A pioneering experiment combining single-antenna and aperture-synthesis data to measure Faraday rotation with GMIMS and the CGPS
Anna Ordog, Jo-Anne C. Brown, T. L. Landecker +11
Structures in the magnetoionic medium exist across a wide range of angular sizes owing to large-scale magnetic fields coherent over the Galactic spiral arms combined with small-sca…
Faraday tomography with CHIME: the `tadpole' feature G137+7
Nasser Mohammed, Anna Ordog, Rebecca A. Booth +27
A direct consequence of Faraday rotation is that the polarized radio sky does not resemble the total intensity sky at long wavelengths. We analyze G137+7, which is undetectable in…
Revisiting Rotation Measures from the Canadian Galactic Plane Survey: the Magnetic Field in the Disk of the Outer Galaxy
C. L. Van Eck, J. C. Brown, A. Ordog +9
Faraday rotation provides a valuable tracer of magnetic fields in the interstellar medium; catalogs of Faraday rotation measures provide key observations for studies of the Galacti…
A 1420 MHz Catalog of Compact Sources in the Northern Galactic Plane
A. R. Taylor, D. A. Leahy, T. Wenwu +5
We present a catalog of compact sources of radio emission at 1420 MHz in the northern Galactic plane from the Canadian Galactic Plane Survey. The catalog contains 72,787 compact so…
The Detailed Science Case for the Maunakea Spectroscopic Explorer: the Composition and Dynamics of the Faint Universe
Alan McConnachie, Carine Babusiaux, Michael Balogh +173
MSE is an 11.25m aperture observatory with a 1.5 square degree field of view that will be fully dedicated to multi-object spectroscopy. More than 3200 fibres will feed spectrograph…
VLBI for Gravity Probe B: The Guide Star IM Pegasi
N. Bartel, M. F. Bietenholz, D. E. Lebach +3
We review the radio very long baseline interferometry (VLBI) observations of the guide star, IM Peg, and three compact extragalactic reference sources, 3C 454.3, B2250+194, and B22…
The Emission Nebula Sh 2-174: A Radio Investigation of the Surrounding Region
R. R. Ransom, R. Kothes, J. Geisbuesch +2
Sh 2-174 is believed to be either a planetary nebula (PN) or ionized, ambient interstellar medium (ISM). We present in this paper 1420 MHz polarization, 1420 MHz total intensity (S…
VLBI for Gravity Probe B. VII. The Evolution of the Radio Structure of IM Pegasi
M. F. Bietenholz, N. Bartel, D. E. Lebach +3
We present measurements of the total radio flux density as well as very-long-baseline interferometry (VLBI) images of the star, IM Pegasi, which was used as the guide star for the…
VLBI for Gravity Probe B. VI. The Orbit of IM Pegasi and the Location of the Source of Radio Emission
R. R. Ransom, N. Bartel, M. F. Bietenholz +4
We present a physical interpretation for the locations of the sources of radio emission in IM Pegasi (IM Peg, HR 8703), the guide star for the NASA/Stanford relativity mission Grav…
VLBI for Gravity Probe B. II. Monitoring of the Structure of the Reference Sources 3C 454.3, B2250+194, and B2252+172
R. R. Ransom, N. Bartel, M. F. Bietenholz +5
We used 8.4 GHz VLBI images obtained at up to 35 epochs between 1997 and 2005 to examine the radio structures of the main reference source, 3C 454.3, and two secondary reference so…
VLBI for Gravity Probe B. IV. A New Astrometric Analysis Technique and a Comparison with Results from Other Techniques
D. E. Lebach, N. Bartel, M. F. Bietenholz +7
When VLBI observations are used to determine the position or motion of a radio source relative to reference sources nearby on the sky, the astrometric information is usually obtain…
VLBI for Gravity Probe B. V. Proper Motion and Parallax of the Guide Star, IM Pegasi
M. I. Ratner, N. Bartel, M. F. Bietenholz +4
We present the principal astrometric results of the very-long-baseline interferometry (VLBI) program undertaken in support of the Gravity Probe B (GP-B) relativity mission. VLBI ob…
VLBI for Gravity Probe B. III. A Limit on the Proper Motion of the "Core" of the Quasar 3C 454.3
N. Bartel, M. F. Bietenholz, D. E. Lebach +5
We made VLBI observations at 8.4 GHz between 1997 and 2005 to estimate the coordinates of the "core" component of the superluminal quasar, 3C 454.3, the ultimate reference point in…
