Probing the Rosette Nebula Stellar Bubble with Faraday Rotation
, 2013 We report the results of Faraday rotation measurements of 23 background radio sources whose lines of sight pass through or close to the Rosette Nebula. The Rosette Nebula is an excellent candidate for studies of super bubbles associated with young star ...

Floating zone growth of high‐purity MgO substrate single crystals
Acta Crystallographica Section B, EarlyView.High‐purity MgO substrate crystals grown by the optical floating zone technique are demonstrated, which can serve as a foundation for the development of novel device concepts based on epitaxially grown thin films.MgO single crystals with diameters between 3.5 and 5 mm and lengths up to 40 mm were grown by the optical floating zone technique (OFZ ...

The Crab Nebula Revisited Using HST/WFC3
The Astrophysical JournalIt has been over 24 years since the iconic Crab Nebula has been visited by the high spatial resolution eye of the Hubble Space Telescope (HST). The expanding nebula is dynamic on these timescales, with many of the outer filaments of the nebula known to ...

Modelling the ArH$^+$ emission from the Crab Nebula [PDF]
, 2017 We have performed combined photoionization and photodissociation region (PDR) modelling of a Crab Nebula filament subjected to the synchrotron radiation from the central pulsar wind nebula, and to a high flux of charged particles; a greatly enhanced ...

Three Stages in Evolution of the Object Th4-4
GalaxiesThe results of observations of the object Th4-4 in 1970–2024 showed that during this period the object went through several stages, when its characteristics corresponded to different classes of objects: Be star, symbiotic star and planetary nebula ...
