The infrared luminosity of retired and post-starburst galaxies: A cautionary tale for star formation rate measurements

Vivienne Wild, Natalia Vale Asari, Kate Rowlands +3

In galaxies with significant ongoing star formation there is an impressively tight correlation between total infrared luminosity (L${}_{TIR}$) and H$\alpha$ luminosity (L${}_{H\alpha }$), when H$…
