[Q]: An offshoot of this faith known as the Azali was considered the true belief system by E. G. Browne, a 19th and 20th century authority on many of its writings. Two martyrs for this religion were eulogized as the "Twin Shining Lights" in a text written to the son of Aga Najafi, also called the "wolf" by this religion's founder. The dogmas of this religion can be summarized as unity of God, unity of humanity, and unity of religion, and several other key tenets are found in its holy book, the Kitab-i-Aqdas. Shoghi Effendi served as "Guardian" of this faith during the 20th century, and it was founded by a man whose name translates to Glory of God and who took on the mantle and adopted many of the teachings of the Bab. For 10 points, name this Persian religion founded by Baha'ullah.
[A]: Social Science


[Q]: Lin and Shu proposed the density-wave theory to explain how the structure of these entities is sustained. The most accurate method for measuring the distances to distant ones uses a relation between their maximum rotational velocity and absolute magnitude, which is known as the Tully-Fisher method. They are generally blue because of their high content of old stars, and one type of them features arms that emanate from each end of a namesake structure. They have discs like the lenticular type, but contain much more angular momentum than the elliptical type. FTP name these galaxies, some of which are barred, including the Milky Way.
[A]: Science


[Q]: One type of this phenomenon was measured using a Fe-57 detector in the Harvard Tower experiment. This effect produces the first-degree anisotropy in the CMBR. Recombination of hydrogen atoms occurred at a value of approximately 1100 for the quantity associated with this effect, whose cosmological variety increases with age and distance; that is because the universe is (*) expanding according to Hubble's law. A few objects, such as Andromeda, exhibit the opposite of this effect, because they are moving towards us. For 10 points, name this phenomenon, in which the wavelength of astronomical objects receding from Earth broadens, producing a namesake change in color.
