The HST See Change Program: I. Survey Design, Pipeline, and Supernova Discoveries
Kavli Affiliate: Risa Wechsler | First 5 Authors: Brian Hayden, David Rubin, Kyle Boone, Greg Aldering, Jakob Nordin | Summary: The See Change survey was designed to make $z>1$ cosmological measurements by efficiently discovering high-redshift Type Ia supernovae (SNe Ia) and improving cluster mass measurements through weak lensing. This survey observed twelve galaxy clusters with […]

Search for anisotropic gravitational-wave backgrounds using data from Advanced LIGO and Advanced Virgo’s first three observing runs
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration, R. Abbott, T. D. Abbott | Summary: We report results from searches for anisotropic stochastic gravitational-wave backgrounds using data from the first three observing runs of the Advanced LIGO and Advanced Virgo detectors. For the first time, […]

Water on Hot Rocky Exoplanets
Kavli Affiliate: Laura Schaefer | First 5 Authors: Edwin S. Kite, Laura Schaefer, , , | Summary: Data suggest that most rocky exoplanets with orbital period $p$ $<$ 100 d ("hot" rocky exoplanets) formed as gas-rich sub-Neptunes that subsequently lost most of their envelopes, but whether these rocky exoplanets still have atmospheres is unknown. We […]

Characterization of Skipper CCDs for Cosmological Applications
Kavli Affiliate: Noah Kurinsky | First 5 Authors: Alex Drlica-Wagner, Edgar Marrufo Villalpando, Judah O’Neil, Juan Estrada, Stephen Holland | Summary: We characterize the response of a novel 250 $mu$m thick, fully-depleted Skipper Charged-Coupled Device (CCD) to visible/near-infrared light with a focus on potential applications for astronomical observations. We achieve stable, single-electron resolution with readout […]

Effects of overlapping sources on cosmic shear estimation: Statistical sensitivity and pixel-noise bias
Kavli Affiliate: Patricia R. Burchat | First 5 Authors: Javier Sanchez, Ismael Mendoza, David P. Kirkby, Patricia R. Burchat, | Summary: In Stage-IV imaging surveys, a significant amount of the cosmologically useful information is due to sources whose images overlap with those of other sources on the sky. The cosmic shear signal is primarily encoded […]

The Nancy Grace Roman Space Telescope Coronagraph Instrument (CGI) Technology Demonstration
Kavli Affiliate: Bruce Macintosh | First 5 Authors: N. Jeremy Kasdin, Vanessa P. Bailey, Bertrand Mennesson, Robert T. Zellem, Marie Ygouf | Summary: The Coronagraph Instrument (CGI) on the Nancy Grace Roman Space Telescope will demonstrate the high-contrast technology necessary for visible-light exoplanet imaging and spectroscopy from space via direct imaging of Jupiter-size planets and […]

GRB 191016A: A Long Gamma-Ray Burst Detected by TESS
Kavli Affiliate: Nicola Omodei | First 5 Authors: Krista Lynne Smith, Ryan Ridden-Harper, Michael Fausnaugh, Tansu Daylan, Nicola Omodei | Summary: The TESS exoplanet-hunting mission detected the rising and decaying optical afterglow of GRB 191016A, a long Gamma-Ray Burst (GRB) detected by Swift-BAT but without prompt XRT or UVOT follow-up due to proximity to the […]

Effects of turbulence in the Circumnuclear Disk
Kavli Affiliate: R. Morris | First 5 Authors: Cuc K. Dinh, Jesus M. Salas, Mark R. Morris, Smadar Naoz, | Summary: A Circumnuclear Disk (CND) of molecular gas occupies the central few parsecs of the Galactic Center. It is likely subject to turbulent disruptions from violent events in its surrounding environment, but the effect of […]
