Some of my Recent(ish) Research
The Hubble constant from HST observations of M96
I have recently published a paper on the distance to
M96 in the
Leo I group (ground-based photograph of centre of group).
You can view a
ground-based CCD image of the whole galaxy
taken with the 2.5m Isaac Newton Telescope on La Palma,
portion (about 25%) of the HST image showing resolved stars
in a spiral arm.
If you want to see how the 3 pictures fit together
I have created a

Calibration of the Cepheid PL Relation
I have done some work on the calibration of the Cepheid PL
relation, particularly using the Cepheids in the Large
example of the PL relation one finds.
for further details.
Observations of the Crab nebula
These observations are of the central region of the nebula
around the pulsar and show the evolution of the synchrotron
wisps. A paper describing them recently appeared in the New Astronomy
journal and is
available electronically (including a movie).
Some more pretty pics

This picture is of the nearby barred spiral galaxy M95 or NGC3351.
It was taken with the LDSS-2 instrument in imaging mode, on the
4.2m William Herschel Telescope on La Palma. Images taken
in three filters (red, green and blue) were combined to
create this "true colour" picture.
The Leo triplet of galaxies, M105, NGC3384 and NGC3389.
CCD images obtained on the 2.5m Isaac Newton Telescope.
Some CCD images of fields in the Large Magellanic Cloud (taken
at the 1.54m Danish telescope at La Silla).
