We will do this by proving a more general theorem – that for any two axons of different diameter, if their physical properties along the length of the axon are identical when position is scaled by the square root of diameter, then their behavior will be identical in this scaled c ...

Unlocking the secrets of stellar haloes using combined star counts
... In recent years, most attempts to trace the surface brightness profiles of stellar haloes have been based on direct star counts, i.e. by counting the number of bright halo stars (red giant branch stars, asymptotic giant branch stars and upper main sequence stars) within a certain area. The bright st ...

Astronomical spectroscopy
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, which radiates from stars and other hot celestial objects. Spectroscopy can be used to derive many properties of distant stars and galaxies, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
