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. 32, Eq (2.49): the critical density in the last line should be 1.053e10
h^2 eV/m^3, not 1.053e10 eV^4.
- 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:
- p. 193, 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)
- p. 203, just below Eq (9.67), it should say "direction-independent" and not
"redshift-independent" [since \spar and \sperp are of course redshift-dependent].
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:
- p. 402: units of G should be m^3/kg/s^2, not m^3/kg/m^2 (thanks Jin Lee)
- p. 402: electron mass should of course be 511 keV, not 511 MeV. (thanks Jin Lee)
