At the Jeremiah Horrocks Institute for Mathematics, Physics and Astronomy (JHI), at the University of Central Lancashire (UCLan)
Read about our involvement with Herschel IR/submm Key Project,
in which I was a co-investigator:
Our research includes observations of dusty elliptical and lenticular galaxies
in the local universe. Follow-up observations include data from ALMA
I am a member of the consortium: Galaxy and Mass Assembly,
which studies galaxies via multi-waveband observations, imaging and spectroscopy.
I am a member of the MILES consortium, which produces some of
the most widely used stellar libraries and stellar population models.
At UCLan, with MILES consortium collaborators, we have produced a new theoretical
stellar spectral library, available from UCLanData, with information
in a README file.
Using our theoretical spectra, we have also produced a semi-empirical stellar library,
based on MILES stars, with varying [α/Fe], see link to sMILES (in Firefox).

Local Group and beyond
The Local Group is a weakly bound group of galaxies, within a region of space about 2 Megaparsecs across,
including our Milky Way and its satellites. The image below shows the location of galaxies in the Local Group,
colour coded according to their type (see the key). The solid lines show galaxies above the plane and the
dotted lines show galaxies below the plane. Image credit: Brandner and Grebel.
Beyond the Local Group are other groups and clusters of galaxies. To explore the local region of the Universe see: Local Group
See images of galaxies in their 3-d space locations, in a fly-through of data from the Galaxy and Mass Assembly survey
in one of the three equatorial fields mapped by GAMA, showing filamentary and clustering structure, out to about redshift z=0.4.
