Abstract Key words:
The Crab-like SNR G21.5-0.9 was observed in the X-ray
band (0.5-10 keV) by the XMM-Newton satellite for over 100 ks.
The large effective area of the EPIC instrument has
allowed us to perform a deep search for pulsations from the
central core of G21.5-0.9. No pulsations were found with upper limits
on the pulsed fraction between 7.5% and 40% (depending on
frequency and energy range).

The OpenURL standard is a protocol for transmission of metadata describing the resource that you wish to access.
An OpenURL link contains article metadata and directs it to the OpenURL server of your choice. The OpenURL server can provide access to the resource and also offer complementary services (specific search engine, export of references...). The OpenURL link can be generated by different means.
- If your librarian has set up your subscription with an OpenURL resolver, OpenURL links appear automatically on the abstract pages.
- You can define your own OpenURL resolver with your EDPS Account. In this case your choice will be given priority over that of your library.
- You can use an add-on for your browser (Firefox or I.E.) to display OpenURL links on a page (see http://www.openly.com/openurlref/). You should disable this module if you wish to use the OpenURL server that you or your library have defined.
