WST, the Wide-field Spectroscopic Telescope: dispersing elements
Andrea Bianco, Michele Frangiamore, Anna Brucalassi +7
The Wide-field Spectroscopic Telescope (WST) is a proposed 12-m class facility entirely dedicated to spectroscopic surveys, combining a high-multiplex multi-object spectrograph ope…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Recent and Upcoming Upgrades for MIRC-X and MYSTIC on the CHARA Array
Noura Ibrahim, Mayra Gutierrez, John D. Monnier +17
MIRC-X and MYSTIC are six-telescope near-infrared beam (1.08-2.38 m) combiners at the CHARA Array on Mt Wilson CA, USA. Ever since the commissioning of MIRC-X (J and H bands) in…
A Precision Cryogenic Positioning Stage for Detector Dithering and Flexure Compensation
Stephen A. Smee, Stephen C. Hope, Randolph P. Hammond +20
This paper presents the design and technical progress of a precision X-Y stage for detector dithering and flexure compensation. The stage is being developed for use in the Magellan…
A Novel Freeform Slicer IFU for the Magellan InfraRed Multi-Object Spectrograph (MIRMOS)
Maren Cosens, Nicholas P. Konidaris, Gwen C. Rudie +16
The Magellan InfraRed Multi-Object Spectrograph (MIRMOS) is a planned next generation multi-object and integral field spectrograph for the 6.5m Magellan telescopes at Las Campanas…
The Blue Multi Unit Spectroscopic Explorer (BlueMUSE) on the VLT: characterization of two VPHG prototypes based on dichromated gelatin and photopolymer recording materials
Alexandre Jeanneau, Andrea Bianco, Andrew Clawson +8
Volume-phase holographic gratings (VPHGs) are widely used in astronomical spectrographs due to their adaptability and high diffraction efficiency. Most VPHGs in operation use dichr…
