Mid-infrared Variability of Low-redshift Active Galactic Nuclei : Constraints on a Hot Dust Component with a Variable Covering Factor

Kavli Affiliate: Luis C. Ho | First 5 Authors: Suyeon Son, Minjin Kim, Luis C. Ho, , | Summary: We utilize mid-infrared multi-epoch data from Wide-field Infrared Survey Explorer (WISE) over a $sim10$-year period in W1 (3.4$mu$m) and W2 (4.6$mu$m) bands to investigate the structure of dusty torus in low-redshift ($0.15<zle 0.4$) active galactic nuclei […]

Improved tracking of particles with highly correlated motion

Kavli Affiliate: David A. Weitz | First 5 Authors: Ella M. King, Zizhao Wang, David A. Weitz, Frans Spaepen, Michael P. Brenner | Summary: Despite significant advances in particle imaging technologies over the past two decades, few advances have been made in particle tracking, i.e. linking individual particle positions across time series data. The state-of-the-art […]

Constraining galaxy overdensities around three z~6.5 quasars with ALMA and MUSE

Kavli Affiliate: Ran Wang | First 5 Authors: Romain A. Meyer, Roberto Decarli, Fabian Walter, Qiong Li, Ran Wang | Summary: We quantify galaxy overdensities around three high-redshift quasars with known [CII] 158um companions: PJ231-20 (z=6.59), PJ308-21 (z=6.24) and J0305-3150 (z=6.61). Recent SCUBA2 imaging revealed the presence of 17 submillimeter galaxies (SMG) with sky separations […]

Van der Waals pi Josephson junctions

Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Helmuth Berger, Kenji Watanabe, Takashi Taniguchi, Laszlo Forro | Summary: Proximity-induced superconductivity in a ferromagnet can induce Cooper pairs with a finite center-of-mass momentum. The resultant spatially modulated superconducting order parameter is able to stabilize Josephson junctions (JJs) with pi phase difference in superconductor-ferromagnet heterostructures […]
