V407 Vul: a triple star system with an AM CVn detectable by gravitational wave observatories
James Munday, Antonio C. Rodriguez, Nicole Reindl +23
The AM CVn class includes mass transferring, ultra-compact double white dwarf binaries with orbital periods on the timescale of minutes. A long-standing puzzle is that none of the…
Broadband X-ray observations of the periodic optical source ZTF J185139.81+171430.3 and its identification as a massive intermediate polar
Ren Deng, Kaya Mori, Eric Miao +5
We present X-ray observations of the periodic optical source ZTF J185139.81+171430.3 (hereafter ZTF J1851) by the XMM, NICER and NuSTAR telescopes. The source was initially specula…
A Luminous Red Optical Flare and Hard X-ray Emission in the Tidal Disruption Event AT2024kmq
Anna Y. Q. Ho, Yuhan Yao, Tatsuya Matsumoto +30
We present the optical discovery and multiwavelength follow-up observations of AT2024kmq, a likely tidal disruption event (TDE) associated with a supermassive ($M_{\rm BH}\sim 10^{…
A gravitational wave detectable candidate Type Ia supernova progenitor
Emma T. Chickles, Kevin B. Burdge, Joheen Chakraborty +37
Type Ia supernovae, critical for studying cosmic expansion, arise from thermonuclear explosions of white dwarfs, but their precise progenitor pathways remain unclear. Growing evide…
GERry: A Code to Optimise the Hunt for the Electromagnetic Counter-parts to Gravitational Wave Events
David O'Neill, Joseph Lyman, Kendall Ackley +19
The search for the electromagnetic counterparts to gravitational wave (GW) events has been rapidly gathering pace in recent years thanks to the increasing number and capabilities o…
The Gravitational-wave Optical Transient Observer (GOTO)
Martin J. Dyer, Kendall Ackley, Felipe Jiménez-Ibarra +19
The Gravitational-wave Optical Transient Observer (GOTO) is a project dedicated to identifying optical counter-parts to gravitational-wave detections using a network of dedicated,…
