Extragalactic Astronomy with the VLTI: a new window on the Universe [PDF]
Astrophysics and Space Science, 2003 Interferometry in the optical and near infrared has so far played a marginal role in Extragalactic Astronomy. Active Galactic Nuclei are the brightest and most compact extragalactic sources, nonetheless only a very limited number could be studied with speckle interferometry and none with long baseline interferometry.

Extragalactic radio continuum surveys and the transformation of radio astronomy [PDF]
Nature Astronomy, 2017 Next-generation radio surveys are about to transform radio astronomy by discovering and studying tens of millions of previously unknown radio sources. These surveys will provide new insights to understand the evolution of galaxies, measuring the evolution of the cosmic star formation rate, and rivalling traditional techniques in the measurement of ...

Multivariate Approaches to Classification in Extragalactic Astronomy [PDF]
Frontiers in Astronomy and Space Sciences, 2015 Clustering objects into synthetic groups is a natural activity of any science. Astrophysics is not an exception and is now facing a deluge of data. For galaxies, the one-century old Hubble classification and the Hubble tuning fork are still largely in ...

Proton and neutrino extragalactic astronomy [PDF]
Physical Review D, 2008 The study of extragalactic sources of high energy radiation via the direct measurement of the proton and neutrino fluxes that they are likely to emit is one of the main goals for the future observations of the recently developed air showers detectors and neutrino telescopes. In this work we discuss the relation between the inclusive proton and neutrino

Extragalactic Stellar Astronomy [PDF]
Thirty Years of Astronomical Discovery With UKIRT, 2008 Despite their paucity, massive hot stars are real cosmic engines of fundamental importance in shaping our Universe, from its very early stages up to its current appearance. Understanding the physics of massive stars is then a key issue for many relevant astrophysical phenomena.

The Herschel–SPIRE instrument and its capabilities for extragalactic astronomy
Advances in Space Research, 2007 SPIRE, the Spectral and Photometric Imaging Receiver, is one of three instruments to fly on the European Space Agency’s Herschel Space Observatory. It contains a three-band imaging photometer operating at 250, 350 and 500 μm, and an imaging Fourier transform spectrometer covering 194–672 μm. The SPIRE detectors are arrays of feedhorn-coupled bolometers

How Are Red and Blue Quasars Different? The Radio Properties
Galaxies, 2021 A non-negligible fraction of quasars are red at optical wavelengths, indicating (in the majority of cases) that the accretion disc is obscured by a column of dust which extinguishes the shorter-wavelength blue emission. In this paper, we summarize recent
