Expected performance and simulated observations of the instrument HARMONI at the European Extremely Large Telescope (E-ELT)
Proceedings of SPIE - The International Society for Optical Engineering 7735:PART 1 (2010)
Abstract:
HARMONI has been conceived as a workhorse visible and near-infrared (0.47-2.45 microns) integral field spectrograph for the European Extremely Large Telescope (E-ELT). It provides both seeing and diffraction limited observations at several spectral resolutions (R= 4000, 10000, 20000). HARMONI can operate with almost any flavor of AO (e.g. GLAO, LTAO, SCAO), and it is equipped with four spaxel scales (4, 10, 20 and 40 mas) thanks to which it can be optimally configured for a wide variety of science programs, from ultra-sensitive observations of point sources to highangular resolution spatially resolved studies of extended objects. In this paper we describe the expected performance of the instrument as well as its scientific potential. We show some simulated observations for a selected science program, and compare HARMONI with other ground and space based facilities, like VLT, ALMA, and JWST, commenting on their synergies and complementarities. © 2010 Copyright SPIE - The International Society for Optical Engineering.HARMONI: A single-field wide-band integral-field spectrograph for the European ELT
Proceedings of SPIE - The International Society for Optical Engineering 7735:PART 1 (2010)
Abstract:
We describe the results of a Phase A study for a single field, wide band, near-infrared integral field spectrograph for the European Extremely Large Telescope (E-ELT). HARMONI, the High Angular Resolution Monolithic Optical & Nearinfrared Integral field spectrograph, provides the E-ELT's core spectroscopic requirement. It is a work-horse instrument, with four different spatial scales, ranging from seeing to diffraction-limited, and spectral resolving powers of 4000, 10000 & 20000 covering the 0.47 to 2.45 μm wavelength range. It is optimally suited to carry out a wide range of observing programs, focusing on detailed, spatially resolved studies of extended objects to unravel their morphology, kinematics and chemical composition, whilst also enabling ultra-sensitive observations of point sources. We present a synopsis of the key science cases motivating the instrument, the top level specifications, a description of the opto-mechanical concept, operation and calibration plan, and image quality and throughput budgets. Issues of expected performance, complementarity and synergies, as well as simulated observations are presented elsewhere in these proceedings[1]. © 2010 Copyright SPIE - The International Society for Optical Engineering.KMOS: Assembly, integration and testing of three 0.8-2.5 micron spectrographs
Proceedings of SPIE - The International Society for Optical Engineering 7735:PART 1 (2010)
Abstract:
KMOS is a second generation instrument in construction for use at the European Southern Observatory (ESO) Very Large Telescope (VLT). It operates in the near-infrared (0.8 to 2.5 microns) and employs 24 deployable, image slicing integral field units (IFUs) feeding three spectrographs. The spectrographs are designed and built by a partnership of the University of Oxford and Rutherford Appleton Laboratories (RAL). We describe the assembly, integration and alignment procedures involved in the construction of these spectrographs in detail. We also present the results of the cryogenic optical tests, including the first data taken through the full spectrograph optical train and the details of the test facility and procedures involved. © 2010 Copyright SPIE - The International Society for Optical Engineering.Recent progress on the KMOS multi-object integral-field spectrograph for ESO VLT
Proceedings of SPIE - The International Society for Optical Engineering 7735:PART 1 (2010)
Abstract:
KMOS is a near-infrared multi-object integral-field spectrometer which is one of a suite of second-generation instruments under construction for the VLT. The instrument is being built by a consortium of UK and German institutes working in partnership with ESO and is now in the manufacture, integration and test phase. In this paper we present an overview of recent progress with the design and build of KMOS and present the first results from the subsystem test and integration. © 2010 Copyright SPIE - The International Society for Optical Engineering.The Oxford SWIFT spectrograph: First commissioning and on-sky results
