VLBI Imaging of the Double Peaked Emission Line Seyfert KISSR1494
Preeti Kharb, Mousumi Das, Zsolt Paragi +2
We present here the results from dual-frequency phase-referenced VLBI observations of the Seyfert galaxy KISSR1494, which exhibits double peaked emission lines in its SDSS spectrum…
Understanding Jets from Sources Straddling the Fanaroff-Riley Divide
Preeti Kharb, Ethan Stanley, Matthew Lister +3
Results from Chandra-HST-VLA observations of 13 hybrid sources are presented. Data from ten sources in the literature are analysed along with new data from three hybrid blazars bel…
An embedded active nucleus in the OH megamaser galaxy IRAS16399-0937
Dinalva A. Sales, A. Robinson, D. J. Axon +7
We present a multiwavelength study of the OH Megamaser galaxy (OHMG) IRAS16399-0937, based on new HST/ACS F814W and H+[NII] images and archive data from HST, 2MASS, Spitzer, Her…
Kiloparsec-scale radio emission in Seyfert and LINER galaxies
Veeresh Singh, C. H. Ishwara-Chandra, Yogesh Wadadekar +2
Seyfert and LINER galaxies are known to exhibit compact radio emission on 10 to 100 parsec scales, but larger Kiloparsec-Scale Radio structures (KSRs) often remain undetecte…
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…
Probing the Active Massive Black Hole Candidate in the Center of NGC 404 with VLBI
Z. Paragi, S. Frey, P. Kaaret +3
Recently Nyland et al. (2012) argued that the radio emission observed in the center of the dwarf galaxy NGC 404 originates in a low-luminosity active galactic nucleus (LLAGN) power…
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…
Probing Radio Emission in Seyfert Galaxies on Parsec- and Kiloparsec-scales
P. Kharb, V. Singh, J. F. Gallimore +1
Seyfert galaxies have traditionally been classified as radio-quiet active galactic nuclei. A proper consideration of the nuclear optical emission however proves that a majority of…
VLBA Observations of Mrk 6: Probing the Jet-Lobe Connection
P. Kharb, C. P. O'Dea, S. A. Baum +5
We present the results of high resolution VLBI observations at 1.6 and 4.9 GHz of the radio-loud Seyfert galaxy, Mrk 6. These observations are able to detect a compact radio core i…
