SUMMARY:Are Bulges and Disks Real? *** Seminar cancelled *** - Michael Mer
 rifield (School of Physics and Astronomy\, University of Nottingham)

DESCRIPTION:Decomposing images of galaxies into separate bulge and disk co
 mponents has become a minor industry in studying galactic structure\, but 
 raises the question of whether such decompositions reflect an astrophysica
 l distinction\, or whether they have just become convenient fitting functi
 ons.  With the advent of large-scale spectroscopic data\, such as that off
 ered by the SDSS-IV MaNGA integral-field unit survey of 10\,000 nearby gal
 axies\, we can now address this question.  I will present the techniques t
 hat we have been developing to exploit these observations in novel ways\, 
 and the first results that are starting to emerge from this rich data set.
