  • A 3D view of dwarf galaxies with Gaia and VLT/FLAMES. I. The Sculptor dwarf spheroidal
    We present a new homogeneous survey of VLT/FLAMES LR8 line-of-sight radial velocities (v los) for 1604 resolved red giant branch stars in the Sculptor dwarf spheroidal galaxy. In addition, we provide reliable Ca II triplet metallicities, [Fe/H], for 1339 of these stars. From this combination of new observations (2257 individual spectra) with ESO

  • 3D Spectroscopy with GTC-MEGARA of the Triple AGN Candidate in SDSS J102700.40+174900.8
    Triple-active galactic nucleus (AGN) systems are expected to be the result of the hierarchical model of galaxy formation. Since there are very few of them confirmed as such, we present the results of a new study of the triple AGN candidate SDSS J102700.40+174900.8 (center nucleus) through observations with the GTC-MEGARA Integral Field Unit. 1D and

  • EXPLORING THE COSMOS THROUGH A LENS: SEARCHING FOR STRONGLY-LENSED SUPERNOVAE IN TIME-DOMAIN SURVEYS
    La constante de Hubble (H0) es un parámetro crítico en cosmología que define propiedades esenciales del universo, como su tamaño, edad, tasa de expansión y densidad crítica. A pesar de su importancia, determinar un valor preciso para H0 sigue siendo un tema de debate en el campo de la cosmología. Se han utilizado varios métodos para medir H0 dentro

  • X-ray properties of the white dwarf pulsar eRASSU J191213.9−441044
    We report X-ray observations of the newly discovered pulsating white dwarf eRASSU J191213.9−441044 with Spectrum Roentgen Gamma and eROSITA (SRG/eROSITA) and XMM-Newton. The new source was discovered during the first eROSITA all-sky survey at a flux level of f X(0.2 − 2.3 keV) = 3.3 × 10 −13 erg cm −2 s −1 and found to be spatially coincident with

  • Uncertainty-aware blob detection with an application to integrated-light stellar population recoveries
    Context. Blob detection is a common problem in astronomy. One example is in stellar population modelling, where the distribution of stellar ages and metallicities in a galaxy is inferred from observations. In this context, blobs may correspond to stars born in situ versus those accreted from satellites, and the task of blob detection is to

  • Ultracool dwarfs candidates based on 6 yr of the Dark Energy Survey data
    We present a sample of 19 583 ultracool dwarf candidates brighter than z ≤23 selected from the Dark Energy Survey DR2 coadd data matched to VHS DR6, VIKING DR5, and AllWISE covering ~ 480 deg 2. The ultracool candidates were first pre-selected based on their (i-z), (z-Y), and (Y-J) colours. They were further classified using a method that compares
