The Impact of the MAST Data Archive
Richard A. Shaw, Jenny L. Novacescu, Sarah Weissman +31
The Barbara A. Mikulski Archive for Space Telescopes (MAST) hosts science-ready data products from over twenty NASA missions, plus community-contributed data collections, and other…
Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
A Classic Nonlinearity Correction Algorithm for Detectors Read Out Up-The-Ramp
Timothy D. Brandt
We derive an algorithm for computing a classic nonlinearity correction -- applicable to constant and uniform illumination -- in the presence of read noise and photon noise. The alg…
Computing the Electronic Gain for Detectors Read Out Up-The-Ramp
Timothy D. Brandt
The electronic gain -- the conversion between photoelectrons on a pixel and the digital number recorded to disk -- gives physical units to an astronomical image and sets the relati…
yieldplotlib: A unified library for exoplanet yield code visualizations
Corey Spohn, Sarah Steiger, Alex R. Howe
NASA's next flagship observatory, the Habitable Worlds Observatory (HWO), aims to detect and charaterize ~25 habitable zone planets. The total number of habitable zone planets dete…
Push-broom Mapping of Galaxies and Supernova Remnants with the SPRITE CubeSat
Elena Carlson, Brian Fleming, Yi Hang Valerie Wong +12
Supernovae (SNe) enrich and energize the surrounding interstellar medium (ISM) and are a key mechanism in the galaxy feedback cycle. The heating of the ISM by supernova shocks, and…
