In the United States in the late 1950s and early 1960s, arms control gained traction as the preferred option for dealing with Soviet nuclear advances. The development of the first imaging satellites is often credited with enabling nuclear arms control under the conventional wisd…
In ionospheric modeling, the differential code biases (DCBs) are a non-negligible error source, which are routinely estimated by the different analysis centers of the International GNSS Service (IGS) as a by-product of their global ionospheric analysis. These are, however, estim…
The study of dwarf galaxies is of great importance to understand galaxy formation and evolution on the smallest mass scales. According to the current cosmological paradigm, galaxies grows hierarchically from the accretion of smaller systems. The dwarf galaxies that we observe to…
