Scientists make first discovery using revolutionary long wavelength demonstrator array

(Washington, DC ? 08/18/09) -- Scientists from NRL's Space Science and Remote Sensing Divisions, in collaboration with researchers from the University of New Mexico (UNM) and the National Radio Astronomy Observatory (NRAO) located in Socorro, N.M., have generated the first scientific results from the Long Wavelength Demonstrator Array (LWDA).

Pinpointing origin of gamma rays from a supermassive black hole

An international collaboration of 390 scientists reports the discovery of an outburst of very-high-energy (VHE) gamma radiation from the giant radio galaxy Messier 87 (M 87), accompanied by a strong rise of the radio flux measured from the direct vicinity of its super-massive black hole.

Surprising Image Revises Understanding of Dwarf Galaxies

An intensive study of a neighboring dwarf galaxy has surprised astronomers by showing that most of its molecular gas -- the raw material for new stars -- is scattered among clumps in the galaxy's outskirts, not near its center as they expected. "This tells us that the galaxies we call dwarf irregulars are even more irregular than we thought," said Fabian Walter, of the National Radio Astronomy Observatory (NRAO) in Socorro, NM. "Our new work also shows that these galaxies probably are useful 'laboratories' for studying how stars were formed when the Universe was young," Walter added.
