Spacetime closedness theorem for homogeneous Lorentzian foliations
Robert Monjo
Motivated by the geometric interpretation of spatially homogeneous cosmological models, we formulate a spacetime closedness theorem directly at the Lorentzian level. A classical sp…
Gas-rich ultra-diffuse galaxies: alleviating the MOND tension with hyperconical modified gravity
Robert Monjo
Gas-rich ultra-diffuse galaxies (UDGs) are an unusually sharp test for gravity models tied to the baryonic Tully--Fisher relation because several systems appear to rotate too slowl…
Hadronic lensing
Fabrizio Canfora, Cristóbal Corral, Borja Diez
We introduce an analytic approach to study gravitational lensing in the presence of a distribution of hadrons. The situation is analogous to the propagation of photons in a medium…
Constraining the size, shape, and albedo of the large Trans-Neptunian Object (28978) Ixion with multi-chord stellar occultations
Y. Kilic, F. Braga-Ribas, C. L. Pereira +81
Trans-Neptunian objects (TNOs) are among the most primitive remnants of the early Solar System, and constraining their sizes, shapes, albedos, and surface properties is essential f…
Generation of gravitating solutions with Baryonic charge from Einstein-Scalar-Maxwell seeds
Fabrizio Canfora, Anibal Neira, Seung Hun Oh
We establish, for the first time, an exact correspondence between Einstein-scalar-Maxwell theory and gauged Skyrme-Maxwell-Einstein models in (3+1) dimensions. By constructing the…
On deformed pathways: CFT to CCFT
Aritra Banerjee, Pulastya Parekh, Robin Raj
We discuss the marginal deformation of massless scalar field theories in two dimensions from a dynamical perspective. The operator flow equations for such de…
