🌕 Supercomputer Simulations Reveal New Insights into the Moon’s Formation What if the Moon formed instantly, right after a colossal impact? 💥 Scientists from Durham University’s Institute for Computational Cosmology used groundbreaking supercomputer simulations to offer a new theory on the Moon's origin. According to their research, a giant impact may have immediately placed a Moon-like body into orbit around Earth, challenging traditional gradual formation models. These simulations are the most detailed yet, offering fresh perspectives on how one of the most recognizable features of our sky might have come to be. 🔗 Read more supercomputer simulations and the moon's origin: https://lnkd.in/di2mGdys 💳 Credit: Durham University #MoonFormation #Supercomputing #Astrophysics #SpaceScience #ComputationalCosmology #CosmicImpact #TechInnovation #DurhamUniversity #SpaceExploration #ScientificDiscovery

Something I can't wrap my head around while developing this Black Hole Gravitational Simulation for my capstone project is the implementation behind using the 5 Lagrange points. Erin Kara does a really good job explaining how measuring time lags in black holes' X-ray glows can contribute to what is near and surrounding these singularities. I wonder if measuring those echoes could provide a more reliable and sustaining way to use the 2-body system problem in calculating accurate positions when orbiting a rotating black hole. This could help explain that a single satellite/spacecraft near this gargantuan black hole could give off the same gravitational effects when implementing the 5 Lagrange points. Could the usage of the reverberation mapping technique that Erin mentions be more beneficial to using the Newman Janis algorithm for my C++ outputs? Just some interesting thoughts I had as I overthink on my Capstone Project :) Orbital Dynamics Technology Solutions Computational Engineering and Physical Modeling #astrophysics #cplusplus To See Black Holes in Detail, She Uses “Echoes” Like a Bat.

FRBs and their polarization. Researchers led by Ayush Pandhi from the University of Toronto, analyzing data from the Canadian Hydrogen Intensity Mapping Experiment (CHIME), have found a significant difference between repeating and non-repeating Fast Radio Bursts (FRBs). Repeating ones lacks polarization, possibly due to the scattering of emissions as the radiation gets through materials around the source. Non-repeating FRBs are polarized, and might have originated in a less extreme environment, being the polarization something intrinsic to the process that produce them. The findings have been published in The Astrophysical Journal (11 June, 2024). https://lnkd.in/dDDJcMbB #physics #physicsnews #astrophysics #astronomy #radioastronomy #chime #polarization #frb #frbs

🌌 CENTRA Research News! 🌌 Richard Brito, #FCT researcher at Instituto Superior Técnico, just published "Tidal heating as a discriminator for horizons in equatorial eccentric extreme mass ratio inspirals" in Physical Review D - American Physical Society The study investigates tidal heating in binary black hole systems, focusing on energy and angular momentum absorption by the black hole’s horizon. It highlights the significance of this phenomenon during the late stages of an extreme mass ratio inspiral (EMRI) into a rapidly spinning massive black hole, crucial for future low-frequency gravitational-wave observations by missions like LISA. Extending previous analyses to include equatorial EMRIs with generic eccentricities, the research emphasizes that accurate tidal heating modelling is vital to avoid significant dephasing and errors in EMRI parameter estimation. Additionally, it explores how small deviations in radiation absorption can be distinguished from the black hole case. 🔗 Explore the paper here: https://lnkd.in/dhWcpffu #Physics #BlackHoles #GravitationalWaves #ScientificResearch #CENTRA #Astrophysics #TidalHeating #SpaceScience #ResearchInnovation

From a vantage point high in the Chilean Andes, cosmologists with the Simons Observatory have begun searching for evidence of what happened in the minuscule fraction of a second that followed the Big Bang. https://lnkd.in/ek_y8J-y #science #astrophysics

"An international team of scientists, led by the Department of Physics at the University of Oxford , has developed a novel way to experimentally produce #plasma ‘fireballs’ on Earth, opening up a new frontier in laboratory astrophysics". #Blackholes and #neutronstars are the most compact objects in the universe. Around these extreme astrophysical environments exist plasmas, the fourth fundamental state of matter alongside solids, liquids, and gases. The intense gravity of these dense objects pulls in nearby matter and also causes them to shoot out powerful jets of plasma, mainly made of pairs of electrons and their antimatter counterpart, positrons. While these jets are often seen in space, creating them in a laboratory has proved highly challenging so far". #Physics #Astrophysics #PhysicalModels

"Time is associated with matter and energy. Electromagnetic energy is obviously in dynamic movement, but matter is not always quite so obviously a dynamic matrix of ‘energy with its tail in its mouth’."
