Gamma-Ray Absorption By The Cosmic Lyman Continuum From Star-forming Galaxies
Matthew A. Malkan, Sean T. Scully, Floyd W. Stecker
Motivated by the discovery of the ultra-strong emission line starburst galaxies (EELGs) known as "green pea galaxies", we consider here their contribution to the intergalactic flux…
An Empirical Determination of the Intergalactic Background Light from UV to FIR Wavelengths Using FIR Deep Galaxy Surveys and the Gamma-ray Opacity of the Universe
Floyd W. Stecker, Sean T. Scully, Matthew A. Malkan
We have previously calculated the intergalactic background light (IBL) as a function of redshift in the far ultraviolet to near infrared range, based purely on data from deep galax…
Searching for Traces of Planck-Scale Physics with High Energy Neutrinos
Floyd W. Stecker, Sean T. Scully, Stefano Liberati +1
High energy cosmic neutrino observations provide a sensitive test of Lorentz invariance violation, which may be a consequence of quantum gravity theories. We consider a class of no…
Propagation of Superluminal PeV IceCube Neutrinos: A High Energy Spectral Cutoff or New Constraints on Lorentz Invariance Violation
Floyd W. Stecker, Sean T. Scully
The IceCube observation of cosmic neutrinos with TeV, most of which are likely of extragalactic origin, allows one to severely constrain Lorentz invariance violation (LI…
An Empirical Determination of the Intergalactic Background Light Using NIR Deep Galaxy Survey Data out to 5 microns and the Gamma-ray Opacity of the Universe
Sean T. Scully, Matthew A. Malkan, Floyd W. Stecker
We extend our previous model-independent determination of the intergalactic background light (IBL), based purely on galaxy survey data, out to a wavelength of 5 microns. Our approa…
A Determination of the Intergalactic Redshift Dependent UV-Optical-NIR Photon Density Using Deep Galaxy Survey Data and the Gamma-ray Opacity of the Universe
Floyd W. Stecker, Matthew A. Malkan, Sean T. Scully
We calculate the intensity and photon spectrum of the intergalactic background light (IBL) as a function of redshift using an approach based on observational data obtained in many…
