The effective radius of a galaxy, often denoted as \( R_e \) or \( r_{\text{eff}} \), is a key parameter in astronomy that describes the size of a galaxy in terms of its brightness distribution. Specifically, it is defined as the radius within which half of the total light (or luminosity) of the galaxy is contained.

Czado has published a variety of papers and often collaborates on projects that involve complex statistical methods to analyze real-world data.
Halbert White is a prominent statistician and econometrician known for his contributions to the fields of econometrics and statistical theory. One of his significant contributions is the development of robust standard errors, which address issues of heteroskedasticity (non-constant variance) in the context of regression analysis. This work is particularly influential in ensuring valid inference in econometric models when the assumptions of traditional ordinary least squares regression are violated.
Hans-Rudolf Künsch is a notable Swiss statistician, recognized for his contributions to the field of statistics, particularly in areas related to time series analysis, statistical inference, and the theory of stochastic processes. He is known for developing methods related to empirical processes and also for his work in nonparametric statistics.
Harold Jeffreys (1891–1989) was a prominent British mathematician, statistician, and geophysicist known for his contributions to various fields, including Bayesian statistics, geophysics, and the study of earthquakes. He played a significant role in the development of Bayesian methods in statistics, advocating for the use of subjective probabilities based on prior knowledge and evidence in statistical analysis.
Peter Diggle is a prominent statistician known for his work in the field of spatial statistics and epidemiology.

The 15th century was a significant period for mathematics, particularly because it was part of the broader Renaissance movement, which saw a revival of interest in science and learning. Here are some key mathematicians and developments from the 15th century: 1. **Fibonacci (Leonardo of Pisa, c. 1170-1250)**: Although he lived earlier than the 15th century, Fibonacci’s work laid important foundations for later mathematicians.
Immittance is a term used in electrical engineering and electronics to refer to the combined effects of resistance and reactance in an electrical circuit. It is a complex quantity that encompasses both the resistance (real part) and the reactance (imaginary part) of a circuit element or network.
