  1. Astronomy Re-envisioned: Investigating the Physics of Galaxy Evolution with Machine Learning

    February 15, 2024 Lectures

    Astronomical imaging of galaxies reveals how they formed and evolved. While spectroscopy is necessary for measuring galaxies' physical properties, such as their cold gas content or metallicity, it...

  2. Simulation of High-contrast Polarimetric Observations of Debris Disks with the Roman Coronagraph Instrument

    January 18, 2024 Lectures

    The Nancy Grace Roman Space Telescope Coronagraph Instrument will enable the polarimetric imaging of debris disks and inner dust belts in the optical and near-infrared wavelengths, in addition to the high-contrast...

  3. Transits in the Roman Galactic EXoplanet Survey (TRExS): Potential Breakthroughs in Exoplanet Demographics Enabled by Roman's Unprecedented Survey Depth and Volume

    November 16, 2023 Lectures

    The Roman Galactic Bulge Time Domain Survey (GBTDS) will monitor 100s of millions of stars toward the center of the Milky Way, providing a powerful dataset that can be exploited for a number of scientific...

  4. The Detection of M-L-T-Y Dwarfs Belonging to our Milky Way Disks and Stellar Halo with the Roman Space Telescope

    October 19, 2023 Lectures

    How many low-mass stars are in the Milky Way? And where are these low-mass stars and free-floating planet-like objects in our Galaxy? One can use the High Latitude Survey with the Roman Space Telescope...

  5. History of the Roman Observatory Design, and Current Build Status

    September 21, 2023 Lectures

    This talk presents the history of the design of what is now the Nancy Grace Roman Space Telescope observatory. Significant evolution from the 2010 Astrophysics decadal submission to flight is traced, with...

  6. Roman Coronagraph Instrument Deformable Mirrors

    May 18, 2023 Lectures

    One of the Roman Coronagraph’s critical enabling technologies is its deformable mirror(s). There are two deformable mirrors on Roman, allowing the coronagraph active control over the wavefront error...

  7. Measuring the Masses of Exoplanets and Compact Objects with the Roman Galactic Bulge Time Domain Survey

    April 20, 2023 Lectures

    The Roman Galactic Bulge Time Domain Survey (GBTDS) will detect more than 30,000 gravitational microlensing events across six observing seasons. It is expected that over 1,000 exoplanets, a few hundred...

  8. Spectral Characterization of the Roman Space Telescope Grism and Prism Slitless Spectrometers

    February 16, 2023 Lectures

    The RST Grism and Prism assemblies will provide the Wide-Field Instrument (WFI) with the ability to perform slitless, multi-object spectroscopy across the complete field of view. These optical elements...

  9. Uncovering the Galactic Black Hole Population with Gravitational Microlensing

    January 19, 2023 Lectures

    There are expected to be 100 million black holes (BHs) in the Milky Way, although until recently mass measurements existed for only two dozen or so in X-ray binary systems. However, a substantial fraction...

  10. The Keck Wide-Field Imager: Optical Partner to Roman

    November 17, 2022 Lectures

    The Keck Wide-Field Imager (KWFI) is a 1 degree diameter field of view imager for the Keck telescopes that will be the most powerful wide-field optical imager on Earth or in space for the foreseeable future....

  11. Promises and Challenges of the Roman Microlensing Survey

    October 20, 2022 Lectures

    The Roman microlensing survey is expected to detect thousands of cold planets and will revolutionize our understanding of the exoplanet demographics, as well as planet formation mechanisms. I will present...

  12. Mechanical and Thermal Design of the Coronagraph Instrument

    September 15, 2022 Lectures

    The Coronagraph Instrument is one of two payloads onboard the Roman Space Telescope, and is planned as a technology demonstration of space coronagraph technology for future Exo-Planet missions. In order...

  13. Alignment, Metrology Techniques and Testing of the Roman Space Telescope WFI Grism

    August 18, 2022 Lectures

    Dr. Margaret Dominguez has worked at NASA for over 12 years. She is currently working on the Roman Space Telescope, which will seek to study galaxies and dark energy. The WFI Grism, a slitless spectrograph...

  14. Paving the Way for Roman with Theory and Simulations – An Early Assessment for Future Wide-field, High-z Surveys

    July 21, 2022 Lectures

    NASA's next flagship observatory, the Roman Space Telescope, is expected to be launched in the late-2020s and will help us see wider into the high-redshift Universe. In order to maximize its scientific...

  15. Towards Precision Measurements of Dark Matter

    May 19, 2022 Lectures

    For more than a century now, our inference of the mass distributions (including dark matter) in galaxies have been based on modeling the positions and velocities of stars, i.e., using kinematic analyses,...
