76. Latest results from the LVK O4a observing run

Gergely Dálya (L2IT, Toulouse)

20/10/2025 14:00

In this talk, that I will give on behalf of the LVK Collaboration, I will present the latest results from the O4a observing run, placing a special emphasis on the new events in GWTC-4, the multi-messenger and cosmological results obtained.

114. High-energy neutrino alerts and their follow-up observations

Marcos Santander (University of Alabama)

77. Radio variability with ASKAP and LOFAR

Iris de Ruiter (University of Sydney)

20/10/2025 14:40

In this talk, I will discuss the current state of transient studies in the radio domain. With SKA precursor and pathfinder instruments, we are collecting unprecedentedly rich and dense datasets, opening new frontiers in transient astronomy. However, this rapid data influx presents key challenges, particularly in storage and accessibility of light curve data. I will highlight these challenges...

79. ATLAS

Heloise Stevance (University of Oxford)

81. The Gravitational-wave Optical Transient Observer (GOTO) project

Joseph Lyman (University of Warwick)

20/10/2025 15:55

I will present the GOTO project: an array of wife-field survey telescopes principally aimed at following gravitational wave (GW) alerts and performing rapid searches of the localisation areas. The array is situated over two sites, covering Northern and Southern skies, performing an all-sky optical survey, alongside multi-messenger follow up. In addition to GW alerts, GOTO regular reacts to...

74. IceCube: public GFU alerts (tbc)

75. KM3NeT: public alerts (tbc)

78. Small Aperture Telescopes and Multimessenger Follow-Up Networks

Kyle Hart

With the increasing number of high-energy detectors and transient surveys our community is increasingly bottle necked with our ability to perform adequate optical and spectral follow-up observations at scale. In this talk I will discuss the robotization of Manua Kea's oldest telescope, UH88. The system we are building may serve as the foundation for further automation in small/medium aperture...
