The Mid-Infrared Luminosities of Normal Galaxies Over Cosmic Time

Abstract: Modern population synthesis models estimate that 50% of the restframe K-band light is produced by TP-AGB stars during the first Gyr of a stellar population, with a substantial fraction continuing to be produced by the TP-AGB over a Hubble time. Between 0.2 and 1.5 Gyr, intermediate mass stars evolve into TP-AGB C stars which, due to significant amounts of circumstellar dust, emit half their energy in the mid-IR. We combine these results using published mid-IR colors of Galactic TP-AGB M and C stars to construc… Show more

This effect becomes increasingly important with decreasing SFR (Calzetti et al 2010;Smith et al 2012;Rowlands et al 2014;Utomo et al 2014).…”

“…This effect becomes increasingly important with decreasing SFR (Calzetti et al 2010;Smith et al 2012;Rowlands et al 2014;Utomo et al 2014). When the contribution of older stellar populations to dust heating is non-negligible, the implicit averaging timescale is >> 100 Myr (Salim et al 2009;Kelson & Holden 2010). Emission from active galactic nuclei (AGN) can also heat dust and thus cause the IR-inferred SFR to overestimate the true SFR.…”

“…2 shows the resulting 8 µm-non stellar image. Similarly, the 24 µm flux is also contaminated by emission from old stellar populations and hot, circumstellar dust (e.g., Salim et al 2009;Kelson & Holden 2010;Martini, Dicken & Storchi-Bergmann 2013). To remove this emission, we apply the same scaling method used for the 8 µm.…”

“…Poggianti & Wu 2000), where dust is heated by young stars in obscured super star clusters (responsible for the ultraviolet flux) and in the circumstellar envelopes of AGB stars (e.g. Kelson & Holden 2010;Chisari & Kelson 2012).…”
