Gaia Data Release 3: The extragalactic content
(EDP Sciences, 2023-06)
[Abstract]: The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as an all-sky multi-epoch survey, Gaia also observes ...
Gaia Data Release 3: Astrophysical parameters inference system (Apsis). I. Methods and content overview
(EDP Sciences, 2023-06)
[Abstract]: Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release, and were produced by the Astrophysical parameters inference system ...
Discovery of a dormant 33 solar-mass black hole in pre-release Gaia astrometry
(EDP Sciences, 2024)
[Abstract] Context. Gravitational waves from black-hole (BH) merging events have revealed a population of extra-galactic BHs residing in short-period binaries with masses that are higher than expected based on most stellar ...
Building-Scale Wastewater-Based Epidemiology for SARS-CoV-2 Surveillance at Nursing Homes in A Coruña, Spain
(MDPI, 2023-11)
[Abstract] Wastewater-based epidemiology (WBE) has become an effective tool in the surveillance of
infectious diseases such as COVID-19. In this work, we performed a brief study of monitoring the
SARS-CoV-2 viral load ...
Navigating planar topologies in near-optimal space and time
(Elsevier B.V., 2023-02)
[Abstract]: We show that any embedding of a planar graph can be encoded succinctly while efficiently answering a number of topological queries near-optimally. More precisely, we build on a succinct representation that ...
Faster compressed quadtrees
(Elsevier B.V., 2023-02)
[Abstract]: Real-world point sets tend to be clustered, so using a machine word for each point is wasteful. In this paper we first show how a compact representation of quadtrees using O(1) bits per node can break this bound ...
Bolivianas en Argentina, brasileñas en Portugal y colombianas en España: Un análisis poscolonial de las trayectorias migratorias de las mujeres de Latinoamérica
(Instituto Universitario de Estudios sobre Migraciones | Universidad Pontificia Comillas, 2022)
[Resumen] Esta investigación analiza comparativamente las migraciones de las mujeres bolivianas en Argentina, las brasileñas en Portugal y las colombianas en España. Desde una aproximación interseccional que ubicamos en ...
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: 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 ...
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 ...
