• The Absence of Radio Emission from the Globular Cluster G1 

      Miller-Jones, J. C. A.; Wrobel, J. M.; Sivakoff, G. R.; Heinke, C. O.; Miller, R. E.; Plotkin, R. M.; Di Stefano, R.; Greene, J. E.; Ho, L. C.; Joseph, T. D.; Kong, A. K. H.; Maccarone, T. J. (2012-08)
      The detections of both X-ray and radio emission from the cluster G1 in M31 have provided strong support for existing dynamical evidence for an intermediate-mass black hole (IMBH) of mass (1.8 +/- 0.5) x 10(4) M-circle dot ...
    • The First Two Transient Supersoft X-Ray Sources In M 31 Globular Clusters And The Connection To Classical Novae 

      Henze, M.; Pietsch, W.; Haberl, F.; Sala, G.; Quimby, R.; Hernanz, M.; Della Valle, M.; Milne, P.; Williams, G. G.; Burwitz, V.; Greiner, J.; Stiele, H.; Hartmann, D. H.; Kong, A. K. H.; Hornoch, K. (2009-06)
      Context. Classical novae (CNe) have been found to represent the major class of supersoft X-ray sources (SSSs) in our neighbour galaxy M 31. Aims. We determine the properties and evolution of the two first SSSs ever discovered ...
    • The Unusually Luminous Extragalactic Nova SN 2010U 

      Czekala, Ian; Berger, E.; Chornock, Ryan; Pastorello, A.; Marion, G. H.; Margutti, R.; Botticella, M. T.; Challis, Peter; Ergon, M.; Smartt, S.; Sollerman, Jesper; Vinko, Jozsef; Wheeler, J. Craig (2013-03)
      We present observations of the unusual optical transient SN 2010U, including spectra taken 1.03 days to 15.3 days after maximum light that identify it as a fast and luminous Fe II type nova. Our multi-band light curve ...
