The Tomographic Ionized-Carbon Mapping Experiment (TIME) CII Imaging Spectrometer
نویسندگان
چکیده
The Tomographic Ionized-Carbon Mapping Experiment (TIME) and TIME-Pilot are proposed imaging spectrometers to measure reionization and large scale structure at redshifts 5–9. We seek to exploit the 158 μm restframe emission of [CII], which becomes measurable at 200–300 GHz at reionization redshifts. Here we describe the scientific motivation, give an overview of the proposed instrument, and highlight key technological developments underway to enable these measurements.

DISSECTING THE HIGH-z INTERSTELLAR MEDIUM THROUGH INTENSITY MAPPING CROSS-CORRELATIONS
We explore the detection, with upcoming spectroscopic surveys, of three-dimensional power spectra of emission line fluctuations produced in different phases of the Interstellar Medium (ISM) by forbidden transitions of ionized carbon, ionized nitrogen and neutral oxygen at redshift z > 4. The emission line [CII] from ionized carbon at 157.7 μm, and multiple emission lines from carbon monoxide, a...
متن کاملGas cooling within the diffuse ISM of late–type galaxies
We combine observations of spiral galaxies in the [CII] line at 158 μm, made with the Long Wavelength Spectrometer aboard ISO, with previous data from the Kuiper Airborne Observatory to study the origin of this line, which is the main coolant of the interstellar medium at relatively low temperatures. We also use HI and CO(10) observations of these galaxies and estimate the respective line fluxe...
متن کاملResolution-enhanced Reconstruction of 3D Object Using Depth-reversed Elemental Images for Partially Occluded Object Recognitionz
Computational integral imaging (CII) is a new method for 3D imaging and visualization. However, it suffers from seriously poor image quality of the reconstructed image as the reconstructed image plane increases. In this paper, to overcome this problem, we propose a CII method based on a smart pixel mapping (SPM) technique for partially occluded 3D object recognition, in which the object to be r...
متن کاملThe Rosette molecular complex II . [ CII ] 158 μ m observations
We present an extended map in the [CII] 158 μm fine structure line of the Rosette Molecular Cloud Complex, obtained with the Far Infrared Fabry-Perot Imaging Spectrometer FIFI onboard the NASA Kuiper Airborne Observatory. Very weak but significant C+ emission was found deep in the cloud at a distance of around 25 pc from the central OB cluster. The observed intensity distribution is consistent ...
متن کاملDepth-resolved image mapping spectrometer (IMS) with structured illumination
We present a depth-resolved Image Mapping Spectrometer (IMS) which is capable of acquiring 4D (x, y, z, λ) datacubes. Optical sectioning is implemented by structured illumination. The device's spectral imaging performance is demonstrated in a multispectral microsphere and mouse kidney tissue fluorescence imaging experiment. We also compare quantitatively the depth-resolved IMS with a hyperspect...
