    Very High Energy Observations of Gamma-Ray Burst Locations with the Whipple Telescope 

    Lang, Mark; Gillanders, Gary; Horan, D.; Atkins, R. W.; Badran, H. M.; Blaylock, G.; Bradbury, S. M.; Buckley, J. H.; Byrum, K. L.; Celik, O.; Chow, Y. C. K.; Cogan, P.; Cui, W.; Daniel, M. K.; Perez, I. de la Calle; Dowdall, C.; Falcone, A. D.; Fegan, D. J.; Fegan, S. J.; Finley, J. P.; Fortin, P.; Fortson, L. F.; Gillanders, G. H.; Grube, J.; Gutierrez, K. J.; Hall, J.; Hanna, D.; Holder, J.; Hughes, S. B.; Humensky, T. B.; Kenny, G. E.; Kertzman, M.; Kieda, D. B.; Kildea, J.; Krawczynski, H.; Krennrich, F.; Lang, M. J.; LeBohec, S.; Maier, G.; Moriarty, P.; Nagai, T.; Ong, R. A.; Perkins, J. S.; Petry, D.; Quinn, J.; Quinn, M.; Ragan, K.; Reynolds, P. T.; Rose, H. J.; Schroedter, M.; Sembroski, G. H.; Steele, D.; Swordy, S. P.; Toner, J. A.; Valcarcel, L.; Vassiliev, V. V.; Wagner, R. G.; Wakely, S. P.; Weekes, T. C.; White, R. J.; Williams, D. A. (2007)
    Gamma-ray burst (GRB) observations at very high energies (VHE, E > 100 GeV) can impose tight constraints on some GRB emission models. Many GRB afterglow models predict a VHE component similar to that seen in blazars and ...

    Deep optical observations of the interaction of the SS 433 microquasar jet with the W 50 radio continuum shell 

    Redman, Matt P. (2007)
    Four mosaics of deep, continuum-subtracted, CCD images have been obtained over the extensive galactic radio continuum shell, W 50, which surrounds the remarkable stellar system SS 433. Two of these mosaics in the Halpha+[N ...

    VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula) 

    Redman, Matt P. (2007)
    Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding the physics involved in knots ...

    CO abundances in a protostellar cloud: freeze-out and desorption in the envelope and outflow of L483 

    Redman, Matt P. (2007)
    CO isotopes are able to probe the different components in protostellar clouds. These components, core, envelope and outflow have distinct physical conditions and sometimes more than one component contributes to the observed ...

    Rotational Modulation of M/L Dwarfs due to Magnetic Spots 

    Butler, Ray (2007)
    We find periodic I-band variability in two ultracool dwarfs, TVLM 513-46546 and 2MASS J00361617+1821104, on either side of the M/L dwarf boundary. Both of these targets are short-period radio transients, with the detected ...

    A search for CO+ in planetary nebulae 

    Redman, Matt P. (2007)
    We have carried out a systematic search for the molecular ion CO+ in a sample of 8 protoplanetary and planetary nebulae in order to determine the origin of the unexpectedly strong HCO+ emission previously detected in these ...

    Kinematics of the Broad Line Region in M81 

    Shearer, Andrew (2007)
    A new model is presented which explains the origin of the broad emission lines observed in the LINER/Seyfert nucleus of M81 in terms of a steady state spherically symmetric inflow, amounting to 1 x 10^-5 Msun/yr, which is ...

    Multiwavelength Observations of Markarian 421 in March 2001: an Unprecedented View on the X-ray/TeV Correlated Variability 

    Lang, Mark (2007)
    (Abridged) We present a detailed analysis of week-long simultaneous observations of the blazar Mrk421 at 2-60 keV X-rays (RXTE) and TeV gamma-rays (Whipple and HEGRA) in 2001. The unprecedented quality of this dataset ...

    Pulse variation of the optical emission of Crab pulsar 

    Shearer, Andrew (2007)
    The stability of the optical pulse of the Crab pulsar is analyzed based on the 1 $\mu$s resolution observations with the Russian 6-meter and William Hershel telescopes equipped with different photon-counting detectors. The ...
