Receipt: # 863-2 ----- Attempting Submission 3 (Sat Apr 06 00:00:27 GMT 2019) ----- We propose the development of CosmoVis, an open source web-based application that facilitates novel interactive analyses of large hydrodynamic simulation datasets, enabling both simulators and observers to rapidly generate synthetic absorption-line spectroscopy. Phase 1 of our project focuses on a) the development of both the back-end cloud computing infrastructure required to support real-time queries of cosmological simulations, and b) the design of the front-end interface featuring new rendering solutions to represent intergalactic and circumgalactic media. Included in Phase 1, ready for analysis, will be two snapshots from the FIRE and EAGLE simulations. Phase 2 of our project presents two scientific use cases that integrate observational methods to examine simulated data using CosmoVis. The first use case takes advantage of our interface to probe the small-scale structure of circumgalactic gas, and the second analyzes IGM/CGM large-scale structure tomography. PI Joe Burchett, an postdoctoral fellow at UC Santa Cruz is an expert in CGM/IGM observational studies with 6 refereed papers as first author. Notably, Dr. Burchett is PI of the IGM-Vis project, which combines HST/COS spectra with SDSS galaxy survey data within a 3d interactive analysis interface. CosmoVis represents a direct (but substantial extension) of IGM-Vis. Xavier Prochaska, professor at UC Santa Cruz, and Kate Rubin, professor at San Diego State Univ. are both experts in CGM observations, having among the most highly cited publications in the field. They will strongly inform the observational connection in our analysis and were key contributors to IGM-Vis. Vikram Khaire, a postdoctoral fellow at UC Santa Barbara, is an expert in IGM Ly-alpha forest statistics and simulations thereof. Cameron Hummels is a postdoctoral fellow at Caltech and expert in computational methods of modeling galaxy evolution, the circumgalactic medium (CGM), and making comparisons between simulated datasets and observations. Hummels has been PI on two successful HST theory proposals and author on over ten papers on the CGMs, five involving HST/COS data. He has wide-ranging experience with simulation data, acting as the primary developer for the Trident synthetic spectra code (a key component of CosmoVis), as a developer for the yt analysis suite and enzo hydrodynaics code, and as a member of the FIRE simulation team. David Abramov, PhD Student in Computational Media, UC Santa Cruz. David has experience developing visualization software to facilitate big data analysis. He is the lead developer of the IGM-Vis software application for analyzing intergalactic and circumgalactic medium absorption using quasar sightlines in a Cosmic Web context. Angus Forbes, Assistant Professor in Computational Media, UC Santa Cruz. Prof. Forbes is the director of the Creative Coding Lab at UC Santa Cruz. His research investigates novel techniques for visualizing and interacting with complex scientific information, and he has authored over 50 peer-reviewed publications introducing visual analytics solutions and evaluating interactive visualization techniques, including in bioinformatics, neuroscience, and astrophysics domains. Oskar Elek, Postdoctoral Researcher in Computational Media, UC Santa Cruz. Dr. Elek is an expert in computer graphics. His research focuses on physically-based rendering, real-time rendering, optically active media, Monte Carlo methods, efficient sampling, and the use of machine learning to optimize rendering solutions.
