This is a $366,839.47 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University to investigate how modeling errors in foreground contamination may contribute to tensions observed between data from the Wilkinson Microwave Anisotropy Probe (WMAP) and Planck space missions, as well as other cosmological measurements. The research will assess the impact of polarization foreground assumptions on determining the cosmic microwave background (CMB)...
This is a $400,105 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University, a private research university, to conduct a detailed analysis of maps and power spectra from the Wilkinson Microwave Anisotropy Probe (WMAP) and Planck missions. The research will focus on three key tasks: 1) developing a novel likelihood method to extract cosmological information while fully propagating foreground uncertainties in CMB polarization data, 2) exploring...
This is a $449,092 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University for a research project analyzing data from the Planck and WMAP missions to model and remove synchrotron and dust as cosmic microwave background (CMB) foregrounds. The work will address three key questions on the variation in CMB foregrounds and their impact on CMB measurements. This grant is not associated with a set-aside contract. The Johns Hopkins University is a...

This is a $352,709 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Chicago to utilize upcoming polarization data from the Planck spacecraft to reconstruct the earliest observable epochs of cosmic inflation in a model-independent fashion. The research aims to improve our understanding of the dynamics at the beginning of the observable universe through advanced techniques that go beyond standard approximations. This grant supports NASA's investment in...
This is a $323,613 grant awarded by the National Aeronautics and Space Administration (NASA) to The Trustees of Princeton University, doing business as Princeton University, to conduct research related to the analysis of data from the Planck satellite. The grant supports the production of seven maps of the polarized sky from 30 to 353 gigahertz, which have been transformative for both cosmology and the study of the magnetized interstellar medium. The work is being performed at Princeton...
The National Aeronautics and Space Administration (NASA) awarded a $217,332.00 grant to the University of Chicago for research and development of optical and optical coupling technologies for future satellite-based Cosmic Microwave Background (CMB) missions. The research aims to develop anti-reflection coatings, filters, and feedhorns that will enable high-frequency, high-performance CMB measurements from 30-400 GHz to separate cosmological signals from foregrounds. The technologies being...
This federal contract award, valued at $452,208.00, was granted by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University, a private, non-profit research university in Baltimore, Maryland. The contract is for a research project titled "LARGE ANGULAR SCALE CMB ANOMALIES A MODERN IN DEPTH ANALYSIS OF SYSTEMATICS, FOREGROUNDS, AND COSMOLOGY" and does not have a set-aside designation. The project, identified as 23-ADAP23-0084, will conduct an in-depth...
This federal contract award, with ID 80NSSC20K0445, is a $412,970 grant for research awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University, a private research university in Baltimore, Maryland. The grant is focused on studying the essential information contained in the polarization signals of the Cosmic Microwave Background (CMB), which may hold evidence of primordial gravitational waves produced during the inflationary period of the early...
This is a grant award from the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University (JHU) to analyze data from the Planck and Wilkinson Microwave Anisotropy Probe (WMAP) missions and resolve discrepancies between their cosmic microwave background (CMB) measurements. The $362,846.84 grant will fund research to: 1) quantify how Planck's CMB lensing data impacts cosmological parameter constraints compared to WMAP; 2) assess if WMAP's optical depth measurement is too high; 3) test the consistency of WMAP and Planck's CMB power spectra and parameter constraints; and 4) resolve discrepancies in their foreground models. The research aims to create a consensus CMB dataset that combines the best elements of both Planck and WMAP data. This work supports NASA's objectives around understanding the origin and evolution of the universe.
