The enigmatic radio emission from θ 1 Orionis A

The bright star θ1 Orionis A, the third most luminous OB star in the Orion Trapezium Cluster, is known as a strongly variable non-thermal radio source. The physical nature of the emission mechanism has been a matter of debate since almost two decades. In this contribution we re-analyse available radio data in combination with near-infrared observations to investigate the radio-emission mechanis...

Separating the Sources of the Crab’s Enigmatic Radio Emission

We propose to study the Crab pulsar using scintillometry techniques. Expanding the approach of Pen et al. (2014), we plan to map the apparent positional shift of the various pulse components, focussing on the precursor, main pulse and interpulse. From earlier observations, these have been found to have rather different properties and therefore been suggested to originate in different parts of t...

[An enigmatic eye in an enigmatic bust].

have read with interest the article published in the iconoraphic section of this Journal by Drs. Diez-Lage and González nd titled The enigmatic eye of Nefertiti.1 After publishing a eview on the topic in the February issue of the British Journal f Ophthalmology,2 I would like to make a few comments. Queen Nefertiti (c. 1370–1330 AC) was the Great Royal Wife f Akhenaton (Amenhotep or Amenophis I...
