Mrk 421 Campaign

Subscribe to Syndicate

Newcastle Observatory is participating in a concerted multi-wavelength campaign to observe Markarian 421 - a BL Lacerta type object.

The goals are to study the flux over a long baseline and over timescales as short as a few minutes.  This will provide opportunity to gather data should the source flare. These observations will permit a better understanding of the underlying physics in Markian 421 in particular, and in BL Lacerta objects in general.

The 0.4m telescope at Newcastle Observatory will be used to take time-series exposures over many hours per night in the BVRcIc bands. This time-series coincides with observations taken by RXTE, SWIFT, VERITAS, Whipple, and MAGIC instruments.

Further information on the campaign can be found here.
