Deep Learning for Morphological Identification of Extended Radio Galaxies using Weak Labels

1 code implementation9 Aug 2023 Nikhel Gupta, Zeeshan Hayder, Ray P. Norris, Minh Huynh, Lars Petersson, X. Rosalind Wang, Heinz Andernach, Bärbel S. Koribalski, Miranda Yew, Evan J. Crawford

The CAMs are further refined using an inter-pixel relations network (IRNet) to get instance segmentation masks over radio galaxies and the positions of their infrared hosts.

AlFoCS + F3D II: unexpectedly low gas-to-dust ratios in the Fornax galaxy cluster

no code implementations3 Feb 2021 Nikki Zabel, Timothy A. Davis, Matthew W. L. Smith, Marc Sarzi, Alessandro Loni, Paolo Serra, Maritza A. Lara-López, Phil Cigan, Maarten Baes, George J. Bendo, Ilse De Looze, Enrichetta Iodice, Dane Kleiner, Bärbel S. Koribalski, Reynier Peletier, Francesca Pinna, P. Tim de Zeeuw

This implies that a relatively large fraction of the metals in these Fornax systems is locked up in dust, which is possibly due to altered chemical evolution as a result of the dense environment.

2D Bayesian automated tilted-ring fitting of disk galaxies in large HI galaxy surveys: 2DBAT

2 code implementations7 Sep 2017 Se-Heon Oh, Lister Staveley-Smith, Kristine Spekkens, Peter Kamphuis, Bärbel S. Koribalski

We present a novel algorithm based on a Bayesian method for 2D tilted-ring analysis of disk galaxy velocity fields.
