Defect dynamics in growing bacterial colonies

Kavli Affiliate: Sander J. Tans | First 5 Authors: Rachel Los, Duco van Holthe tot Echten, Gerhard Nordemann, Martijn Wehrens, Sander J. Tans | Summary: Colonies of rod-shaped bacteria constitute a system of colloidal active matter with nematic properties. As a single initial bacterium multiplies through repeated divisions, the resulting colony quickly loses long-range orientational […]

Dark Energy Survey Identification of A Low-Mass Active Galactic Nucleus at Redshift 0.823 from Optical Variability

Kavli Affiliate: Aaron Roodman | First 5 Authors: Hengxiao Guo, Colin J. Burke, Xin Liu, Kedar A. Phadke, Kaiwen Zhang | Summary: We report the identification of a low-mass AGN, DES J0218$-$0430, in a redshift $z = 0.823$ galaxy in the Dark Energy Survey (DES) Supernova field. We select DES J0218$-$0430 as an AGN candidate […]

The TESS-Keck Survey I: A Warm Sub-Saturn-mass Planet and a Caution about Stray Light in TESS Cameras

Kavli Affiliate: Robert F. Goeke | First 5 Authors: Paul A. Dalba, Arvind F. Gupta, Joseph E. Rodriguez, Diana Dragomir, Chelsea X. Huang | Summary: We report the detection of a Saturn-size exoplanet orbiting HD 332231 (TOI 1456) in light curves from the Transiting Exoplanet Survey Satellite (TESS). HD 332231, an F8 dwarf star with […]
