High Energy Gamma-ray Absorption and Cascade Emission in Nearby Starburst Galaxies [PDF]
, 2010 High energy gamma-ray emission from two nearby bright starburst galaxies, M82 and NGC 253, have recently been detected by Fermi, H.E.S.S., and VERITAS. Since starburst galaxies have a high star formation rate and plenty of dust in the central starburst ...

Spectral and temporal signatures of ultrarelativistic protons in compact sources [PDF]
, 2005 We present calculations of the spectral and temporal radiative signatures expected from ultrarelativistic protons in compact sources. The coupling between the protons and the leptonic component is assumed to occur via Bethe-Heitler pair production.

Non-Null Weakened Mannheim curves
, 2012 In this study, non-null Frenet-Mannheim curves and non-null Weakened Mannheim curves are investigated in Minkowski 3-space. Some characterizations for this curves are obtained.

Alternative gravity rotation curves for the Little Things Survey
, 2017 Galactic rotation curves have proven to be the testing ground for dark matter bounds in spiral galaxies of all morphologies. Dwarf galaxies serve as an increasingly interesting case of rotation curve dynamics due to their typically rising rotation curve ...

Self-motions of pentapods with linear platform [PDF]
, 2015 We give a full classification of all pentapods with linear platform possessing a self-motion beside the trivial rotation about the platform. Recent research necessitates a contemporary and accurate re-examination of old results on this topic given by ...

Generalized Timelike Mannheim Curves in Minkowski Space‐Time E14 [PDF]
Mathematical Problems in Engineering, 2011 We give the definition of generalized timelike Mannheim curve in Minkowski space‐time . The necessary and sufficient conditions for the generalized timelike Mannheim curve are obtained. We show some characterizations of generalized Mannheim curve.

High-Energy Neutrinos from Photomeson Processes in Blazars [PDF]
, 2001 An important radiation field for photomeson neutrino production in blazars is shown to be the radiation field external to the jet. Assuming that protons are accelerated with the same power as electrons and injected with a -2 number spectrum, we predict ...

Generalized Mannheim quaternionic curves in Euclidean 4-space
Applied Mathematical Sciences, 2013 In this paper, we define a generalized Mannheim quaternionic curve in the four-dimensional Euclidean space R 4 and investigate the properties of it.
