200-Micron continuum science Derek Ward-Thompson Jeremiah Horrocks Institute University of Central Lancashire Oxford ALMA Band 11 Meeting – 19-20 March 2013
Some science Core mass function and stellar IMF – exploring a causal relation (A&A 518, L102)
Resolution mismatch Merlin 0.1x0.05” (ALMA 0.15-3”) VLA 1x0.5” (Herschel 15-30”)
It’s a no-brainer! • ALMA Bands 1-10 don’t give temp. • Herschel et al too low resolution • No high-res 200-um alternative planned • Need temperature for column density • Need column density for mass • Need mass for astrophysics • We need ALMA Band 11…… • ……please build it !
