We utilize the concept of sparsity or compressibility to develop an new generation of inversion codes for the Stokes parameters. The inversion code uses...
New Global Mass Functions and Structural Parameters for Galactic Globular Clusters
The HST/ACS Survey of Galactic Globular Clusters includes F606W and F814W observations of 66 clusters (Sarajedini et al. 2007). We present new global mass...
New Ground Based facilities in QSO research; The GTC
New ground based observing opportunities are becoming, or about to become, available to astronomers for QSO research. These, combined with state of the art...
The 1.5m solar telescope GREGOR is being constructed at Tenerife, Spain. Its purpose is to observe with high spatial and spectral resolution small-scale dynamic...
New horizons in cosmology with spectral distortions of the cosmic microwave background
This Voyage 2050 paper highlights the unique science opportunities using spectral distortions of the cosmic microwave background (CMB). CMB spectral distortions...
It is pointed out that the phenomenon of solar rotation is known since the introduction of the telescope into astronomy by Galilei in 1610. Regular measurements...
