Item Open Access A search for pulsed high-energy non-thermal emission from the nova-like variable system AE Aquarii(University of the Free State, 2015-05) Van Heerden, Hendrik Jacobus; Meintjes, P. J.English: AE Aquarii is an peculiar nova like variable system with emission observable in almost all wavelength regimes. The emission consists of both thermal and nonthermal components. The parameters and models for the non-thermal Synchrotron emission in the radio regime, as well as the optical and UV emission, have been extensively studied and presented since this enigmatic source was first studied in the 1930s. However, the emission processes and parameters towards the higher energies are still not clearly verified. The possibility of non-thermal pulsed emission in the VHE energies was mentioned in previous studies, as well as possible correlations between this pulsed emission and periods of enhanced optical activity. We searched for non-thermal high energy emission from AE Aquarii using archival data from Suzaku, Fermi and AGILE along with contemporaneous optical photometric data from Boyden Observatory and SAAO. Analysis of the parameters of optical ares resulted in signatures that was used to identify possible correlating features in the Fermi-LAT data. In addition, we found that given the presence of a thermal component in conjunction with a power-law towards higher energies in the Suzaku X-ray data, as well as a possible low-level pulse signal in the Fermi- LAT data at the first harmonic of the white dwarf spin period, the possibility of non-thermal high energy emission from AE Aquarii cannot be excluded. The possible low-level signal in the Fermi-LAT data was as a result of a novel peak distribution analysis technique. Finally, an updated spectral energy distribution for AE Aquarii was completed to serve as a reference for future studies.
