Sr3CrN3: a new electride with partially filled d-shells

Kavli Affiliate: Jin Suntivich | First 5 Authors: Padtaraporn Chanhom, Kevin E. Fritz, Lee Burton, Jan Kloppenburg, Yaroslav Filinchuk | Summary: Electrides are ionic crystals in which the electrons prefer to occupy free space, serving as anions. Because the electrons prefer to be in the pockets, channels, or layers to the atomic orbitals around the […]

Evidence for the Cross-correlation between Cosmic Microwave Background Polarization Lensing from POLARBEAR and Cosmic Shear from Subaru Hyper Suprime-Cam

Kavli Affiliate: Hiroaki Aihara | First 5 Authors: Toshiya Namikawa, Yuji Chinone, Hironao Miyatake, Masamune Oguri, Ryuichi Takahashi | Summary: We present the first measurement of cross-correlation between the lensing potential, reconstructed from cosmic microwave background (CMB) {it polarization} data, and the cosmic shear field from galaxy shapes. This measurement is made using data from […]

Astro2020 Science White Paper: Black Holes Across Cosmic Time

Kavli Affiliate: Luis Ho | First 5 Authors: Kayhan G├╝ltekin, Aaron Barth, Karl Gebhardt, Jenny Greene, Luis Ho | Summary: Supermassive black holes are located at the center of most, if not all, massive galaxies. They follow close correlations with global properties of their host galaxies (scaling relations), and are thought to play a crucial […]
