1Msec pictures

[Lawrence Rudnick <larry@astro.umn.edu>]

Una has put two new links on the web site. One is to the gif of the 1Msec
image with 0.2 pixel or so registration for which i circulated the
ftp address.

the other image is fabled below:

We've started looking at the comparison between deepest radio and
1Msec broadband images.  The most obvious thing that shows up are
a number of features 'outside' the forward shock, (most notably
the bow-shaped feature to the north) that we knew about in radio
but hadn't seen in xray yet.  we'll have to discuss significance
of this, may not be much...

in the meantime, the counterjet has encountered a little 'trouble'.
the southernmost of the three filaments has a couple of bends, and
a likely flaring at the end, as seen in the attached gif.  this
is broadband, convolved to 5", overlaid with contours of the same
image run through a simple high pass filter. this could be a little
problematic, or interesting, depending on your view on life.  not so
easy to bend a dense clump travelling ballistically, without
immediately disrupting it. and, since these 'counterjets' seem to
have little or no finestructure, not clear that a simple ballistic
picture of clumps being successively ejected was a good way to think
about this anyway, although fesen's work shows that there were
definitely ballistic ejections in this region. in images that are
not so burned out, it also looks like the middle filament can be
traced interior to the outer shock, and if this is right,
shows some gentle curvature, as well.
   enough stream of consciousness, enjoy the pics.
