Very high energy gamma ray observations of southern hemisphere blazars [PDF]

, 1997
This thesis is concerned with very high energy γ-ray observations of blazars observable from the southern hemisphere. The data presented were obtained using the recently deployed University of Durham Mark 6 high sensitivity Čerenkov telescope. Chapters 1

Cosmic Rays from the Nucleus of M87

, 2003
© 2003 by Universal Academy PressThe unresolved nuclear region of M87 emits strong non-thermal emission from radio to X-rays, and this has been interpreted as jet emission from a misaligned BL Lac Object in the context of the Synchrotron Proton Blazar ...

Neural networks for separation of cosmic gamma rays and hadronic cosmic rays in air shower observation with a large area surface detector array

Machine Learning: Science and Technology
The Tibet AS γ experiment has been observing cosmic gamma rays and cosmic rays in the energy range from teraelectron volts to several tens of petaelectron volts with a surface detector array since 1990.

On the relationship of cosmic ray flux and precipitation [PDF]

, 2001
This paper evaluates whether there is empirical evidence to support the hypothesis that solar variability is linked to the Earth's climate through the modulation of atmospheric precipitation processes.

Long-term changes in cosmic rays derived from cosmogenic radionuclides

, 2008
Direct continuous records of cosmic rays are restricted to the past 50 years, the era of neutron monitors. Ionization chambers provide an additional 20 years of data.

Nuclear cosmic rays from supernova remnants

, 2003
The nonlinear kinetic model of cosmic ray (CR) acceleration in supernova remnants (SNRs) is used to describe the properties of the young remnants of SN 1006, Tycho's supernova, and Cassiop eia A in the Galaxy. The calculated expansion law and the radio-,
