High sensitivity low frequency radio observations of cD galaxies
S. Giacintucci, T. Venturi, S. Bardelli +3
We present the GMRT 235 MHz images of three radio galaxies and 610 MHz images of two sources belonging to a complete sample of cD galaxies in rich and poor galaxy clusters. The ana…
Optical Spectroscopy of the Large Kuiper Belt Objects 136472 (2005 FY9) and 136108 (2003 EL61)
S. C. Tegler, W. Grundy, W. Romanishin +3
We present high signal precision optical reflectance spectra of the large Kuiper belt objects 2005 FY9 and 2003 EL61. The spectrum of 2005 FY9 exhibits strong CH4-ice bands. A comp…
Observation of VHE Gamma Radiation from HESS J1834-087/W41 with the MAGIC Telescope
J. Albert et al.
Recently, the HESS array has reported the detection of gamma-ray emission above a few hundred GeV from eight new sources located close to the Galactic Plane. The source HESS J1834-…
Early-Time Photometry and Spectroscopy of the Fast Evolving SN 2006AJ Associated with GRB 060218
M. Modjaz, K. Z. Stanek, P. M. Garnavich +10
We present early photometric and spectroscopic data on the afterglow of GRB 060218 and report the evolution of the underlying supernova 2006aj. Our data span a time-range of 4 days…
