The Luminosity Function of Ultra-Faint Trans-Neptunian Objects Detected by JWST
Marielle R. Eduardo, Anastasia N. Morgan, Wesley C. Fraser +8
We present a definitive discovery of 27 trans-Neptunian objects (TNOs) using the Near-Infrared Camera (NIRCam) aboard the James Webb Space Telescope (JWST). By employing a shift-an…
Combined JWST and HST Deep Imaging to Characterize the Smallest Known Trans-Neptunian Objects
Anastasia N. Morgan, Marielle R. Eduardo, David E. Trilling +9
We present optical-near-infrared (NIR) color measurements for small ( km) Trans-Neptunian Objects (TNOs) using coordinated and nearly simultaneous observations from the Ja…
Precision Neutron Skins of Pb and Ca from Parity-Violating Electron Scattering
PREX Collaboration, D. Adhikari, H. Albataineh +100
We have measured the parity-violating elastic electron scattering asymmetry in the PREX and CREX experiments on Pb and Ca respectively; these are both doubly-mag…
Atmospheric Reconnaissance of TRAPPIST-1 f with JWST NIRISS SOSS: No Evidence for the Transit Light Source Effect
Olivia Lim, René Doyon, Ryan J. MacDonald +25
In just over three years of operation, JWST has observed all seven planets of the TRAPPIST-1 system. The two innermost planets were found to have little to no atmosphere, barring t…
96 kHz on-sky imaging on an adaptive optics system with a single-photon avalanche diode
Theodore A. Grosson, Maaike A. M. van Kooten, Kathryn Jackson +2
Astronomical observations requiring extremely high angular resolution necessitate advanced adaptive optics (AO) systems to overcome blurring caused by the atmosphere. In addition t…
Exploring the trade-space of distributed aperture telescopes for faint-object spectroscopy
Theodore A. Grosson, Deborah M. Lokhorst, Alan W. McConnachie
Scientific programs targeting the faintest objects push modern telescopes to increasingly large sizes, high costs and complex designs. Obtaining spectra of low surface brightness g…
