Astronomical Image Quality Prediction based on Environmental and Telescope Operating Conditions
Sankalp Gilda, Yuan-Sen Ting, Kanoa Withington +6
Intelligent scheduling of the sequence of scientific exposures taken at ground-based astronomical observatories is massively challenging. Observing time is over-subscribed and atmo…
Machine Learning Approach to Integral Field Unit Spectroscopy Observations: I. HII Region Kinematics
Carter L. Rhea, Laurie Rousseau-Nepton, Simon Prunet +2
SITELLE is a novel integral field unit spectroscopy instrument that has an impressive spatial (11 by 11 arcmin), spectral coverage, and spectral resolution (R=1-20000). SIGNALS is…
When do cosmic peaks, filaments or walls merge? A theory of critical events in a multi-scale landscape
Corentin Cadiou, Christophe Pichon, Sandrine Codis +5
The merging rate of cosmic structures is computed, relying on the Ansatz that they can be predicted in the initial linear density field from the coalescence of critical points with…
Wide field-of-view study of the Eagle Nebula with the Fourier transform imaging spectrograph SITELLE at CFHT
Nicolas Flagey, Anna F. McLeod, Laura Aguilar +1
We present the very first wide-field, 11 by 11 arcmin, optical spectral mapping of M16, one of the most famous star-forming regions in the Galaxy. The data were acquired with the n…
