Ages of massive galaxies at $0.5<z<2.0$ from 3D-HST rest-frame optical spectroscopy

Mattia Fumagalli, Marijn Franx, Pieter van Dokkum +10

We present low-resolution near-infrared stacked spectra from the 3D-HST survey up to $z=2.0$ and fit them with commonly used stellar population synthesis models: BC03 (Bruzual & Ch…
