AT 2020afjz (TSS2020a): The First Fast Extragalactic Transient Discovered by TESS
Ryan Ridden-Harper, Hugh Roxburgh, Clarinda Montilla +13
We report the discovery of AT 2020afjz (TSS2020a): the first hour-scale extragalactic transient discovered in optical wavelengths whose complete evolution -- from explosion onset t…
ASAS-SN Rates IV: Constraints on the Kilonova Rate
Dhvanil D. Desai, Benjamin J. Shappee, Christopher S. Kochanek +10
Kilonovae (KNe) are the electromagnetic signatures of neutron star mergers and are likely the dominant site of cosmic -process nucleosynthesis. However, their intrinsic rate rem…
AT 2024wpp: the most luminous fast-evolving optical transient linked to the merger explosion of a black-hole binary
Jialian Liu, Bao Wang, Xiaofeng Wang +48
Fast blue optical transients (FBOTs) represent one of the most exotic astrophysical transients, exhibiting unusually strong emission across X-ray, optical, and radio wavelengths. T…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
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…
SN 2023taz: Implications for the UV Diversity of Superluminous Supernovae
Aysha Aamer, Matt Nicholl, Charlotte Angus +21
Superluminous supernovae (SLSNe) are some of the brightest explosions in the Universe representing the extremes of stellar deaths. At the upper end of their distribution is SN\,202…
SN 2019vxm: A Shocking Coincidence between Fermi and TESS
Zachary G. Lane, Ryan Ridden-Harper, Sofia Rest +37
Shock breakout and, in some cases, jet-driven high-energy emission are increasingly recognized as key signatures of the earliest phases of core-collapse supernovae, especially in T…
A follow-up strategy enabling discovery of electromagnetic counterparts to highly-magnified gravitationally-lensed gravitational waves
Dan Ryczanowski, Jeff Cooke, James Freeburn +6
Making an unambiguous detection of lensed gravitational waves is challenging with current generation detectors due to large uncertainties in sky localisations and other inferred pa…
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…
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…
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 core…
SOAR/Goodman Spectroscopic Assessment of Candidate Counterparts of the LIGO-Virgo Event GW190814
Douglas Tucker, Matthew Wiesner, Sahar Allam +140
On 2019 August 14 at 21:10:39 UTC, the LIGO/Virgo Collaboration (LVC) detected a possible neutron star-black hole merger (NSBH), the first ever identified. An extensive search for…
