Description
We discuss the effects on the cosmic microwave background (CMB), cosmic
infrared background (CIB), and thermal Sunyaev-Zeldovich effect due to
the peculiar motion of an observer with respect to the CMB rest frame,
which induces boosting effects. After a brief review of the current
observational and theoretical status, we investigate the scientific
perspectives opened by future CMB space missions, focussing on the
Cosmic Origins Explorer (CORE) proposal. The improvements in sensitivity
offered by a mission like CORE, together with its high resolution over a
wide frequency range, will provide a more accurate estimate of the CMB
dipole. The extension of boosting effects to polarization and
cross-correlations will enable a more robust determination of purely
velocity-driven effects that are not degenerate with the intrinsic CMB
dipole, allowing us to achieve an overall signal-to-noise ratio of 13;
this improves on the Planck detection and essentially equals that of an
ideal cosmic-variance-limited experiment up to a multipole lsimeq2000.
Precise inter-frequency calibration will offer the opportunity to
constrain or even detect CMB spectral distortions, particularly from the
cosmological reionization epoch, because of the frequency dependence of
the dipole spectrum, without resorting to precise absolute calibration.
The expected improvement with respect to COBE-FIRAS in the recovery of
distortion parameters (which could in principle be a factor of several
hundred for an ideal experiment with the CORE configuration) ranges from
a factor of several up to about 50, depending on the quality of
foreground removal and relative calibration. Even in the case of simeq1
% accuracy in both foreground removal and relative calibration at an
angular scale of 1o, we find that dipole analyses for a
mission like CORE will be able to improve the recovery of the CIB
spectrum amplitude by a factor simeq 17 in comparison with current
results based on COBE-FIRAS. In addition to the scientific potential of
a mission like CORE for these analyses, synergies with other planned and
ongoing projects are also discussed.
