    • A centimetre-wave excess over free–free emission in planetary nebulae 
      Casassus Montero, Simón; Nyman, L. A.; Dickinson, C.; Pearson, T. J. (WILEY-BLACKWELL, 2007-12-21)
      We report a centimetre-wave (cm-wave, 5-31 GHz) excess over free-free emission in planetary nebulae (PNe). Accurate 31- and 250-GHz measurements show that the 31-GHz flux densities in our sample are systematically higher ...
    • A characteristic martingale related to the counting process of records 
      Gouet Bañares, Raúl; López, F. Javier; Sanz, Gerardo (2007)
      Let (Xn) be a sequence of nonnegative, integrable, independent and identically distributed random variables, with common distribution function F. We consider the problem of finding all distribution functions F such that ...

(IOP Publishing, 2018-09)
      IC 166 is an intermediate-age open cluster (OC) (similar to 1 Gyr) that lies in the transition zone of the metallicity gradient in the outer disk. Its location, combined with our very limited knowledge of its salient ...
    • A clumpy and anisotropic galaxy halo at redshift 1 from gravitational-arc tomography 
      López Morales, Sebastián; Tejos, Nicolás; Ledoux, Cedric; Barrientos, Felipe L.; Sharon, Keren; Rigby, Jane R.; Gladders, Michael D.; Bayliss, Matthew B.; Pessa, Ismael (Nature Publishing Group, 2018)
      Every star-forming galaxy has a halo of metal-enriched gas that extends out to at least 100 kiloparsecs(1-3), as revealed by the absorption lines that this gas imprints on the spectra of background quasars(4). However, ...
