  3. Astrophysics. Multiple images of a highly magnified supernova formed by an early-type cluster galaxy lens.

    Science 347(6226):1123 (2015) PMID 25745167

    In 1964, Refsdal hypothesized that a supernova whose light traversed multiple paths around a strong gravitational lens could be used to measure the rate of cosmic expansion. We report the discovery of such a system. In Hubble Space Telescope imaging, we have found four images of a single superno...
  4. A dust-parallax distance of 19 megaparsecs to the supermassive black hole in NGC 4151.

    Nature 515(7528):528 (2014) PMID 25428499

    The active galaxy NGC 4151 has a crucial role as one of only two active galactic nuclei for which black hole mass measurements based on emission line reverberation mapping can be calibrated against other dynamical techniques. Unfortunately, effective calibration requires accurate knowledge of th...

  7. Rapid formation of large dust grains in the luminous supernova 2010jl.

    Nature 511(7509):326 (2014) PMID 25030169

    The origin of dust in galaxies is still a mystery. The majority of the refractory elements are produced in supernova explosions, but it is unclear how and where dust grains condense and grow, and how they avoid destruction in the harsh environments of star-forming galaxies. The recent detection ...

  9. The supernova-gamma-ray burst-jet connection.

    Philosophical Transactions of the Royal Society... 371(1992):20120275 (2013) PMID 23630379

    The observed association between supernovae and gamma-ray bursts represents a cornerstone in our understanding of the nature of gamma-ray bursts. The collapsar model provides a theoretical framework for this connection. A key element is the launch of a bipolar jet (seen as a gamma-ray burst). Th...

  11. Impact of a European directive on ship emissions on air quality in Mediterranean harbours

    Atmospheric Environment 61:661 (2012)

    Ships have been found to be major sources of air pollution in harbours. However, from January 1, 2010, a European Union directive requires that all ships at berth or anchorage in European harbours use fuels with a sulphur content of less than 0.1% by weight while previously, outside of...

  16. Gravitational redshift of galaxies in clusters as predicted by general relativity.

    Nature 477(7366):567 (2011) PMID 21956329

    The theoretical framework of cosmology is mainly defined by gravity, of which general relativity is the current model. Recent tests of general relativity within the Lambda Cold Dark Matter (ΛCDM) model have found a concordance between predictions and the observations of the growth rate and clust...

  18. Simulated dark-matter halos as a test of nonextensive statistical mechanics.

    Physical Review E 77(2 Pt 1):022106 (2008) PMID 18352070

    In the framework of nonextensive statistical mechanics, the equilibrium structures of astrophysical self-gravitating systems are stellar polytropes, parametrized by the polytropic index n . By careful comparison to the structures of simulated dark-matter halos we find that the density profiles, ...

  20. No supernovae associated with two long-duration gamma-ray bursts.

    Nature 444(7122):1047 (2006) PMID 17183316

    It is now accepted that long-duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. The standard 'collapsar' model predicts that a broad-lined and luminous type Ic core-collapse supernova accompanies every long-duration GRB. This association has been confirmed in ob...
