Kavli Affiliate: Robert Byer | Summary:We demonstrate a compact technique to compress electron pulses to attosecond length, while keeping the energy spread reasonably small. The technique is based on Dielectric Laser Acceleration (DLA) in nanophotonic silicon structures. Unlike previous ballistic optical microbunching demonstrations, we use a modulator-demodulator scheme to compress phase space in the time […]

Kavli Affiliate: Paul Brink | Summary:We present limits on spin-independent dark matter-nucleon interactions using a $10.6$ $mathrmg$ Si athermal phonon detector with a baseline energy resolution of $σ_E=3.86 pm 0.04$ $(mathrmstat.)^+0.19_-0.00$ $(mathrmsyst.)$ $mathrmeV$. This exclusion analysis sets the most stringent dark matter-nucleon scattering cross-section limits achieved by a cryogenic detector for dark matter particle masses […]

Kavli Affiliate: James Chiang | First 5 Authors: James Chiang, , , , | Summary: Smart contracting protocols promise to regulate the transfer of cryptocurrency amongst participants in a trustless manner. A safe smart contract implementation should ensure that each participant can always append a contract transaction to the blockchain in order move the contract […]

Ade, Simone Aiola, David Alonso —- Summary: We present the temperature and polarization angular power spectra of the CMB measured by the Atacama Cosmology Telescope (ACT) from 5400 deg$^2$ […]

Kavli Affiliate: Shawn Henderson | First 5 Authors: Simone Aiola, Erminia Calabrese, Loïc Maurin, Sigurd Naess, Benjamin L. Schmitt | Summary: We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013-2016 at 98 and 150 GHz. The maps cover more than […]

Kavli Affiliate: Hsiao-Mei (Sherry) Cho |Summary:We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013-2016 at 98 and 150 GHz. The maps cover more than 17,000 deg$^2$, the deepest 600 deg$^2$ with noise levels below 10 $μ$K-arcmin. We use the power […]

Kavli Affiliate: Risa Wechsler | First 5 Authors: Catherine E. Fielder, Yao-Yuan Mao, Andrew R. Zentner, Jeffrey A. Newman, Hao-Yi Wu | Summary: Cold dark matter haloes consist of a relatively smooth dark matter component as well as a system of bound subhaloes. It is the prevailing practice to include all halo mass, including mass […]

Kavli Affiliate: J. Todd Hoeksema | Summary:The Coronal Global Evolutionary Model (CGEM) provides data-driven simulations of the magnetic field in the solar corona to better understand the build-up of magnetic energy that leads to eruptive events. The CGEM project has developed six capabilities. CGEM modules (1) prepare time series of full-disk vector magnetic field observations […]

Kavli Affiliate: Bruce A. Macintosh | First 5 Authors: Pauline Arriaga, Michael P. Fitzgerald, Gaspard Duchêne, Paul Kalas, Maxwell A. Millar-Blanchaer | Summary: HR4796A hosts a well-studied debris disk with a long history due to its high fractional luminosity and favorable inclination lending itself well to both unresolved and resolved observations. We present new J- […]

Kavli Affiliate: C. M. Ignarra | First 5 Authors: D. S. Akerib, C. W. Akerlof, D. Yu. Akimov, A. Alquahtani, S. K. Alsum | Summary: LUX-ZEPLIN (LZ) is a second-generation direct dark matter experiment with spin-independent WIMP-nucleon scattering sensitivity above $1.4 times 10^{-48}$ cm$^{2}$ for a WIMP mass of 40 GeV/c$^{2}$ and a 1000 d […]
