Dissecting the active galactic nucleus in Circinus IV. MUSE NFM observations unveil a tuning-fork ionised gas morphology
D. Kakkad, M. Stalevski, M. Kishimoto +3
We present the ionised gas outflow morphology in the Circinus galaxy using the Narrow Field Mode (NFM) of the MUSE instrument on board the Very Large Telescope (VLT). The NFM obser…
The Black Hole-Galaxy Connection: Interplay between Feedback, Obscuration, and Host Galaxy Substructure
Stéphanie Juneau, Andy D. Goulding, Julie Banfield +20
There is growing evidence for physical influence between supermassive black holes and their host galaxies. We present a case study of nearby galaxy NGC 7582, for which we find evid…
The Next Generation Fornax Survey (NGFS): VII. A MUSE view of the nuclear star clusters in Fornax dwarf galaxies
Evelyn J. Johnston, Thomas H. Puzia, Giuseppe D'Ago +16
Clues to the formation and evolution of Nuclear Star Clusters (NSCs) lie in their stellar populations. However, these structures are often very faint compared to their host galaxy,…
Evolution of compact groups from intermediate to final stages: A case study of the HI content of HCG 16
Michael G. Jones, Lourdes Verdes-Montenegro, Ancor Damas-Segovia +13
Hickson Compact Group (HCG) 16 is a prototypical compact group of galaxies, apparently in an intermediate stage of evolution, where its galaxies are losing gas to the intra-group m…
Discovery of a Damped Ly-alpha System in a Low-z Galaxy Group: Possible Evidence for Gas Inflow and Nuclear Star Formation
Sanchayeeta Borthakur, Emmanuel Momjian, Timothy M. Heckman +3
We present a low-redshift (z=0.029) Damped Lyman-alpha (DLA) system in the spectrum of a background Quasi-Stellar Object (QSO). The DLA is associated with an interacting galaxy pai…
Calibrating Interstellar Abundances using SNR Radiative Shocks
Michael A. Dopita, Ivo R. Seitenzahl, Ralph S. Sutherland +4
Using integral field data we extract the optical spectra of shocked interstellar clouds in Kepler's supernova remnant located in the inner regions of our Galaxy, as well as in the…
Shocked Interstellar clouds and dust grain destruction in the LMC Supernova Remnant N132D
Michael A. Dopita, Frédéric P. A. Vogt, Ralph S. Sutherland +3
From integral field data we extract the optical spectra of 20 shocked clouds in the supernova remnant N132D in the Large Magellanic Cloud (LMC). Using self-consistent shock modelli…
Integral Field Spectroscopy of Supernova Remnant 1E0102-7219 Reveals Fast-moving Hydrogen and Sulfur-rich Ejecta
Ivo R. Seitenzahl, Fredéric P. A. Vogt, Jason P. Terry +4
We study the optical emission from heavy element ejecta in the oxygen-rich young supernova remnant (SNR) 1E 0102.2-7219 (1E 0102) in the Small Magellanic Cloud. We have used the Mu…
MUSE Integral Field Observations of the Oxygen-rich SNR 1E 0102.2-7219
Ivo R. Seitenzahl, Frédéric P. A. Vogt, Jason P. Terry +4
We have observed the oxygen-rich SNR 1E 0102.2-7219 with the integral field spectrograph WiFeS at Siding Spring Observatory and discovered sulfur-rich ejecta for the first time. Fo…
Forbidden Iron Lines and Dust Destruction in Supernova Remnant Shocks: The Case of N49 in the Large Magellanic Cloud
Michael A. Dopita, Ivo R. Seitenzahl, Ralph S. Sutherland +3
We present results of a complete integral field survey of the bright SNR N49 in the LMC, obtained with the WiFeS instrument mounted on the ANU 2.3m telescope at Siding Spring Obser…
The physics and kinematics of the evolved, interacting planetary nebula PN G342.0-01.7
Alaa Ali, Morsi A. Amer, M. A. Dopita +2
Here we aim to study the physical and kinematical characteristics of the unstudied old planetary nebula (PN) PN G342.0-01.7, which shows evidence of interaction with its surroundin…
Galaxy Interactions in Compact Groups II: abundance and kinematic anomalies in HCG 91c
F. P. A. Vogt, M. A. Dopita, S. Borthakur +4
Galaxies in Hickson Compact Group 91 (HCG 91) were observed with the WiFeS integral field spectrograph as part of our ongoing campaign targeting the ionized gas physics and kinemat…
Dissecting galactic bulges in space and time I: the importance of early formation scenarios vs. secular evolution
M. K. Seidel, R. Cacho, T. Ruiz-Lara +7
The details of bulge formation via collapse, mergers, secular processes or their interplay remain unresolved. To start answering this question and quantify the importance of distin…
IZI: Inferring the Gas Phase Metallicity (Z) and Ionization Parameter (q) of Ionized Nebulae using Bayesian Statistics
Guillermo A. Blanc, Lisa Kewley, Frédéric P. A. Vogt +1
We present a new method for inferring the metallicity (Z) and ionization parameter (q) of HII regions and star-forming galaxies using strong nebular emission lines (SEL). We use Ba…
Galaxy emission line classification using 3D line ratio diagrams
Frédéric P. A. Vogt, Michael A. Dopita, Lisa J. Kewley +5
