Statistical multifrequency study of narrow-line Seyfert 1 galaxies
Emilia Järvelä, Anne Lähteenmäki, Jonathan León-Tavares
High-energy γ-rays, which are produced by powerful relativistic jets, are usually associated with blazars and radio galaxies. In the current active galactic nuclei (AGN) paradigm,…
