Kavli Affiliate: Bruce Macintosh | First 5 Authors: Kyle Van Gorkom, Kyle Van Gorkom, , , | Summary: NASA’s Habitable Worlds Observatory (HWO) aims to achieve starlight suppression to the $10^-10$ level for the detection and spectral characterization of Earth-like exoplanets. Broadband ozone absorption features are key biosignatures that appear in the 200-400nm near-ultraviolet (UV) […]
Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: Y. Wan, Y. Wan, , , | Summary: Blind discoveries of millimeter-wave (mm-wave) transient events in non-targeted surveys, as opposed to follow-up or pointed observations, have only become possible in the past decade using cosmic microwave background surveys. Here we present the first results from the SPT-3G […]
Kavli Affiliate: Sven Herrmann | First 5 Authors: Govindarajan Prakash, Govindarajan Prakash, , , | Summary: Optically trapped Silica nanoparticles are a promising tool for precise sensing of gravitational or inertial forces and fundamental physics, including tests of quantum mechanics at ‘large’ mass scales. This field, called levitated optomechanics can greatly benefit from an application […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Jayke S. Nguyen, Jayke S. Nguyen, , , | Summary: Mid-IR wavelengths are of particular interest to exoplanet science due to the fact they can extend the searchable parameter space to planets that are older and/or colder. However, a significant source of uncertainty at mid-IR wavelengths on […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Jack T. Dinsmore, Jack T. Dinsmore, , , | Summary: As the Imaging X-ray Polarimetry Explorer (IXPE) measures increasingly faint sources, the need for precise polarimetry extraction becomes paramount. In addition to previously described neural-net (NN) weights, we introduce here point-spread function weights and particle background […]
Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Nathalie K. Jones, Nathalie K. Jones, , , | Summary: We present confirmation of HD 143811 AB b, a substellar companion to spectroscopic binary HD 143811 AB through direct imaging with the Gemini Planet Imager (GPI) and Keck NIRC2. HD 143811 AB was observed as a […]
Kavli Affiliate: Bruce Macintosh | First 5 Authors: Anne E. Peck, Anne E. Peck, , , | Summary: HD~143811~AB is the host star to the directly imaged planet HD~143811~AB~b, which was recently discovered using data from the Gemini Planet Imager and Keck NIRC2. A member of the Sco-Cen star-forming region with an age of $13 […]
Kavli Affiliate: Roger W. Romani | First 5 Authors: Michael Zhang, Michael Zhang, , , | Summary: A handful of enigmatic Jupiter-mass objects have been discovered orbiting pulsars. One such object, PSR J2322-2650b, uniquely resembles a hot Jupiter exoplanet due to its minimum density of 1.8 g/cm^3 and its ~1900 K equilibrium temperature. We use […]
Kavli Affiliate: D. B. Macfarlane | First 5 Authors: SuperCDMS Collaboration, SuperCDMS Collaboration, , , | Summary: We present constraints on low mass dark matter-electron scattering and absorption interactions using a SuperCDMS high-voltage eV-resolution (HVeV) detector. Data were taken underground in the NEXUS facility located at Fermilab with an overburden of 225 meters of water […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Albert Nazeeri, Albert Nazeeri, , , | Summary: Mechanical modulation of recoilless nuclear transitions allows the dynamic control of gamma-ray emission and absorption. Accessing modulation frequencies well above the nuclear linewidth enables coherent manipulation of the nuclear response. Here we demonstrate such control by coupling a film […]
