The properties of the SGL are remarkable: it offers maximum light amplification of ~1e11 and angular resolution of ~1e-10 arcsec. A probe with a 1-m telescope in the SGL focal region can image an exoplanet at 30 pc with 10-kilometer resolution on its surface, sufficient to observe seasonal changes, oceans, continents, surface topography. We reached and exceeded all objectives set for our study: We developed a new wave-optical approach to study the imaging of exoplanets while treating them as extended, resolved, faint sources at large but finite distances. We properly accounted for the solar corona brightness. We developed deconvolution algorithms and demonstrated the feasibility of high-quality image reconstruction under realistic conditions. We have proven that multipixel imaging and spectroscopy of exoplanets with the SGL are feasible. We have developed a new mission concept that delivers an array of optical telescopes to the SGL focal region relying on three innovations: i) a new way to enable direct exoplanet imaging, ii) use of smallsats solar sails fast transit through the solar system and beyond, iii) an open architecture to take advantage of swarm technology. This approach enables entirely new missions, providing a great leap in capabilities for NASA and the greater aerospace community. Our results are encouraging as they lead to a realistic design for a mission that will be able to make direct resolved images of exoplanets in our stellar neighborhood. It could allow exploration of exoplanets relying on the SGL capabilities decades, if not centuries, earlier than possible with other extant technologies. The architecture and mission concepts for a mission to the strong interference region of the SGL are promising and should be explored further.", "author_list": "Turyshev, Slava G. and Shao, Michael, el al." }, { "title": "Using the Web of Science API to meet funding application requirements", "type": "publication_deliverable", "publication_date": "2019", "publisher": "Caltech Library", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20221020-215019353", "abstract": "Applying for grants and other funding\nsupport, and mustering the necessary data\nfor documentation, can be a complicated\nand time-consuming process, fraught with\nexacting requirements and protocols.

Experiments were carried out in the Caltech T5 hypervelocity shock tunnel and the Caltech Mach 4 Ludwieg tube. The tests used 5-degree half-angle cones (at zero angle of attack) equipped near the front of the cone with an injector consisting of either discrete holes or a porous section. Gaseous CO\u2082, argon (Ar) and air were injected into the boundary layer and the effect on boundary layer stability was evaluated by optical visualization, heat flux measurements and numerical simulation. In T5, tests were carried out with CO\u2082 in the free stream as well as injection. Injection experiments in T5 were inconclusive; however, experiments with mixtures of air/CO\u2082 in the free stream demonstrated a clear stabilizing effect, limiting the predicted amplification N-factors to be less than 13. During the testing activities in T5, significant improvements were made in experimental technique and data analysis. Testing in the Ludwieg tube enabled optical visualization and the identification of a shear-layer like instability downstream of the injector. Experiments showed and numerical simulation confirmed that injection has a destabilizing influence beyond a critical level of injection mass flow rate. A modified injection geometry was tested in the Ludwieg tube and we demonstrated that it was possible to cancel the shock wave created by injection under carefully selected conditions. However, computations indicate and experiments demonstrate that shear-layer like flow downstream of the porous wall injector is unstable and can transition to turbulence while the injected gas is mixing with the free stream. We conclude that the idea of using vibrational relaxation to delay boundary layer transition is a sound concept but there are significant practical issues to be resolved to minimize the flow disturbance associated with introducing the vibrationally-active gas into the boundary layer.", "author_list": "Shepherd, Joseph E." }, { "title": "Airships: A New Horizon for Science", "type": "publication_deliverable", "publication_date": "2014-02-26", "publisher": "Keck Institute for Space Studies", "doi": "10.26206/PY4M-YN28", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20160303-135927410", "abstract": "The \"Airships: A New Horizon for Science\" study at the Keck Institute for\nSpace Studies investigated the potential of a variety of airships currently\noperable or under development to serve as observatories and science\ninstrumentation platforms for a range of space, atmospheric, and Earth science.\nThe participants represent a diverse cross-section of the aerospace sector,\nNASA, and academia.

Using 2012 data, we examine various noise discriminants, specifically pulse shape discriminants (isolated, flat, spike, and triangle pulse shape), the isolation based filters, as well as other statistics, for the Hadronic Calorimeter (HCAL) barrel and endcap anomalous signals. Using these, we determine which areas of the detector are persistently noisy, as well as the performance of the algorithms on 2012 data. Overall, read-out-box 8 is particularly noisy this year, and the endcap regions have an unusual number of channels flagging as noise, but these channels are contributing low energy so the current algorithms are still acceptable.

Characterization of this channel relies on the accurate prediction of lepton detection efficiency and resolution, but currently used algorithms for prediction of these detector effects are computationally demanding. This project developed a validation procedure for a faster simulation algorithm written by the Caltech group, and showed its adequacy for predicting efficiency and resolution. Another issue analyzed in lepton detection was the use of multivariate analysis techniques, such as boosted decision trees, for reconstruction of the actual lepton energies from detected values, in order to discover whether the current reconstruction algorithms can be improved. Some questions outside of the scope of lepton detection were also analyzed, such as the distributions of the two intermediate Z in the HZZ4l decay.
