Unveiling a cosmic tango: Integral field spectroscopy and numerical simulations of Arp 143's interaction
Hugo Martel, Carmelle Robert, Laurent Drissen +6
We present spectral data cubes of the interacting galaxy system Arp 143, composed of the ring galaxy NGC 2445 and the lenticular galaxy NGC 2444, obtained with the imaging Fourier…
An automated method for planetary nebula detection with SIGNALS: first applications to NGC 4214 and NGC 4449
Nancy Yang, Johanna Hartke, Martin Bureau +11
Utilising the optical imaging Fourier transform spectrograph SITELLE, the Star-formation, Ionized Gas and Nebular Abundances Legacy Survey (SIGNALS) is designed to study the connec…
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…
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…
