Modeling beam chromaticity for high-resolution CMB analyses

Autor: Giardiello, S., Duivenvoorden, A. J., Calabrese, E., Galloni, G., Hasselfield, M., Hill, J. C., La Posta, A., Louis, T., Madhavacheril, M., Pagano, L.

We investigate the impact of beam chromaticity, i.e., the frequency dependence of the beam window function, on cosmological and astrophysical parameter constraints from CMB power spectrum observations. We show that for future high-resolution CMB meas

Two shadows on two backlights: forecasting the Ly-$\alpha$ forest $\times$ CMB Lensing bispectrum from ACT/SO/S4 & DESI

Autor: La Posta, Adrien, Schaan, Emmanuel

We forecast the sensitivity of future correlations between CMB lensing and the Lyman-$\alpha$ forest power spectrum. This squeezed-limit bispectrum probes the connection between the Lyman-$\alpha$ transmission and the underlying large-scale matter de

High-fidelity simulations of microramp-controlled shock wave/boundary layer interaction

Autor: Della Posta, Giacomo, Martelli, Emanuele, Salvadore, Francesco, Bernardini, Matteo

Microvortex generators (MVGs) are a promising solution to control shock wave/turbulent boundary layer interactions (SBLIs). This study examines the effects of a microramp VG on an SBLI generated by an oblique shock wave and a turbulent boundary layer

Spatial variations in the cosmic electron density after reionization generate cosmic microwave background anisotropies via Thomson scattering, a process known as the ``patchy screening" effect. In this paper, we propose a new estimator for the patchy

Observations of the millimeter sky contain valuable information on a number of signals, including the blackbody cosmic microwave background (CMB), Galactic emissions, and the Compton-$y$ distortion due to the thermal Sunyaev-Zel'dovich (tSZ) effect.
