First solar observations with ALMA
Loukitcheva, Maria
The Atacama Large Millimeter-Submillimeter Array (ALMA) has opened a new window for studying the Sun via high-resolution high-sensitivity imaging at millimeter wavelengths. In this contribution I review the capabilities of the instrument for solar observing and describe the extensive effort taken to bring the possibility of solar observing with AL…
The dynamic chromosphere: Pushing the boundaries of observations and models
Pereira, Tiago M. D.
The interface between the bright solar surface and the million-degree corona continues to hold the key to many unsolved problems in solar physics. Advances in instrumentation now allow us to observe the dynamic structures of the solar chromosphere down to less than 0.″1 with cadences of just a few seconds and in multiple pola…
