With modest upgrades to GRAVITY+, the Paranal Observatory will open up the extragalactic sky for milli-arcsec resolution interferometric imaging, and give access to galactic targets as faint as 22 mag. GRAVITY+ will measure the black hole masses of active galactic nuclei across cosmic times, establish whether globular clusters harbor intermediate-mass black holes, and obtain high-quality exoplanet spectra and orbits. The straightforward upgrade consists of implementing off-axis fringe tracking, an improved throughput, and laser-guide star adaptive optics for all 8m telescopes and can be divided up into several phases. Most of the upgrades will be beneficial to all VLTI instruments. Here we present a few selected science cases and outline the project, which could be implemented within a few years.","PeriodicalId":168874,"journal":{"name":"Optical and Infrared Interferometry and Imaging VII","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129583689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing the SHS instrument has a wide significance to Astrophysics and Planetary science. SHS provides integrated spectra at high R, over a wide FOV in compact designs that offer the ability to make key science measurements for a variety of planetary targets. Many planetary objects that produce UV emissions are angularly extended low brightness targets, i.e., solar wind charge exchange emission, solar system planetary atmospheres and exospheres, mapping atomic emission, comets, and the interplanetary medium. SHS could be implemented on a dedicated SmallSat or ISS that can sit and stare at its target for a long duration of time that cannot be done from the ground or on big missions.","PeriodicalId":168874,"journal":{"name":"Optical and Infrared Interferometry and Imaging VII","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129342277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The control of systematic effects is essential to fully exploit this technological advancement. Among those systematics are static phase aberrations, introduced along the instrument's optical path, which in particular affect the inferred separation of two unresolved objects within the same FOV. Here, we present how the aberrations can be measured, characterized by low-order Zernike polynomials and, most importantly, how their impact on the astrometry is corrected. The resulting astrometry corrections are verified with calibration observations of a binary before we discuss how they affect GRAVITY's measurement of the galactic center distance.","PeriodicalId":168874,"journal":{"name":"Optical and Infrared Interferometry and Imaging VII","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121167925","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The TOLIMAN space telescope program aims to develop low-cost, agile mission concepts dedicated to astrometric detection of exoplanets within 10PC, and in particularly targeting the Alpha Cen system. It accomplishes this by deploying an innovative optical and signal encoding architecture that targets the most promising technique for this critical stellar sample: high precision astrometric monitoring. Two pathfinder missions, the first a cubesat slated for 2021 launch, and the second a 10cm space telescope under development at the University of Sydney.

Such sensitive measurements can only be accomplished with the next generation of telescopes, leading to a corresponding increase in cost and complexity spectrometers. Integrated astrophotonic instruments are well-suited to address these challenges through their low-cost fabrication and compact geometries. We propose and characterize an integrated photonic gas sensor which detects the correlation between the near-infrared quasi-periodic vibronic absorption line spectrum of a gas and a silicon waveguide ring resonator transmittance comb. This technique enables lock-in amplification detection for real-time detection of faint biosignatures for reduced observation timescales and rapid exoplanetary atmosphere surveys using highly compact instrumentation.","PeriodicalId":168874,"journal":{"name":"Optical and Infrared Interferometry and Imaging VII","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128138971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
