Long-Lag, Wide-Pulse Gamma-Ray Bursts
Currently, the best available probe of the early phase of gamma-ray burst (GRB) jet attributes is the prompt gamma-ray emission, in which several intrinsic and extrinsic variables determine GRB pulse
Fermi gamma-ray imaging of a radio galaxy.
These measurements provide gamma-ray constraints on the magnetic field and particle energy content in radio galaxy lobes, as well as a promising method to probe the cosmic relic photon fields.
Exact vacuum solution to conformal Weyl gravity and galactic rotation curves
The complete, exact exterior solution for a static, spherically symmetric source in locally conformal invariant Weyl gravity is presented. The solution includes the familiar exterior Schwarzschild
Thermal Instability and Photoionized X-Ray Reflection in Accretion Disks
The self-consistent density determination makes evident the presence of a thermal ionization instability well known in the context of quasar emission line studies, and proposes that future X-ray reflection calculations should always utilize hydrostatic balance in order to provide a reliable interpretation ofX-ray spectra of active galactic nuclei and galactic black hole candidates.
Science with the Cherenkov Telescope Array
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA is extremely broad:
Decelerating Flows in TeV Blazars: A Resolution to the BL Lac -- FR I Unification Problem
TeV emission from BL Lacertae (BL) objects i s commonly modeled as Synchrotron-Self Compton (SSC) radiation from relativistically moving homogeneous plasma blobs. In the context of these models, the
A Method for Localizing Energy Dissipation in Blazars Using Fermi Variability
The distance of a Fermi-detected blazar γ-ray emission site from a supermassive black hole is a matter of active debate. Here we present a method for testing if the GeV emission of powerful blazars
Exact Expressions for the Critical Mach Numbers in the Two-Fluid Model of Cosmic-Ray-modified Shocks
The acceleration of relativistic particles due to repeated scattering across a shock wave remains the most attractive model for the production of energetic cosmic rays. This process has been analyzed
Multiwavelength observations of short-timescale variability in NGC 4151 .4. Analysis of multiwavelength continuum variability
For pt.III see ibid., vol.470, no.1, p.349-63 (1996). Combines data from the three preceding papers in order to analyze the multi wave-band variability and spectral energy distribution of the Seyfert
Timing Noise Properties of GRO J0422+32
OSSE observed the transient black hole candidate GRO J0422+32 (XN Per 92) between 1992 Aug 11 and 1992 Sep 17. High time resolution data were obtained in several energy bands over the 35-600 keV
