A new constraint on the -distortion with FIRAS: implications for feedback models in galaxy formation and cosmic shear measurements
Giulio Fabbian, Federico Bianchini, Alina Sabyr +4
The -type distortion of the blackbody spectrum of the cosmic microwave background radiation probes the pressure of the gas trapped in galaxy groups and clusters. We reanalyze ar…
SPECTER: An Instrument Concept for CMB Spectral Distortion Measurements with Enhanced Sensitivity
Alina Sabyr, Carlos Sierra, J. Colin Hill +1
Deviations of the cosmic microwave background (CMB) energy spectrum from a perfect blackbody uniquely probe a wide range of physics, ranging from fundamental physics in the primord…
A new constraint on the -distortion with FIRAS: robustness of component separation methods
Alina Sabyr, Giulio Fabbian, J. Colin Hill +1
The sky-averaged Compton- distortion in the cosmic microwave background (CMB) energy spectrum, , provides information about energy injection in the Universe o…
CLASS_SZ II: Notes and Examples of Fast and Accurate Calculations of Halo Model, Large Scale Structure and Cosmic Microwave Background Observables
Boris Bolliet, Aleksandra Kusiak, Fiona McCarthy +16
These notes are very much work-in-progress and simply intended to showcase, in various degrees of details (and rigour), some of the cosmology calculations that class_sz can do. We…
Constraining cosmology with thermal Sunyaev-Zel'dovich maps: Minkowski functionals, peaks, minima, and moments
Alina Sabyr, J. Colin Hill, Zoltan Haiman
The thermal Sunyaev-Zel'dovich effect (tSZ) is a sensitive probe of cosmology, as it traces the abundance of galaxy clusters and groups in the late-time Universe. Upcoming cosmic m…
The Primordial Inflation Explorer (PIXIE): Mission Design and Science Goals
Alan Kogut, Eric Switzer, Dale Fixsen +14
The Primordial Inflation Explorer (PIXIE) is an Explorer-class mission concept to measure the energy spectrum and linear polarization of the cosmic microwave background (CMB). A si…
