Arbitrarily scaled copies of the NIFS spectrum

Arbitrarily scaled copies of the NIFS spectrum of the host galaxy of PG 1426+015 (black lines) with model fits (red lines) overlaid. The models of a M5 Ia supergiant (top spectrum) and a K5 III giant (bottom spectrum) have been broadened to match the width of the host-galaxy absorption features. The better fit with the supergiant spectrum is indicative of a young stellar population in the host galaxy.
