Constraints on primordial non-Gaussianity from Quaia
Giulio Fabbian, David Alonso, Kate Storey-Fisher +1
We analyse the large-scale angular clustering of quasars in the \gaia-\unwise quasar catalog, \quaia, and their cross-correlation with maps of the lensing convergence of the Cosmic…

Thomas Cornish, David Alonso, Boris Leistedt +1
Recent work has developed a formalism for computing angular power spectra directly from catalogues containing field values at discrete positions on the sky, thereby circumventing t…
