Near-Infrared, Kilosecond Variability of the Wisps and Jet in the Crab Pulsar Wind Nebula
A. Melatos, D. Scheltus, M. T. Whiting +6
We present a time-lapse sequence of 20 near-infrared (J- and K'-band) snapshots of the central 20x20 arcsec of the Crab pulsar wind nebula, taken at subarcsecond resolution with th…
The Complex Wind Torus and Jets of PSR B1706-44
Roger W. Romani, C. -Y. Ng, Richard Dodson +1
We report on Chandra ACIS imaging of the pulsar wind nebula (PWN) of the young Vela-like PSR B1706-44, which shows the now common pattern of an equatorial wind and polar jets. The…
The Fall 2004 SDSS Supernova Survey
Masao Sako, Roger Romani, Josh Frieman +38
In preparation for the Supernova Survey of the Sloan Digital Sky Survey (SDSS) II, a proposed 3-year extension to the SDSS, we have conducted an early engineering and science run d…
Two Pulsar Wind Nebulae: Chandra/XMM-Newton Imaging of GeV J1417-6100
C. -Y. Ng, Mallory S. E. Roberts, Roger W. Romani
We report on Chandra ACIS and XMM-Newton MOS/PN imaging observations of two pulsar wind nebulae (K3/PSR J1420-6048 and G313.3+0.1=`the rabbit') associated with the Galactic unident…
A Search for Radio Emission from the Young 16-ms X-ray Pulsar PSR J0537-6910
F. Crawford, M. McLaughlin, S. Johnston +2
PSR J0537-6910 is a young, energetic, rotation-powered X-ray pulsar with a spin period of 16 ms located in the Large Magellanic Cloud. We have searched for previously undetected ra…
The Vela Pulsar in the Ultraviolet
Roger W. Romani, Oleg Kargaltsev, George G. Pavlov
We describe time-tagged observations of the Vela pulsar (PSR B0833-45) with the HST STIS MAMA-UV detectors. Using an optimal extraction technique, we obtain a NUV light curve and c…
A Northern Survey of Gamma-Ray Blazar Candidates
David Sowards-Emmerd, Roger W. Romani, Peter F. Michelson +2
In preparation for GLAST, we have compiled a sample of blazar candidates to increase the pool of well studied AGN from which GLAST counterparts will be drawn. Sources were selected…
Ultraviolet, X-ray, and Optical Radiation from the Geminga Pulsar
O. Y. Kargaltsev, G. G. Pavlov, V. E. Zavlin +1
We observed the gamma-ray pulsar Geminga with the HST STIS/MAMA detectors to measure the Geminga's UV spectrum and pulsations. The slope of the far-UV (FUV) spectrum is close to th…
