Calibrating Galaxy Formation Models for the Roman Era
May 21, 2026 LecturesThe Nancy Grace Roman Space Telescope will soon conduct one of the largest spectroscopic galaxy surveys ever attempted, mapping tens of millions of galaxies to study cosmic acceleration and galaxy evolution. ...
-
Characterizing the Brighter-Fatter Effect and Its Impact on PSF Size in a Roman Detector
April 16, 2026 LecturesMany of Roman's key science objectives require precise point spread function (PSF) calibration. In particular, weak gravitational lensing studies depend on measurements of very small distortions in ...
-
Characterizing the Galactic Black Hole Population with Roman Astrometry
February 19, 2026 LecturesRoman's Galactic Bulge Time Domain Survey (GBTDS) will be an astrometry machine. The GBTDS will produce precise astrometry at an unprecedented temporal sampling for a large number of sources that both ...
-
Photometric Calibration Uncertainties in Stage IV Supernova Cosmology
November 20, 2025 LecturesUpcoming supernova surveys, such as the Nancy Grace Roman Space Telescope (Roman) and the Vera Rubin Observatory’s LSST, are expected to discover over a million supernovae, vastly increasing current ...
-
Optimizing Roman Photometric Redshifts for HLIS
September 25, 2025 LecturesPhoto-z’s are crucial for the main cosmology, galaxy evolution, and transient science drivers of Roman. The transformative nature of the Roman dataset presents both new challenges but also new opportunities ...
-
The Roman Galactic Bulge Time Domain Survey
August 21, 2025 LecturesRoman's wide-field infrared camera, with a field of view 100 times larger than the Hubble Space Telescope, will provide unique time-domain astronomy in crowded fields that have been inaccessible with ...
-
Accreting Neutron Stars and Black Holes in our Galaxy through the Lens of Roman
July 31, 2025 LecturesOver the past decade, our understanding of the population and behavior of compact objects has shifted significantly, thanks to a multitude of novel facilities, from gravitational wave observatories, astrometry ...
-
Chromatic Effects on the PSF and Shear Measurement for the Roman Space Telescope
May 15, 2025 LecturesWeak gravitational lensing is a key cosmological probe that requires precise measurement of galaxy images to infer shape distortions, or shear, and thereby constrain cosmology. Accurate estimation of the ...
-
Kinematic Lensing with the Roman Space Telescope
September 19, 2024 LecturesThe Nancy Grace Roman Space will address science cases ranging from exoplanets to galaxy evolution to fundamental physics. The High Latitude Survey (HLS) component is designed to constrain dark energy ...
-
Modeling and Performance Analysis of iEFC for the Roman/CGI SPC Mode
August 15, 2024 LecturesHigh-order wavefront sensing and control (HOWFSC) is key to creating a dark hole region within the coronagraphic image plane where high contrasts are achieved. The Roman Coronagraph is expected to perform ...
-
Accounting for Spontaneous Charge Production in the EMCCD Gain Register
May 16, 2024 LecturesAn electron-multiplying charge-coupled device (EMCCD) is often used for taking images with space telescopes and other devices. Photons hit the pixels and photo-electrons are created, and these are multiplied ...
-
Stellar Spin and Spots with Roman
April 18, 2024 LecturesRotation and star spots reveal insights to the magnetic lives of stars. Stars less massive than the Sun experience magnetic braking, slowing their rotation as they age. This spin-down should allow us to ...
-
Obscured AGN: Hiding High Growth at the Cosmic Noon
March 21, 2024 LecturesMost bulge-dominated galaxies host black holes with masses that tightly correlate with the masses of their bulges. This correlation suggests that black holes and their host galaxies may co-evolve or mutually ...
-
Astronomy Re-envisioned: Investigating the Physics of Galaxy Evolution with Machine Learning
February 15, 2024 LecturesAstronomical 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 ...
-
Simulation of High-contrast Polarimetric Observations of Debris Disks with the Roman Coronagraph Instrument
January 18, 2024 LecturesThe 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 ...
