The data-driven ORDEM covers a spectrum of object size from 10 μm to greater than 1 m, and ranging from LEO (low Earth orbit) to GEO (geosynchronous orbit) altitude regimes.
When you take a spectrum of fluorescing objects like galaxies, you see that the spectrum is not smooth, but made up of a number of lines.
These 'object-vector cells' are tuned equally to a spectrum of discrete objects, irrespective of their location in the test arena, as well as to a broad range of dimensions and shapes, from point-like objects to extended surfaces.
We can use this file to extract a spectrum of the object in energy space and find the peak energy.
FIRST also can simultaneously obtain a spectrum of each object, providing critical information on the chemical composition and temperature of the stars, debris disks or planets, he said.
To measure the distance to the galaxy, lead author Matthew Lehnert of the Paris Observatory, Nicole Nesvadba of the University of Paris, and their colleagues took a spectrum of the object using a spectrograph mounted on the European Southern Observatory's Very Large Telescope in Chile.
But it also brings together a whole spectrum of objects that show the delicacy, the sophistication, the marvelous complexity, the subtlety and the fantastic beauty of Ottoman art".
Meech is now hoping to get telescope time in the next month before the object becomes too faint to observe to get a spectrum of the second object that would more definitively show whether its surface properties match those of inner solar system asteroids.
Frequency bands in a spectrum of light from an unknown object compared with bands from known samples can reveal the object's composition.
The Holometer is a Michelson interferometer-based device optimized to detect the resulting, characteristic position noise spectrum of objects apparently at rest in the space-time.
Frequency peaks in a spectrum of light from an unknown object compared with bands from known samples can reveal the materials of the object.
