Cross-tests of CMB features in the primordial spectra
  The recent Planck data on the power spectrum of temperature anisotropies of
the cosmic microwave background marginally support deviations from the
$\Lambda$CDM model at several multipoles. With a view towards current and
forthcoming observational surveys, we trace these features to other observables
like the scalar bispectrum and the tensor power spectrum. A possible detection
of such bumps in these channels would increase their statistical significance
shedding light on the ultra violet mechanisms responsible for their appearance
in the data.
