Submillimeter and millimeter wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current single-dish facilities have presented a tantalising view of the bright

Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composition of their chromospheres. Despite the fundamental progress in (sub-)

The quiet Sun at mm Wavelengths as Seen by ALMA

Autor: Alissandrakis, Costas, Bastian, Timothy, Brajša, Roman

Solar observations at sub-mm, mm and cm wavelengths offer a straightforward diagnostic of physical conditions in the solar atmosphere because they yield measurement of brightness temperature which, for optically thick features, equals intrinsic tempe

Variation in solar differential rotation and activity in the period 1964-2016 determined by the Kanzelh\'ohe data set

Autor: Beljan, I. Poljančić, Jurdana-Šepić, R., Jurkić, T., Brajša, R., Skokić, I., Sudar, D., Ruždjak, D., Hržina, D., Pötzi, W., Hanslmeier, A., Veronig, A. M.
