Faceting for direction-dependent spectral deconvolution
C. Tasse, B. Hugo, M. Mirmont +7
The new generation of radio interferometers is characterized by high sensitivity, wide fields of view and large fractional bandwidth. To synthesize the deepest images enabled by th…
Painting galaxies into dark matter halos using machine learning
Shankar Agarwal, Romeel Davé, Bruce A. Bassett
We develop a machine learning (ML) framework to populate large dark matter-only simulations with baryonic galaxies. Our ML framework takes input halo properties including halo mass…
The jet/wind outflow in Centaurus A: a local laboratory for AGN feedback
B. McKinley, S. J. Tingay, E. Carretti +20
We present new radio and optical images of the nearest radio galaxy Centaurus A and its host galaxy NGC 5128. We focus our investigation on the northern transition region, where en…
Statistical 21-cm Signal Separation via Gaussian Process Regression Analysis
F. G. Mertens, A. Ghosh, L. V. E. Koopmans
Detecting and characterizing the Epoch of Reionization and Cosmic Dawn via the redshifted 21-cm hyperfine line of neutral hydrogen will revolutionize the study of the formation of…
Detection of Bars in Galaxies using a Deep Convolutional Neural Network
Sheelu Abraham, Arun Aniyan, Ajit K. Kembhavi +2
We present an automated method for the detection of bar structure in optical images of galaxies using a deep convolutional neural network which is easy to use and provides good acc…
Model-independent curvature determination with 21cm intensity mapping experiments
Amadeus Witzemann, Philip Bull, Chris Clarkson +3
Recent precision cosmological parameter constraints imply that the spatial curvature of the Universe is essentially dynamically negligible - but only if relatively strong assumptio…
