The Origin and Motion of PSR J0538+2817 in S147 (2006)

Romani, Roger W., Brisken, Walter F., Chatterjee, Shami, Kramer, Michael

We report on VLBA astrometry and CXO imaging of PSR J0538+2817 in the supernova remnant S147. We measure a parallax distance of $1.47^{+0.42}_{-0.27}$kpc along with a high-precision proper motion,...

A Very High Spectral Resolution Study of Ground-State OH Masers in W3(OH) (2006)

Fish, Vincent L., Brisken, Walter F., Sjouwerman, LorĂ¡nt O.

We present VLBA observations of the ground-state hydroxyl masers in W3(OH) at 0.02 km s-1 spectral resolution. Over 250 masers are detected, including 56 Zeeman pairs. Lineshapes are predominantly...

Overview of the coordinated ground-based observations of Titan during the Huygens mission (2006)

Witasse, Olivier, Lebreton, Jean-Pierre, Bird, Michael K., Dutta-Roy, Robindro, Folkner, William M., Preston, Robert A., ...

Coordinated ground-based observations of Titan were performed around or during the Huygens atmospheric probe mission at Titan on 14 January 2005, connecting the momentary in situ observations by the...

Pulsar PSR B0656+14, the Monogem Ring, and the Origin of the `Knee' in the Primary Cosmic Ray Spectrum (2003)

Thorsett, S. E., Benjamin, R. A., Brisken, Walter F., Golden, A., Goss, W. M.

The Monogem ring is a bright, diffuse, 25-degree-diameter supernova remnant easily visible in soft X-ray images of the sky. Projected within the ring is a young radio pulsar, PSR B0656+14. An...

VLBA Measurement of Nine Pulsar Parallaxes (2002)

Brisken, Walter F., Benson, John M., Goss, W. M., Thorsett, S. E.

We determined the distances to nine pulsars by parallax measurements using the NRAO Very Long Baseline Array, doubling the number of pulsars with accurate distance measurements. Broadband phase...

Measurement of the Parallax of PSR B0950+08 Using the VLBA (2000)

Brisken, Walter F., Benson, John M., Beasley, A. J., Fomalont, Edward B., Goss, W. M., Thorsett, S. E.

A new technique has been developed to remove the ionosphere's distorting effects from low frequency VLBI data. By fitting dispersive and non-dispersive components to the phases of multi-frequency...
