Direct comparison of sterile neutrino constraints from cosmological data, ${\nu }_e$ disappearance data and ${\nu }_{\mu }\to {\nu }_e$ appearance data in a $3+1$ model

We present a quantitative, direct comparison of constraints on sterile neutrinos derived from neutrino oscillation experiments and from Planck data, interpreted assuming standard c…
