The Epoch of Reionization (EoR) -- when ultraviolet photons emitted by the first stars and galaxies transformed the intergalactic medium from mostly neutral to mostly ionized -- is a primary science motivation of many current and upcoming facilities. The landscape of experiments is diverse, with some seeking a detection of the ionization field itself, and others instead going after the sources...
The epoch of cosmic reionization can be probed using the secondary anisotropies imprinted on the cosmic microwave background (CMB) temperature and polarization field. I will discuss the imprints of patchy reionization on the kSZ power spectrum and CMB B-mode polarization. I will introduce two new scaling relations to connect the kSZ and secondary B-mode power spectrum with the physics of...
Recent years have seen an explosion in the number of line intensity mapping experiments, particularly those targeting the Epoch of Reionization. By targeting unresolved emission of a variety of spectral lines, these surveys will provide new windows into the nature of the high-redshift objects responsible for ionizing the interstellar medium. In this talk, I will briefly summarize the status...
The kinematic Sunyaev-Zel’dovich (kSZ) effect contains a contribution from the inhomogeneous reionization process, and encodes valuable information about how reionization progressed. We examine several upcoming opportunities for cross-correlating the kSZ signal with other probes of Cosmic Dawn and the Epoch of Reionization. Specifically, we look at the 21cm signal, measured by radio...
In the era of the high-precision CMB measurements, in addition to the conventional power spectrum, other observables will help to constrain cosmology. For example, the gravitational lensing effect introduces correlations between different modes of CMB fluctuations. This mode-mode correlation has been used to reconstruct gravitational lensing from CMB data. Other secondary effects could also...
