Abstract

We describe an instrument concept and basic feasibility study for a new observational technique which we call Stabilized-sPeckle Integral Field Spectroscopy (SPIFS). SPIFS will enable, under certain observational conditions and constraints, low-to-modest-Strehl diffraction-limited imaging spectroscopy from large ground-based telescopes in the optical bandpass (i.e. V, R, and I bands). SPIFS is capable of exploring important scientific niches which are not currently available using existing high angular resolution techniques such as adaptive optics or speckle imaging, using existing, relatively-inexpensive technology. Based on our simulations presented in a companion paper (Keremedjiev, Eikenberry & Carson, 2008), SPIFS can provide integral field spectroscopy at ~15-mas resolution and ~3% Strehl over the I-band with sky coverage of ~20% to 100% in the Galactic Plane and ~5% at the Galactic poles. We present an overview of the SPIFS technique and simulated performance in realistic observations of the microquasar SS 433 to demonstrate one simple example of the power of SPIFS.
