Some weeks ago, I successfully defended my Physics final degree project, titled "Black holes uniqueness theorems and their violation due to scalar fields," so I can officially call myself a physicist! Despite the vast amounts of time required, I enjoyed working on this project. We modified General Relativity by introducing a probe scalar field to observe what happens to Black Holes. The answer is, surprisingly, nothing—the scalar field is generally trivial. This outcome aligns with one of GR's most significant theorems: the no-hair theorem, which states that black holes depend only on their mass (M), charge (Q), and angular momentum (L), and not on some scalar field! However, our work reproduces a strong result: the field may be non-trivial if its squared mass is negative. This scenario only makes sense in every theoretical physicist's favorite spacetime: Anti-de Sitter spacetime. Here, a solution may exist that depends on other parameters besides M, Q, and L, thus violating the no-hair theorem! This result is relevant because, in the context of holography, these 'hairy black holes' correspond to thermodynamic systems exhibiting superconductor phase transitions! Although this sounds fascinating, we did not explore these issues (nor could I without more time and study!). With this, I conclude my graduate studies. I want to thank my family and friends for their support, as well as my advisor for his guidance. I also want to announce that have been accepted into the Astrophysics, Particle Physics, and Cosmology master's program at the University of Barcelona's Physics Faculty next year. This might be the step before a potential PhD, which I eagerly look forward to, and I will undertake it with even more motivation and determination. There's still much to learn!

Yes, the photo didn't turn out great... the lighting... But! The decisions made following it were very significant! I insist that children are intelligent, and with the right atmosphere, a quality environment, supportive parents who speak to their children at eye level and mediate what's happening correctly, they can grow, develop, and achieve great things. Recently, I had the opportunity to talk about Dr. Yotam Sherf... First, let me introduce him and then explain why such a person is important for the system and the good news. Dr. Yotam Sherf, a researcher in black holes and gravitational waves, joins the faculty of Bareket Academy! Yotam, who holds a PhD in Theoretical Physics from Ben-Gurion University and is a postdoctoral researcher in the Astrophysics Department at the Max Planck Institute in Germany, will join Bareket Academy's faculty. He will teach courses in astrophysics, the Big Bang, space technologies, and the universe. These fields are considered critical for developing today's children who will become future Israeli researchers and scientists exploring the universe, its laws, and functions. In our meeting, I explained to Yotam that "The State of Israel must train the next generation of space technology experts, among other things, to develop the tools essential for securing its future as a technological superpower, capable of protecting its territories and national interests through these technologies." Dr. Yotam Sherf is a leading researcher in black holes and gravitational waves. Throughout his career, Yotam has served as a teaching assistant and lecturer at Ben-Gurion University and delivered popular science lectures to high school students to encourage science studies. Currently, he is researching questions like "What's inside a black hole?" and "What can mysterious black holes teach us about the quantum world?" Dr. Sherf joins the faculty because he is vital and crucial for the present and future generation of Israel, who will lead us to become a leading technological superpower. The honor is all ours!

A couple of weeks ago my student Ramada Sukarmadji successfully defended her PhD thesis titled “Deciphering the nanojet phenomenon in the solar atmosphere through observations and numerical simulations”. Congratulations Ramada!! Her thesis investigates the fascinating new “nanojet” phenomenon linked to the heating of the solar corona. As the title states, Ramada investigated this phenomenon by conducting both observations (with no less than 5 instruments) and 3D MHD numerical simulations by securing twice HPC time on DiRAC supercomputers. For her investigation she delved in magnetic reconnection and magnetohydrodynamic wave theory. During her PhD, Ramada became planner for the IRIS solar mission, which basically means that she became the IRIS “pilot” for 2 weeks, deciding what to observe and how to do it with IRIS, and produced the “nanojet program”, which was designed to capture nanojets and has become very successful (has been executed hundreds of times). Ramada obtained a Turing Mobility Award, with which she visited Lockheed Martin Space and Astrophysics Laboratory to work on machine learning-based automatic detection of nanojets. Overall, Ramada produced 2 excellent publications, with many more on the way, showing how important nanojets can be to explain the heating of the solar corona, what their properties are and how do they form. The structure of her thesis is particularly interesting. She has structured it as a review of the nanojet phenomenon, placing together all the data collected in her work from the multiple approaches (observations, simulations, machine learning methods), making sure that all measurements are consistently made with the same methods, allowing a far clearer and general perspective of the phenomenon. Such a thesis can only be made through the wide spanning research that Ramada has done. Her excellent work is also reflected in the multiple invited talks that she has delivered in renowned international conferences in the field. Very well done Ramada!!

At the Department of Physics and Astronomy, SNS, NUST, weekly research seminars serve as a vital platform for fostering academic exchange, sparking intellectual curiosity, and nurturing innovation. These seminars bring together faculty, students, and researchers to engage with cutting-edge ideas in the world of physics and astronomy, creating an environment where knowledge thrives. In our most recent Physics Seminar Series, we had the privilege of hosting Dr. Noraiz Tahir, Assistant Professor at SNS, NUST, whose research interests lie in theoretical astrophysics and astronomy. Dr. Tahir delivered an inspiring talk on "The Mysterious Baryons in the Universe – A Hunt for the Baryonic Dark Matter." He delved into the long-standing mystery of dark matter, starting from Zwicky’s pioneering observations and Vera Rubin’s discovery of flat rotational curves, leading to the elusive concept of galactic halos. Highlighting the "missing baryon problem," he discussed the challenges of identifying the unseen baryonic matter suggested by the ΛCDM cosmological model. Dr. Tahir shared insights into how studying dark halos can help address these questions and outlined future directions in unraveling the mystery of baryonic dark matter. These seminars are not just about sharing research; they are a gateway for collaboration and inspiration, where students and scholars alike gain exposure to the forefront of scientific exploration. We look forward to many more enriching sessions that continue to illuminate the mysteries of the Universe. #PhysicsSeminars #Astrophysics #DarkMatter #ResearchAtSNS #NUSTSNS #ScienceAndInnovation

📃Scientific paper: Direct detection of dark matter: a critical review Abstract: The nature of the dark matter in the Universe is one of the hardest unsolved problems in modern physics. Indeed, on one hand, the overwhelming indirect evidence from astrophysics seems to leave no doubt about its existence; on the other hand, direct search experiments, especially those conducted with low background detectors in underground laboratories all over the world seem to deliver only null results, with a few debated exceptions. Furthermore, the lack of predicted candidates at the LHC energy scale has made this dichotomy even more puzzling. We will recall the most important phases of this novel branch of experimental astro-particle physics, analyzing the interconnections among the main projects involved in this challenging quest, and we will draw conclusions slightly different from how the problem is commonly understood. ;Comment: 28 pages, 15 picture, 2 tables Continued on ES/IODE ➡️ https://etcse.fr/9FD ------- If you find this interesting, feel free to follow, comment and share.
