Studying the stars unveils more than celestial mysteries. Today, Nobel-winning astrophysicist Didier Queloz shares insights on using the universe as a laboratory for significant physics discoveries. "From nuclear energy to understanding the Sun, the cosmos fuels innovation," he emphasizes. Queloz, based at the University of Cambridge's Cavendish Laboratory, has expanded his research horizons with a new center at ETH Zurich - the Centre for Origin and Prevalence of Life. Here, an interdisciplinary team focuses on unraveling the profound question: why does life exist in our universe? #Astrophysics #Research #LifeOrigins https://lnkd.in/dGBwCsp5

📃Scientific paper: Astrophysics and Nuclear Physics Informed Interactions in Dense Matter: Inclusion of PSR J0437-4715 Abstract: We investigate how vector-isoscalar and vector-isovector interactions can be determined within the density regime of neutron stars \(NSs\), while fulfilling nuclear and astrophysics constrains. We make use of the Chiral Mean Field \(CMF\) model, a SU\(3\) nonlinear realization of the sigma model within the mean-field approximation, for the first time within a Bayesian analysis framework. We show that neutron-matter $\chi$EFT constraints at low density are only satisfied if the vector-isovector mixed interaction term is included, e.g., a $\omega^2\rho^2$ term. We also show the behavior of the model with respect to the conformal limit. We demonstrate that the CMF model is able to predict a value for the parameter $d\_c$ related to the trace anomaly and its derivative takes values below 0.2 above four times saturation density within a hadronic version of the model that does not include hyperons or a phase transition to deconfined matter. We compare these effects with results from other \(non-chiral\) Relativistic Mean Field models to assess how different approaches to incorporating the same physical constraints affect predictions of NS properties and dense matter equations of state. We also include data from the gravitation wave event GW230529 detected by the LIGO-Virgo-Kagra collaboration and the most recent radius measurement of PSR J0437-4715 from the NASA NICER mission. Our analysis reveals that this new NICER measurement leads to an average reduction of approximately $\sim ...

The most recent Event Horizon Telescope image of polarized light around the Milky Way's nuclear black hole, Sagittarius A*, is a remarkable and stunning image that is revealing some of the inner most dynamics of our galactic nucleus; but as well revealing that the physics of black holes are not yet well understood, and challenging the standard models of astrophysics. Astrophysicists are seeing that their previous models, which did not have strong magnetic fields around black holes, are incorrect, and they are reportedly left perplexed by the high level of coherency of the plasma flow dynamics around Sagittarius A*. However, there is a model from which the high coherency and flow dynamics that are being observed are predicted. From the International Space Federation research team's recent study The Origin of Mass and the Nature of Gravity, available to download on the CERN pre-print server Zenodo- https://lnkd.in/ePrQpm5K - the physics that would explain the remarkable and stunning image are elucidated. Unlike standard models describing black holes as an accumulation of mass in a region of space, here the authors define the discrete fluid structure of spacetime as Planck Plasma flow vortices generating black holes at the origin of mass and forces. From their paper (pg. 22, under the section The Quantum Spacetime Structure): "Contrary to the classical approach, where one would expect the black hole formation to be the result of an accretion of infalling material to a critical limit, our result demonstrates that black hole formation is the result of a natural spacetime behavior emerging from a state of coherency of the collective quantum vacuum fluctuation oscillators in a region of space at different scales. The mechanism that defines these states of coherency are related to the angular momentum of an oscillator, as described by Max Planck originally. The coupling of the oscillators produces collective behaviors or a quantum vortex in a turbulent flow of the spacetime manifold [Planck Plasma flow] in a region of space generating what we observe as a black hole." Image Credit: EHT Collaboration. The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the center of our Galaxy: how it looks in polarized light. #quantumphysics #astrophysics

One of the distinguishing features between stars and planets is their relative mass. Stars have much more mass than planets. The cosmos is full of celestial bodies with mass in between - not massive enough to be a star but way more massive than a typical planet (say 50 times than Jupiter). These bodies are known as Brown Dwarfs because they don't shine through nuclear fusion like our sun but radiate mostly in the infrared through gravitational compression On a recent trip to Tenerife, I met with Professor Eduardo L Martín, from the Instituto de Astrofísica de Canarias (IAC) who happens to be a Brown Dwarf expert. In this interview, he tells me how he will be using data from the European Space Agency's - ESA's Euclid mission, to shed more light on these often overlooked bodies in our universe. https://lnkd.in/eEDp7Y7G

📃Scientific paper: The TRILL project: increasing the technological readiness of Laue lenses Abstract: Hard X-/soft Gamma-ray astronomy (> 100 keV) is a crucial field for the study of important astrophysical phenomena such as the 511 keV positron annihilation line in the Galactic center region and its origin, gamma-ray bursts, soft gamma-ray repeaters, nuclear lines from SN explosions and more. However, several key questions in this field require sensitivity and angular resolution that are hardly achievable with present technology. A new generation of instruments suitable to focus hard X-/soft Gamma-rays is necessary to overcome the technological limitations of current direct-viewing telescopes. One solution is using Laue lenses based on Bragg's diffraction in a transmission configuration. To date, this technology is in an advanced stage of development and further efforts are being made in order to significantly increase its technology readiness level (TRL). To this end, massive production of suitable crystals is required, as well as an improvement of the capability of their alignment. Such a technological improvement could be exploited in stratospheric balloon experiments and, ultimately, in space missions with a telescope of about 20 m focal length, capable of focusing over a broad energy pass-band. We present the latest technological developments of the TRILL (Technological Readiness Increase for Laue Lenses) project, supported by ASI, devoted to the advancement of the technological readiness of Laue lenses. We show the method we developed for preparing suitable b...

MOON What is POSSIBLE - Significant potential for scientific, commercial, and exploratory activities. - Scientific Research: The Moon is an excellent location for astronomical observations due to its lack of atmosphere. It can also provide insights into the early history of the solar system. - Resource Utilization: Mining the Moon for resources such as HELIUM-3 (a potential fuel for nuclear fusion), water ice, and other minerals could support future space missions and possibly even Earth-based applications. - Lunar Base: Establishing a permanent or semi-permanent lunar base could serve as a stepping stone for further space exploration, such as missions to Mars. It could also be a site for scientific research and technology development. - TOURISM: As space travel technology advances, lunar tourism could become a reality, offering unique experiences for people willing to pay for the trip. - Testing New Technologies: The Moon can serve as a testing ground for new space technologies and habitats before deploying them on longer and more challenging missions, like those to Mars. LIFE NOT POSSIBLE - - lack of atmosphere, cannot support breathable air OR protect against harmful solar and cosmic radiation. - no liquid water. ice detected in permanently shadowed craters at the poles. - extreme temperature (120 to -130 C) #moon
