Identifying new white dwarfs (WDs) heavy elements is crucial, as they serve as valuable tools for deducing the chemical characteristics of potential planetary systems accreting material onto their surfaces. To detect metallic WDs, we propose a methodology based on an unsupervised learning technique known as Self-Organizing Maps (SOM). This approach

The observation and interpretation of the universe in general have played a major role in cultures from different times and epochs. Studying this role is the main goal of a discipline called "cultural astronomy" or "astronomy in culture". With a tradition of more than three decades, it is an interdiscipline halfway between astronomy and social

Microwave and radio observations exhibit some interesting features in the Galactic plane. One of those is the Fan region which is an extended region located in the Perseus arm at a distance of 500 pc. Fan region has highly polarized emission from several MHz up to 353 GHz, which is ascribed to synchrotron but nowadays is largely unexplained. Here
