    • 23 GHz VLBI Observations of SN 2008ax 

      Marti-Vidal, I.; Alberdi, A.; Ros, E.; Shapiro, Irwin Ira; Beswick, R.J.; Pedlar, A.; Immler, S.; Panagia, N.; Van Dyk, S.; Marcaide, J. M.; Guirado, J. C.; Perrez-Torres, M. A.; Muxlow, T. W. B.; Argo, M. K.; Stockdale, C. J.; Sramek, R. A.; Weiler, K. W. (EDP Sciences, 2009)
      We report on phase-referenced 23 GHz Very-Long-Baseline-Interferometry (VLBI) observations of the type IIb supernova SN 2008ax, made with the Very Long Baseline Array (VLBA) on 2 April 2008 (33 days after explosion). These ...

S. (IOP Publishing, 2010)
      Centaurus (Cen) A represents one of the best candidates for an isolated, compact, highly polarized source that is bright at typical cosmic microwave background (CMB) experiment frequencies. We present measurements of the ...

    • The Collimated Jet Source in IRAS 16547-4247: Time Variation, Possible Precession, and Upper Limits to the Proper Motions along the Jet Axis 

      Rodríguez, Luis F.; Moran, James M.; Franco-Hernández, Ramiro; Garay, Guido; Brooks, Kate J.; Mardones, Diego (American Astronomical Society, 2008)
      The triple radio source detected in association with the luminous infrared source IRAS 16547-4247 has previously been studied with high angular resolution and high sensitivity with the Very Large Array at 3.6 cm wavelength. ...

    • A Decade of SN 1993J: Discovery of Radio Wavelength Effects in the Expansion Rate 

      Marcaide, J.M.; Marti-Vidal, I.; Alberdi, A.; Perrez-Torres, M.A.; Ros, E.; Diamond, P.J.; Guirado, J.C.; Lara, L.; Shapiro, Irwin Ira; Stockdale, C.J.; Weiler, K.W.; Mantovani, F.; Preston, R.A.; Schilizzi, R.T.; Sramek, R.A.; Trigilio, C.; Van Dyk, S.D.; Whitney, A.R. (EDP Sciences, 2009)
      We studied the growth of the shell-like radio structure of supernova SN 1993J in M 81 from September 1993 to October 2003 with very-long-baseline interferometry (VLBI) observations at the wavelengths of 3.6, 6, and 18 cm. ...

(IOP Publishing, 2002)
      We discuss the optical and radio properties of ~30,000 FIRST (radio, 20 cm, sensitive to 1 mJy) sources positionally associated within 1farcs5 with a Sloan Digital Sky Survey (SDSS) (optical, sensitive to r* ~ 22.2) source ...
