Title: A Spectroscopic Study of Infrared Sources near Sgr A East in the Galactic Center

Abstract: The Galactic center (GC) region is an extreme environment that comprises a small fraction of the galaxy but supports a relatively large star formation rate ($sim$0.1 $mathrm{M_{odot} yr^{-1}}$) compared to the rest of the galaxy ($sim$ 1.2 $mathrm{M_{odot} yr^{-1}}$). Studying star formation (SF) in the GC is very interesting because warm, turbulent environment is quite different from other locations in the galaxy. In this investigation, we plan to study a set of infrared sources which have been tentatively identified as young stellar objects (YSO). Our goal is to determine if they indeed YSOs with spectroscopic observations. To accomplish this goal, we are requesting observations with the ARCoIRIS spectrograph on the 4-m Blanco Telescope. Evidence of YSOs that have formed in the region will provide important insight into current SF activity in the GC, especially since these potential YSO candidates are isolated from any known cluster in the GC. If many of the objects in this study are confirmed as YSOs, this will provide strong evidence that isolated star formation is ongoing in the GC.
