NASA selects two proposals for missions to observe X-ray and far-infrared wavelengths of light from space for additional ...

New findings using data from NASA's IXPE (Imaging X-ray Polarimetry Explorer) mission offer unprecedented insight into the shape and nature of a structure important to black holes called a corona.

The chapter starts with a historical review of interferometry, going back to the Michelson works and the van Cittert‐Zernike theorem. This is useful for putting into context all definitions and ...

The work presented in this thesis shows the results from an in-depth study of a sample of 58 Be stars observed between the years 1998 and 2022. The spectroscopy of this sample has been studied, ...
