4. What is an SED?: Dale et al. 2007 http://almaost.jb.man.ac.uk/ http://candels-collaboration.blogspot.com/2012/08/the-multi- wavelength-shapes-of-galaxies.html https://www.eso.org/public/images/eso0534a/

5. What does SED tell us? Age of stellar population Star formation rate Dust qualities AGN properties http://ned.ipac.caltech.edu/level5/March13/Lagache/Figures/figure1.jpghttp://ned.ipac.caltech.edu/level5/March05/Leitherer/Figures/figure6.jpg

Ultraviolet Optical Radio Infrared DATA GALEX Poor resolution Bands 1 and 2 Band 7: Cycle 0 3.2 mm Wavelength 2.2 arcsec = 155 Pc 349 GHz 8.55 mm Wavelength 93 GHz IRAC CTIO 1.5m telescope B,V,R,I 1.52 arcsec = 107 Pc ~ 4 arcsec ~ 2 arcsec ~ 2.4 arcsec 2.2 X 1.64 arcsec 1.52 X 1.21 arcsec Band 3: ALMA http://irsa.ipac.caltech.edu/data/SPITZER/S4G/galaxies/NGC1097.html http://irsa.ipac.caltech.edu/data/SPITZER/SINGS/ http://galex.stsci.edu/GR6/

7. Reduce DATA Regrid Convert Units Convolve How to create an SED: Cycle 0 ALMA Define ring? Jy / beam Use worst resolution Re-pixels images Outline Ring Subtract background 1.5 x radius of outer ring IRAC band 1 3.6 μm IRAC band 2 4.5 μm Galex FUV 1350-1780 Å Galex NUV 1770-2730 Å CTIO I.90 μm CTIO R.70 μm CTIO V.54 μm CTIO B.43 μm ALMA 7.85 mm.

8. Results:

9. SED’s are challenging! There is more work ahead Conclusions and Future work: Examine regions of interest within ring Fit an SED to circumnuclear ring Create error bars
