Dark matter component decaying after recombination: Sensitivity to BAO and RSD probes
A. Chudaykin, D. Gorbunov, I. Tkachev
It has been recently suggested~\cite{Berezhiani:2015yta} that a subdominant fraction of dark matter decaying after recombination may alleviate tension between high-redshift (CMB an…
Dark matter component decaying after recombination: lensing constraints with Planck data
A. Chudaykin, D. Gorbunov, I. Tkachev
It has been recently suggested~\cite{Berezhiani:2015yta} that emerging tension between cosmological parameter values derived in high-redshift (CMB anisotropy) and low-redshift (clu…
Reconciling Planck results with low redshift astronomical measurements
Z. Berezhiani, A. D. Dolgov, I. I. Tkachev
We show that emerging tension between the direct astronomical measurements at low redshifts and cosmological parameters deduced from the Planck measurements of the CMB anisotropies…
Constraints on millicharged particles from Planck
A. D. Dolgov, S. L. Dubovsky, G. I. Rubtsov +1
We revisit cosmic microwave background (CMB) constraints on the abundance of millicharged particles based on the Planck data. The stringent limit Omega_{mcp}h^2 < 0.001 (95% CL) ma…
