Very-high-energy astrophysics studies the most energetic photons in the sky, allowing the exploration of violent and extreme non-thermal phenomena in the Universe. Significant advances in knowledge have been made in this field using ground-based imaging atmospheric Cherenkov telescopes (IACTs) as detectors, to study these physical processes in the Universe. This book reviews the progress in the field since the advent of the second generation IACTs around 2004. Going through the scientific highlights obtained by the three current instruments of this kind, H.E.S.S., MAGIC and VERITAS, operating now for more than 15 years, this book presents a state-of-the-art knowledge in four areas of modern astrophysics and cosmology, namely the origin of the cosmic rays, the physics of compact objects and their resulting relativistic outflows, gamma-ray cosmology, and the search for dark matter. Along with a detailed review of the outstanding scientific outcomes, a summary of the key technological developments that yielded the recognized success of the technique is also provided. This book edited by 𝐑𝐞𝐬𝐡𝐦𝐢 𝐌𝐮𝐤𝐡𝐞𝐫𝐣𝐞𝐞 (Columbia University, USA) and 𝐑𝐨𝐛𝐞𝐫𝐭𝐚 𝐙𝐚𝐧𝐢𝐧 (Max-Planck-Institut für Kernphysik, Germany) is written for early-career academics in the fields of astrophysics, high energy physics and cosmology. At the same time, it can serve as a source of reference for the expert in the field. Quote WH24 for 25% OFF!

From testing quantum gravity to tracking satellites with rapid trajectories, Alan Chan, is unravelling the mysteries of the cosmos one small step at a time. Alan, studying astrophysics and experimental physics at The Australian National University's Mt. Stromlo Observatory, recently completed the first Australian Milo Mission Academy for Lunar Exploration, in partnership with AROSE. The academy offered Australian students with a passion for space to participate in internationally recognised space workforce training. “As an astrophysics and experimental physics student, it was fascinating to see how people with experiences in computer science, engineering, and even law approach problems and contribute their unique perspectives. The exchange of ideas broadened my perspective and deepened my understanding of the complexities of space exploration. I would definitely recommend this program to future participants.” Read more: https://lnkd.in/gyW4Xq3V #Trailblazers The Milo Space Science Institute Arizona State University Australia's Economic Accelerator (AEA)

I am thrilled to share that I received the BRONZE Honour in the International Astronomy and Astrophysics Competition 2024 in the 'YOUTH' category. After successfully navigating both the Preliminary and Pre-final rounds, this achievement feels incredibly rewarding as the rounds were not easy to conquer. ✅ The qualification round is the first stage which consisted of five astronomy problems that have been published. The problems test the astronomy knowledge, others require calculations. This round not only sharpen my mind but also raised my knowledge about astronomy and astrophysics! ✅ In the PRE-Final round, the problems were more challenging, but even more interesting! It consisted of six different problems that vary in difficulty, points, and topic: 2x basic problems (four points), 2x advanced problems (six points), 2x research problems (eight points). Throughout this journey, I have gained invaluable knowledge and experiences. It has been an amazing opportunity to challenge myself and grow in a field I am deeply passionate about. Thank you to everyone who supported and encouraged me along the way. #Aerospace #Astrophysics #Astronomy #IAAC24 #Curiosity #ContinuousLearning #ProblemSolving

When neutron stars collide, hot neutrinos — tiny, essentially massless particles that rarely interact with other matter — are created. New simulations done by #PennState physicists show that these particles can be briefly trapped and out of equilibrium with the cold cores of the merging stars for two to three milliseconds. This research lends new insight into the physics of these powerful events. “These extreme events stretch the bounds of our understanding of physics and studying them allows us to learn new things,” said David Radice, assistant professor of physics and of astronomy and astrophysics.

I am thrilled to share that I have been elected as a Fellow of the Royal Astronomical Society —an incredible milestone in my journey as a PhD researcher. Today, I’m attending *Exploring the Low-Surface-Brightness Universe with Next-Generation Instruments* at the Geological Society, Burlington House, London. As someone deeply invested in understanding how faint and elusive structures like low-mass galaxies, tidal features, and diffuse light contribute to the broader cosmic story, this event resonates deeply with my research interests. With instruments like the Rubin Observatory, Euclid, and JWST redefining the boundaries of what we can observe, the low-surface-brightness regime holds the key to understanding galaxy formation and hierarchical mass assembly. As a researcher investigating the impact of satellite constellations on astronomical observations, I’m particularly excited about the discussions around data challenges and innovative approaches like machine learning and simulations to maximize the potential of these datasets. It’s inspiring to connect with a community of brilliant minds committed to unraveling the faintest mysteries of the universe. Here’s to pushing the frontiers of astrophysics together! #RoyalAstronomicalSociety #Astrophysics #LowSurfaceBrightnessGalaxies #NextGenerationInstruments #PhDResearch

I’m excited to share that I recently completed the Gravitational-Wave Astronomy Summer School hosted by International Centre for Theoretical Sciences in July 2024! Even though it was an online program, it was truly a one-of-a-kind experience. Over the two weeks, I had the opportunity to dive into topics like: - The astrophysics of neutron stars and binaries, uncovering how they contribute to gravitational-wave signals. - The fascinating theory of ultralight boson clouds around black holes, opening new possibilities in black hole physics. - The mechanics behind rapidly spinning neutron stars and their emission processes. - The latest methods in the search for continuous gravitational waves, which showed me both the complexities and possibilities in detection. - Plus, I gained hands-on experience with data analysis techniques, furthering my skills in interpreting astronomical datasets. A huge thank you to International Centre for Theoretical Sciences for organizing such a comprehensive and interactive program. Even though it was virtual, the learning was rich, engaging, and inspiring. It was an unforgettable experience that has deepened my passion for astrophysics and gravitational-wave research! 🚀 #GravitationalWaves #Astrophysics #SpaceScience #DataAnalysis #NeutronStars #BlackHoles #OnlineLearning #ICTS #STEM #Research #ContinuousLearning
