    • The stellar initial mass function in the galactic center 

      Figer, Donald (Springer: ASSL (Astrophysics and Space Science Library), 2004-09)
      Massive stars define the upper limits of the star formation process, dominate the energetics of their local environs, and significantly affect the chemical evolution of galaxies. Their role in starburst galaxies and the ...

    • An upper limit to the masses of stars 

      Figer, Donald (Nature Publishing Group: Nature, 2005-03-10)
      There is no accepted upper mass limit for stars. Such a basic quantity escapes both theory, because of incomplete understanding of star formation, and observation, because of incompleteness in surveying the Galaxy. The ...

    • The nature of the optical: Radio correlations for powerful radio galaxies 

      Tadhunter, Clive; Morganti, Raffaella; Robinson, Andrew; Dickson, Robert; Villar-Martin, Montse; Fosbury, Robert (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 1998-08)
      The nature of the optical–radio correlations for powerful radio galaxies is investigated using spectroscopic observations of a complete sample of southern 2Jy radio sources. In line with previous work, we find that significant ...

    • Gas dynamics in the barred Seyfert galaxy NGC4151 - II. High resolution HI study 

      Mundell, Carole; Pedlar, Alan; Shone, David; Robinson, Andrew (Blackwell Publishing: Monthly Notices of the Royal Astronomical Society, 1999-04)
      We present sensitive, high angular resolution (6′′ × 5′′) λ21-cm observations of the neutral hydrogen in the nearby barred Seyfert galaxy, NGC4151. These HI observations, obtained using the VLA in B-configuration, are the ...

    • Systolic and hyper-systolic algorithms for the gravitational N-body problem, with an application to Brownian motion 

      Dorband, Ernst; Hemsendorf, Marc; Merritt, David (Elsevier Science: Academic Press, 2003-03-01)
      A systolic algorithm rhythmically computes and passes data through a network of processors. We investigate the performance of systolic algorithms for implementing the gravitational N-body problem on distributed-memory ...

    • Tracing black hole mergers through radio lobe morphology 

      Merritt, David; Ekers, Ronald (American Association for the Advancement of Science: Science, 2002-08-23)
      Binary supermassive black holes are produced by galactic mergers as the black holes from the two galaxies fall to the center of the merged system and form a bound pair. The two black holes will eventually coalesce in an ...
