Lorentz Invariance Violation and the Observed Spectrum of Ultrahigh Energy Cosmic Rays
S. T. Scully, F. W. Stecker
There has been much interest in possible violations of Lorentz invariance, particularly motivated by quantum gravity theories. It has been suggested that a small amount of Lorentz…
The dense ring in the Coalsack: the merging of two subsonic flows
J. M. Rathborne, C. J. Lada, W. Walsh +2
A recent high angular resolution extinction map toward the most opaque molecular globule, Globule 2, in the Coalsack Nebula revealed that it contains a strong central ring of dust…
Is the Universe More Transparent to Gamma Rays Than Previously Thought?
Floyd W. Stecker, Sean T. Scully
The MAGIC collaboration has recently reported the detection of the strong gamma-ray blazar 3C279 during a 1-2 day flare. They have used their spectral observations to draw conclusi…
The Spectrum of 1ES0229 + 200 and the Cosmic Infrared Background
F. W. Stecker, and S. T. Scully
We examine the effect of gamma-ray absorption by the extragalactic infrared radiation on intrinsic spectra predicted for 1ES0229+200 and compare our results with the observational…
An Unbiased Survey of 500 Nearby Stars for Debris Disks: A JCMT Legacy Program
B. C. Matthews, J. S. Greaves, W. S. Holland +28
We present the scientific motivation and observing plan for an upcoming detection survey for debris disks using the James Clerk Maxwell Telescope. The SCUBA-2 Unbiased Nearby Stars…
The James Clerk Maxwell Telescope Legacy Survey of Nearby Star-forming Regions in the Gould Belt
D. Ward-Thompson, J. Di Francesco, J. Hatchell +59
This paper describes a James Clerk Maxwell Telescope (JCMT) legacy survey that has been awarded roughly 500 hrs of observing time to be carried out from 2007 to 2009. In this surve…
Chemical chronology of the Southern Coalsack
S. D. Rodgers, S. B. Charnley, R. G. Smith +1
We demonstrate how the observed H2O ice column densities toward three dense globules in the Southern Coalsack could be used to constrain the ages of these sources. We derive ages o…
Corrected Table for the Parametric Coefficients for the Optical Depth of the Universe to Gamma-rays at Various Redshifts
F. W. Stecker, M. A. Malkan, S. T. Scully
Table 1 in our paper, ApJ 648, 774 (2006) entitled "Intergalactic Photon Spectra from the Far IR to the UV Lyman Limit for 0 < z < 6 and the Optical Depth of the Universe to High E…
A Simple Analytic Treatment of the Intergalactic Absorption Effect in Blazar Gamma-ray Spectra
F. W. Stecker, S. T. Scully
We derive a new and user friendly simple analytic approximation for determining the effect of intergalactic absorption in the energy range 0.2-2 TeV and the redshift range 0.05-0.4…
Intergalactic Photon Spectra from the Far IR to the UV Lyman Limit for and the Optical Depth of the Universe to High Energy Gamma-Rays
F. W. Stecker, M. A. Malkan, S. T. Scully
We calculate the intergalactic photon density as a function of both energy and redshift for 0 < z < 6 for photon energies from .003 eV to the Lyman limit cutoff at 13.6 eV in a Lam…
Lorentz Invariance Violation and the Spectrum and Source Power of Ultrahigh Energy Cosmic Rays
F. W. Stecker, S. T. Scully
Owing to their isotropy, it is generally believed that ultrahigh energy cosmic rays (UHECRs) are extragalactic in origin. It is then expected that interactions of these cosmic rays…
Neutrino astronomy with the MACRO detector
M. Ambrosio
High energy gamma ray astronomy is now a well established field and several sources have been discovered in the region from a few GeV up to several TeV. If sources involving hadron…
