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…

The FIRESTORM project--Feedback-Induced Regions and Emission from Star-forming Tracers of ObseRvable Molecular Gas--has targeted four star-forming regions to quantify the impact of…
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…
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…
