Scientifically, CIBER-2 follows on the results of CIBER-1, which has detected near-infrared background anisotropy. CIBER-1 has also produced leading results on the absolute brightness of the background, the spectrum of diffuse galactic light, the spectrum of Zodiacal light, and constraints on the Zodiacal light foreground from Fraunhofer line observations. CIBER-2 builds on the measurement techniques developed and successfully demonstrated by CIBER-1. With high-sensitivity, multi-color anisotropy measurements, CIBER-2 will elucidate the history of interhalo light production and carry out a deep search for extragalactic background fluctuations associated with the epoch of reionization. A plausible interpretation of the infrared background anisotropy detected by CIBER-1, Spitzer and AKARI is interhalo light from stars tidally stripped from their parent galaxies during galaxy mergers. Based on the rms amplitude of the anisotropy, interhalo light produces approximately half of the background, representing a major branch of light production. Probing the history of interhalo light through improved anisotropy measurements using multiple bands and correlating with tracers of large-scale structure is essential to understand its role in the cosmic history of star formation. The first generation of stars and their remnants are likely responsible for the reionization of the intergalactic medium, observed to be ionized out to distant quasars at a redshift of 6. The total luminosity produced by first stars is uncertain, but a lower limit can be placed assuming a minimal number of photons to produce and sustain reionization. This 'minimal' extragalactic background component associated with reionization is detectable in fluctuations at the design sensitivity of CIBER-2. The CIBER-2 instrument is optimized for sensitivity to surface brightness in a short sounding rocket flight. The instrument consists of a 28 cm wide-field telescope operating in 6 spectral bands between 0.5 and 2.0 um, cooled to a temperature of 77 K with a liquid-nitrogen-cooled cryostat. Images are composed using 3 focal plane assemblies operating H2RG detector arrays. The instrument is currently being fabricated with international partners and nearing completion. CIBER-2 will extend the CIBER-1 anisotropy meausurements from the near-infrared into the optical, where the EOR and IHL components of the extragalactic background can be cleanly distinguished and separated. We will study the history of IHL production by implementing a multi-band cross-correlation analysis, and use this information to carry out a deep search for an EOR component. We plan joint observations with weak lensing maps, with an optimized set of filter bands to measure spectral cross-correlations, to fully elucidate the history of IHL light production. In addition, our international partners will measure the absolute brightness of the background at optical to near-infrared wavelengths using 3 specialized linear-variable filter spectrometers.","destinations":[{"lkuCodeId":1547,"code":"OUTSIDE_SOLAR_SYSTEM","description":"Outside the Solar System","lkuCodeTypeId":526,"lkuCodeType":{"codeType":"DESTINATION_TYPE","description":"Destination Type"}}],"startYear":2016,"startMonth":2,"endYear":2021,"endMonth":1,"statusDescription":"Completed","principalInvestigators":[{"contactId":192468,"canUserEdit":false,"firstName":"James","lastName":"Bock","fullName":"James J Bock","fullNameInverted":"Bock, James J","middleInitial":"J","primaryEmail":"jjb@astro.caltech.edu","publicEmail":false,"nacontact":false}],"programDirectors":[{"contactId":332808,"canUserEdit":false,"firstName":"Michael","lastName":"Garcia","fullName":"Michael A Garcia","fullNameInverted":"Garcia, Michael A","middleInitial":"A","publicEmail":false,"nacontact":false}],"programManagers":[{"contactId":123302,"canUserEdit":false,"firstName":"Dominic","lastName":"Benford","fullName":"Dominic J Benford","fullNameInverted":"Benford, Dominic J","middleInitial":"J","primaryEmail":"dominic.j.benford@nasa.gov","publicEmail":true,"nacontact":false}],"coInvestigators":[{"contactId":474564,"canUserEdit":false,"firstName":"Toshio","lastName":"Matsumoto","fullName":"Toshio Matsumoto","fullNameInverted":"Matsumoto, Toshio","primaryEmail":"matsumo@ir.isas.jaxa.jp","publicEmail":false,"nacontact":false},{"contactId":341474,"canUserEdit":false,"firstName":"Michael","lastName":"Zemcov","fullName":"Michael B Zemcov","fullNameInverted":"Zemcov, Michael B","middleInitial":"B","primaryEmail":"zemcov@cfd.rit.edu","publicEmail":false,"nacontact":false},{"contactId":437466,"canUserEdit":false,"firstName":"Shuji","lastName":"Matsuura","fullName":"Shuji Matsuura","fullNameInverted":"Matsuura, Shuji","primaryEmail":"matsuura.shuji@kwansei.ac.jp","publicEmail":false,"nacontact":false},{"contactId":34126,"canUserEdit":false,"firstName":"Asantha","lastName":"Cooray","fullName":"Asantha Cooray","fullNameInverted":"Cooray, Asantha","primaryEmail":"acooray@uci.edu","publicEmail":false,"nacontact":false},{"contactId":92841,"canUserEdit":false,"firstName":"Daehee","lastName":"Lee","fullName":"Daehee Lee","fullNameInverted":"Lee, Daehee","primaryEmail":"dhlee@kasi.re.kr","publicEmail":false,"nacontact":false},{"contactId":299221,"canUserEdit":false,"firstName":"Lucy","lastName":"Viramontes","fullName":"Lucy A Viramontes","fullNameInverted":"Viramontes, Lucy A","middleInitial":"A","primaryEmail":"lucy.molina@caltech.edu","publicEmail":false,"nacontact":false},{"contactId":375105,"canUserEdit":false,"firstName":"Phil","lastName":"Korngut","fullName":"Phil Korngut","fullNameInverted":"Korngut, Phil","primaryEmail":"pkorngut@caltech.edu","publicEmail":false,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"SMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4909,"organizationName":"Science Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"APRA","active":true,"description":"

","parentProgram":{"active":true,"description":"There are four Program elements within the Astrophysics Division that execute technology development activities: Cosmic Origins (COR), Physics of the Cosmos (PCOS), Exoplanet Exploration (EXEP), and the Astrophysics Research Program. Technology efforts in the Division are procured through both directed and competed processes.
The PCOS, COR, and EXEP programs develop and operate the Division’s strategic science missions. Thus, each of these programs conduct strategic technology development activities to enable future missions and to support early phase mission development. Each has a formal Technology Development Plan to guide its technology development activities, and maintains an annual report that documents the status of currently funded activities. Annual assessments identify future technology development needs based on the science goals of each program.
The PCOS, COR, and EXEP Programs conduct competed technology development efforts through a Research Opportunities in Space and Earth Science (ROSES) element known as Strategic Astrophysics Technology (SAT) that specifically targets technology developments that bridge the technology readiness level (TRL) 3-6 gap. SAT developed technologies are essential to enable strategic missions that specifically address the key science goals of the Astrophysics Decadal Survey recommendations. The three SAT elements for PCOS, COR, and EXEP are named Technology Development for Physics of the Cosmos (TPCOS), Technology Development for Cosmic Origins Program (TCOP), and Technology Development for Exo-Planet Missions (TDEM) respectively. In contrast to these competed efforts, each program also conducts directed technology development activities that are carried out as elements of specific strategic science missions during early development phases.
