Narrow-line Seyfert 1 galaxies (NLS1s) are a class of active galactic nuclei (AGN) and were long believed to be radio-silent and incapable of producing relativistic jets; however, recent studies have demonstrated otherwise. The Fermi Large Area Telescope (LAT) made a groundbreaking discovery by detecting gamma-ray emission from the NLS1 source PMN J0948+0022, providing clear evidence that some of these sources can host relativistic jets in this class of AGN. This challenged the idea we had of NLS1s and their diversity.

Over the years, many new sources have been discovered, and my researchers have focused on analyzing these findings by systematically searching for additional gamma-ray-emitting NLS1s using data from the Fermi-LAT. For this, a series of analyses are run to evaluate the test statistic (TS) value, which provides a measure of the significance of potential detection.

This poster will present an overview of narrow-line Seyfert 1 galaxies (NLS1s), the methodology applied in this study, relevant previous findings, the analysis procedure, and the automation of code used to conduct the analysis. Current results will be discussed, highlighting the test statistic (TS) values obtained thus far. As this project represents ongoing research, additional TS values will be identified over time, culminating in a more comprehensive analysis.
