Measuring our velocity from fluctuations in number counts
Nidhi Pant, Aditya Rotti, Carlos A. P. Bengaly +1
Our velocity relative to the cosmic microwave background (CMB) generates a dipole from the CMB monopole, which was accurately measured by COBE. The relative velocity also modulates…
Estimating SI violation in CMB due to non-circular beam and complex scan in minutes
Nidhi Pant, Santanu Das, Aditya Rotti +2
Mild, unavoidable deviations from circular-symmetry of instrumental beams along with scan strategy can give rise to measurable Statistical Isotropy (SI) violation in Cosmic Microwa…
Recovering hidden signals of statistical anisotropy from a masked or partial CMB sky
Pavan K. Aluri, Nidhi Pant, Aditya Rotti +1
Any isotropy violating phenomena on cosmic microwave background (CMB) induces off-diagonal correlations in the two-point function. These correlations themselves can be used to esti…
Planck 2015 results. XII. Full Focal Plane simulations
Planck Collaboration, P. A. R. Ade, N. Aghanim +228
We present the 8th Full Focal Plane simulation set (FFP8), deployed in support of the Planck 2015 results. FFP8 consists of 10 fiducial mission realizations reduced to 18144 maps,…
Planck 2015 results. XVI. Isotropy and statistics of the CMB
Planck Collaboration, P. A. R. Ade, N. Aghanim +242
We test the statistical isotropy and Gaussianity of the cosmic microwave background (CMB) anisotropies using observations made by the Planck satellite. Our results are based mainly…
A novel approach to reconstructing signals of isotropy violation from a masked CMB sky
Pavan K. Aluri, Nidhi Pant, Aditya Rotti +1
Statistical isotropy (SI) is one of the fundamental assumptions made in cosmological model building. This assumption is now being rigorously tested using the almost full sky measur…
