An investigation of the active galaxies M82 and NGC 5128 [PDF]
, 1995 In this thesis we present multi-waveband imaging polarimetry and spectropolarime- try of the starburst galaxy M82 and multi-waveband imaging polarimetry of the active galaxy NGC 5128. A review of previous studies of these galaxies is given.

Magnetic fields in nearby galaxies [PDF]
, 2009 We describe a recent full-polarization radio continuum survey, performed using the Westerbork Synthesis Radio Telescope (WSRT), of several nearby galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS) sample.

The Galaxy Magnetic Field [PDF]
International Astronomical Union Colloquium, 1977 The origin and dynamics of magnetic fields depend crucially on the dynamics of a gas in the Galaxy. In turn the magnetic field is needed to isotropize the cosmic rays (the influence on chemistry) and is of importance for the formation of stars (local dynamics). Thus the appearance of this topic at the Colloquium is justified.

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
Astronomische Nachrichten, EarlyView.ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Magnetic Fields with the Atacama Large Millimeter/Submillimeter Array [PDF]
, 2014 The Atacama Large Millimeter/submillimeter Array (ALMA) is one of the largest radio telescopes and is located at 5, 000 m altitude in the Atacama desert in Chile. Its unprecedented sensitivity at extremely high angular and spectral resolution in the (sub-

Magnetic fields in O-type stars measured with FORS 1 at the VLT [PDF]
, 2009 The presence of magnetic fields in O-type stars has been suspected for a long time. The discovery of such fields would explain a wide range of well documented enigmatic phenomena in massive stars, in particular cyclical wind variability, Hα emission ...

Anterior Drawer Maneuver to Access Knee Posteromedial Compartment
Arthroscopy Techniques, EarlyView.Abstract Over the years, diagnostic arthroscopy has been the key to accurately diagnosing lesions in the knee. However, accessing the posterior compartment of the knee remains a challenge for upcoming arthroscopy surgeons. Gillquist was the first surgeon to publish a technique for accessing the posteromedial compartment in 1979, following which several

A polarisation study of spiral galaxies [PDF]
, 1987 Optical polarimetry results are presented for four spiral galaxies: NGC 5194 (M51), NGC 1068, NGC 4565 and NGC 4594 (Ml04). M51 and NGC 1068 show spiral polar isation patterns which are interpreted as indicating a spiral magnetic field in each case.

Turbulence in the interstellar medium [PDF]
, 2014 Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...
