+ | ===== Proposal Information ===== | ||
+ | |||
+ | ==== Caltech community ==== | ||
+ | |||
+ | Members of the Caltech community* are invited to propose observations with | ||
+ | the Caltech Submillimeter Observatory. | ||
+ | |||
+ | The CSO consists of a 10.4 m diameter Leighton telescope on Mauna Kea, Hawaii. With | ||
+ | [[cso:telescope:dsos:dsos|active adjustment]], the surface accuracy is about 13 µm rms. | ||
+ | The instrument suite supports spectroscopy and continuum imaging at wavelengths between 2 mm and 350 μm | ||
+ | |||
+ | |||
+ | A full complement of [[cso:instruments:heterodyne:heterodyne|heterodyne receivers]] covers | ||
+ | the atmospheric windows from 177 to 920 GHz. | ||
+ | New [[cso:instruments:heterodyne:sidecab_rxb|230 GHz and 460 GHz receivers]] | ||
+ | have 4 GHz IF bandwidths and fully automated | ||
+ | (synthesized) local oscillator tuning. | ||
+ | Older receivers for the 345 GHz, 650 GHz, and 850 GHz atmospheric windows | ||
+ | have 1 GHz IF bandwidths and require manual tuning. | ||
+ | In addition, a wide band (4 GHz), manually tuned [[cso:instruments:heterodyne:tuning:barney|345 GHz receiver]] | ||
+ | is available for special projects. | ||
+ | DSB receiver noise temperatures are about 40 K at 230 GHz; 50 K or 90 K at 345 GHz, depending | ||
+ | on receiver; 40 K at 460 GHz; 230 K at 650 GHz; and 400 K at 850 GHz. | ||
+ | Two FFTS spectrometers are available. | ||
+ | The high resolution [[cso:instruments:heterodyne:ffts1|FFTS1]] provides 8192 channels across a selectable | ||
+ | bandwidth of 1 GHz or 500 MHz, which is tunable across the 4 GHz IF band. | ||
+ | The new wide band [[cso:instruments:heterodyne:ffts1|FFTS2]] provides 16384 channels across the full 4 GHz IF band. | ||
+ | |||
+ | [[cso:instruments:music:music|MUSIC]] is multiwavelength MKID camera. In its present configuration, MUSIC has an 11 x 11 arcmin field of view, three simultaneous wavelengths (1.1 mm , 1.4 mm, and 2.1 mm), and 250-300 operational detectors. MUSIC is currently available for science observations although instrument upgrades continue. Measured sensitivities are 15-30 mJy beam<sup>-1</sup> hr<sup>0.5</sup> for small sources, depending on wavelength. MUSIC is an ideal instrument for surveying for dusty, star-forming galaxies and for star-forming regions in our own Galaxy and, with its unique, extended wavelength coverage, for studying galaxy clusters with the Sunyaev-Zeldovich effect. The MUSIC instrument team plans surveys covering many square degrees and roughly 200 galaxy clusters and welcomes inquiries about collaboration on these surveys. | ||
+ | |||
+ | [[http://www.submm.caltech.edu/~sharc|SHARC II]] is a 12×32 pixel bolometer camera for 350 μm and 450 μm. In good | ||
+ | weather, its sensitivity is about 1 Jy beam<sup>-1</sup> s<sup>0.5</sup> over a 2.5 x 0.9 | ||
+ | arcmin field of view. | ||
+ | |||
+ | The [[http://lennon.astro.northwestern.edu/SHARP|SHARP]] polarimeter functions at 350 µm in conjunction with SHARC II. Proposals for | ||
+ | SHARP will be considered provided they do not request sources that overlap the | ||
+ | instrument team's [[http://lennon.astro.northwestern.edu/SHARP/science.html|survey]] of low-mass Class 0 cores. | ||
+ | Proposers are encouraged to contact the instrument PI, Giles Novak | ||
+ | <g-novak@northwestern.edu> to explore collaborative arrangements. | ||
+ | In return for the instrument and for observing and data analysis assistance, observers using SHARP must | ||
+ | support an amount of observing time for the SHARP team. | ||
+ | |||
+ | [[http://casa.colorado.edu/~jglenn/research/zspec.html|Z-Spec]], a 195-310 GHz grating spectrometer, is expected to be available starting in mid 2014. | ||
+ | [[http://astro.cornell.edu/~spifiweb/zeus2|ZEUS2]], a grating spectrometer for 350 μm, 450 μm, and 650 µm, may become available later. | ||
+ | |||
+ | Remote observations are supported, subject to some restrictions, | ||
+ | with the 230 GHz and 460 GHz receivers, | ||
+ | with MUSIC, with SHARC, and with SHARP. | ||
+ | For the other instruments, | ||
+ | investigators normally travel to the telescope for their observations. | ||
+ | CSO | ||
+ | staff will provide orientation and limited training for novice observers. | ||
+ | |||
+ | |||
+ | For | ||
+ | safety, two (or more) persons must be present at the telescope whenever | ||
+ | anyone is there. | ||
+ | University of Hawaii at Hilo undergraduate volunteers are sometimes | ||
+ | available to assist with in person observations. | ||
+ | Observers who go to the telescope are responsible for travel to Hale Pohaku and for lodging and | ||
+ | subsistence there. Subject to Caltech policies, CSO 4WD vehicles are | ||
+ | provided for transport between HP and the telescope. Depending on circumstances, | ||
+ | CSO vehicles may be available for Caltech staff to travel between Hilo and HP. | ||
+ | Observers should expect to contribute to the costs of cryogens for SHARC/SHARP, Bolocam, and Z-Spec and, when | ||
+ | necessary, the travel expenses of instrument support personnel. | ||
+ | |||
+ | Proposals for observations will be considered as they are received. | ||
+ | Proposals should include an abstract and scientific justification. | ||
+ | Proposals should also describe a plan for reducing data with | ||
+ | publicly available tools or by collaborative arrangements with | ||
+ | experienced CSO observers or relevant instrument team members. | ||
+ | Please use the CSO proposal template. In addition, please list | ||
+ | (1) publications by any proposal investigators using CSO data since | ||
+ | 2010; (2) all students and postdocs who have used the CSO since 2010; | ||
+ | and (3) students who have obtained a PhD using the CSO. Send proposals | ||
+ | to Simon Radford, CSO Operations Manager <sradford@caltech.edu>. | ||
+ | Proposals will be reviewed by the CSO director and an advisory committee. | ||
+ | |||
+ | The [[http://cso.caltech.edu|CSO web pages]] have more information about the | ||
+ | telescope and instrumentation, including atmospheric transmission spectra. | ||
+ | Please address any questions to Simon | ||
+ | Radford, CSO Operations Manager <sradford@caltech.edu>. | ||
+ | |||
+ | |||
+ | === Eligibility === | ||
+ | |||
+ | Caltech faculty, students, and staff may propose CSO observations in response to this call. | ||
+ | |||
+ | Members of the IPAC and JPL staff will be invited to submit proposals | ||
+ | through a separate call for JPL proposals. | ||
