Gemini IFU, VLA and HST observations of the OH Megamaser galaxy IRASF23199+0123: the hidden monster and its outflow
Carpes Hekatelyne, Rogemar A. Riffel, Dinalva Sales +6
We present Gemini Multi-Object Spectrograph (GMOS) Integral field Unit (IFU), Very Large Array (VLA) and Hubble Space Telescope (HST) observations of the OH Megamaser (OHM) galaxy…
A candidate sub-parsec binary black hole in the Seyfert galaxy NGC 7674
Preeti Kharb, Dharam Vir Lal, David Merritt
The existence of binary supermassive black holes (SBHs) is predicted by models of hierarchical galaxy formation. To date, only a single binary SBH has been imaged, at a projected s…
Probing the Physics of Narrow Line Regions in Active Galaxies IV: Full data release of The Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7)
Adam D. Thomas, Michael A. Dopita, Prajval Shastri +15
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 fi…
Dual Active Galactic Nuclei in Nearby Galaxies
M. Das, K. Rubinur, P. Kharb +3
Galaxy mergers play a crucial role in the formation of massive galaxies and the buildup of their bulges. An important aspect of the merging process is the in-spiral of the supermas…
Double-Peaked Emission Lines due to A Radio Outflow in KISSR1219
P. Kharb, S. Subramanian, S. Vaddi +2
We present the results from 1.5 and 5 GHz phase-referenced VLBA and 1.5 GHz Karl G. Jansky Very Large Array (VLA) observations of the Seyfert 2 galaxy KISSR1219, which exhibits dou…
Dissecting Galaxies: Separating Star Formation, Shock Excitation and AGN Activity in the Central Region of NGC 613
Rebecca L. Davies, Brent Groves, Lisa J. Kewley +13
The most rapidly evolving regions of galaxies often display complex optical spectra with emission lines excited by massive stars, shocks and accretion onto supermassive black holes…
