Tracing the Cosmic Origins: Machine Learning Reconstruction of the Primordial Density Field from EoR Observations

Anchal Saxena, P. Daniel Meerburg, Guochao Sun +2

Reconstructing the initial conditions of the Universe from late-time tracers would unlock cosmological information buried by non-linear structure formation and astrophysics. We rec…

Simulation-Based Inference of the sky-averaged 21-cm signal from CD-EoR with REACH

Anchal Saxena, P. Daniel Meerburg, Christoph Weniger +2

The redshifted 21-cm signal from the Cosmic Dawn and Epoch of Reionization carries invaluable information about the cosmology and astrophysics of the early Universe. Analyzing data…

Constraining the X-ray heating and reionization using 21-cm power spectra with Marginal Neural Ratio Estimation

Anchal Saxena, Alex Cole, Simon Gazagnes +3

Cosmic Dawn (CD) and Epoch of Reionization (EoR) are epochs of the Universe which host invaluable information about the cosmology and astrophysics of X-ray heating and hydrogen rei…

Sky-averaged 21-cm signal extraction using multiple antennas with an SVD framework: the REACH case

Anchal Saxena, P. Daniel Meerburg, Eloy de Lera Acedo +2

In a sky-averaged 21-cm signal experiment, the uncertainty on the extracted signal depends mainly on the covariance between the foreground and 21-cm signal models. In this paper, w…

Impact of dark matter models on the EoR 21-cm signal bispectrum

Anchal Saxena, Suman Majumdar, Mohd Kamran +1

The nature of dark matter sets the timeline for the formation of first collapsed halos and thus affects the sources of reionization. Here, we consider two different models of dark…
