  • Dissecting galaxies: separating star formation, shock excitation and AGN activity in the central region of NGC 613 
    Davies, R. L; Groves, B; Kewley, L. J; Medling, A. M; Shastri, P; Maithil, J; Kharb, P; Banfield, J; Longbottom, F; Dopita, M. A; Hampton, E. J; Scharwachter, J; Sutherland, R; Jin, C; Zaw, I; Juneau, S (Oxford University Press on behalf of the Royal Astronomical Society, 2017-08)
    The most rapidly evolving regions of galaxies often display complex optical spectra with emission lines excited by massive stars, shocks and accretion on to supermassive black holes. Standard calibrations (such as for ...
  • Probing the physics of narrow-line regions of Seyfert galaxies, I. The case of NGC 5427 
    Dopita, M. A; Scharwachter, J; Shastri, P; Kewley, L. J; Davies, R; Sutherland, R; Kharb, P; Jose, J; Hampton, E; Jin, C; Banfield, J; Basurah, H; Fischer, S (EDP Sciences, 2014-06)
    Context. The spectra of the extended narrow-line regions (ENLRs) of Seyfert 2 galaxies probe the physics of the central active galaxy nucleus (AGN), since they encode the energy distribution of the ionising photons, the ...
  • S7 : Probing the physics of seyfert galaxies through their ENLR & HII regions 
    Dopita, M. A; Shastri, P; Scharwachter, J; Kewley, L. J; Davies, R; Sutherland, R; Kharb, P; Jose, Jessy; Bhatt, H. C; Ramya, S; Hamptona, E; Jina, C; Banfielda, J; Zawa, I; Srivastavaa, Shweta; Jamesa, B (Cambridge University Press, 2015-02)
    Here we present the first results from the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) which aims to investigate the physics of ∼140 radio-detected southern active Galaxies with z<0.02 through Integral ...
