Aims: We present an analysis of a galaxy (SAGE1CJ053634.78-722658.5) at a redshift of 0.14 of which the infrared (IR) emission is entirely dominated by emission associated with the active galactic nucleus. Methods: We present the 5-37 ЮМm Spitzer/IRS spectrum and broad wavelength spectral energy distribution (SED) of SAGE1CJ053634.78-722658.5, an IR point-source detected by Spitzer/SAGE. ... We compare the source with models of emission from dusty tori around AGNs. ...

... The Sun of our solar system is a typical star of intermediate size and luminosity. ... The Sun has a very complex surface magnetic field created by convective flow of the electrically conducting solar material. ... The escaping hot coronal plasma is called the solar wind . ...

... The Sun is the closest star to us, and a regular object in our Galaxy. Solar activity manifests itself, primarily, in solar flares - episodic explosive energy release in the form of electromagnetic radiation and high energy particles (electrons and protons). The nature of the flares is related to cyclic variations of global and local magnetic fields in the atmosphere of the Sun. ... Such formations are called active regions. ...
