The S-PLUS: a star/galaxy classification based on a Machine Learning approach
M. V. Costa-Duarte, L. Sampedro, A. Molino +32
We present a star/galaxy classification for the Southern Photometric Local Universe Survey (S-PLUS), based on a Machine Learning approach: the Random Forest algorithm. We train the…
J-PLUS: the impact of bars on quenching time-scales in nearby green valley disc galaxies
J. P. Nogueira-Cavalcante, R. Dupke, P. Coelho +28
In a framework where galaxies mostly migrate on the colour-magnitude diagram from star-forming to quiescent, the green valley is considered a transitional galaxy stage. The details…
J-PLUS: Discovery and characterisation of ultracool dwarfs using Virtual Observatory tools
E. Solano, E. L. Martín, J. A. Caballero +20
Ultracool dwarfs (UCDs) are objects with spectral types equal or later than M7. Most of them have been discovered using wide-field imaging surveys. The Virtual Observatory (VO) has…
J-PLUS: analysis of the intracluster light in the Coma cluster
Y. Jiménez-Teja, R. A. Dupke, R. Lopes de Oliveira +19
The intracluster light (ICL) is a luminous component of galaxy clusters composed of stars that are gravitationally bound to the cluster potential but do not belong to the individua…
J-PLUS: measuring emission line fluxes in the nearby universe
R. Logroño-García, G. Vilella-Rojo, C. López-Sanjuan +29
In the present paper we aim to validate a methodology designed to extract the Halpha emission line flux from J-PLUS photometric data. J-PLUS is a multi narrow-band filter survey ca…
J-PLUS: 2-D analysis of the stellar population in NGC 5473 and NGC 5485
I. San Roman, P. Sánchez-Blázquez, A. J. Cenarro +23
The spatial variations of stellar population properties within a galaxy are intimately related to their formation process. Therefore, spatially resolved studies of galaxies are ess…
J-PLUS: The Javalambre Photometric Local Universe Survey
A. J. Cenarro, M. Moles, D. Cristóbal-Hornillos +119
J-PLUS is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the Observatorio…
Is there a propeller neutron star in Cas?
Myron A. Smith, R. Lopes de Oliveira, C. Motch
Cas is the prototype of a small population of B0-B1.5 III-V classical Be (cBe) stars that emit anomalous and hard X-rays with a unique array of properties. Cas is known to…
Exploring the connection between the stellar wind and the non-thermal emission in LS 5039
V. Bosch-Ramon, C. Motch, M. Ribo +5
LS 5039 has been observed with several X-ray instruments so far. The source presents X-ray variability at orbital timescales in flux and photon index. The system harbors an O-type…
Discovery of a cluster of galaxies behind the Milky Way: X-ray and optical observations
R. Lopes de Oliveira, G. B. Lima Neto, C. Mendes de Oliveira +2
We report the discovery of Cl 2334+48, a rich cluster of galaxies in the Zone of Avoidance, identified in public images from the XMM-Newton archive. We present the main properties…
