Constraining neutrino mass and dark energy with peculiar velocities and lensing dispersions of Type Ia supernovae

Aniket Agrawal, Teppei Okumura, Toshifumi Futamase

We show that peculiar velocities of Type Ia supernovae can be used to derive constraints on the sum of neutrino masses, $\Sigma m_{\nu }$, and dark energy equation of state, $w = w_0+w_a(1-a)…
