Self-imaging silicon Raman amplifier
Varun Raghunathan, Hagen Renner, Robert R. Rice +1
We propose a new type of waveguide optical amplifier. The device consists of collinearly propagating pump and amplified Stokes beams with periodic imaging of the Stokes beam due to…
Brackett Lines from the Super Star Cluster Nebulae in He 2-10
Alaina L. Henry, Jean L. Turner, Sara C. Beck +3
We present high spectral resolution (v~12-16 km/s) Brackett line spectroscopy of the blue compact dwarf galaxy Henize 2-10 made with NIRSPEC on the Keck Telescope. The spatial reso…
Subarcsecond-Resolution Radio Maps of Nearby Spiral Galaxies
Chao-Wei Tsai, Jean L. Turner, Sara C. Beck +4
We report subarcsecond-resolution VLA imaging of four nearby spiral galaxies: IC 342, Maffei II, NGC 2903, and NGC 6946. In each galaxy, compact radio continuum sources are identif…
High Resolution Radio Maps of Four Nearby Spiral Galaxies
Chao-Wei Tsai, Jean L. Turner, Sara C. Beck +4
We report subarcsecond-resolution VLA imaging of the centers of four nearby spiral galaxies: IC 342, Maffei II, NGC 2903, and NGC 6946. In each galaxy, 7 - 12 compact radio continu…
State Transitions and the Continuum Limit for a 2D Interacting, Self-Propelled Particle System
Yao-li Chuang, Maria R. D'Orsogna, Daniel Marthaler +2
We study a class of swarming problems wherein particles evolve dynamically via pairwise interaction potentials and a velocity selection mechanism. We find that the swarming system…
The James Webb Space Telescope
Jonathan P. Gardner, John C. Mather, Mark Clampin +20
The James Webb Space Telescope (JWST) is a large (6.6m), cold (50K), infrared-optimized space observatory that will be launched early in the next decade. The observatory will have…
