Problem 1

Construct the differential equation for the photons' distribution function $\varphi(\omega,t)$ in a homogeneous and isotropic Universe.


Problem 1

The magnitude of dipole component of anisotropy generated by the Solar system's motion relative to the relic radiation equals $\Delta T_d\simeq3.35mK$. Determine the velocity of the Solar system relative to the relic radiation.


Problem 1

Estimate the magnitude of annual variations of CMB anisotropy produced by rotation of the Earth around the Sun.


Problem 1

Show that the angular resolution $\Delta\theta$ is related to the maximum harmonic $l_{max}$ (in the spherical harmonics decomposition) by \(\Delta\theta={180^\circ}/{l_{max}}.\)


Problem 1

Does the measurement of velocity relative to the CMB mean violation of the relativity principle and an attempt to introduce an absolute reference frame?
