Scale and redshift dependent limits on cosmic neutrino properties

Understand

Cosmological neutrino mass and abundance measurements are reaching unprecedented precision.

• Testing their stability versus redshift and scale is a crucial issue, as it can serve as a guide for optimizing ongoing and future searches.
• Here, we perform such analyses, considering a number of redshift, scale, and redshift-and-scale nodes.
• Concerning the $k$-space analysis of $\sum m_\nu$, CMB observations are crucial, as they lead the neutrino mass constraints.
