Prediction of Major Solar Flares Using Interpretable Class-dependent Reward Framework with Active Region Magnetograms and Domain Knowledge
Zixian Wu, Xuebao Li, Yanfang Zheng +14
In this work, we develop, for the first time, a supervised classification framework with class-dependent rewards (CDR) to predict MM flares within 24 hr. We construct multipl…
Investigating Ionospheric TEC Variations in Solar and Geomagnetic Influences Across Solar Activity Phases
Ziyadat Hassan, Zamri Zainal Abidin, Affan Adly Nazri +1
This study examines the variability of ionospheric total electron content (VTEC) in response to solar and geomagnetic drivers across solar cycles 23 to 25. While the dominant effec…
Operational Solar Flare Forecasting System Using an Explainable Large Language Model
Xuebao Li, Yongshang Lv, Jinfang Wei +14
This study focuses on forecasting major (>=M-class) solar flares that can severely impact the near-Earth environment. We construct two types of datasets using the Space Weather HMI…
Temporal variability in low-frequency radio interference: Insight from high-cadence monitoring at a candidate radio notification zone in Malaysia
Affan Adly Nazri, Zamri Zainal Abidin, Mohamad Ridhauddin Mat Sabri +9
Extensive radio frequency interference (RFI) monitoring is essential in the site selection process before constructing radio astronomy observatories, followed by mitigation strateg…
Investigating the Jet Width Profile of CTA 102 with Very Long Baseline Interferometry at Parsec Scales
ZhanHao Ng, Juan Carlos Algaba, Zamri Zainal Abidin
Active Galactic Nucleus jets have long be thought to exhibit a conical jet shape, but recently, several jets were found to have a transition from parabolic to conical structure. As…
Rethinking Habitability using Biogenic Precursors: Formaldehyde in Millimeter Molecular Clouds of the Inner Galaxy
Nursyazela Badrina Baharin, Affan Adly Nazri, Zulfazli Rosli +5
We present a comprehensive study of formaldehyde (H2CO) absorption and radio recombination line (H110a) emission in 215 molecular clouds from the Bolocam Galactic Plane Survey (BGP…
