Emission line oscillations in the dwarf nova V2051 Ophiuchi

D. Steeghs, K. O'Brien, K. Horne +2

We have detected coherent oscillations, at multiple frequencies, in the line and continuum emission of the eclipsing dwarf nova V2051 Ophiuchi using the 10m Keck II telescope. Our…

Balmer-Dominated Spectra of Nonradiative Shocks in the Cygnus Loop, RCW 86 and Tycho Supernova Remnants

Parviz Ghavamian, John Raymond, R. Chris Smith +1

We present an observational and theoretical study of the optical emission from nonradiative shocks in three supernova remnants: the Cygnus Loop, RCW 86 and Tycho. The spectra of th…

Complex Phase Lag Behaviors of the 0.5 - 10 Hz QPOs in GRS 1915+105

D. Lin, I. A. Smith, E. P. Liang +1

Through studying the hard lags between the soft (3.3 - 5.8 keV) and hard (13.0 - 41.0 keV) photons of the 0.5 - 10 Hz QPOs in GRS 1915+105, we have classified them into three types…

Monte-Carlo simulations of thermal/nonthermal radiation from a neutron-star magnetospheric accretion shell

M. Boettcher, E. P. Liang

We discuss the space-and-time-dependent Monte Carlo code we have developed to simulate the relativistic radiation output from compact astrophysical objects, coupled to a Fokker-Pla…

The Starburst-Interstellar Medium Interaction of NGC 1569 I. Location and Nature of He II Sources Using Hubble Space Telescope WFPC2 Imagery

Brent A. Buckalew, Reginald J. Dufour, Patrick L. Shopbell +1

We present the detection of He II sources in the Im galaxy NGC 1569 from HST WFPC2 imagery. Out of the fifteen detections, seven were Wolf-Rayet stars, five were stellar clusters w…

X-ray spectral features from GRBs: Predictions of progenitor models

M. Boettcher, C. L. Fryer

We investigate the potentially observable prompt or delayed X-ray spectral features from the currently popular gamma-ray burst (GRB) models. During the evolution of many GRB progen…

Flash-Heating of Circumstellar Clouds by Gamma Ray Bursts

Charles D. Dermer, Markus Boettcher

The blast-wave model for gamma-ray bursts (GRBs) has been called into question by observations of spectra from GRBs that are harder than can be produced through optically thin sync…

Multiwavelength observations of Mkn 501 during the 1997 high state

D. Petry, M. Boettcher, V. Connaughton +10

During the observation period 1997, the nearby Blazar Mkn 501 showed extremely strong emission and high variability. We examine multiwavelength aspects of this event using radio, o…
