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…
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…
A Machine Learning Approach to Integral Field Unit Spectroscopy Observations: III. Disentangling Multiple Components in Hii regions
Carter Lee Rhea, Laurie Rousseau-Nepton, Simon Prunet +7
In the first two papers of this series (Rhea et al. 2020; Rhea et al. 2021), we demonstrated the dynamism of machine learning applied to optical spectral analysis by using neural n…
O CAESAR: The Optical CAtalogue of Extragalactic SupernovA Remnants
I. Moumen, C. Robert, D. Devost +6
We present O CAESAR, the Optical CAtalogue of Extragalactic SupernovA Remnants. O CAESAR will provide the largest homogeneous optical survey of extragalactic SNR candidates taken b…
Elemental abundances in the center of the Galactic Nuclear Disc
V. V. Kovtyukh, S. M. Andrievsky, R. P. Martin +5
We have made the first attempt to derive the chemical properties of the Galactic disc at its very central part using high-resolution infrared spectroscopic observations of four cla…
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…
3D Optical Spectroscopic Study of NGC3344 with SITELLE: I. Identification and Confirmation of Supernova Remnants
Ismael Moumen, Carmelle Robert, Daniel Devost +4
We present the first optical identification and confirmation of a sample of supernova remnants (SNRs) in the nearby galaxy NGC3344. Using high spectral and spatial resolution data,…
SITELLE: An Imaging Fourier Transform Spectrometer for the Canada-France-Hawaii Telescope
Laurent Drissen, Thomas Martin, Laurie Rousseau-Nepton +11
We present an overview of SITELLE, an Imaging Fourier Transform Spectrometer (iFTS) available at the 3.6-meter Canada-France-Hawaii Telescope. SITELLE is a Michelson-type interfero…
NGC628 with SITELLE : I. Imaging Spectroscopy of 4285 HII region candidates
Laurie Rousseau-Nepton, Carmelle Robert, Laurent Drissen +2
This is the first paper of a series dedicated to nebular physics and the chemical evolution of nearby galaxies by investigating large samples of HII regions with the CFHT imaging s…
Oxygen, -element and iron abundance distributions in the inner part of the Galactic thin disc. II
S. M. Andrievsky, R. P. Martin, V. V. Kovtyukh +2
We have derived the abundances of 36 chemical elements in one Cepheid star, ASAS 181024--2049.6, located R kpc from the Galactic center. This star falls within a re…
Oxygen, α-element and iron abundance distributions in the inner part of the Galactic thin disc
R. P. Martin, S. M. Andrievsky, V. V. Kovtyukh +3
We derived elemental abundances in 27 Cepheids, the great majority situated within a zone of Galactocentric distances ranging from 5 to 7 kpc. One star of our sample, SU Sct, has a…
