H II region filling factors in NGC 628: Luminosity-size relation and connection with polycyclic aromatic hydrocarbon emission
Lorena Aragüete Riesco, José M. Vílchez, Salvador Duarte Puertas +7
Understanding the internal structure of H II regions is fundamental for constraining star formation processes in galaxies. We investigated how the filling factor (FF) relates to lu…
SIGNALS of Giant HII Regions: A Spatially Resolved Analysis of NGC 604
Ray Garner, Robert C. Kennicutt, Laurent Drissen +6
Observing giant HII regions at fine spatial scales uncovers detailed structures and reveals variations in ionization, abundance, and dynamical properties of ionized gas and the eff…
Ionized gas in NGC 4258: Exploring the AGN -- Star formation connection
D. Fernández-Arenas, L. Rousseau-Nepton, C. Robert +9
NGC 4258 is a prime target for studying feedback in Low-Luminosity Active Galactic Nuclei (LLAGNs) due to its proximity and comprehensive multi-wavelength coverage. Using new Integ…
The planetary nebula NGC 3132 revisited: high definition 3D photoionization model
H. Monteiro, C. Mendes de Oliveira, P. Amram +6
We present a detailed 3D photoionization model of the planetary nebula NGC 3132, constrained by the latest observations. Using the MOCASSIN code, the model incorporates integrated…
SIGNALS on the mixing of oxygen and nitrogen in the spiral galaxy NGC 6946
Fabio Bresolin, David Fernández-Arenas, Laurie Rousseau-Nepton +10
As part of the SIGNALS survey, which comprises a sample of approximately 40 nearby galaxies observed with the Fourier transform spectrometer SITELLE, we present a study of metal mi…
NGC 628 in SIGNALS: Explaining the Abundance-Ionization Correlation in HII Regions
Ray Garner, Robert Kennicutt, Laurie Rousseau-Nepton +5
The variations of oxygen abundance and ionization parameter in HII regions are usually thought to be the dominant factors that produced variations seen in observed emission line sp…
Properties of supernova remnants in SIGNALS galaxies -- I . NGC 6822 and M33
Salvador Duarte Puertas, Laurent Drissen, Carmelle Robert +4
We present a spatially resolved study of the kinematical properties of known supernova remnants (SNRs) in the nearest galaxies of the SIGNALS survey, namely NGC 6822 (one object) a…
Planetary Nebula NGC 2818: Revealing its complex 3D morphology
Sophia Derlopa, Stavros Akras, Philippe Amram +3
We carry out an advanced morpho-kinematic analysis of the Planetary Nebula (PN) NGC 2818, whose complex morphology is described by a basic bipolar component, filamentary structures…
Ring nebulae around Wolf-Rayet stars in M33 as seen by SITELLE
Selin Tuquet, Nicole St. -Louis, Laurent Drissen +5
We have conducted an analysis of nebulae around Wolf-Rayet (WR) stars in M33 using data collected by the imaging Fourier transform spectrometer SITELLE at the Canada-France-Hawaii…
SIGNALS: I. Survey Description
L. Rousseau-Nepton, R. P. Martin, C. Robert +60
SIGNALS, the Star formation, Ionized Gas, and Nebular Abundances Legacy Survey, is a large observing program designed to investigate massive star formation and HII regions in a sam…
Probing the nature of the pre-merging system Hickson Compact Group 31 through IFU data
M. Alfaro-Cuello, S. Torres-Flores, E. R. Carrasco +3
We present a study of the kinematics and the physical properties of the central region of the Hickson Compact Group 31 (HCG 31), focusing on the HCG 31A+C system, using integral fi…
