Tensor Microwave Background Fluctuations for Large Multipole Order
Raphael Flauger, Steven Weinberg
We present approximate formulas for the tensor BB, EE, TT, and TE multipole coefficients for large multipole order l. The error in using the approximate formula for the BB multipol…
A No-Truncation Approach to Cosmic Microwave Background Anisotropies
Steven Weinberg
We offer a method of calculating the source term in the line-of-sight integral for cosmic microwave background anisotropies without using a truncated partial-wave expansion in the…
Must Cosmological Perturbations Remain Non-Adiabatic After Multi-Field Inflation?
Steven Weinberg
Even if non-adiabatic perturbations are generated in multi-field inflation, the perturbations will become adiabatic if the universe after inflation enters an era of local thermal e…
Can Non-Adiabatic Perturbations Arise After Single-Field Inflation?
Steven Weinberg
It is shown that non-adiabatic cosmological perturbations cannot arise during the period of reheating following inflation with a single scalar inflaton field.
Damping of Tensor Modes in Cosmology
Steven Weinberg
An analytic formula is given for the traceless transverse part of the anisotropic stress tensor due to free streaming neutrinos, and used to derive an integro-differential equation…
Adiabatic Modes in Cosmology
Steven Weinberg
We show that the field equations for cosmological perturbations in Newtonian gauge always have an adiabatic solution, for which a quantity is non-zero and constant in al…
