The Hobby-Eberly Telescope VIRUS Parallel Survey (HETVIPS)
Gregory R. Zeimann, Maya H. Debski, Donald P. Schneider +6
The Hobby-Eberly Telescope (HET) VIRUS Parallel Survey (HETVIPS) is a blind spectroscopic program that sparsely covers approximately two-thirds of the celestial sphere and consists…
The HETDEX Instrumentation: Hobby-Eberly Telescope Wide Field Upgrade and VIRUS
Gary J. Hill, Hanshin Lee, Phillip J. MacQueen +46
The Hobby-Eberly Telescope (HET) Dark Energy Experiment (HETDEX) is undertaking a blind wide-field low-resolution spectroscopic survey of 540 square degrees of sky to identify and…
Builders Instead of Consumers: Training Astronomers in Instrumentation & Observation
Sarah Tuttle, Hanshin Lee, Cynthia Froning +1
The astronomy community has made clear our shared scientific vision in the Astro2010 decadal survey. Who will build this future? The cost and scarcity of telescope resources makes…
Error analysis of moment-based modal wavefront sensing
Hanshin Lee
The shape of a focus-modulated point spread function (PSF) is used as a quick visual assessment tool of aberration modes in the PSF. Further analysis in terms of shape moments can…
Mass production of volume phase holographic gratings for the VIRUS spectrograph array
Taylor S. Chonis, Amy Frantz, Gary J. Hill +7
The Visible Integral-field Replicable Unit Spectrograph (VIRUS) is a baseline array of 150 copies of a simple, fiber-fed integral field spectrograph that will be deployed on the Ho…
LRS2: the new facility low resolution integral field spectrograph for the Hobby-Eberly Telescope
Taylor S. Chonis, Gary J. Hill, Hanshin Lee +2
The second generation Low Resolution Spectrograph (LRS2) is a new facility instrument for the Hobby-Eberly Telescope (HET). Based on the design of the Visible Integral-field Replic…
The Influence of Motion and Stress on Optical Fibers
Jeremy D. Murphy, Gary J. Hill, Phillip J. MacQueen +13
We report on extensive testing carried out on the optical fibers for the VIRUS instrument. The primary result of this work explores how 10+ years of simulated wear on a VIRUS fiber…
Methods for evaluating the performance of volume phase holographic gratings for the VIRUS spectrograph array
Taylor S. Chonis, Gary J. Hill, J. Christopher Clemens +2
The Visible Integral Field Replicable Unit Spectrograph (VIRUS) is an array of at least 150 copies of a simple, fiber-fed integral field spectrograph that will be deployed on the H…
Design and construction progress of LRS2-B: a new low resolution integral field spectrograph for the Hobby-Eberly Telescope
Taylor S. Chonis, Hanshin Lee, Gary J. Hill +3
The upcoming Wide-Field Upgrade (WFU) has ushered in a new era of instrumentation for the Hobby-Eberly Telescope (HET). Here, we present the design, construction progress, and lab…
Proto-Model of an Infrared Wide-Field Off-Axis Telescope
Sanghyuk Kim, Soojong Pak, Seunghyuk Chang +5
We develop a proto-model of an off-axis reflective telescope for infrared wide-field observations based on the design of Schwarzschild-Chang type telescope. With only two mirrors,…
The Fibre Multi-Object Spectrograph (FMOS) for Subaru Telescope
Masahiko Kimura, Toshinori Maihara, Fumihide Iwamuro +39
Fibre Multi-Object Spectrograph (FMOS) is the first near-infrared instrument with a wide field of view capable of acquiring spectra simultaneously from up to 400 objects. It has be…
