SPT-3G D1: CMB temperature and polarization power spectra and cosmology from 2019 and 2020 observations of the SPT-3G Main field

Posted by klaurent Stanford

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: We present measurements of the temperature and E-mode polarization angular power spectra of the cosmic microwave background (CMB) from observations of 4% of the sky with SPT-3G, the current camera on the South Pole Telescope (SPT). The maps used in […]

The Singapore Consensus on Global AI Safety Research Priorities

Posted by klaurent MIT

Kavli Affiliate: Max Tegmark | First 5 Authors: Yoshua Bengio, Yoshua Bengio, , , | Summary: Rapidly improving AI capabilities and autonomy hold significant promise of transformation, but are also driving vigorous debate on how to ensure that AI is safe, i.e., trustworthy, reliable, and secure. Building a trusted ecosystem is therefore essential — it […]

An iterative CMB lensing estimator minimizing instrumental noise bias

Posted by klaurent Cambridge

Kavli Affiliate: Anthony Challinor | First 5 Authors: Louis Legrand, Louis Legrand, , , | Summary: Noise maps from CMB experiments are generally statistically anisotropic, due to scanning strategies, atmospheric conditions, or instrumental effects. Any mis-modeling of this complex noise can bias the reconstruction of the lensing potential and the measurement of the lensing power […]

Giant Outer Transiting Exoplanet Mass (GOT ‘EM) Survey. VI: Confirmation of a Long-Period Giant Planet Discovered with a Single TESS Transit

Posted by klaurent MIT

Kavli Affiliate: Sara Seager | First 5 Authors: , , , , | Summary: We report the discovery and confirmation of TOI-4465 b, a $1.25^+0.08_-0.07~R_J$, $5.89pm0.26~M_J$ giant planet orbiting a G dwarf star at $dsimeq$ 122 pc. The planet was detected as a single-transit event in data from Sector 40 of the Transiting Exoplanet Survey […]

Hundreds of TESS exoplanets might be larger than we thought

Posted by klaurent MIT

Kavli Affiliate: George Ricker | First 5 Authors: Te Han, Te Han, , , | Summary: The radius of a planet is a fundamental parameter that probes its composition and habitability. Precise radius measurements are typically derived from the fraction of starlight blocked when a planet transits its host star. The wide-field Transiting Exoplanet Survey […]

First High-Throughput Evaluation of Dark Matter Detector Materials

Posted by klaurent Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Sinéad M. Griffin, Sinéad M. Griffin, , , | Summary: We perform the first high-throughput search and evaluation of materials that can serve as excellent low-mass dark matter detectors. Using properties of close to one thousand materials from the Materials Project database, we project the sensitivity […]

Atomic layer etching of InGaAs using sequential exposures of atomic hydrogen and oxygen gas

Posted by klaurent Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Mete M. Bayrak, Mete M. Bayrak, , , | Summary: The high frequency performance and yield of III-V semiconductor devices such as InP HEMTs is negatively impacted by subsurface etch damage and non-uniform etch depth over the wafer. Atomic layer etching (ALE) has the potential to […]

Decoherence and fidelity enhancement during shuttling of entangled spin qubits

Posted by klaurent Delft

Kavli Affiliate: Viatcheslav V. Dobrovitski | First 5 Authors: [#item_custom_name[1]], [#item_custom_name[2]], [#item_custom_name[3]], [#item_custom_name[4]], [#item_custom_name[5]] | Summary: Shuttling of spin qubits between different locations is a key element in many prospective semiconductor systems for quantum information processing, but the shuttled qubits should be protected from decoherence created by time- and space-dependent noises. Since the paths of […]
