Role of predator-prey reversal in Rock-Paper-Scissors models
P. P. Avelino, B. F. de Oliveira, R. S. Trintin
In this letter we consider a single parameter generalization of the standard three species Rock-Paper-Scissors (RPS) model allowing for predator-prey reversal. This model, which sh…
Evidence of structural discontinuities in the inner core of red-giant stars
Mathieu Vrard, Margarida S. Cunha, Diego Bossini +3
Red giants are stars in the late stages of stellar evolution. Because they have exhausted the supply of hydrogen in their core, they burn the hydrogen in the surrounding shell. Onc…
Discovery of TOI-1260d and the characterisation of the multi-planet system
Kristine W. F. Lam, J. Cabrera, M. J. Hooton +83
We report the discovery of a third planet transiting the star TOI-1260, previously known to host two transiting sub-Neptune planets with orbital periods of 3.127 and 7.493 days, re…
TESS Hunt for Young and Maturing Exoplanets (THYME) IX: a 27 Myr extended population of Lower-Centaurus Crux with a transiting two-planet system
Mackenna L. Wood, Andrew W. Mann, Madyson G. Barber +35
We report the discovery and characterization of a nearby (~ 85 pc), older (27 +/- 3 Myr), distributed stellar population near Lower-Centaurus-Crux (LCC), initially identified by se…
Improving machine learning-derived photometric redshifts and physical property estimates using unlabelled observations
A. Humphrey, P. A. C. Cunha, A. Paulino-Afonso +5
In the era of huge astronomical surveys, machine learning offers promising solutions for the efficient estimation of galaxy properties. The traditional, `supervised' paradigm for t…
The MUSE Hubble Ultra Deep Field surveys: Data release II
Roland Bacon, Jarle Brinchmann, Simon Conseil +30
We present the second data release of the MUSE Hubble UDF surveys, which includes the deepest spectroscopic survey ever performed. The MUSE data, with their 3D content, amazing dep…
An investigation of the star-forming main sequence considering the nebular continuum emission at low-z
Henrique Miranda, Ciro Pappalardo, Polychronis Papaderos +7
The code FADO is the first publicly available population spectral synthesis tool that treats the contribution from ionised gas to the observed emission self-consistently. We study…
Optimal control of nonlocal continuity equations: numerical solution
Roman Chertovskih, Nikolay Pogodaev, Maxim Staritsyn
The paper addresses an optimal ensemble control problem for nonlocal continuity equations on the space of probability measures. We admit the general nonlinear cost functional, and…
From Bloch Oscillations to a Steady-State Current in Strongly Biased Mesoscopic Devices
J. M. Alendouro Pinho, J. P. Santos Pires, Simão M. João +2
It has long been known that quantum particles moving in a periodic lattice and subject to a constant force field undergo an oscillatory motion that is referred to as Bloch Oscillat…
Higher-Point Integrands in N=4 super Yang-Mills Theory
Till Bargheer, Thiago Fleury, Vasco Gonçalves
We compute the integrands of five-, six-, and seven-point correlation functions of twenty-prime operators with general polarizations at the two-loop order in N=4 super Yang-Mills t…
Benchmarking Edge Computing Devices for Grape Bunches and Trunks Detection using Accelerated Object Detection Single Shot MultiBox Deep Learning Models
Sandro Costa Magalhães, Filipe Neves Santos, Pedro Machado +2
Purpose: Visual perception enables robots to perceive the environment. Visual data is processed using computer vision algorithms that are usually time-expensive and require powerfu…
Chronic pain patient narratives allow for the estimation of current pain intensity
Diogo A. P. Nunes, Joana Ferreira-Gomes, Daniela Oliveira +4
Chronic pain is a multi-dimensional experience, and pain intensity plays an important part, impacting the patients emotional balance, psychology, and behaviour. Standard self-repor…
Omnidirectional robot modeling and simulation
Sandro Costa Magalhães, António Paulo Moreira, Paulo Costa
A robot simulation system is a basic need for any robotics application. With it, developers' teams of robots can test their algorithms and make initial calibrations without risk of…
A sub-Neptune planet around TOI-1695 discovered and characterized with SPIRou and TESS
F. Kiefer, G. Hébrard, E. Martioli +39
TOI-1695 is a V-mag=13 M-dwarf star from the northern hemisphere at 45pc from the Sun, around which a 3.134-day periodic transit signal from a super-Earth candidate was identif…
Examining the orbital decay targets KELT-9 b, KELT-16 b and WASP-4 b, and the transit-timing variations of HD 97658 b
J. -V. Harre, A. M. S. Smith, S. C. C. Barros +87
Tidal orbital decay is suspected to occur especially for hot Jupiters, with the only observationally confirmed case of this being WASP-12 b. By examining this effect, information o…
Stellar signal components seen in HARPS and HARPS-N solar radial velocities
K. Al Moulla, X. Dumusque, P. Figueira +3
Context. Radial velocity (RV) measurements induced by the presence of planets around late-type stars are contaminated by stellar signals that are of the order of a few meters per s…
55 Cancri e's occultation captured with CHEOPS
B. -O. Demory, S. Sulis, E. Meier Valdes +73
Past occultation and phase-curve observations of the ultra-short period super-Earth 55 Cnc e obtained at visible and infrared wavelengths have been challenging to reconcile with a…
Redshift drift cosmography with ELT and SKAO measurements
B. A. R. Rocha, C. J. A. P. Martins
Mapping the expansion history of the universe is a compelling task of physical cosmology, especially in the context of the observational evidence for the recent acceleration of the…
A 4 Gyr M-dwarf Gyrochrone from CFHT/MegaPrime Monitoring of the Open Cluster M67
Ryan Dungee, Jennifer van Saders, Eric Gaidos +5
We present stellar rotation periods for late K- and early M-dwarf members of the 4 Gyr old open cluster M67 as calibrators for gyrochronology and tests of stellar spin-down models.…
Coupled minimal models revisited
António Antunes, Connor Behan
We study coupled unitary Virasoro minimal models in the large rank () limit. In large perturbation theory, we find two non-trivial IR fixed points which e…
