ORBIT: Cost-Effective Dataset Curation for Large Language Model Domain Adaptation with an Astronomy Case Study

arXiv.org
Recent advances in language modeling demonstrate the need for high-quality domain-specific training data, especially for tasks that require specialized knowledge. General-purpose models, while versatile, often lack the depth needed for expert-level tasks

Young asteroid families as the primary source of meteorites

Nature
Understanding the origin of bright shooting stars and their meteorite samples is among the most ancient of astronomy-related questions, which at larger scales has human consequences1–3.

AstroM3: A Self-supervised Multimodal Model for Astronomy

Astronomical Journal
While machine-learned models are now routinely employed to facilitate astronomical inquiry, model inputs tend to be limited to a primary data source (namely images or time series) and, in the more advanced approaches, some metadata.

The growing impact of unintended Starlink broadband emission on radio astronomy in the SKA-Low frequency range

Astronomy & Astrophysics
We present the largest survey to date characterising intended and unintended emission from Starlink satellites across the SKA-Low frequency range. This survey analyses ∼76 million full sky images captured over ∼29 days of observing with an SKA-Low ...

“Frog-eyes” in astronomy: Monitoring binary radial velocity variations through a pair of narrow-band filters

Science China Physics Mechanics and Astronomy
Spectroscopic observations are a crucial step in driving major discoveries in the era of time-domain surveys. However, the pace of current spectroscopic surveys is increasingly unable to meet the demands of rapidly advancing large-scale time-domain ...

The High Energy X-ray telescope (HE) onboard the Insight-HXMT astronomy satellite

Science China Physics Mechanics and Astronomy, 2019
The Insight-Hard X-ray Modulation Telescope (Insight-HXMT) is a broadband X-ray and γ-ray (1-3000 keV) astronomy satellite. One of its three main telescopes is the High Energy X-ray telescope (HE).

Euclid preparation. LXXI. Simulations and nonlinearities beyond LambdaCDM. 3. Constraints on f(R) models from the photometric primary probes

Astronomy & Astrophysics
We study the constraint on f(R) gravity that can be obtained by photometric primary probes of the Euclid mission. Our focus is the dependence of the constraint on the theoretical modelling of the nonlinear matter power spectrum.
