TeV Cherenkov Events as Bose-Einstein Gamma Condensations (2007)
Martin Harwit Protheroe, Martin Harwit, R. J. Protheroe, P. L. Biermann
The recent detection of gamma radiation from Mkn 501 at energies as high as 25 TeV suggests stringent upper bounds on the diffuse, far infrared, extragalactic radiation density. The production of...

THERMAL WATER VAPOR EMISSION FROM SHOCKED REGIONS IN ORION 1 (2007)
Martin Harwit, David A. Neufeld, Michael J. Kaufman
Using the Long Wavelength Spectrometer on board the Infrared Space Observatory, we have observed thermal water vapor emission from a roughly circular field of view approximately 750 in diameter...
Leisawitz, David, Armstrong, Tom, Bender, Chad, Benford, Dominic, Calzetti, Daniella, Carpenter, John, ...
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 - 400 micron wavelength range, a far-IR interferometer will revolutionize our understanding of planetary system...
Leisawitz, David, Baker, Charles, Barger, Amy, Benford, Dominic, Blain, Andrew, Boyle, Rob, ...
We report results of a recently-completed pre-Formulation Phase study of SPIRIT, a candidate NASA Origins Probe mission. SPIRIT is a spatial and spectral interferometer with an operating wavelength...
SWAS observations of comet 9P/Tempel 1 and Deep Impact (2005)
Bensch, Frank, Melnick, Gary J., Neufeld, David A., Harwit, Martin, Snell, Ronald L., Patten, Brian M.
On 4 July 2005 at 1:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the...
Observations of Water Vapor Outflow from NML Cygnus (2004)
Zubko, Viktor, Li, Di, Lim, Tanya, Feuchtgruber, Helmut, Harwit, Martin
We report new observations of the far infrared and submillimeter water vapor emission of NML Cygnus based on data gathered with the Infrared Space Observatory and the Submillimeter Wave Astronomy...

Photon Orbital Angular Momentum in Astrophysics (2003)
Astronomical observations of the orbital angular momentum of photons, a property of electromagnetic radiation that has come to the fore in recent years, have apparently never been attempted. Here, I...
Chemical Composition of the Early Universe (2003)
A prediction of standard inflationary cosmology is that the elemental composition of the medium out of which the earliest stars and galaxies condensed consisted primarily of hydrogen and helium 4He...
557 GHz Observations of Water Vapor Outflows from VY CMa and W Hydrae (2001)
Harwit, Martin, Bergin, Edwin A.
We report the first detection of thermal water vapor emission in the 557 GHz, $1_{10} - 1_{01}$ ground state transition of ortho-H$_2$O toward VY Canis Majoris. In observations obtained with the...
