The ALMaQUEST Survey: III. Scatter in the resolved star forming main sequence is primarily due to variations in star formation efficiency
Sara L. Ellison, Mallory D. Thorp, Lihwai Lin +6
Using a sample of 11,478 spaxels in 34 galaxies with molecular gas, star formation and stellar maps taken from the ALMA-MaNGA QUEnching and STar formation (ALMaQUEST) survey, we in…
Are galactic star formation and quenching governed by local, global or environmental phenomena?
Asa F. L. Bluck, Roberto Maiolino, Sebastian Sanchez +5
We present an analysis of star formation and quenching in the SDSS-IV MaNGA-DR15, utilising over 5 million spaxels from 3500 local galaxies. We estimate star formation rate s…
Deep learning predictions of galaxy merger stage and the importance of observational realism
Connor Bottrell, Maan H. Hani, Hossen Teimoorinia +7
Machine learning is becoming a popular tool to quantify galaxy morphologies and identify mergers. However, this technique relies on using an appropriate set of training data to be…
LRP2020: Machine Learning Advantages in Canadian Astrophysics
K. A. Venn, S. Fabbro, A Liu +12
The application of machine learning (ML) methods to the analysis of astrophysical datasets is on the rise, particularly as the computing power and complex algorithms become more po…
Dwarfs or giants? Stellar metallicities and distances in the Canada-France-Imaging-Survey from multi-band photometry
Guillaume F. Thomas, Nicholaas Annau, Alan McConnachie +19
We present a new fully data-driven algorithm that uses photometric data from the Canada-France-Imaging-Survey (CFIS; ), Pan-STARRS 1 (PS1; ), and Gaia () to discriminat…
CLOVER: Convnet Line-fitting Of Velocities in Emission-line Regions
Jared Keown, James Di Francesco, Hossen Teimoorinia +2
When multiple star-forming gas structures overlap along the line-of-sight and emit optically thin emission at significantly different radial velocities, the emission can become non…
What shapes a galaxy? - Unraveling the role of mass, environment and star formation in forming galactic structure
Asa F. L. Bluck, Connor Bottrell, Hossen Teimoorinia +9
We investigate the dependence of galaxy structure on a variety of galactic and environmental parameters for ~500,000 galaxies at z<0.2, taken from the Sloan Digital Sky Survey data…
