Revisiting AGN Placement on the BPT Diagram: A Spectral Decomposition Approach
Hossen Teimoorinia, Sara Shishehchi, Finn Archinuk +5
Traditional single-fibre spectroscopy provides a single galaxy spectrum, forming the basis for crucial parameter estimation. However, its accuracy can be compromised by various sou…
Stellar Populations With Optical Spectra: Deep Learning vs. Popular Spectrum Fitting Codes
Joanna Woo, Dan Walters, Finn Archinuk +4
We compare the performance of several popular spectrum fitting codes (Firefly, starlight, pyPipe3D and pPXF), and a deep-learning convolutional neural network (StarNet), in recover…
Mapping the Diversity of Galaxy Spectra with Deep Unsupervised Machine Learning
Hossen Teimoorinia, Finn Archinuk, Joanna Woo +2
Modern spectroscopic surveys of galaxies such as MaNGA consist of millions of diverse spectra covering different regions of thousands of galaxies. We propose and implement a deep u…
Forecasting Wavefront Corrections in an Adaptive Optics System
Rehan Hafeez, Finn Archinuk, Sébastien Fabbro +2
We use telemetry data from the Gemini North ALTAIR adaptive optics system to investigate how well the commands for wavefront correction (both Tip/Tilt and high-order turbulence) ca…
Pattern recognition in the ALFALFA.70 and Sloan Digital Sky Surveys: A catalog of 500,000 HI gas fraction estimates based on artificial neural networks
Hossen Teimoorinia, Sara L. Ellison, David R. Patton
The application of artificial neural networks (ANNs) for the estimation of HI gas mass fraction (\fgas) is investigated, based on a sample of 13,674 galaxies in the Sloan Digital S…
The impact of galactic properties and environment on the quenching of central and satellite galaxies: A comparison between SDSS, Illustris and L-Galaxies
Asa F. L. Bluck, J. Trevor Mendel, Sara L. Ellison +7
We quantify the impact that a variety of galactic and environmental properties have on the quenching of star formation. We collate a sample of 400,000 central and 100…
