A possible misaligned orbit for the young planet AU Mic c
H. Yu, Z. Garai, M. Cretignier +98
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measur…
Euclid: Field-level inference of primordial non-Gaussianity and cosmic initial conditions
A. Andrews, J. Jasche, G. Lavaux +147
A primary target of the \Euclid space mission is to constrain early-universe physics by searching for deviations from a primordial Gaussian random field. A significant detection of…
CHEOPS observations confirm nodal precession in the WASP-33 system
A. M. S. Smith, Sz. Csizmadia, V. Van Grootel +86
Aims: We aim to observe the transits and occultations of WASP-33b, which orbits a rapidly-rotating Scuti pulsator, with the goal of measuring the orbital obliquity via the grav…
Characterization of seven transiting systems including four warm Jupiters from SOPHIE and TESS
N. Heidari, G. H'ebrard, E. Martioli +65
We present the study of seven systems, three of which TOI-2295, TOI-2537, and TOI-5110 are newly discovered planetary systems. Through the analysis of TESS photometry, SOPHIE radia…
Radii, masses, and transit-timing variations of the three-planet system orbiting the naked-eye star TOI-396
A. Bonfanti, I. Amateis, D. Gandolfi +38
TOI-396 is an F6V star () orbited by three transiting planets. The orbital periods of the two innermost planets are close to the 5:3 commensurability ( d…
A joint effort to discover and characterize two resonant mini Neptunes around TOI-1803 with TESS, HARPS-N and CHEOPS
T. Zingales, L. Malavolta, L. Borsato +130
We present the discovery of two mini Neptunes near a 2:1 orbital resonance configuration orbiting the K0 star TOI-1803. We describe their orbital architecture in detail and suggest…
Gravitational waves and galaxies cross-correlations: a forecast on GW biases for future detectors
Stefano Zazzera, José Fonseca, Tessa Baker +1
Gravitational waves (GWs) have rapidly become important cosmological probes since their first detection in 2015. As the number of detected events continues to rise, upcoming instru…
Robust heteroclinic cycles in pluridimensions
Sofia B. S. D. Castro, Alastair M. Rucklidge
Heteroclinic cycles are sequences of equilibria along with trajectories that connect them in a cyclic manner. We investigate a class of robust heteroclinic cycles that does not sat…
Importance of modelling the nebular continuum in galaxy spectra
Henrique Miranda, Ciro Pappalardo, José Afonso +7
The neglect of modelling both stellar and nebular emission significantly affects the derived physical properties of galaxies, particularly those with high star formation rates. Whi…
Is cosmological data suggesting a nonminimal coupling between matter and gravity?
Miguel Barroso Varela, Orfeu Bertolami
Theoretical predictions from a modified theory of gravity with a nonminimal coupling between matter and curvature are compared to data from recent cosmological surveys. We use type…
High strehl and high contrast for the ELT instrument METIS -- Final design, implementation, and predicted performance of the single-conjugate adaptive optics system
Markus Feldt, Thomas Bertram, Carlos Correia +8
The Mid-infrared ELT Imager and Spectrograph (METIS) is a first-generation instrument for the Extremely Large Telescope (ELT), Europe's next-generation 39 m ground-based telescope…
Large-Scale Stellar Age-Velocity Spiral Pattern in NGC 4030
Iris Breda, Glenn van de Ven, Sabine Thater +11
The processes driving the formation and evolution of late-type galaxies (LTGs) continue to be a debated subject in extragalactic astronomy. Investigating stellar kinematics, especi…
Formal Simulation and Visualisation of Hybrid Programs
Pedro Mendes, Ricardo Correia, Renato Neves +1
The design and analysis of systems that combine computational behaviour with physical processes' continuous dynamics - such as movement, velocity, and voltage - is a famous, challe…
Assessing the processes behind planet engulfment and its imprints
B. M. T. B. Soares, V. Adibekyan, C. Mordasini +5
Throughout a planetary system's formation evolution, some of the planetary material may end up falling into the host star and be engulfed by it, leading to a potential variation of…
Temperature dependence of charge transport in the half-filled 1D Hubbard model
J. M. P. Carmelo, P. D. Sacramento
The use of hydrodynamic transport theory seems to indicate that the charge diffusion constant D of the one-dimensional (1D) half-filled Hubbard model, whose Drude weight vanishes,…
A close outer companion to the ultra-hot Jupiter TOI-2109 b?
J. -V. Harre, A. M. S. Smith, S. C. C. Barros +86
Hot Jupiters with close-by planetary companions are rare, with only a handful of them having been discovered so far. This could be due to their suggested dynamical histories, leadi…
Studying Binary Systems in Omega Centauri with MUSE. I. Detection of Spectroscopic Binaries
F. Wragg, S. Kamann, S. Saracino +6
NGC 5139 ( Cen), is the closest candidate of a Nuclear Star Cluster that has been stripped of its host galaxy in the Milky Way. Despite extensive studies through the last decade…
