(Oxford University Press, 2016)
      We study the stellar properties of 44 face-on spiral galaxies from the Calar Alto Legacy Integral Field Area survey via full spectrum fitting techniques. We compare the age profiles with the surface brightness distribution ...
    • Jones, M. I.; Jenkins, James Stewart (ESO, 2014)
      Context. The recent discovery of three giant planets orbiting the extremely metal-poor stars HIP 11952 and HIP 13044 have challenged theoretical predictions of the core-accretion model. According to this, the metal content ...
    • Giovanelli, Ricardo; Dale, Daniel A.; Haynes, Martha P.; Hardy, Eduardo; Campusano, Luis E. (UNIV CHICAGO PRESS, 1999-11-01)
      Zehavi et al. have suggested that the Hubble flow within 70 h(-1) Mpc may be accelerated by the existence of a void centered on the Local Group. Its underdensity would be similar to 20%, which would result in a local Hubble ...

U.; Watson, Darach; Thöne, Christina C.; Sollerman, Jesper; Bloom, Joshua S.; Davis, Tamara M.; Hjorth, Jens; Jakobsson, Páll; Jørgensen, Uffe G.; Graham, John F.; Fruchter, Andrew S.; Bersier, David; Kewley, Lisa; Cassan, Arnaud; Castro Cerón, José María; Foley, Suzanne; Gorosabel, Javier; Hinse, Tobias C.; Horne, Keith D.; Jensen, Brian L.; Klose, Sylvio; Kocevski, Daniel; Marquette, Jean-Baptiste; Perley, Daniel; Ramírez Ruiz, Enrico; Stritzinger, Maximilian D.; Vreeswijk, Paul M.; Wijers, Ralph A. M.; Woller, Kristian G.; Xu, Dong; Zub, Marta (NATURE PUBLISHING GROUP, 2006-12-21)
      It is now accepted that long-duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star(1,2). The standard 'collapsar' model(3) predicts that a broad-lined and luminous type Ic core-collapse supernova ...
    • Rial, Ramón; Tahoces, Pablo G.; Hassan, Natalia; Cordero, M. L.; Liu, Zhen; Ruso, Juan M. (Elsevier Ltd, 2019)
      Bioceramic nanoparticles have many potential applications within the biomedical device industry. However, these applications demand a precise control of their sizes, shapes and morphology which play a main role in most ...
    • Canales Pérez, Félix Sebastián (Universidad de Chile, 2011)
      En Chile la minería es la principal industria, generando grandes recursos y está en constante crecimiento. En coordinación con este desarrollo, la seguridad tanto para equipos y personas debe mantener la normativa, que ...
    • Elmegreen, Bruce G.; Herrera, Cinthya; Rubio López, Mónica; Elmegreen, Debra Meloy; Sánchez Almeida, Jorge; Muñoz-Tuñón, Casiana; Olmo-García, Amanda (Iop Publishing LTD, 2018-06)
      A giant star-forming region in a metal-poor dwarf galaxy has been observed in optical lines with the 10 m Gran Telescopio Canarias (GTC) and in the emission line of CO(1-0) with the Northern Extended Millimeter Array (NOEMA) ...
    • Jara Schulz, Gladys; Ferré Díaz, Michel; Falcón Beas, Claudio; Clerc Gavilán, Marcel (Elsevier, 2020)
      Out of equilibrium systems are characterized by exhibiting the coexistence of domains with complex spatiotemporal dynamics. Here, we investigate experimentally the noise-induced domain wall propagation on a one-dimensional ...
    • Torres Ledesma, César Enrique (Universidad de Chile, 2013)
      Esta tesis consiste de cinco partes. En la primera parte se considera el problema de Dirichlet lineal y no lineal con una difusi\'on no local regional definido implicitamente por {\small \begin{equation}\label{Aeq03} ...
    • Fontoba Torres, Joaquín; Méléard, Sylvie (Springer, 2015)
      We introduce a stochastic individual model for the spatial behavior of an animal population of dispersive and competitive species, considering various kinds of biological effects, such as heterogeneity of environmental ...
    • Dymarz, Tullia; Navas, Andre S. (Indiana University Mathematics Journal, 2018)
      Given a lattice Gamma subset of SOL, we show there is a uniformly discrete coarsely dense subset D subset of Gamma that is not bi-Lipschitz equivalent to Gamma. We also prove similar results for lattices in certain higher ...
    • da Silva, I. D.; Moura, M. C.; Lins, I. D.; López Droguett, Enrique; Braga, E. (IEEE, 2017)
      A company performance strongly depends on its ability of delivering the right quantity of of a given product at the time customers require. Even though some demand forecasting techniques have been developed, they have ...
    • Carreras-Sureda, Amado; Jaña, Fabián; Urra, Hery; Durand, Sylvere; Mortenson, David E.; Sagredo, Alfredo; Bustos, Galdo; Hazari, Younis; Ramos-Fernández, Eva; Sassano, Maria L.; Pihán, Philippe; van Vliet, Alexander R.; González-Quiroz, Matías; Torres, Angie K.; Tapia- (Nature Publishing Group, 2019)
      Mitochondria-associated membranes (MAMs) are central microdomains that fine-tune bioenergetics by the local transfer of calcium from the endoplasmic reticulum to the mitochondrial matrix. Here, we report an unexpected ...
    • Adly, Samir; Le, Ba Khiet (Taylor & Francis, 2017)
      By using a regularization method, we study in this paper the global existence and uniqueness property of a new variant of non-convex sweeping processes involving maximal monotone operators. The system can be considered as ...
    • Marian, Max; Bartz, Marcel; Wartzack, Sandro; Rosenkranz, Andreas (MDPI, 2020)
      Apart from complex numerical models to predict the tribological behavior of elastohydrodynamically lubricated contacts, non-dimensional similarity groups and analytically solvable proximity equations can be used to estimate ...
    • Palma, Gonzalo A.; Scheihing Hitschfeld, Bruno; Sypsas, Spyros (IOP Publishing, 2020)
      Cosmic inflation may have led to non-Gaussian initial conditions that cannot be fully parametrised by 3- and/or 4-point functions. In this work, we discuss various strategies to search for primordial non-Gaussianity beyond ...
    • Hojman Guiñerman, Sergio; Asenjo, Felipe (Springer New York LLC, 2018)
      Recent interest on studying possible violations of the Equivalence Principle has led to the development of space satellite missions testing it for bodies moving on circular orbits around Earth. This experiment establishes ...
    • Martinez Alvarez, V.; Barrios-Vargas, J.; Foa Torres, L. (American Physical Society, 2018)
      Capital to topological insulators, the bulk-boundary correspondence ties a topological invariant computed from the bulk (extended) states with those at the boundary, which are hence robust to disorder. Here we put forward ...
    • Guzmán Jara, Marcelo Andrés (Universidad de Chile, 2018)
