Title: Exploring the Depths of Space: Detecting and Studying Extragalactic Gamma-Ray Sources
An exciting new thesis delves into the world of extragalactic soft-spectrum gamma-ray sources, shedding light on their detection and characteristics in the energy range of 50 GeV to 50 TeV. Furthermore, it explores the potential of machine learning techniques to enhance their detection, uncovering valuable insights into these distant cosmic phenomena.
Blazars, a remarkable class of galaxies, are at the center of this investigation. These galaxies house supermassive black holes that consume vast amounts of matter, releasing immense energy that accelerates charged particles to nearly the speed of light. However, the precise details of these extreme processes remain uncertain, making further observational studies crucial in distinguishing between various theories.
One of the most powerful tools in this endeavor is the study of very high-energy (VHE) gamma rays. These gamma rays are intricately linked to the most energy-rich regions within Blazars. By observing gamma rays, we gain direct insights into the central engine responsible for the incredible amounts of radiation detected.
The study conducted in this thesis incorporates the use of the H.E.S.S. observatory, an Imaging Atmospheric Cherenkov Telescope that leverages our atmosphere as an essential component of its detector. Capable of detecting gamma-ray photons with energies ranging from over 50 GeV to tens of TeV, H.E.S.S. allowed for a detailed investigation of seven new sources of gamma rays in the VHE regime. This significant expansion of known sources of TeV photons contributes to unraveling the mysteries of Blazars.
In addition to observational studies, computer simulations were performed to explore the potential of deep learning techniques. The focus was on improving the sensitivity of ALTO, a newly-proposed observatory belonging to the emerging class of gamma-ray instruments known as particle detector arrays. By harnessing the power of deep learning, scientists aim to enhance the capabilities of ALTO, paving the way for more efficient and accurate detections in the realm of gamma-ray astronomy.
This latest research not only contributes to our understanding of the universe but also holds promise for future advancements in observational astronomy. By employing cutting-edge technologies like machine learning, scientists can push the boundaries of what we know about extragalactic soft-spectrum gamma-ray sources. As our knowledge grows, we inch closer to deciphering the intricate processes at play within Blazars and unraveling the mysteries of the cosmos.
The thesis sets a solid foundation for further studies in this captivating field, shedding light on the secrets of the universe and bringing us closer to unlocking its hidden treasures.
