    • Combined constraints on deviations of dark energy from an ideal fluid from Euclid and Planck 
      Majerotto, Elisabetta; Sapone, Doménico; Schäfer, Björn Malte (Oxford University Press, 2016)
      Cosmological fluids are commonly assumed to be distributed in a spatially homogeneous way, while their internal properties are described by a perfect fluid. As such, they influence the Hubble expansion through their ...
    • A comparative study of Type II-P and II-L supernova rise times as exemplified by the case of LSQ13cuw 
      Gall, H.; Polshaw, J.; Kotak, R.; Jerkstrand, A.; Leibundgut, B.; Rabinowitz, D.; Sollerman, J.; Sullivan, M.; Smartt, S.; Anderson, J.; Benetti, S.; Baltay, C.; Feindt, U.; Fraser, M.; González Gaitán, Santiago; Inserra, C.; Maguire, K.; McKinnon, R.; Valenti, S.; Young, D. (EDP Sciences, 2015)
      We report on our findings based on the analysis of observations of the Type II-L supernova LSQ13cuw within the framework of currently accepted physical predictions of core-collapse supernova explosions. LSQ13cuw was ...
    • Euclid: The reduced shear approximation and magnification bias for Stage IV cosmic shear experiments? 
      Deshpande, A. C.; Kitching, T. D.; Cardone, V. F.; Taylor, P. L.; Casas, S.; Camera, S.; Carbone, C.; Kilbinger, M.; Pettorino, V.; Sakr, Z.; Sapone, Domenico; Tutusaus, I.; Auricchio, N.; Bodendorf, C.; Bonino, D.; Brescia, M.; Capobianco, V.; Carretero, J.; Castellano, M.; Cavuoti, S.; Cledassou, R.; Congedo, G.; Conversi, L.; Corcione, L.; Cropper, M.; Dubath, F.; Dusini, S.; Fabbian, G.; Franceschi, E.; Fumana, M.; Garilli, B; Grupp, F.; Hoekstra, H.; Hormuth, F.; Israel, H.; Jahnke, K.; Kermiche, S.; Kubik, B.; Kunz, M.; Lacasa, F.; Ligori, S.; Lilje, P. B.; Lloro, I.; Maiorano, E.; Marggraf, O.; Massey, R.; Mei, S.; Meneghetti, M.; Meylan, G.; Moscardini, L.; Padilla, C.; Paltani, S.; Pasian, F.; Pires, S.; Polenta, G.; Poncet, M.; Raison, F.; Rhodes, J.; Roncarelli, M.; Saglia, R.; Schneider, P.; Secroun, A.; Serrano, S.; Sirri, G.; Starck, J. L.; Sureau, F.; Taylor, A. N.; Tereno, I.; Toledo Moreo, R.; Valenziano, L.; Wang, Y.; Zoubian, J. (EDP Sciences, 2020)
      Context. Stage IV weak lensing experiments will offer more than an order of magnitude leap in precision. We must therefore ensure that our analyses remain accurate in this new era. Accordingly, previously ignored systematic ...
    • Gap formation and its consequence in the evolution of SMBHs binaries in galaxy mergers 
      Valle, L. del; Escala Astorquiza, Andrés (Wiley & Sons, 2015)
      Motivated by the theoretical and observational evidence that after a major merger of gas-rich galaxies a massive gaseous disk with a SMBH binary will be formed in the nuclear region of the remnant, we study the interaction ...
    • Optimality of the maximum likelihood estimator in astrometry 
      Espinosa, Sebastian; Silva, Jorge; Mendez, Rene; Lobos, Rodrigo; Orchard Concha, Marcos (EDP Sciences, 2018)
      Context. Astrometry relies on the precise measurement of positions and motions of celestial objects. Driven by the ever-increasing accuracy of astrometric measurements, it is important to critically assess the maximum ...
    • Relativistic Cyclotron Instability in Anisotropic Plasmas 
      López, Rodrigo A.; Moya Fuentes, Pablo; Navarro, Roberto; Araneda, Jaime; Muñoz Gálvez, Víctor; Viñas, Adolfo; Valdivia Hepp, Juan (IOP, 2016)
      A sufficiently large temperature anisotropy can sometimes drive various types of electromagnetic plasma micro-instabilities, which can play an important role in the dynamics of relativistic pair plasmas in space, astrophysics, ...
