Cosmology and Source Redshift Distributions from Combining Radio Weak Lensing with CMB Lensing

Alba Kalaja, Ian Harrison, William R Coulton

Measurements of weak gravitational lensing using the cosmic microwave background and the shapes of galaxies have refined our understanding of the late-time history of the Universe.…

The reconstructed CMB lensing bispectrum

Alba Kalaja, Giorgio Orlando, Aleksandr Bowkis +3

Weak gravitational lensing by the intervening large-scale structure (LSS) of the Universe is the leading non-linear effect on the anisotropies of the cosmic microwave background (C…

The Simons Observatory: Constraining inflationary gravitational waves with multi-tracer B-mode delensing

Toshiya Namikawa, Anton Baleato Lizancos, Naomi Robertson +32

We introduce and validate a delensing framework for the Simons Observatory (SO), which will be used to improve constraints on inflationary gravitational waves (IGWs) by reducing th…

Fundamental limits on constraining primordial non-Gaussianity

Alba Kalaja, P. Daniel Meerburg, Guilherme L. Pimentel +1

We study the cosmic variance limit on constraining primordial non-Gaussianity for a variety of theory-motivated shapes. We consider general arguments for 2D and 3D surveys, with a…

From Primordial Black Holes Abundance to Primordial Curvature Power Spectrum (and back)

Alba Kalaja, Nicola Bellomo, Nicola Bartolo +5

In the model where Primordial Black Holes (PBHs) form from large primordial curvature (C) perturbations, i.e., CPBHs, constraints on PBH abundance provide in principle constraints…
