A tiny galaxy has given astronomers a glimpse of a time when the first bright objects in the universe formed, ending the dark ages that followed the birth of the u...
Title: DA495 - an aging pulsar wind nebula Authors: R. Kothes, T.L. Landecker, W. Reich, S. Safi-Harb, Z. Arzoumanian We present a radio continuum study of the pulsar wind nebula (PWN) DA 495 (G65.7+1.2), including images of total intensity and linear polarization from 408 to 10550 MHz based on the...
Title: Improved Algorithms for Radar-based Reconstruction of Asteroid Shapes Author: Adam H. Greenberg, Jean-Luc Margot We describe our implementation of a global-parameter optimizer and Square Root Information Filter (SRIF) into the asteroid-modelling software SHAPE. We compare the per...
