A low-luminosity type-1 QSO sample: II. Tracing circumnuclear star formation in HE 1029-1831 with SINFONI
Gerold Busch, Semir Smajić, Julia Scharwächter +6
Circumnuclear star formation and AGN feedback is believed to play a critical role in the context of galaxy evolution. The low-luminosity QSO (LLQSO) sample that contains 99 of the…
S7 : Probing the physics of Seyfert Galaxies through their ENLR & HII Regions
Michael A. Dopita, Prajval Shastri, Julia Scharwachter +13
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 a…
Galaxy emission line classification using 3D line ratio diagrams
Frédéric P. A. Vogt, Michael A. Dopita, Lisa J. Kewley +5
Two-dimensional (2D) line ratio diagnostic diagrams have become a key tool in understanding the excitation mechanisms of galaxies. The curves used to separate the different regions…
Probing the physics of narrow-line regions of Seyfert galaxies I: The case of NGC 5427
Michael A. Dopita, Julia Scharwaechter, Prajval Shastri +10
We have used the Wide Field Spectrograph (WiFeS) on the ANU 2.3m telescope at Siding Spring to observe the nearby, nearly face-on, Seyfert 2 galaxy, NGC 5427. We have obtained inte…
