The redshift-space galaxy two-point correlation function and baryon acoustic oscillations
Donghui Jeong, Liang Dai, Marc Kamionkowski +1
Future galaxy surveys will measure baryon acoustic oscillations (BAOs) with high significance, and a complete understanding of the anisotropies of BAOs in redshift space will be im…
Spectral distortions from the dissipation of tensor perturbations
Jens Chluba, Liang Dai, Daniel Grin +2
Spectral distortions of the cosmic microwave background (CMB) may become a powerful probe of primordial perturbations at small scales. Existing studies of spectral distortions focu…
Tensor-induced B modes with no temperature fluctuations
Marc Kamionkowski, Liang Dai, Donghui Jeong
The recent indications for a tensor-to-scalar ratio from BICEP2 measurements of the cosmic microwave background (CMB) B-mode polarization present some tension with…
Linking the BICEP2 result and the hemispherical power asymmetry through spatial variation of
Jens Chluba, Liang Dai, Donghui Jeong +2
For the simplest inflation models, the recent detection of a large primordial B-mode polarization signal by the BICEP2 experiment indicates a slight tension with the upper limit on…
Reheating constraints to inflationary models
Liang Dai, Marc Kamionkowski, Junpu Wang
Evidence from the BICEP2 experiment for a significant gravitational-wave background has focussed attention on inflaton potentials with ("chaotic" or "$m^2ϕ…
New operator approach to the CMB aberration kernels in harmonic space
Liang Dai, Jens Chluba
Aberration kernels describe how harmonic-space multipole coefficients of cosmic microwave background (CMB) observables transform under Lorentz boosts of the reference frame. For sp…
