An HST/WFC3-UVIS View of the Starburst in the Cool Core of the Phoenix Cluster

Posted by Chicago

Kavli Affiliate: Bradford Benson | First 5 Authors: Michael McDonald, Bradford Benson, Sylvain Veilleux, Marshall W. Bautz, Christian L. Reichardt | Summary: We present Hubble Space Telescope Wide Field Camera 3 observations of the core of the Phoenix Cluster SPT-CLJ2344-4243 in five broadband filters spanning rest-frame 1000–5500A. These observations reveal complex, filamentary blue emission, extending […]

Higher-order defect mode laser in an optically thick photonic crystal slab

Posted by dbos Caltech

Kavli Affiliate: Axel Scherer | First 5 Authors: Se-Heon Kim, Jingqing Huang, Axel Scherer, , | Summary: The use of an optically thick slab may provide versatile solutions for the realization of a current injection type laser using photonic crystals. Here, we show that a transversely higher-order defect mode can be designed to be confined […]

MKID development for SuperSpec: an on-chip, mm-wave, filter-bank spectrometer

Posted by Chicago

Kavli Affiliate: Erik Shirokoff | First 5 Authors: Erik Shirokoff, Peter S. Barry, Charles M. Bradford, Goutam Chattopadhyay, Peter Day | Summary: SuperSpec is an ultra-compact spectrometer-on-a-chip for millimeter and submillimeter wavelength astronomy. Its very small size, wide spectral bandwidth, and highly multiplexed readout will enable construction of powerful multibeam spectrometers for high-redshift observations. The […]
