Searching for Axion-Like Particles from Core-Collapse Supernovae with Fermi LAT’s Low Energy Technique

Posted by klaurent Stanford

Kavli Affiliate: Nicola Omodei | First 5 Authors: Milena Crnogorčević, Regina Caputo, Manuel Meyer, Nicola Omodei, Michael Gustafsson | Summary: Light axion-like particles (ALPs) are expected to be abundantly produced in core-collapse supernovae (CCSNe), resulting in a $sim$10-second long burst of ALPs. These particles subsequently undergo conversion into gamma-rays in external magnetic fields to produce […]

Canonical retinotopic shifts under an inverse force field explain predictive remapping

Posted by klaurent Yale

Kavli Affiliate: Michael Keiser | Authors: Laura M Gunsalus, Michael J. Keiser and Katherine S Pollard | Summary: ABSTRACT Predictive remapping — the ability of cells in retinotopic brain areas to transiently exhibit spatio-temporal retinotopic shifts beyond the spatial extent of their classical receptive fields — has been proposed as a primary mechanism that stabilizes […]

Discretization of Annular-Ring Diffraction Pattern for Large-Scale Photonics Beamforming

Posted by Caltech

Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Artsroun Darbinian, Ali Hajimiri, | Summary: A solid-state active beamformer based on the annular-ring diffraction pattern is proposed for an integrated photonic platform. Such a circularly symmetric annular-ring aperture achieves radiating element limited FOV. Furthermore, it is demonstrated that a multi-annular-ring aperture with […]

Electrical spectroscopy of the spin-wave dispersion and bistability in gallium-doped yttrium iron garnet

Posted by klaurent Delft

Kavli Affiliate: Toeno Van Der Sar | First 5 Authors: Joris J. Carmiggelt, Olaf C. Dreijer, Carsten Dubs, Oleksii Surzhenko, Toeno van der Sar | Summary: Yttrium iron garnet (YIG) is a magnetic insulator with record-low damping, allowing spin-wave transport over macroscopic distances. Doping YIG with gallium ions greatly reduces the demagnetizing field and introduces […]

Evaluating and Enhancing Candidate Clocking Systems for CHIME/FRB VLBI Outriggers

Posted by klaurent MIT

Kavli Affiliate: Kiyoshi Masui | First 5 Authors: Savannah Cary, Juan Mena-Parra, Calvin Leung, Kiyoshi Masui, J. F. Kaczmarek | Summary: As the Canadian Hydrogen Intensity Mapping Experiment (CHIME) has become the leading instrument for detecting Fast Radio Bursts (FRBs), CHIME/FRB Outriggers will use very-long-baseline interferometry (VLBI) to localize FRBs with milliarcsecond precision. The CHIME […]

Directional Detection of Light Dark Matter in Superconductors

Posted by klaurent Stanford

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Eric David Kramer, Noah Kurinsky, Benjamin V. Lehmann, | Summary: Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for directional detection of dark matter in […]

The Atacama Cosmology Telescope: Constraints on Pre-Recombination Early Dark Energy

Posted by klaurent Tokyo

Kavli Affiliate: David N. Spergel | First 5 Authors: J. Colin Hill, Erminia Calabrese, Simone Aiola, Nicholas Battaglia, Boris Bolliet | Summary: The early dark energy (EDE) scenario aims to increase the value of the Hubble constant ($H_0$) inferred from cosmic microwave background (CMB) data over that found in $Lambda$CDM, via the introduction of a […]
