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…

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…
