High-resolution UV imaging reveals new sources and variability near IC 4329A
Deep ultraviolet imaging of the Seyfert galaxy IC 4329A's field using AstroSat's UVIT revealed thousands of sources, many newly identified, with detailed photometry and astrometry. The study also discovered variable ultraviolet sources and corrected classifications of some objects, highlighting unusual galaxy morphologies.
Why it matters: This deep UV survey uncovers numerous new sources and variable objects, enriching our understanding of the galaxy field around IC 4329A.
The big picture: High-resolution UV imaging combined with optical and X-ray data enables multi-wavelength source characterization and classification refinement.
Stunning stat: 4437 NUV and 456 FUV sources were detected above 5σ, with 28 NUV sources showing significant variability.
The stakes: Misclassified objects and unusual galaxy morphologies require further spectroscopic and multi-wavelength studies to clarify their true nature.
