Differential measurement of atmospheric refraction using a telescope with double fields of view
Zhao, Ming; Yu, Yong; Cao, Jian-Jun +2 more
For the sake of advancing theoretical research about atmospheric refraction, the atmospheric refraction observed at lower angles of elevation is still worth analyzing and exploring. In some engineering applications, objects with a larger zenith distance must sometimes be observed. Carrying out observational research on atmospheric refraction at lo…
The local contribution to the microwave background radiation
Pecker, Jean-Claude; Narlikar, Jayant V.; Ochsenbein, Francois +1 more
The observed microwave background radiation (MBR) is commonly interpreted as the relic of an early hot universe, and its observed features (spectrum and anisotropy) are explained in terms of properties of the early universe. Here we describe a complementary, even possibly alternative, interpretation of MBR, first proposed in the early 20th
