Dave Green's research
My Catalogue of
Galactic Supernova Remnants (SNRs) contains details of 303 SNRs
(last revised: 2022 December).
The last published version is:
- Green, D. A., 2015, "Constraints on the distribution of supernova
remnants with Galactocentric radius",
Recent studies of the very young Galactic supernova remnant
Some time ago I wrote a book with F. R. Stephenson on Historical
Supernovae and their Remnants, which is published by Oxford
University Press (2002 August).
Other work on SNRs is included in my list of recent papers below.
Here are some other photos
of the GMRT and surroundings, and also of a visit to
In recent years much of my observational research has involved observations
with the Giant Metrewave Radio
Telescope (GMRT), near Pune, India.
2.1) Deep extragalactic surveys
These observations include a deep (1σ noise of about 30 μJy
beam−1 at best) 610-MHz survey of the Spitzer extragalactic
First Look Survey (FLS) region. These cover about 4 square degrees, with a
mosaic of seven pointings, with a resolution of about 5 arcsec, and detected
nearly four thousand sources. These observations are published in:
A deep 610-MHz
image of (a small portion of) the Spitzer extragalactic First Look
Survey region. The resolution is about 5 arcsec, and the r.m.s.
noise about 30 μJy beam−1
The other regions processed so far are the ELAIS-N1 and ELAIS-N2 fields, and
the Lockman Hole field. These observations are

First Look Survey field -- I. Observations, data analysis and source

The source catalogues and survey images are also available: FLS, ELAIS-N1, ELAIS-N2, Lockman Hole.

2.3) Useful AIPS tasks
Other users of the GMRT may find the following (classic) AIPS tasks that I have written useful:
- UVFXT, to correct for slight time error -- and hence
uvw coordinate errors -- in GMRT uv FITS data produced at the
telescope before mid-2006;
- UVFLP, to flip the order of the channels in a uv
database, so that LSB data can be combined with USB data in AIPS, using DBCON.
(Recent versions of AIPS, 31DEC07 and later, now contain a task -- FLOPM --
which can do the flipping of channels.)
Users of AIPS should also note that there were various bugs in SPLAT/SPLIT
tasks, when averaging spectral channels, which were patched in the 31DEC06 and
31DEC07 versions of AIPS in Oct/Nov 2007. Some of these bugs applied only to
more recent uv datasets written at the GMRT that combine both sidebands
into one file, but others apply to single sideband uv datasets also. See
patches 17, 18 and
19 for more details.
Here is a list of my published and submitted
research papers. This includes the following recent work (see also the papers
listed under SNRs or the GMRT above):
