Following on from my previous post, I am delighted to share my final undergraduate project: Dark Matter Direct Detection. This project combined elements from many of my undergraduate modules, including Atomic Physics, Particle Physics, Cosmology, Astrophysics, and Scientific Computing. I am thrilled to have received a first-class mark for this project, as well as for the module overall, which also included several report writing and presentation tasks. The abstract for this project is included at the bottom of this post, and the PDF of my final submission is attached for those interested in learning more. If anyone has any questions regarding any elements of this project, please don't hesitate to get in touch. I will do my best to answer them for you. Abstract: The search for dark matter remains one of the most compelling topics in physics. Despite decades of searching, conclusive evidence of a direct detection remains elusive. We explore the factors that contribute to a model for the expected number of events for different hypothetical Weakly Interacting Massive Particle (WIMP) masses, considering factors from nuclear physics, particle physics and astrophysics. This model is then examined for a number of different detector nuclei, establishing and exploring the relationship of heavier nuclei being superior for heavier WIMP masses, and vice-versa. The assumptions made in this model are examined and a brief overview of other experiments is given. Finally, the investigation delves into the importance of the WIMP-Proton cross section and its continuously diminishing threshold, which casts doubt on the WIMP's status as the primary dark matter candidate.

"Beyond Astrophysics: Exploring Exciting Paths in Physics" I remember the first day of my undergraduate studies. After introducing ourselves to the professor 👨🏫 , he asked, "So, which field are you all interested in for research?" Almost everyone said astrophysics 🌃, and those who didn't weren't sure what they wanted. The professor wasn't surprised—this happens every year. I was the same. Undoubtedly, astrophysics and astronomy hold a special place in our hearts and have good opportunities too. But today, research 📑 in astrophysics isn't quite what we imagined in high school—going to high hills, taking pictures, reading about the universe's formation, and coming up with our own theories. It's much more computational now, involving abstract calculations, data analysis, and complex theories. If you're a research enthusiast in physics, try exploring other fascinating fields like technology development, product development, material synthesis, and more. Consider exploring fascinating fields such as photonics, ultrafast technology, flexible electronics, semiconductors, and superconductors and many more. These areas are at the forefront of innovation and offer exciting opportunities for discovery and development. So, while your fascination with the universe is valid and important, don't hesitate to explore the diverse and dynamic areas within physics. Each field has its own unique challenges and rewards, contributing to our understanding and shaping the future. #astrophysics #physicist #research #product #technology #physics #astronomy #

Nobel Prize in Physics 2022: Groundbreaking Discoveries in Quantum Mechanics and Astrophysics Celebrate the remarkable achievements of this year's Nobel Prize winners in Physics! The prestigious award honors three exceptional scientists for their transformative contributions to our understanding of the quantum world and the mysteries of the cosmos. Alain Aspect, John F. Clauser, and Anton Zeilinger were recognized for their groundbreaking experiments in quantum entanglement, laying the foundation for emerging technologies like quantum computing and quantum encryption. Their work has unlocked new realms of possibility and continues to inspire scientific exploration. Additionally, the Nobel Prize highlighted the pioneering research of James Peebles, who played a pivotal role in shaping our current model of the universe's evolution. His theoretical predictions about the cosmic microwave background radiation and the existence of dark matter have profoundly impacted our comprehension of the universe's origins and structure. Share your thoughts and insights on these remarkable discoveries, and join the conversation as we applaud the tireless pursuit of knowledge that drives scientific progress forward. #NobelPrize #Physics #QuantumMechanics #Astrophysics #ScientificDiscoveries Read the Full Article: https://lnkd.in/gaQpy3Qe

Astrophysicists believe that “#darkenergy” or “#cosmologicalconstant”, responsible for the accelerating expansion of the #universe, is maybe weakening over time. However, the results fall short of the five sigma statistical significance required of physics discoveries - the results maybe statistical fluctuations or real discovery. https://lnkd.in/g6g6AfG2

Honored to receive the MRE Young Scientist Nomination Award! 🚀 I'm glad to share that I've been awarded the Young Scientist Nomination Award by Matter and Radiation at Extremes (MRE)! 💡 The work investigates the mechanisms of matter heating by laser-accelerated relativistic electrons through X-ray imaging. This research is important for understanding fundamental physics under extreme conditions, with applications ranging from inertial confinement fusion to astrophysics. I couldn't have achieved this without my amazing colleagues' unwavering support and collaboration in the Plasma Physics Department at GSI Helmholtz Centre for Heavy Ion Research. Especially, many thanks to Paul Neumayer (GSI) and Dimitri Batani (Bordeaux Uni) ✍️ Soon there will be a publication about it.

Physics is the properties of energies and how they react to each other. Force is how energy pulses or organized energies react to similar or different energies. This is the basis of the ilefos model. Gravity can then be explained with a clear cause-effect explanation which works in quantum mechanics and astrophysics. This model and its explanation of physics also explain dark energy, dark matter and other universal phenomena including the accelerating expansion of the universe. “If you have a problem you can’t solve, you might have to start over and attack it with a different approach. What seem insolvable often have a solution if you change the rules and your angle of attack.” This also applies to science. Why can’t we find answers to nature’s most basic questions? Are we working within an unsolvable framework? A correct physics must work in all areas, it must work with quantum mechanics and astrophysics. The ilefos model is a new approach to explain universal basics like gravity, dark energy, dark matter and other universal phenomena with a clear cause-effect explanation, which works in quantum mechanics and astrophysics. Here is a book with an introduction to the ilefos model: https://lnkd.in/gPHQhzGn
