Instruments on the Baade telescope
- The Inamori-Magellan Areal Camera & Spectrograph (IMACS) is a highly-versatile wide field imager, longslit, and multislit spectrograph. It offers a large range of modes:
- 15.5' x 15.5' field of view at 0.11 arcsec/pixel imaging with the f/4 camera.
- 27.2' x 27.2' field of view at 0.20 arcsec/pixel imaging with the f/2 camera.
- Longslit spectroscopy, with a slit-viewing option.
- Multislit spectroscopy, with a Nod-and-Shuffle option.
- Integral Field Spectroscopy with the Durham-built IFU.
- GISMO is an image-slicing reformatter that installs into the slitmask area of IMACS at the focal surface of the Baade telescope. Its purpose is to slice up into 16 sectors a ~4'x4' area at the center of the IMACS f/4 field and reimage them back in the focal plane at the same scale and f-ratio, but covering the entire f/4 field. This allows multislit spectroscopy of densely packed fields ( >5 targets/sq arcmin) whose spectra would normally interfere in the central area, but not once the slices have been separated.
- The Maryland-Magellan Tunable Filter (MMTF) is a narrow-band filter which is tunable in both central wavelength and transmission bandpass, similar to the old Taurus Tunable Filter. The MMTF is based on a Fabry-Perot etalon that operates in low orders (close plate settings) to provide a large "monochromatic spot" (region of constant wavelength) across the field of view. Its tunability, sensitivity, narrow bandpass, and wide field make this a unique capability applicable to a wide range of programs. Observers intending to request time with the MMTF should contact Sylvain Veilleux (veilleux -@- astro.umd.edu) before applying.
- The Multi-Object Echelle (MOE) transforms IMACS into a spectrograph with properties similar to ESI on Keck, however with a significant multiplexing capability. MOE on IMACS permits crossed-dispersed echelle spectra to be obtained over the 15' x 15' field of the f/4 camera, accomplished by the use of a grating and cross-dispersing prism mounted on the IMACS grating wheel.
- FourStar is a wide-field (11' x 11' at 0.16 arcsec per pixel) near-infrared imager using four HAWAII-2RG array detectors, equipped with Y, J, H, and Ks filters, plus other narrower-band filters available by collaboration with the instrument PI Eric Persson (persson -@- obs.carnegiescience.edu).
- The Folded port InfraRed Echellette (FIRE) provides R~6000 cross-dispersed spectroscopy covering the entire near-IR, as well as a lower-resolution (R=2500 in J, R=1300 in H, R=900 in K), higher-throughput mode. A new 0.45" slit has been installed.
- The Magellan Echellette Spectrograph (MagE) complements MIKE by pushing further into the blue (3100 - 10000 Å) and having a lower resolution (R~4000 through the 1 arcsec slit), is capable of going significantly fainter.
Instruments on the Clay telescope
- Megacam is a CCD mosaic optical camera covering a 25' x 25' field of view at 0.08 arcsec per pixel with SDSS u', g', r', i' and z' filters. A special g'+r' filter is available by arrangement.
- The Magellan Adaptive Optics (MagAO) facility is a natural guide star system for the Clay telescope that uses a high-order wavefront sensor and adaptive secondary mirror to deliver near diffraction-limited imaging performance simultaneously with both an optical (VisAO) and an infrared (Clio2) camera. Those interested in using MagAO should contact Laird Close (lclose -@- as.arizona.edu) before submitting a proposal.
- The Magellan Inamori Kyocera Echelle (MIKE) is a high-throughput double echelle spectrograph.
- LDSS3 is a high-efficiency, wide-field multislit spectrograph. LDSS3 is available in shared-risks mode as a facility instrument with the Sloan filter set for imaging, and VPH grisms for spectroscopy. A CCD with much-improved red sensitivity is now the default detector for LDSS3, although programs focusing on bluer wavelengths will have the option to use the original CCD in certain blocks.
- The Planet Finder Spectrograph (PFS) is a high resolution echelle spectrograph optimized for precision radial velocity measurements. PFS is a PI instrument and is currently only available via collaborative arrangement with the instrument team. Contact Paul Butler (bluaper -@- gmail.com) and/or Steve Shectman (shec -@- obs.carnegiescience.edu) before submitting a proposal.
- The Michigan/Magellan Fibre System (M2FS) is a new fiber-fed, multi-object, optical spectrograph with both high (20K < R < 34K) and low (1,500 < R < 2,700) resolution modes offering full wavelength coverage from 370 to 950nm for up to 256 objects over a 30 arcmin field of view. M2FS is a PI instrument and is only available via collaborative arrangement with the instrument team. Contact Mario Mateo (mmateo -@- umich.edu) before submitting a proposal.
- The Parallel Imager for Southern Cosmology Observations (PISCO) provides simultaneous imaging in the 4 SDSS bands g', r', i', and z' over a 7.3 x 5.4 arcminute field of view at 0.11 arcsec/pixel. PISCO is a PI instrument and is only available via collaborative arrangement with the instrument team. Contact Tony Stark (astark -@- cfa.harvard.edu) before submitting a proposal.
