  • Probing the physics of narrow line regions in active galaxies. II. the siding spring southern seyfert spectroscopic snapshot survey (S7) 
    Dopita, M. A; Shastri, P; Davies, R; Kewley, L; Hampton, E; Scharwachter, J; Sutherland, R; Kharb, P; Jose, J; Bhatt, H. C; Ramya, S; Jin, C; Banfield, J; Zaw, I; Juneau, S; James, B; Shweta Srivastava (IOP Publishing, 2015-03)
    Here we describe the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) and present results on 64 galaxies drawn from the first data release. The S7 uses the Wide Field Spectrograph mounted on the ANU 2.3 m ...
  • 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 Narrow-line Regions in Active Galaxies. IV. Full Data Release of the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) 
    Thomas, A. D; Dopita, M. A; Shastri, P; Davies, R; Hampton, E; Kewley, L; Banfield, J; Groves, B; James, B. L; Jin, C; Juneau, S; Kharb, P; Lalitha, S; Scharwachter, J; Shalima, P; Sundar, M. N; Sutherland, R; Zaw, I (IOP Publishing, 2017-09)
    We present the second and final data release of the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7). Data are presented for 63 new galaxies not included in the first data release, and we provide 2D ...
  • 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 ...
  • Using an artificial neural network to classify multicomponent emission lines with integral field spectroscopy from SAMI and S7 
    Hampton, E. J; Medling, A. M; Groves, B; Kewley, L; Dopita, M; Davies, R; Ho, I-Ting; Kaasinen, M; Leslie, S; Sharp, R; Sweet, S. M; Thomas, A. (Oxford University Press on behalf of the Royal Astronomical Society, 2017-09)
    Integral field spectroscopy (IFS) surveys are changing how we study galaxies and are creating vastly more spectroscopic data available than before. The large number of resulting spectra makes visual inspection of emission ...
