3) (5 points) Using the figure above, for the same galaxy:
a) (2.5 points) calculate the V-band Luminosity of the galaxy (in Lo) and the average
surface brightness of the galaxy (in Lo pc-2) interior to Re. You may assume
that Re in V-band is the same as that in R-band
b) (1.5 points) calculate the total mass of this galaxy (in Mo). Since the PE of a Sérsic
function is non-trivial, you may assume that the total mass can be calculated using a
uniform density sphere with a radius of Re.
c) (1 points) calculate the V-band apparent magnitude of this galaxy.
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction
of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice.
