... There are many pitfalls in these kind of comparisons, which are described in great detail in the papers I have used to compare my impact on the field. In the first comparison I use the method described by Pijpers (2006, Astronomy Geophysics, 47, 6.17) , where he compares the total normalized citation rate per paper (i.e., the number of citations of a paper divided by the number of authors) to the total number of papers for different authors in the field of space research. ... 1st year paper . ...

(2006) developed a method to determine such a limit if (and only if) the pulsar timing residuals were statistically white. In the paper we used data from six pulsars from the PPTA project to obtain a limit. The remaining pulsars were rejected because their timing residuals were not white. ...

We can use the colors of Europa s surface to tell us about the chemical compounds that make up the surface and subsurface of the jovian moon. Even before the first spacecraft made a close visit to Europa, astronomers on Earth used telescopes to study the moon and were able to use a technique called spectroscopy to determine that Europa s surface is composed mostly of water ice. ...
