Gaia Focused Product Release: A catalogue of sources around quasars to search for strongly lensed quasars
(EDP Sciences, 2024-05-17)[Abstract]: Context. Strongly lensed quasars are fundamental sources for cosmology. The Gaia space mission covers the entire sky with the unprecedented resolution of 0.18″ in the optical, making it an ideal instrument to ... -
Gaia Focused Product Release: Asteroid orbital solution: Properties and assessment
(EDP Sciences, 2023)[Abstract] Context. We report the exploitation of a sample of Solar System observations based on data from the third Gaia Data Release (Gaia DR3) of nearly 157 000 asteroids. It extends the epoch astrometric solution over ... -
Gaia Focused Product Release: Radial velocity time series of long-period variables
(EDP Sciences, 2023)[Abstract] Context. The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocity data planned with ... -
Gaia Focused Product Release: Sources from Service Interface Function image analysis: Half a million new sources in omega Centauri
(EDP Sciences, 2023)[Abstract] Context. Gaia’s readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for nine selected regions ... -
Gaia Focused Product Release: Spatial distribution of two diffuse interstellar bands
(EDP Sciences, 2023)[Abstract] Diffuse interstellar bands (DIBs) are absorption features seen in optical and infrared spectra of stars and extragalactic objects that are probably caused by large and complex molecules in the galactic interstellar ... -
GUASOM: An Adaptive Visualization Tool for Unsupervised Clustering in Spectrophotometric Astronomical Surveys
(Springer, 2022)[Abstract] We present an adaptive visualization tool for unsupervised classification of astronomical objects in a Big Data context such as the one found in the increasingly popular large spectrophotometric sky surveys. ... -
Methodology for obtaining the relative orbit and individual masses of Gaia astrometric binaries
(EDP Sciences, 2024-02)[Abstract]: Context. The recent Gaia Data Release 3 has revealed a catalogue of more than eight hundred thousand binary systems. The release provides orbital solutions for half of the systems, with the majority of them ... -
Oil spill segmentation in SAR images using convolutional neural networks. A comparative analysis with clustering and logistic regression algorithms
(Elsevier Ltd, 2019-11)[Abstract]: Synthetic aperture radar (SAR) images are a valuable source of information for the detection of marine oil spills. For their effective analysis, it is important to have segmentation algorithms that can delimit ... -
On the estimation of stellar parameters with uncertainty prediction from Generative Artificial Neural Networks: application to Gaia RVS simulated spectra
(EDP Sciences, 2016-10)[Abstract]: Aims. We present an innovative artificial neural network (ANN) architecture, called Generative ANN (GANN), that computes the forward model, that is it learns the function that relates the unknown outputs (stellar ... -
Personalized Virtual Reality Environments for Intervention with People with Disability
(MDPI, 2022)[Abstract] Background: Virtual reality (VR) is a technological resource that allows the generation of an environment of great realism while achieving user immersion. The purpose of this project is to use VR as a complementary ... -
Phosphorus-Rich Stars With Unusual Abundances Are Challenging Theoretical Predictions
(Nature Publishing Group, 2020-08-04)[Abstract] Almost all chemical elements have been made by nucleosynthetic reactions in various kind of stars and have been accumulated along our cosmic history. Among those elements, the origin of phosphorus is of extreme ... -
Planetary Nebulae in Gaia EDR3: Central Star Identification, Properties, and Binarity
(EDP Science, 2021)[Abstract] Context. The Gaia Early Data Release 3 (EDR3), published in December 2020, features improved photometry and astrometry compared to that published in the previous DR2 file and includes a substantially larger ... -
QKDNetSim+: Improvement of the quantum network simulator for NS-3
(Elsevier, 2024)[Abstract]: The first Quantum Key Distribution (QKD) networks are currently being deployed, but the implementation cost is still prohibitive for most researchers. As such, there is a need for realistic QKD network simulators. ... -
Safety and Traceability in Patient Healthcare through the Integration of RFID Technology for Intravenous Mixtures in the Prescription-Validation-Elaboration-Dispensation-Administration Circuit to Day Hospital Patients
This work presents the integration of the RFID technology with the aim of ensuring the traceability of patients and minimization of adverse events during the process of prescription-validation-elaboration-dispensation-ad ... -
Solid confirmation of the broad DIB around 864.8nm using stacked Gaia–RVS spectra
(EDP Sciences, 2022)[Abstract]: Context. Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia–RVS spectral window between 846 and 870 nm contains few DIBs, ... -
Stellar ages, masses, extinctions, and orbital parameters based on spectroscopic parameters of Gaia DR3
(EDP Sciences, 2023)[Abstract]: Gaia's third data release provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than 5 million targets. When combined with the astrometric data, these ... -
The cerium content of the Milky Way as revealed by Gaia DR3 GSP-Spec abundances
(EDP Sciences, 2023)[Abstract]: The recent Gaia third data release contains a homogeneous analysis of millions of high-quality Radial Velocity Spectrometer (RVS) stellar spectra by the GSP-Spec module. This led to the estimation of millions ... -
The Development of an RFID Solution to Facilitate the Traceability of Patient and Pharmaceutical Data
