      We report on the serendipitous discovery of an unprecedented interaction between the radio lobe of a radio galaxy and a spiral galaxy. The discovery was made thanks to LOFAR observations at 144 MHz of the galaxy cluster ...
    • On the enhancement of speaker identification accuracy using weighted bilateral scoring 

      Malegaonkar, A.; Ariyaeeinia, A.; Sivakumaran, P.; Fortuna, J. (2008-10-16)
      This paper presents investigations into an effective bilateral scoring method in open-set speaker identification. The approach is based on the fact that two different speakers usually are not reciprocal. A difficulty in ...

      Rotational receptances can perform an important role when predicting the dynamic behaviour both in theoretical and experimental models, especially when a modification includes a rotational inertia or a rotational stiffness. ...

    • On the Evolved Nature of CK Vul 

      Hajduk, M.; Zijlstra, A.A.; van Hoof, P.A.M.; Lopez, J.A.; Drew, J.E.; Evans, A.; Eyres, S.P.S.; Gesicki, K.; Greimel, R.; Kerber, F.; Kimeswenger, S.; Richer, M.G. (Astronomical Society of the Pacific, 2008)
      CK Vul was classified as the oldest observed nova. Recent studies have proven however, that CK Vul cannot be unambiguously classified as any known kind of eruptive variable. We present the optical and radio observations ...
    • On the Formation of Lines in Quantum Phase Space 

      Steuernagel, Ole; Yang, Popo; Lee, Ray-Kuang (2023-01-24)
      We theoretically study the formation of lines in phase space using Wigner’s distribution W. In trapped quantum systems such lines form generically, crisscrossing phase space and they can have astonishing extent, reaching ...
    • On the formation of massive galaxies : A simultaneous study of number density, size and intrinsic colour evolution in GOODS 

      Ferreras, I.; Lisker, T.; Pasquali, A.; Khochfar, S.; Kaviraj, S. (2009-07-01)
      The evolution of number density, size and intrinsic colour is determined for a volume-limited sample of visually classified early-type galaxies selected from the Hubble Space Telescope/Advanced Camera for Surveys images ...
    • On the fragility of nuclear stellar discs against galaxy mergers: surviving photometric and kinematic signatures of nuclear discs 

      Sarzi, M.; Ledo, H.~R.; Dotti, M. (2015-10-11)
      Nuclear stellar discs (NSDs) can help to constrain the assembly history of their host galaxies, as long as we can assume them to be fragile structures that are disrupted during merger events. In this work we investigate ...
    • On the frequency of Jupiter analogs 

      Wittenmyer, R.; Tinney, C.G.; O'Toole, S.; Jones, H.R.A.; Butler, R.P.; Carter, B.D.; Bailey, J. (2011)
      The Anglo-Australian Planet Search has now accumulated 12 years of radial-velocity data with long-term instrumental precision better than 3 m s-1. In this paper, we expand on earlier simulation work, to probe the frequency ...
    • On the geometry of the orthogonal momentum amplituhedron 

      Łukowski, Tomasz; Moerman, Robert; Stalknecht, Jonah (2022-12-01)

    • On the globular cluster formation history of NGC 5128 

      Kaviraj, S.; Ferreras, I.; Yoon, S.-J.; Yi, S.K. (2005-09-01)

    • On the incidence of episodic accretion in Class I YSOs from VVV 

      Peña, Carlos Contreras; Lucas, Philip W.; Guo, Zhen; Smith, Leigh (2024-02-01)
      Episodic accretion is one of the competing models to explain the observed luminosity spread in young stellar clusters. These short-lived high accretion events could also have a strong impact on planet formation. Observations ...
    • On the institutional foundations of law : The insufficiency of custom and private ordering 

      Hodgson, G. (2009-01-01)
      Some theorists propose that systems of law largely arise spontaneously, as an extension of customary rules. At most, the role of the state is to endorse customary laws and add some minimal general rules. Some see no essential ...
