Carroll & ostlie an introduction to modern astrophysics for the monochromatic ux of cygnus a at different wavelengths: a) make a graph of log10(f) vs. and determine the value of the spectral index at log10() = 8 for the power law given in equation 1 (chapter 28, carroll & ostlie). b) use a simple trapezoid rule to investigate the area under the curve of f vs. for the data given, and use your answer to estimate the radio luminosity of cygnus a. hint: note, in part (b) you are integrating under the curve of f vs. not log10(f) vs. the distance to cygnus a is mpc (use h = 0.71).
