Abstract

The Thermal Infrared imager for the GMT which provides Extreme contrast and Resolution (TIGER) is intended as a small-scale, targeted instrument capable of detecting and characterizing exoplanets and circumstellar disks, around both young systems in formation, and more mature systems in the solar neighborhood. TIGER can also provide general purpose infrared imaging at wavelengths from 1.5-14 μm. The instrument will utilize the facility adaptive optics (AO) system. With its operation at NIR to MIR wavelengths (where good image quality is easier to achieve), and much of the high-impact science using modestly bright guide stars, the instrument can be used early in the operation of the GMT. The TIGER concept is a dual channel imager and low resolution spectrometer, with high contrast modes of observations to fulfill the above science goals. A long wavelength channel (LWC) will cover 7-14 μm wavelength, while a short wavelength channel (SWC) will cover the 1.5-5 μm wavelength region. Both channels will have a 30° FOV. In addition to imaging, low-resolution spectroscopy (R=300) is possible with TIGER for both the SWC and LWC, using insertable grisms.
