache+, 2018)J/A+A/609/A30 : Conversion factors to LIR & Mdust (Schreiber+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/869/4https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/869/4http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/869/4https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/869/4https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/869/4http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/869/4GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/869/4/table1 (Galaxies with FIR SED measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/869/4/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/869/4/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/869/4/table1?GETtext/xml+votable180.050000true189.087416762.28605560.0055555555555555566/2710 4096 4507 6077 6552 7242 10152 10154 10155 10156 10209 10266 10336 10438 10448 11249 11252 11626 16438 16439 18055 18060 19089 21852 23191 26053 26280 27256 27258 27307 28614 33762 33836 33893 33944 34026 34033 34058 34312 34343 35053 35336 35396 35570 35935 45850 45891 45907 46108 46149 46151 46171 46178 46184 46203 46340 46342 46352 46603https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/869/4?format=asciiInfrareddefaultJ/ApJ/869/4/table1Galaxies with FIR SED measurementsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
