Luminosity functions are used to study the properties of large groups or classes of objects, such as the stars in clusters or the galaxies in the Local Group. Note that the term "function" is slightly misleading, and the luminosity function might better be described as a luminosity distribution. Given a luminosity as input, the luminosity ...
The dashed red line is an example luminosity function when the Malmquist bias is not corrected for. The more numerous low luminosity objects are underrepresented because of the apparent magnitude limit of the survey. The solid blue line is the properly corrected luminosity function using the volume-weighted correction method.
The Press–Schechter formalism predicts that the number of objects with mass between and + is: = (+) ¯ (+) / (() (+) /). where is the index of the power spectrum of the fluctuations in the early universe (), ¯ is the mean (baryonic and dark) matter density of the universe at the time the fluctuation from which the object was formed had gravitationally collapsed, and is a cut-off mass ...
You invest $100,000 in a rental home with a friend to be used as a passive income generator. Ten years later, the principal mortgage is paid off and the investment is worth $150,000. You’re ...
Paul L. Schechter (born May 30, 1948) is an American astronomer and observational cosmologist. He is the William A. M. Burden Professor of Astrophysics, Emeritus, at MIT . Schechter received his bachelor's degree from Cornell in 1968, and his Ph.D. degree from Caltech in 1975.
Forget Chip and Joanna Gaines, bowerbirds are the real home renovation stars! These incredible avian artists have a keen eye for color and are masters of interior design, spending countless hours ...
TikTok is filled with tips and tricks — some legitimate, many not — to help you sleep better. One of the latest encourages people to follow a 10-3-2-1-0 sleep rule, which is actually not just ...
The disjoint union of the above two examples is locally compact in sense (1) but not in senses (2), (3) or (4). The right order topology on the real line is locally compact in senses (1) and (3) but not in senses (2) or (4), because the closure of any neighborhood is the entire non-compact space.
