| 요약 | Gravitational lensing of the cosmic microwave background (CMB) has recently started to gain importance as a cosmological probe. With growing detection significance of this effect, it is necessary to further develop theoretical understanding of i |
| 요약 | We start by looking at correlations that the gravitational lensing induces between CMB temperature, polarization and reconstructed lensing potential and investigate how neglecting them in an analysis impacts constraints on cosmological parameter |
| 요약 | Then we discuss a method we developed to directly measure the gravitational lensing potential from the CMB data and explain how to practically perform such measurement. This method helps us understand why it is necessary to include the lensing-i |
| 요약 | In the final part of this work, we apply this methodology to check lensing consistency of the Planck satellite data. We find that it is not possible to resolve the lensing anomalies seen in this data even when allowing for an arbitrary gravitati |
