Observations for the U.S. key project on quasars using ISO were completed in April when the satellites cryogen supply expired. This proceeding presents an update of the project, including information on the final sample, a discussion of some of the data reduction challenges and current efforts to meet them, plus a comparison of preliminary results with IRAS fluxes.
The U.S. ISO Key Project on quasar spectral energy distributions seeks to better understand the very broad-band emission features of quasars from radio to X-rays. A key element of this project is observations of 72 quasars with the ISOPHOT instrument
In this contribution we schematically summarize a number of ongoing, coordinated spectro-photometric projects devoted to the study of the stellar population properties in Omega Cen. All of these investigations are part of a global comprehensive proje
We perform a survey of the X-ray properties of 41 objects from the WISE/SDSS selected Hyper-luminous (WISSH) quasars sample, composed by 86 broad-line quasars (QSOs) with bolometric luminosity $L_{Bol}geq 2times 10^{47},erg, s^{-1}$, at z~2-4. All bu
Studying the coupling between the energy output produced by the central quasar and the host galaxy is fundamental to fully understand galaxy evolution. Quasar feedback is indeed supposed to dramatically affect the galaxy properties by depositing larg
We present the specifications of the MeerKAT Karoo Array Telescope, the South African Square Kilometre Array Precursor. Some of the key science for MeerKAT is described in this document. We invite the community to submit proposals for Large Key Projects.
