Significados del concepto de interacción gravitatoria en estudiantes de nivel polimodal y puesta en práctica de una propuesta didáctica respecto a dicho concepto
… level use to assign meanings to the concept of gravitational interaction and to design and implement a didactical proposal that incorporates such a concept as a linking principle of the physics contents studied at that school level. Initially, some diagnostic studies were carried out: (a) ideas …

Listening to the Universe through indirect detection
… observations of dark matter, through its gravitational interaction, can be exploited to determine the most promising locations on the sky to observe a particle dark matter signal. On the other, I demonstrate that refined theoretical calculations of the expected dark matter interactions can …

Significance of Specific Force Models in Two Applications: Solar Sails to Sun-Earth L4/L5 and GRAIL Data Analysis Suggesting Lava Tubes and Buried Craters on the Moon
In the trajectory design process, gravitational interaction between the bodies of interest plays a key role in developing the over-arching force model. However, non-gravitational forces, such as solar radiation pressure (SRP), can significantly influence the motion of a spacecraft. Incorporating …

Neutral hydrogen observations of spiral and irregular galaxies
… suggests that there has been a planar tidal interaction between these two galaxies. NGG 2805, NGC 2814, NGG 2820 and 10 2458 form a compact group of galaxies of which NGC 2805 is the brightest. HI was detected in all except NGC 2814, and there is good evidence for a HI bridge linking NGC 2820 …

Investigating the parameter space of viable models for f(R) gravity
… that this class is still a candidate for the gravitational interaction.

The orbital dynamics and long-term stability of planetary systems
… multi-planet systems leads to strong dynamical interactions that imprint themselves on the transit light curve as transit timing variations (TTVs). By modeling the orbital evolution of these planetary systems, one can fit the observed variations and strongly constrain the masses and orbits of …

Asymptotically Safe Gravity: from spacetime foliation to cosmology
… a more fundamental quantum theory for the gravitational interaction. However, as it is well known, the quantization of General Relativity leads to a (perturbatively) non-renormalizable theory. The Asymptotic Safety scenario for Quantum Gravity provides a natural mechanism for constructing a …

Interferometric experiments towards advanced gravitational wave detectors
… later extended this concept to include gravitational interactions, and Eddington's timely measurements of stellar positions during a solar eclipse in 1919 confirmed that gravity's effect on spacetime is both real and entirely physical -- not merely a mathematical curiosity. With the …

Planet formation and evolution in protoplanetary disc
… evolution as a consequence of disc-planet interaction from a numerical and theoretical perspective. In the core accretion scenario, planets form in protoplanetary discs by growing the initial μm-sized dust grains up to the size of a planet. The aerodynamic interaction between the dust …

Towards the formation of a forward-boosted beam of neutral antihydrogen for gravitational studies
… of general relativity, postulates that the gravitational charge of antimatter should be equal to its inertial mass, as it is for matter. However, some physics beyond the Standard Model (BSM) theories admit a difference in the gravitational properties of matter and antimatter [8]. Measuring …

Clestial harmonics - Applications of Angular Power Spectra to Problems in Astroparticle and Cosmological Physics
… of additional fields or modifications of the gravitational interaction. Taking a rather agnostic stance, oriented in the first place to properly measuring the relevant quantities, we build upon a number of previous works, in particular, on (García-García et al., 2021; Sailer et al., 2025a), …
