... Energy Levels . ... Examining the Balmer formula and also the Ritz combination principle (further below), Bohr suggested that atoms could exist (even briefly) only in certain energy levels , and light was emitted only when an atom descended from some higher energy level to a lower one. ... When an electron descends from a higher energy (large n) to a lower one (smaller n), by Balmer's formula together with Einstein's, the energy of the photon emitted was exactly the amount of energy given up: . ...

Q: Are the magnitudes in the ETCs AB or Vega magnitudes? ... Q: How is the signal to noise defined? A: In optical and infrared imaging, the applications display a signal to noise over the PSF area, which is computed in a circle of radius seeing/plate_scale. ... In optical imaging only, a second signal to noise is computed which is the signal to noise at the central pixel. ... A: The template spectra stored in the database are measured or simulated spectra covering different wavelength range. ...

... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...
