    • Dissecting the active galactic nucleus in Circinus - I. Peculiar mid-IR morphology explained by a dusty hollow cone 
      Stalevski, Marko; Asmus, Daniel; Tristram, Konrad R. W. (Oxford university press, 2017)
      Recent high angular resolution observations resolved for the first time the mid-infrared (MIR) structure of nearby active galactic nuclei (AGN). Surprisingly, they revealed that a major fraction of their MIR emission comes ...
    • Evidence for Periodicity in 43 Year-Long Monitoring of NGC 5548 
      Bon, Edi; Zucker, S.; Netzer, H.; Marziani, Paola; Bon, N.; Jovanovic, Predrag; Shapovalova, A. I.; Komossa, S.; Gaskell, C. M.; Popović, Ljiljana; Britzen, Stefan; Chavushyan, V. H.; Burenkov, A.; Sergeev, S. G.; La Mura, Giovanni; Valdés, J. R.; Stalevski, Marko (IOP, 2016)
      We present an analysis of 43 years (1972 to 2015) of spectroscopic observations of the Seyfert 1 galaxy NGC 5548. This includes 12 years of new unpublished observations (2003 to 2015). We compiled about 1600 H beta spectra ...
    • Polarization in Monte Carlo radiative transfer and dust scattering polarization signatures of spiral galaxies 
      Peest, C.; Camps, P.; Stalevski, Marko; Baes, M.; Siebenmorgen, R. (EDP Sciences, 2017-05)
      Polarization is an important tool to further the understanding of interstellar dust and the sources behind it. In this paper we describe our implementation of polarization that is due to scattering of light by spherical ...
    • The dust covering factor in active galactic nuclei 
      Stalevski, Marko; Ricci, Claudio; Ueda, Yoshihiro; Lira Teillery, Paulina; Fritz, Jacopo; Baes, Maarten (Oxford Univ Press, 2016)
      The primary source of emission of active galactic nuclei (AGNs), the accretion disc, is surrounded by an optically and geometrically thick dusty structure ('the so-called dusty torus'). The infrared radiation emitted by ...
