AGN Zoo and Classications of Active Galaxies

We review the variety of Active Galactic Nuclei (AGN) classes (so-calledAGN zoo") and classification schemes of galaxies by activity types based on their optical emission-line spectrum, as well as other parameters and other than optical wave-length ranges. A historical overview of discoveries of various types of active galaxies is given, including Seyfert galaxies, radio galaxies, QSOs, BL Lace...

Compact radio jets and nuclear regions in active galaxies

VLBI observations of relativistic outflows (jets) in galactic nuclei, complemented with detailed studies made in other spectral domains, have become an effective tool for investigating the physics of nuclear regions in galaxies. High-resolution radio observations access directly the regions where the jets are formed, and trace their evolution and interaction with the nuclear environment. The em...

Reference Deconvolution: A Simple and Effective Method for Resolution Enhancement in Nuclear Magnetic Resonance Spectroscopy

Linewidths and line shapes are key criteria determining the utility of a ( ) nuclear magnetic resonance NMR spectrum, and considerable effort is usually devoted to ( ) shimming the magnetic field B to ensure optimum resolution. However, even if the 0 external field is almost perfectly homogeneous, the sample itself can induce gradients owing to susceptibility effects from its overall shape or i...

passivity in waiting for godot and endgame: a psychoanalytic reading

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...

A method for spatial deconvolution of spectra

A method for spatial deconvolution of spectra is presented. It follows the same fundamental principles as the “MCS image deconvolution algorithm” (Magain, Courbin, Sohy, 1998) and uses information contained in the spectrum of a reference Point Spread Function (PSF) to spatially deconvolve spectra of very blended sources. An improved resolution rather than an infinite one is aimed at, overcoming...
