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 ... -
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 ... -
J-PLUS : on the identification of new cluster members in the double galaxy cluster A2589 and A2593 using PDFs
(2019) [Journal article]Aims. We aim to use multiband imaging from the Phase-3 Verification Data of the J-PLUS survey to derive accurate photometric redshifts (photo-z) and look for potential new members in the surroundings of the nearby galaxy ...
