An Integral Field Unit for the Binospec Spectrograph
Daniel Fabricant, Sagi Ben-Ami, Igor Chilingarian +5
Binospec is a wide-field optical (360 to 1000 nm) spectrograph commissioned at the MMT 6.5m telescope in 2017. In direct imaging mode Binospec addresses twin 8 (wide) by 1…
Off-axis Hartmann wavefront sensing for the GMT-Consortium Large Earth Finder (G-CLEF) red camera optics
Matthew C. H. Leung, Colby A. Jurgenson, Andrew Szentgyorgyi +10
The Hartmann test is a method used to measure the wavefront error in a focal optical system, wherein a mask with a pattern of small holes is placed at the system's aperture stop. B…
The Tierras Observatory: An ultra-precise photometer to characterize nearby terrestrial exoplanets
Juliana García-Mejía, David Charbonneau, Daniel Fabricant +4
We report on the status of the Tierras Observatory, a refurbished 1.3-m ultra-precise fully-automated photometer located at the F. L. Whipple Observatory atop Mt. Hopkins, Arizona.…
Binospec: A Wide-field Imaging Spectrograph for the MMT
Daniel Fabricant, Robert Fata, Harland Epps +14
Binospec is a high throughput, 370 to 1000 nm, imaging spectrograph that addresses two adjacent 8' by 15' fields of view. Binospec was commissioned in late 2017 at the f/5 focus of…
MMT & Magellan Infrared Spectrograph
Brian McLeod, Daniel Fabricant, George Nystrom +19
The MMT and Magellan infrared spectrograph (MMIRS) is a cryogenic multiple slit spectrograph operating in the wavelength range 0.9-2.4 micron. MMIRS' refractive optics offer a 6.9…
Epsilon Aurigae: An improved spectroscopic orbital solution
Robert P. Stefanik, Guillermo Torres, Justin Lovegrove +4
A rare eclipse of the mysterious object Epsilon Aurigae will occur in 2009-2011. We report an updated single-lined spectroscopic solution for the orbit of the primary star based on…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
Hectospec, the MMT's 300 Optical Fiber-Fed Spectrograph
Daniel Fabricant, Robert Fata, John Roll +6
The Hectospec is a 300 optical fiber fed spectrograph commissioned at the MMT in the spring of 2004. A pair of high-speed six-axis robots move the 300 fiber buttons between observi…
The Type Ia Supernova 1998bu in M96 and the Hubble Constant
S. Jha, P. Garnavich, R. Kirshner +39
We present optical and near-infrared photometry and spectroscopy of the type Ia SN 1998bu in the Leo I Group galaxy M96 (NGC 3368). The data set consists of 356 photometric measure…
