Hybrid stars with large strange quark cores
Márcio Ferreira, Renan Câmara Pereira, Constança Providência
The possible existence of hybrid stars is studied using several multi-quark interaction channels. The hadronic phase consists of an equation of state (EoS) with presently accepted…
Machine-Learning Love: classifying the equation of state of neutron stars with Transformers
Gonçalo Gonçalves, Márcio Ferreira, João Aveiro +4
The use of the Audio Spectrogram Transformer (AST) model for gravitational-wave data analysis is investigated. The AST machine-learning model is a convolution-free classifier that…
Extracting nuclear matter properties from the neutron star matter equation of state using deep neural networks
Márcio Ferreira, Valéria Carvalho, Constança Providência
The extraction of the nuclear matter properties from neutron star (NS) observations is nowadays an important issue, in particular, the properties that characterize the symmetry ene…
Identification of Binary Neutron Star Mergers in Gravitational-Wave Data Using YOLO One-Shot Object Detection
João Aveiro, Felipe F. Freitas, Márcio Ferreira +4
We demonstrate the application of the YOLOv5 model, a general purpose convolution-based single-shot object detection model, in the task of detecting binary neutron star (BNS) coale…
Relativistic description of dense matter equation of state and compatibility with neutron star observables: a Bayesian approach
Tuhin Malik, Márcio Ferreira, B. K. Agrawal +1
The general behavior of the nuclear equation of state (EOS), relevant for the description of neutron stars (NS), is studied within a Bayesian approach applied to a set of models ba…
Determination of the symmetry energy from the neutron star equation of state
Pedro Barata de Tovar, Márcio Ferreira, Constança Providência
We analyze the uncertainties introduced in the determination of the neutron star matter proton fraction, in a range of densities close to the saturation density, if the cold -eq…
