This is a $2,315,204.58 grant awarded by the National Aeronautics and Space Administration (NASA) to Princeton University, through its Office of Research and Project Administration, to develop and fly a diffraction-limited imaging instrument on a mid-latitude super-pressure balloon platform. The instrument will have a half-degree field of view and 0.3-arcsecond resolution, enabling transformative research in areas like exoplanet detection and weak gravitational lensing of galaxy clusters. The...
This is a $324,893.42 grant awarded by NASA's Shared Services Center to the California Institute of Technology (Caltech) to develop methods for producing accurate photometric redshifts required for the weak lensing dark energy measurements of the WFIRST space telescope. The research aims to map the relationship between WFIRST's multi-color data and galaxy redshifts, in order to minimize the need for spectroscopic training data and provide improved Bayesian priors for template-fitting redshift...
This is a $414,349.31 grant award from NASA to the University of California, Berkeley (UC Berkeley) for the WFIRST-AFTA Supernova Cosmology Program. The goal is to further develop analysis algorithms and approaches to optimize and refine the requirements for the WFIRST instrument to achieve the best possible supernova cosmology measurements. This work will build on a prior, robustly-designed program that used the WFIRST imager and integral field spectrograph to discover supernova candidates...

Princeton University is conducting this work as a prime contractor for the National Aeronautics and Space Administration (NASA). The $290,455.26 contract involves developing algorithms...
The National Aeronautics and Space Administration (NASA) awarded a $124,992.32 grant to The Trustees of Princeton University's Office of Research and Project Administration to produce and publicly release light curves for approximately 100,000 known star cluster members brighter than magnitude 16 observed in the Transiting Exoplanet Survey Satellite (TESS) full-frame images during Cycle 2. This research grant does not have a set-aside designation and was awarded on November 1, 2019 with a...
The National Aeronautics and Space Administration (NASA) awarded a $368,638.30 grant to the University of Arizona, doing business as the Arizona Board of Regents, to develop advanced data analysis and modeling frameworks that can accurately interpret future cosmological data sets from missions like the Euclid telescope, Wide-Field Infrared Survey Telescope (WFIRST), and Large Synoptic Survey Telescope (LSST). The project aims to overcome challenges in modeling baryonic effects, galaxy-dark...
This is a $1,844,173.00 grant for research awarded by the National Aeronautics and Space Administration (NASA) to The Trustees of Princeton University on October 1, 2022. The contract, which does not have a set-aside designation, supports research into the "scientific potential of diffraction-limited imaging in the near-UV to near-IR from mid-latitude ultra-long duration balloon payloads." Princeton University, a prestigious private research university, will conduct this fundamental...
This award is a $395,953.31 grant for research provided by the National Aeronautics and Space Administration (NASA) to the University of California, Berkeley to develop an open-source computational toolbox for modeling and analyzing data from galaxy redshift surveys. The goal is to enable more robust extraction of cosmological information, such as the expansion history of the universe and growth of large-scale structure, from these surveys, including those planned for the upcoming Wide-Field...
This is a $149,967 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University to develop simulation tools to evaluate the impact of mission design parameters on the ability of the Wide-Field Infrared Survey Telescope (WFIRST) Astrophysics Focused Telescope Assets (AFTA) to constrain cosmological parameters related to inflation and dark energy. The grant is focused on assessing how variations in factors like sky area, observing duration, sensitivity,...
This is a $565,916.11 grant awarded by NASA to Las Cumbres Observatory Global Telescope Network, Inc., a private non-profit organization that operates a global telescope network. The grant supports the development of a two-stage detection and classification system to analyze data from the upcoming WFIRST mission's microlensing survey. This will help identify exoplanets in the gap between previous detection methods. The project also involves analyzing data from Las Cumbres' existing...
This is a $312,508.68 grant awarded by the National Aeronautics and Space Administration (NASA) to Princeton University's Office of Research and Project Administration. The purpose of the grant is to develop algorithms for deblending and performing consistent photometry on images from the Wide Field Infrared Survey Telescope (WFIRST) and the Large Synoptic Survey Telescope (LSST). This is a crucial step for determining accurate photometric redshifts of galaxies detected by WFIRST, which is a key measurement for using galaxy shapes as a cosmological probe. The algorithms developed under this grant will be made publicly available and will inform not only the joint analysis of WFIRST and LSST data, but will be useful for a variety of future wide-field imaging surveys. There is no set-aside designation mentioned for this grant award.
