  • Probing the physics of narrow-line regions in active galaxies. III. accretion and cocoon shocks in the liner NGC 1052 
    Dopita, M. A; Ho, I-Ting; Dressel, L. L; Sutherland, R; Kewley, L; Davies, R; Hampton, E; Shastri, P; Kharb, P; Jose, Jessy; Bhatt, H. C; Ramya, S; Scharwachter, J; Jin, C; Banfield, J; Zaw, I; James, B; Juneau, S; Srivastava, S (IOP Publishing, 2015-03-01)
    We present Wide Field Spectrograph integral field spectroscopy and Hubble Space Telescope Faint Object Spectrograph spectroscopy for the low-ionization nuclear emission line region (LINER) galaxy NGC 1052. We infer the ...
  • Probing the physics of Seyfert galaxies using their emission-line regions 
    Shastri, P; Dopita, M; Scharwachter, J; Kewley, L; Davies, R; Sutherland, R; Kharb, P; Banfield, J; Jose, J; Ramya, S; Srivastava, S; Bhatt, H. C; Hampton, E; Jin, J; Basurah, H; Fischer, S; Gupta, M; Panda, S; Sundar, M. N; Radhakrishnan, V (AIP Publishing, 2015-12)
    Active galaxies have powerhouses of radiation in their nuclear regions that are driven by accreting super-massive black holes. The accretion system also generates outflows of ionized gas and synchrotron-emitting bipolar ...
  • The role of radiation pressure in the narrow line regions of Seyfert host galaxies 
    Davies, R. L; Dopita, M. A; Kewley, L; Groves, B; Sutherland, R; Hampton, E. J; Shastri, P; Kharb, P; Bhatt, H. C; Scharwachter, J; Jin, C; Banfield, J; Zaw, I; James, B; Juneau, S; Srivastava, S (IOP Publishing, 2016-06-10)
    We investigate the relative significance of radiation pressure and gas pressure in the extended narrow line regions (ENLRs) of four Seyfert galaxies from the integral field Siding Spring Southern Seyfert Spectroscopic ...
