Ionization yield measurement in a germanium CDMSlite detector using photo-neutron sources

Kavli Affiliate: Paul Brink | Summary:Two photo-neutron sources, $^88$Y$^9$Be and $^124$Sb$^9$Be, have been used to investigate the ionization yield of nuclear recoils in the CDMSlite germanium detectors by the SuperCDMS collaboration. This work evaluates the yield for nuclear recoil energies between 1 keV and 7 keV at a temperature of $sim$ 50 mK. We use […]

Strong spiral arms drive secular growth of pseudo bulges in disk galaxies

Kavli Affiliate: Jing Wang | First 5 Authors: Si-Yue Yu, Dewang Xu, Luis C. Ho, Jing Wang, Wei-Bo Kao | Summary: Spiral-driven instabilities may drive gas inflow to enhance central star formation in disk galaxies. We investigate this hypothesis using the Sloan Digital Sky Survey (SDSS) in a sample of 2779 nearby unbarred star-forming main-sequence […]
