Observationally derived change in the star formation rate as mergers progress
W. J. Pearson, L. Wang, V. Rodriguez-Gomez +2
Galaxy mergers can change the rate at which stars are formed. We can trace when these changes occur in simulations of galaxy mergers. However, for observed galaxies we do not know…
Galaxy mergers classification using CNNs trained on Sérsic models, residuals and raw images
D. M. Chudy, W. J. Pearson, A. Pollo +5
Galaxy mergers are crucial for understanding galaxy evolution, and with large upcoming datasets, automated methods such as Convolutional Neural Networks (CNNs) are essential for ef…
Effects of galaxy environment on merger fraction
W. J. Pearson, D. J. D. Santos, T. Goto +13
Aims. In this work, we intend to examine how environment influences the merger fraction, from the low density field environment to higher density groups and clusters. We also aim t…
Do galaxy mergers prefer under-dense environments?
U. Sureshkumar, A. Durkalec, A. Pollo +6
Galaxy mergers play a crucial role in galaxy evolution. However, the correlation between mergers and the local environment of galaxies is not fully understood. We aim to address th…
Pitfalls of AI classification of rare objects: Galaxy Mergers
W. J. Pearson, L. E. Suelves, S. C. -C. Ho +3
Galaxy mergers are hugely important in our current dark matter cosmology. These powerful events cause the disruption of the merging galaxies, pushing the gas, stars and dust of the…
Merger identification through photometric bands, colours, and their errors
L. E. Suelves, W. J. Pearson, A. Pollo
Aims. We present the application of a fully connected neural network (NN) for galaxy merger identification using exclusively photometric information. Our purpose is not only to tes…
North Ecliptic Pole merging galaxy catalogue
W. J. Pearson, L. E. Suelves, S. C. -C. Ho +17
We aim to generate a catalogue of merging galaxies within the 5.4 sq. deg. North Ecliptic Pole over the redshift range . To do this, imaging data from the Hyper Supr…
