Jun 28, 2024 · One way to measure a galaxy’s diffuseness is to determine its half-light radius: the distance from its centre at which you can draw a circle that will encompass half the total light emitted...
6 days ago · Most globular clusters have a half-light radius of less than ten parsecs (pc), although some globular clusters have very large radii, like NGC 2419 (r h = 18 pc) and Palomar 14 (r h = 25 pc).
3 days ago · The speed at which the individual crests and troughs of a plane wave (a wave filling the whole space, with only one frequency) propagate is called the phase velocity vp. A physical signal with a finite extent (a pulse of light) travels at a different speed.
4 days ago · Galaxy’s half-light radius is twice as large as previously thought. Upon integrating the data into their model, the research team observed that the density of red giants stabilizes around the midpoint between the galaxy’s edges and its bulge. This contrasts with previous models that suggested an exponential increase in density.
Jun 27, 2024 · Compared to the Milky Way-mass disk galaxies, regardless of the presence of a bar, the half-light radius of the Milky Way based on the canonical picture of Galactic structure is extraordinarily...
4 days ago · The half-light radius is a measure used in astronomy to describe the size of an astronomical object, defined as the radius within which half of the total light (or luminosity) of the object...
