GRB220831A: a hostless, intermediate Gamma-ray burst with an unusual optical afterglow
James Freeburn, Brendan O'Connor, Jeff Cooke +20
GRB220831A is a gamma-ray burst (GRB) with a duration and spectral peak energy that places it at the interface between the distribution of long-soft and short-hard GRBs. In thi…
An Optically Led Search for Kilonovae to z0.3 with the Kilonova and Transients Program (KNTraP)
Natasha Van Bemmel, Jielai Zhang, Jeff Cooke +15
Compact binary mergers detectable in gravitational waves can be accompanied by a kilonova, an electromagnetic transient powered by radioactive decay of newly synthesised r-process…
A very luminous jet from the disruption of a star by a massive black hole
Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78
Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…
The Deeper, Wider, Faster programme's first DECam optical data release
James Freeburn, Jeff Cooke, Anais Möller +17
The transient and variable optical sky is relatively poorly characterised on fast (1hr) timescales. With the Dark Energy Camera (DECam), the Deeper, Wider, Faster programme…
Unsupervised machine learning for transient discovery in Deeper, Wider, Faster light curves
Sara Webb, Michelle Lochner, Daniel Muthukrishna +7
Identification of anomalous light curves within time-domain surveys is often challenging. In addition, with the growing number of wide-field surveys and the volume of data produced…
A Fast-cadenced Search for Gamma-Ray Burst Orphan Afterglows with the Deeper, Wider, Faster Programme
James Freeburn, Jeff Cooke, Anais Möller +11
The relativistic outflows that produce Long GRBs (LGRBs) can be described by a structured jet model where prompt -ray emission is restricted to a narrow region in the jet's cor…
The Deeper, Wider, Faster Program: Exploring stellar flare activity with deep, fast cadenced DECam imaging via machine learning
Sara Webb, Chris Flynn, Jeff Cooke +9
We present our 500 pc distance-limited study of stellar fares using the Dark Energy Camera as part of the Deeper, Wider, Faster Program. The data was collected via continuous 20-se…
Realistic Equations of State Informing Neutron Star Post-Merger Gravitational-Wave Frequencies
Spencer J. Magnall, Nilaksha Barman, Debarati Chatterjee +2
Binary neutron star mergers are thought to produce hot, rapidly rotating neutron stars with masses that can far exceed their Tolman-Oppenheimer-Volkoff mass. The gravitational-wave…
Finding Fast Transients in Real Time Using Novel Light Curve Analysis Algorithm
Robert Strausbaugh, Antonino Cucchiara, Michael Dow +4
The current data acquisition rate of astronomical transient surveys and the promise for significantly higher rates during in the next decade necessitate the development of novel ap…
