The LUX-ZEPLIN (LZ) radioactivity and cleanliness control programs

Kavli Affiliate: T. A. Shutt | 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 exposure. LZ achieves this sensitivity through a combination of a large 5.6 t fiducial volume, active inner and outer […]

Constraints on low-mass, relic dark matter candidates from a surface-operated SuperCDMS single-charge sensitive detector

Kavli Affiliate: Paul Brink | Summary:This article presents an analysis and the resulting limits on light dark matter inelastically scattering off of electrons, and on dark photon and axion-like particle absorption, using a second-generation SuperCDMS high-voltage eV-resolution detector. The 0.93 gram Si detector achieved a 3 eV phonon energy resolution; for a detector bias of […]

Orbital Modulation of Gamma Rays from PSR~J2339$-$0533

Kavli Affiliate: Roger W. Romani | First 5 Authors: Hongjun An, Roger W. Romani, Matthew Kerr, , | Summary: We report on orbital modulation of the 100-600 MeV gamma-ray emission of the $P_{rm B}=4.6$ hr millisecond pulsar binary PSR J2339$-$0533 using 11 yr of Fermi Large Area Telescope data. The modulation has high significance (chance […]

Muons in supernovae: implications for the axion-muon coupling

Kavli Affiliate: Peter W. Graham | First 5 Authors: Robert Bollig, William DeRocco, Peter W. Graham, Hans-Thomas Janka, | Summary: The high temperature and electron degeneracy attained during a supernova allow for the formation of a large muon abundance within the core of the resulting proto-neutron star. If new pseudoscalar degrees of freedom have large […]

Survey of Gravitationally-lensed Objects in HSC Imaging (SuGOHI). VI. Crowdsourced lens finding with Space Warps

Kavli Affiliate: Philip J. Marshall | First 5 Authors: Alessandro Sonnenfeld, Aprajita Verma, Anupreeta More, Elisabeth Baeten, Christine Macmillan | Summary: Strong lenses are extremely useful probes of the distribution of matter on galaxy and cluster scales at cosmological distances, but are rare and difficult to find. The number of currently known lenses is on […]

Towards windproofing LIGO: Reducing the effect of wind-driven floor tilt by using rotation sensors in active seismic isolation

Kavli Affiliate: Brian Lantz | First 5 Authors: Michael P. Ross, Krishna Venkateswara, Conor Mow-Lowry, Sam Cooper, Jim Warner | Summary: Modern gravitational-wave observatories require robust low-frequency active seismic isolation in order to keep the interferometer at its ideal operating conditions. Seismometers are used to measure both the motion of the ground and isolated platform. […]
