Redshift-Space Distortions in Lagrangian Perturbation Theory
Shi-Fan Chen, Zvonimir Vlah, Emanuele Castorina +1
We present the one-loop 2-point function of biased tracers in redshift space computed with Lagrangian perturbation theory, including a full resummation of both long-wavelength (inf…
Local Primordial Non-Gaussianities and Super-Sample Variance
Emanuele Castorina, Azadeh Moradinezhad Dizgah
Fluctuations with wavelengths larger than the volume of a galaxy survey affect the measurement of the galaxy power spectrum within the survey itself. In the presence of local Primo…
Packed Ultra-wideband Mapping Array (PUMA): Astro2020 RFI Response
Emanuele Castorina, Simon Foreman, Dionysios Karagiannis +13
The Packed Ultra-wideband Mapping Array (PUMA) is a proposed low-resolution transit interferometric radio telescope operating over the frequency range 200 - 1100MHz. Its rich scien…
Could quasar lensing time delays hint to a core component in halos, instead of H0 tension?
Kfir Blum, Emanuele Castorina, Marko Simonović
The time delay measured between the images of gravitationally lensed quasars probes a combination of the angular diameter distance to the source-lens system and the mass density pr…
