摘要: This paper corrects the explanation given by Oliveira and Hartnett, Found. Phys. Lett. 19(6), 519–535, 2006 for the luminosity distance in Cosmological General Relativity. The mathematical expression...关键词: Carmeli’s cosmology luminosity distance angular size surface brightness ...
In the Magellanic Clouds, however, all the Cepheids are about the same distance from us, so that their apparent brightness reflects their real brightness, or luminosity.

Apparent magnitude, on the other hand, is a measure of brightness when the star is seen from Earth – hence, it takes into account the distance between the star and the Earth. You can find it with the apparent magnitude calculator, using the following equation: m=M−5+5log10(D)m...
(x, y) is the normalized particle density in the trans- verse (x–y) plane of beam 1 (2) at the IP.2 With the standard assumption that the particle densities can be factorized into 1 There exist multiple definitions of the concept of beam brightness, depending on the type of beam ...
Since pixel saturation could influence the energy–luminosity correlation, such circumstance must be limited to properly interrelate the amount of thermal energy released from the discharge to its brightness. Because of this, an adequate selection of the camera diaphragm position was found to obtain a...
The result is a smooth luminosity surface (LS) of the background brightness. Three types of lowpass filters are used, and they are the median filter, mean filter and inverse distance filter. Figure 3 shows the LSs of the green channel obtained using the median, mean and inverse distance ...
Because Equation (9) is based on the average galaxy for the large volumes, we doubled the average densities from Equation (9) for distances of 30 and 50 Mpc to account for galaxies with sizes similar to the MW (Table 3, Figure 15b). For galaxies up to the distance of 250 Mpc (...
To apply this procedure we shifted down the much more luminous light curve of the 2002 outburst of V838 Mon [2,39,63] by 6.96.9 mag, to have its peak at the same brightness as that of A13db1417. We then superimposed the light curve of the outburst of V838 Mon on A13db1417. Figu...
