Near Infrared Observations of GQ Lup b Using the Gemini Integral Field Spectrograph NIFS
We present new JHK spectroscopy (R ∼ 5000) of GQ Lup b, acquired with the near-infrared integral field spectrograph NIFS and the adaptive optics system ALTAIR at the Gemini North telescope. Angular differential imaging was used in the J and H bands to suppress the speckle noise from GQ Lup A; we show that this approach can provide improvements in signal-to-noise ratio (S/N) by a factor of 2 − 6...
متن کاملScience with NIFS, Australia's First Gemini Instrument
The Near-infrared Integral Field Spectrograph (NIFS) will be Australia's rst Gemini instrument. NIFS is a near-infrared, imaging spectrograph that will be used with the ALTAIR facility adaptive optics system on Gemini North to perform near di ractionlimited imaging spectroscopy over a 3:0 3:0 eld-of-view with 0.1 wide slitlets and a spectral resolving power of 5300. NIFS will operate in the wav...
متن کاملKMOS: an infrared multi-integral field spectrograph for the VLT
We describe a proposed 2 generation instrument (KMOS) for the ESO VLT which will deliver a unique multiple deployable integral field capability in the near-infrared (1-2.5ìm). The science drivers for such an instrument are presented and linked to the functional specification. The overall instrument concept is discussed in the context of two proposed solutions for delivering a deployable integra...
متن کاملFLEX: the first light explorer. A fully OH-suppressed near-infrared integral field spectrograph
FLEX is a concept for a fully OH suppressed near infrared integral field spectrograph, being developed at the AAO. FLEX will be the first instrument to employ fibre Bragg gratings for OH suppression, a radical new technology which cleanly suppresses the atmospheric OH emission lines at 30dB whilst maintaining a high overall throughout of ~90%. In this paper we simulate the expected performance ...
متن کاملKMOS: an infrared multiple object integral field spectrograph for the ESO VLT
We describe the design of a 2 generation instrument for the ESO VLT which will deliver a unique multiple deployable integral field capability in the near-infrared (1-2.5μm). The science drivers for the instrument are presented and linked to the functional specification. The baseline instrument concept is described with emphasis on technological innovations. Detailed discussions of specific tech...
