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…
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…
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…
WISDOM project -- XXIII. Star-formation efficiencies of eight early-type galaxies and bulges observed with SITELLE and ALMA
Anan Lu, Daryl Haggard, Martin Bureau +18
Early-type galaxies (ETGs) are known to harbour dense spheroids of stars with scarce star formation (SF). Approximately a quarter of these galaxies have rich molecular gas reservoi…
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…
Characterization of M51 supernova remnants with the imaging spectrometer SITELLE
Billy Gamache, Laurent Drissen, Carmelle Robert +1
We present preliminary results of a detailed 3D study of supernova remnants in the nearby spiral M51 using data from the SIGNALS survey obtained with the imaging Fourier transform…
