For web links to my research papers since 1984, use the ADS search engine and search on "Bland-Hawthorn, Bland, J." You will also need to highlight the Astrophysics, Physics and Astro-ph buttons.
These fall into two different categories: astrophysics and instrument science.
You might like to see a
review I wrote
with Ken Freeman on "The Baryon Halo of the Milky Way" (Science,
Jan 2000) or a related article in
"Clues to Galaxy Formation" (Nature, July 1999). Both of these articles
attempt to show that the time is ripe for a general convergence of
far-field cosmology and near-field cosmology (cosmogony). This is a
topic we explore in greater detail in our
Annual Reviews 2002 article. After a
successful Aspen Winter School on Near Field Cosmology in Feb 2006, Jim
Peebles and I wrote an update
on this topic.
Here is a series of audio files where I describe
our most recent work on the closest disk galaxy beyond the Local
Group. In 2005, we presented evidence in the Astrophysical Journal (ApJ) that
the galaxy stellar disk extends twice as far as was previously
believed. Using the Gemini South telescope, we reach equivalent
surface brightness levels that have never been achieved before. The
full news story is available at this site.
In 2002, I wrote two papers on "Laser Telemetry from Space" with
father and son team, Martin & Alex Harwit (Science, July 2002). The papers were adopted as a NASA white paper in
that same year and a workshop was held
at JPL to discuss the work. In early 2006, and sooner than I had ever
anticipated, a NASA Goddard team achieved
the first interplanetary laser communications over a distance of
24 million km (Science,
Jan 2006). With specific reference to my work, their paper describes how they used
the MESSENGER satellite which is on a 6.6 year voyage to Mercury and
due to arrive in early 2011. For more information, see our laser communications website.
I have written popular articles
with Gerald Cecil and Sylvain Veilleux on "Colossal Galactic Explosions"
and "The Life of a Quasar" (Scientific American, Mar. 2000).
We explore the topic of "Galactic Winds"
in greater detail in our Annual
Reviews 2005 article.
You might like to see my two entries for the
Encyclopaedia of Astronomy & Astrophysics (ed. P.G. Murdin):
"Gas in Galaxies" with Ron Reynolds, and "Tunable Imaging Filters".
Here is my recent petition to the
scientific community (Science, Aug 2006)
to recognize the extraordinary advances made possible by computational
science. Without them, we would still be contemplating von Neumann's
stalemate of 1946.
My recent appearances on ABC radio are available here as
audio files. I have made regular appearances on ABC
radio and TV since 1995.
