Scientific paper

We present Herschel observations of SMM J1633554.2+661225, which is a galaxy at z = 2.515 that is gravitationally lensed by the galaxy cluster Abell 2218, with a magnification of 22. Using the Herschel SPIRE 250, 350, & 500 micron observations, which span the peak of dust emission at this redshift, we derive a more robust infrared luminosity and measure the dust temperature for the first time. These new Herschel results are compared to the Spitzer results of this galaxy, specifically the Herschel derived star formation rate (SFR) is compared with the previous Spitzer SFR, based on Paschen-alpha emission.
