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…
Integral field spectroscopy and numerical simulations of the NGC 2207/IC 2163 system
Camille Poitras, René Pierre Martin, Laurent Drissen +2
We present integral field spectroscopy of the interacting galaxy system NGC 2207/IC 2163 obtained with the imaging Fourier Transform Spectrometer SITELLE. Approximately 1000 HII re…
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…
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…
