Your thesaurus codes are: missing; you have not inserted them ASTRONOMY AND ASTROPHYSICS Abstract. We have observed with the BeppoSAX satellite the quiescent counterpart of the Soft Gamma-ray Repeater SGR 1806–20. Observations performed in October 1998 and in March 1999 showed that this pulsar continued its long term spin-down trend at an average rate of ∼8 10 −11 s s −1 while its flux and spec...

We have phase connected a sequence of Rossi X-ray Timing Explorer Proportional Counter Array observations of SGR 1806−20 covering 178 days. We find a simple secular spin-down model does not adequately fit the data. The period derivative varies gradually during the observations between 8.1 and 11.7 × 10−11 s s−1 (at its highest, ∼40% larger than the long term trend), while the average burst rate...

I read with great interest the article on Benjamin Bell which appeared in the last volume of the Journal. Its author cannot have realised that in the Practitioner of June 1977 I wrote a similar article entitled ‘Benjamin Bell, 1749 to 1806’ without however his erudite comments on Bell’s surgical practice, writings and reputation. Obviously Mr Macintyre did not know of my article when he compile...

Soft Gamma Repeaters (SGRs) undergo changes in their pulse properties and persistent emission during episodes of intense burst activity. SGR 1900+14 has undergone large flux increases following recent burst activity. Both SGR 1900+14 and SGR 1806−20 have shown significant changes in their pulse profile and spindown rates during the last several years. The pulse profile changes are linked with t...

The multi-wavelength observations of the 2004 December 27 Giant Flare (GF) from SGR 1806−20 and its long-lived radio afterglow are briefly reviewed. The GF appears to have been produced by a dramatic reconfiguration of the magnetic field near the surface of the neutron star, possibly accompanied by fractures in the crust. The explosive release of over 10 erg (isotropic equivalent) powered a one...

We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from SGR 1806-20 and 190 lesser events from ...

In the last few years it has been recognized that two apparently distinct classes of peculiar high-energy sources are actually related and can be explained as young neutron stars with magnetic fields as high as 10 14 –10 15 Gauss. One of these " magnetars " , SGR 1806–20, has recently emitted the most powerful giant flare ever recorded. The high-energy observations of SGR 1806–20 carried out wi...

A nomenclatural review of Sarcoramphus vultures resulted in the following: The genus Sarcoramphus was described by Duméril in 1805 rather than 1806. Vultur papa Linnaeus, 1758, is the type of Sarcoramphus by subsequent monotypy (Froriep in Duméril 1806), not by Vigors's (1825) designation. The type of the genus Gypagus Vieillot, 1816, is, by monotypy, Vultur gryphus Linnaeus, 1758, not Vultur p...
