%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %%% ERRATA FOR DRAGAN HUTERER'S TEXTBOOK "A COURSE IN COSMOLOGY: FROM TEHORY TO PRACTICE %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% CHAPTER 2: - In Eq (2.18), the radial term should not be dr^2 / (1-kappa*r^2), but rather dr^2 / (1-k*r^2), where k = kappa/R0^2, and is dimensionful (while kappa = +/-1 or 0 is dimensionless). Then Eq. (2.20) will have factors of the radius of curvature R_0 multiplying the sin/sinh, and the latter's arguments will be divided by R_0, thus matching Eq (2.16), and (3.60). (thanks Jin Lee) - p.62 Etherington failure: could be loss of energy of photons (apart from redshift). p.189 (Box) Only scales larger than Jeans length grow. p.193-4,224 etc FT is sometimes written k.r, sometimes kr. (thanks Alan Heavens) CHAPTER 3: - below Eq (3.15) on p. 44, it should say "where n is the mean number density of gas particles" (not mass). (thanks Jin Lee) - the first two lines in Eq (3.40) should have a plus sign before the rho_K terms, not minus; this way they are consistent with Eq (3.8) and the rest of the definitions. (thanks Jin Lee) - the last term in Eq (3.53) should have 2+q_0, not 1+q_0. (thanks Jin Lee) - p44 - the last line reads "... P=n k_B T, where n is the mean mass of gas particles, ...". "mean mass" should read "number density". (thanks Jin Lee) CHAPTER 4: - in the second line of the last paragraph on p. 71 (just before Eq (4.1)), I define the density of states in phase space as d^6 N/(d^3 p d^3 x). It should read d^6 N_states/(d^3 p d^3 x) to be consistent with Eqn (4.1). N is reserved for the density of particles in phase space. (thanks Jin Lee) - In Fig 4.1 for the horizontal scale for time the last tick should read 10^2 instead of 10^-2; this typo has been introduced by the publisher. (thanks David Weinberg) CHAPTER 8: - Eqs (8.2) and (8.3) should have the curvature parameter k and not kappa, to match Eq (2.51) [since we don't have the curvature radius R_0 here]. (thanks Jin Lee) CHAPTER 9: - Eq 9.53: should have the additional 1/V term on the rhs. This is because , P(k), and the Dirac delta function all have units of volume or, equivalently, because of our Fourier-transform convention. (thanks Peter Espenshade) CHAPTER 10: - Fig 10.7 (MCMC): In the very last panel, weight should be 1, not 4 (the weight resets once the new model is accepted and one moves to it). CHAPTER 13: - Sec 13.3.3, when talking about the value of the sound horizon for our fiducial cosmology: rs should be about 100 (more precisely 98) h^{-1}Mpc, not 110. The previous calculation incorrectly ignored the relativistic-neutrino contribution to radiation content in H(z). [However I now get l_peak to be about 300, not 270, so even further than the true value of about 220.] - Fig 13.15: labels for fNL=\pm50000 and \pm 500 are swapped around (you can really only notice this in the color-plates version of the Figure) - Eqs 13.83: U instead of Q (thanks Benedetta Ried) APPENDIX B: - electron mass should of course be 511 keV, not 511 MeV. (thanks Jin Lee)
