Using cm Observations to Constrain the Abundance of Very Small Dust Grains in Galactic Cold Cores
C. T. Tibbs, R. Paladini, K. Cleary +9
In this analysis we illustrate how the relatively new emission mechanism known as spinning dust can be used to characterize dust grains in the interstellar medium. We demonstrate t…
AMI Galactic Plane Survey at 16 GHz: II -- Full data release with extended coverage and improved processing
Yvette C. Perrott, Anna M. M. Scaife, David A. Green +5
The Arcminute Microkelvin Imager Galactic Plane Survey (AMIGPS) provides mJy-sensitivity, arcminute-resolution interferometric images of the northern Galactic plane at 16…
CARMA Observations of Galactic Cold Cores: Searching for Spinning Dust Emission
C. T. Tibbs, R. Paladini, K. Cleary +9
We present the first search for spinning dust emission from a sample of 34 Galactic cold cores, performed using the CARMA interferometer. For each of our cores we use photometric d…
The peculiar radio galaxy 4C 35.06: a case for recurrent AGN activity?
A. Shulevski, R. Morganti, P. D. Barthel +85
Using observations obtained with the LOw Fequency ARray (LOFAR), the Westerbork Synthesis Radio Telescope (WSRT) and archival Very Large Array (VLA) data, we have traced the radio…
Multiscale Analysis of the Gradient of Linear Polarisation
J. -F. Robitaille, A. M. M. Scaife
We propose a new multiscale method to calculate the amplitude of the gradient of the linear polarisation vector using a wavelet-based formalism. We demonstrate this method using a…
SKA Deep Polarization and Cosmic Magnetism
A. R. Taylor, Ivan Agudo, Takuya Akahori +10
Deep surveys with the SKA1-MID array offer for the first time the opportunity to systematically explore the polarization properties of the microJy source population. Our knowledge…
Measuring magnetism in the Milky Way with the Square Kilometre Array
Marijke Haverkorn, Takuya Akahori, Ettore Carretti +17
Magnetic fields in the Milky Way are present on a wide variety of sizes and strengths, influencing many processes in the Galactic ecosystem such as star formation, gas dynamics, je…
Magnetic Field Tomography in Nearby Galaxies with the Square Kilometre Array
George Heald, Rainer Beck, W. J. G. de Blok +16
Magnetic fields play an important role in shaping the structure and evolution of the interstellar medium (ISM) of galaxies, but the details of this relationship remain unclear. Wit…
