sciforum-066480 | Introduction to a “radical” working hypothesis about a hemisphere-scale impact on Dione (Saturn) | , , | N/A | N/A |
Show Abstract |
||||||||||||||||||||||||||||||||||||
The suspected and proved existence of subsurface oceans on various icy satellites of gas and ice giants such as Callisto, Europa, and Ganymede (Jupiter), Dione, Enceladus and Titan (Saturn), and Triton (Neptune), and the potential that such oceans may harbour life, triggered the renaissance of the research of those planetary bodies (including the ongoing Europa Clipper and JUICE missions). The centre of our research is Dione and its surface characteristics, especially with the focus on the possible relationship between the distribution of certain size craters, linear features and resurfacing processes. The pivot of the study is the region, located westward from the Eurotas and Palatine chasmata spreading approximately between latitude 50° and -50° and longitude -100° to 60° (positive East), roughly at the “transitional hemisphere” between the trailing and leading hemisphere of the moon. The studied area is defined as Intermediate Cratered Terrain, and referred as a region, which was resurfaced at some point during the early history of Dione by a still unknown process, which erased some early generation craters. This study introduces a “radical” working theory about a giant, most likely low-angle impact on the surface of Dione around 4 Ga ago, contributing to the resurfacing of the terrain. Such impact might result in the asymmetrical (“half-ring like”) distribution of secondary craters, observed in the area (i), and the formation of some early component of the Fault Terrain by the dilatation stress field during the modification phase of the impact, and/or later, during the isostatic relaxation of the surface (ii). Along surficial features, the possible formation of a unique Saturn-orbiting impactor population out of the ejectiles (or alternatively, as a “chicken and egg problem”, they might be the source of the impactor) (iii), and the very theoretical formation of the Trojan moon Helene (Dione B) following the accretion of the ejectiles (iv), might be also the results of the hemisphere-scale impact. |

sciforum-067261 | Entanglement --- a higher order symmetry |
Show Abstract |
|||||||||||||||||||||||||||||||||||||||
On October 4, 2022, the Nobel prize for physics was awarded to Alain Aspect, John Clauser and Anton Zeilinger for their experimental work related to quantum entanglement, a controversial topic dating back to a famous research paper published in 1935 by Einstein, Podolsky and Rosen (EPR). Elementary particles sometimes form entangled pairs. For example, two electrons in a singlet state have equal and opposite spin values if placed in a magnetic field, resulting in a sum of zero angular momentum. Consequently, if we were to model these paired electrons on the computer, we might be tempted to imagine two spheres rotating in opposite directions along a fixed axis analogous to the Earth's daily motion. However, we cannot consider elementary particles in this way since there is no fixed axis and their motion cannot be cloned. The axes change as the direction of the magnetic field change. When the spin of each entangled particle is measured in an arbitrary direction, we discover that they have equal and opposite values but until the experiment is carried out there is no preferred spin axis. In contrast to Einstein’s notion of locality, the work of Aspect, Clauser and Zeilinger motivated by Bell’s inequality suggests that quantum entanglement violates “locality.” Unfortunately, for many authors, “non-locality” has come to mean that there is “action at a distance” and that communication is faster than the speed of light. I would like to offer an alternative approach in which “non-locality” neither means faster than light communication nor does it mean that there are hidden parameters in Einstein’s sense. It will be shown that EPR entangled states constitute a higher order symmetry that are SL(2,C) invariant (and hence Lorentz invariant) and that the Pauli Exclusion Principle is a consequence of this new approach to entanglement. |

sciforum-067337 | Supersymmetryc AdS solitons, ground states and phase transitions in maximal gauged supergravity | N/A | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
We present new soliton solutions in a class of four-dimensional supergravity theories. For special values of the parameters, the solutions can be embedded in the gauged maximal N=8 theory and uplifted in the higher-dimensional D=11 theory. We also find BPS soliton configurations, preserving a certain fraction of supersymmetry. Solitons play a special role in classical physics as well as in quantum and string theory, determining a richer structure of the full non-perturbative regime. This different class of exact solutions can be obtained from a double Wick rotation of a former black hole configuration, the new solutions characterizing a regular spacetime configuration devoid of horizons. |

sciforum-067395 | Results and Prospects of the Hellenic Open University air shower array | , , | N/A |
Show Abstract |
|||||||||||||||||||||||||||||||||||||
Astroneu is an array of autonomous Extensive Air Shower detection stations deployed at the Hellenic Open University (HOU) campus on the outskirts of Patras in western Greece. In the first phase of operation 9 scintillators detectors and 3 Radio Frequency (RF) antennas have been installed and operated at the site. The detector units were arranged in three autonomous stations each consisting of three scintillator detectors (SDM) and one RF antenna. In the second phase of operation 3 more antennas were deployed at one station in order to study the correlation of the RF signals from 4 antennas subject to the same shower event. In this report we present the standard offline SDM-RF data and simulations analysis, the main research results concerning the reconstruction of the EAS parameters as well as the prospects of a new compact array that will be deployed by 2023. |

S1. Gravitation and Cosmology
Our current understanding of gravitational physics is being put to the test by numerous observational and experimental efforts aimed at different scales and field intensities, ranging from submillimeter physics to extreme compact objects, galaxies, and cosmology. It is now evident that the large-scale structure of the universe cannot be fully understood without a clear description of its microscopic (quantum) properties and symmetries and that a fully satisfactory theory requires a delicate equilibrium between many different scenarios. Understanding the nature and composition of compact objects is crucial for better understanding the most energetic astrophysical phenomena and the origin and evolution of structures. Additionally, a large number of cosmological observations seem to be implying that the very expansion of the universe predicted by the standard cosmological model shows significant tensions between different probes. Clarifying these and other cosmological tensions, as well as a number of large-angular-scale anomalies observed in the cosmic microwave background fluctuations, might lead to interesting new physics.
Progress in these challenging endeavors can only be accomplished by bringing together experts in all fields of gravitation and cosmology to share their ideas and findings in a relaxed and collaborative atmosphere. The second edition of Electronic Conference on the Universe (ECU 2023) hopes to provide such an atmosphere and to contribute to the exciting efforts in theoretical and observational cosmology and gravitational physics.
We hope that this new edition of ECU will bring together novel results on a variety of topics including weak and strong gravity, stellar models, classical and quantum aspects of black holes and other compact objects, gravitational waves, early- and late-time cosmology, and cosmological tensions and anomalies.

S8. Stellar and Solar Physics
Studying the Sun-as-a-star analog and the extension to stellar environments is one of the main building blocks of our understanding of astrophysics. This is because the proximity of the Sun to Earth allowed the in-depth monitoring and modeling of our host star and its effects and impact on our planetary system. We aim to bring together the Stellar and Solar Physics communities and enhance synergies among these two research areas.
The session brings together scientists from all fields of research related to solar, stellar, astrophysical, and exoplanetary sciences. It will allow the sharing of expertise amongst researchers working on different aspects of this interdisciplinary scientific field, allowing showcases of recent advancements in the field of specialization.
We solicit contributions related but not limited to:
- Modeling stellar astrospheres and the corresponding energy-dependent cosmic ray flux;
- Modeling stellar Coronal Mass Ejections (CMEs);
- Evaluation and quantification of the solar UV-, X-ray, and energetic particle flux relationships and their extension to the stellar environment;
- The imprint of the stellar radiation field by modeling the magnetospheric transport and particle interactions within (exo)planetary atmospheres;
- Atmospheric modeling studies of climate and (biosignature) photochemistry and the influence of stellar activity.
Keywords: stellar radiation environment, CMEs, solar/stellar flares, habitability.
