Jamming with tunable roughness
(2020) [Journal article]We introduce a new model to study the effect of surface roughness on the jamming transition. By performing numerical simulations, we show that for a smooth surface, the jamming transition density and the contact number at ... -
Javanella sanfordae, a new cytheridae (crustacea: ostracoda) spcies with a discussion on the validity of the genus Javanella kingma
(2007) [Journal article]Javanella sanfordae, uma nova espécie de ostracode da família Cytheridae (Crustacea, Ostracoda), é aqui descrita e ilustrada. Entre os poucos registros fósseis e recentes de Javanella este é o primeiro fora da região do ... -
A jet-driven bipolar outflow in NGC 1125
(2025) [Journal article]To study the role of the feedback from the active galactic nucleus (AGN) in the evolution of its host galaxy, we need observational constraints on 100 pc scales. We used the Gemini near-infrared integral field spectrograph ... -
Jet fragmentation transverse momentum distributions in pp and p-Pb collisions at √s, √sNN = 5.02 TeV
(2021) [Journal article]Jet fragmentation transverse momentum (jT) distributions are measured in proton-proton (pp) and proton-lead (p-Pb) collisions at √ sNN = 5.02 TeV with the ALICE experiment at the LHC. Jets are reconstructed with the ALICE ... -
Jet fragmentation transverse momentum measurements from di-hadron correlations in √s=7 TeV pp and and √sNN=5.02 TeV p–Pb collisions
(2019) [Journal article]The transverse structure of jets was studied via jet fragmentation transverse momentum (jT) distributions, obtained using two-particle correlations in proton-proton and proton-lead collisions, measured with the ALICE ... -
Jet-hadron correlations measured relative to the second order event plane in Pb-Pb collisions at √sNN = 2.76 TeV
(2020) [Journal article]The quark gluon plasma produced in ultrarelativistic heavy-ion collisions at the Large Hadron Collider (LHC) can be studied by measuring the modifications of jets formed by hard scattered partons which interact with the ... -
Jet properties in PbPb and pp collisions at √sNN = 5.02 TeV
(2018) [Journal article]Abstract: Modi cations of the properties of jets in PbPb collisions, relative to those in pp collisions, are studied at a nucleon-nucleon center-of-mass energy of p sNN = 5:02TeV via correlations of charged particles with ... -
Jet shapes of isolated photon-tagged jets in Pb-Pb and pp collisions at √sNN=5.02 TeV

Jogos lógicos de tabuleiro : imersão no território escolar
(2015) [Journal article]Este artigo analisa os dados da primeira fase da pesquisa Jogos Lógicos de Tabuleiro: imersão no território escolar, que propõe um estreito vínculo entre a extensão universitária e o ensino na promoção de encontros de ... -
J-PLUS : a catalogue of globular cluster candidates around the M 81/M 82/NGC 3077 triplet of galaxies
(2022) [Journal article]Globular clusters (GCs) are proxies of the formation assemblies of their host galaxies. However, few studies exist targeting GC systems of spiral galaxies up to several effective radii. Through 12-band Javalambre Photometric ... -
J-PLUS : analysis of the intracluster light in the Coma cluster
(2019) [Journal article]Context. 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 individual galaxies. Previous studies of ... -
J-PLUS: a wide-field multi-band study of the M 15 globular cluster : evidence of multiple stellar populations in the RGB
(2019) [Journal article]Context. As a consequence of internal and external dynamical processes, Galactic globular clusters (GCs) have properties that vary radially. Wide-field observations covering the entire projected area of GCs out to their ... -
J-PLUS : detecting and studying extragalactic globular clusters
(2022) [Journal article]Context. Extragalactic globular clusters (GCs) are key objects in studies of galactic histories. The advent of wide-field surveys, such as the Javalambre Photometric Local Universe Survey (J-PLUS), offers new possibilities ... -
J-PLUS : identification of low-metallicity stars with artificial neural networks using SPHINX
(2019) [Journal article]Context. We present a new methodology for the estimation of stellar atmospheric parameters from narrow- and intermediate-band photometry of the Javalambre Photometric Local Universe Survey (J-PLUS), and propose a method ... -
J-PLUS : impact of bars on quenching timescales in nearby green valley disc galaxies
(2019) [Journal article]Context. Between the blue cloud and the red sequence peaks on the galaxy colour–magnitude diagram there is a region sparsely populated by galaxies called the green valley. In a framework where galaxies mostly migrate on ... -
J-PLUS : measuring Hα emission line fluxes in the nearby universe
(2019) [Journal article]n this paper we aim to validate a methodology designed to obtain Hα emission line fluxes from J-PLUS photometric data. J-PLUS is a multi narrow-band filter survey carried out with the 2 deg2 field of view T80Cam camera, ... -
J-PLUS : morphological star/galaxy classification by PDF analysis
(2019) [Journal article]Aims. Our goal is to morphologically classify the sources identified in the images of the J-PLUS early data release (EDR) as compact (stars) or extended (galaxies) using a dedicated Bayesian classifier. Methods. J-PLUS ...
