“…All the predictions obtained with our best-performing method-embedding ranking pipeline-are publicly available via search API [6] and GitHub repository [30]. Using this API, our functionality can be integrated with multi-messenger brokers and platforms, e.g., with Astro-COLIBRI [31,32], to provide complementary information for human-written messages. In the coming months, we are also planning to release the first version of the web application for searching and crossreferencing ATels and GCN circulars using the data extracted with our LLMs.…”

With the increasing reliance of astronomy on multi-instrument and multi-messenger observations for detecting transient phenomena, communication among astronomers has become more critical. Apart from automatic prompt follow-up observations, short reports, e.g., GCN circulars and ATels, provide essential human-written interpretations and discussions of observations. These reports lack a defined format, unlike machine-readable messages, making it challenging to associate phenomena with specific objects or coordinates in the sky. This paper examines the use of large language models (LLMs)—machine learning models with billions of trainable parameters or more that are trained on text—such as InstructGPT-3 and open-source Flan-T5-XXL for extracting information from astronomical reports. The study investigates the zero-shot and few-shot learning capabilities of LLMs and demonstrates various techniques to improve the accuracy of predictions. The study shows the importance of careful prompt engineering while working with LLMs, as demonstrated through edge case examples. The study’s findings have significant implications for the development of data-driven applications for astrophysical text analysis.

Observations of transient phenomena like Gamma-Ray Bursts (GRBs), Fast Radio Bursts (FRBs), stellar flares and explosions (novae and supernovae), combined with the detection of novel cosmic messengers like high-energy neutrinos and gravitational waves has revolutionized astrophysics over the last years. The discovery potential of both ulti-messenger and multi-wavelength followup observations as well as serendipitous observations could be maximized with a novel tool which allows for quickly acquiring an overview over relevant information associated with each new detection. Here we present Astro-COLIBRI, a novel and comprehensive platform for this challenge. Astro-COLIBRI's architecture comprises a public RESTful API, real-time databases, a cloudbased alert system and a website as well as apps for iOS and Android as clients for users. Astro-COLIBRI evaluates incoming messages of astronomical observations from all available alert streams in real time, filters them by user specified criteria and puts them into their MWL and MM context. The clients provide a graphical representation with an easy to grasp summary of the relevant data to allow for the fast identification of interesting phenomena, provides an assessment of observing conditions at a large selection of observatories around the world, and much more.Here the key features of Astro-COLIBRI are presented. We outline the architecture, summarize the used data resources, and provide examples for applications and use cases. Focussing on the high-energy domain, we'll discuss the use of the platform in searches for high-energy gamma-ray counterparts to high-energy neutrinos, gamma-ray bursts and gravitational waves.

“…In the interpretation of quasi-periodic oscillations due to jet precession induced by a SMBBH system, [10] built a precession model to explain the recurrent neutrino emission in TXS 0506+056 observed by the Antarctic IceCube Neutrino Observatory [16,17]. They connected for the first time the possible neutrino and gravitational-wave signatures of such sources, demonstrating the need for continued multi-messenger monitoring [29]. This precession model predicted a new neutrino emission period that turned out to be consistent with the 18/09/2022 neutrino observation by IceCube and relied on the jet precession first reported by [8] for this source.…”

In this paper we present the multimessenger picture of the flat-spectrum radio quasar (FSRQ) J1048+7143, a blazar showing gamma-ray quasi-periodic oscillations. We generate the adaptively binned Fermi-LAT light curve of this source above 168 MeV and find three major 𝛾-ray flares, such that each of the flares resolves into two subflares. By analyzing arcsec-scale and milliarcsecscale radio interferometric observations, we find signatures of the precession of a spine-sheath structured jet. We analyze the 5 GHz total flux density curve of J1048+7143 taken with single-dish radio telescopes, and find three complete radio flares that are also suggestive of jet precession. We model the timing of gamma-ray flares as a signature of the spin-orbit precession in a supermassive black hole binary and find that the binary could merge in the next 60-80 yrs.
