The APOGEE Library of Infrared SSP Templates (A-LIST): High-Resolution
  Simple Stellar Population Spectral Models in the H-Band
  Integrated light spectroscopy from galaxies can be used to study the stellar
populations that cannot be resolved into individual stars. This analysis relies
on stellar population synthesis (SPS) techniques to study the formation history
and structure of galaxies. However, the spectral templates available for SPS
are limited, especially in the near-infrared. We present A-LIST (APOGEE Library
of Infrared SSP Templates), a new set of high-resolution, near-IR SSP spectral
templates spanning a wide range of ages (2-12 Gyr), metallicities ($\rm -2.2 <
[M/H] < +0.4$) and $\alpha$ abundances ($\rm -0.2 < [\alpha/M] < +0.4$). This
set of SSP templates is the highest resolution ($R\sim22500$) available in the
near infrared, and the first such based on an empirical stellar library. Our
models are generated using spectra of $\sim$300,000 stars spread across the
Milky Way, with a wide range of metallicities and abundances, from the APOGEE
survey. We show that our model spectra provide accurate fits to M31 globular
cluster spectra taken with APOGEE, with best-fit metallicities agreeing with
those of previous estimates to within $\sim$0.1 dex. We also compare these
model spectra to lower-resolution E-MILES models and demonstrate that we
recover the ages of these models to within $\sim$1.5 Gyr. This library is
available in https://github.com/aishashok/ALIST-library.
