As a key feature, NASA's Parker Solar Probe (PSP) and ESA-NASA's Solar Orbiter (SO) missions cooperate to trace solar wind and transients from their sources on the Sun to the inner…
Hands-on learning at a world-class telescope
Elisabeta Lusso, Lapo Casetti, Maurizio Pancrazzi +1
For the first time, an Italian University has the possibility to perform a multi-year observing campaign at a world-class telescope. This hands-on experience had a significant impa…
The optically elusive, changing-look active nucleus in NGC 4156
Giulia Tozzi, Elisabeta Lusso, Lapo Casetti +21
We report on the changing-look nature of the active galactic nucleus (AGN) in the galaxy NGC 4156, as serendipitously discovered thanks to data acquired in 2019 at the Telescopio N…
Observation of Magnetic Switchback in the Solar Corona
Daniele Telloni, Gary P. Zank, Marco Stangalini +49
Switchbacks are sudden, large radial deflections of the solar wind magnetic field, widely revealed in interplanetary space by the Parker Solar Probe. The switchbacks' formation mec…
