TL;DR
This study used MAGIC telescopes alongside multi-wavelength observations to search for TeV gamma-ray emission from AE Aqr during various states, aiming to confirm or refute previous high-energy emission claims.
Contribution
First coordinated multi-wavelength campaign with MAGIC to search for TeV emission from AE Aqr during high states and at the white dwarf's rotation period.
Findings
No steady TeV emission detected.
No variable TeV emission coincident with optical/X-ray peaks.
No periodic TeV emission at the white dwarf's rotation period.
Abstract
We report on observations of the nova-like cataclysmic variable AE Aqr performed by MAGIC. The observations were part of a quasi-simultaneous multi-wavelength campaign carried out between 2012 May and June covering the optical, UV, X-ray and gamma-ray ranges. MAGIC conducted the campaign and observed the source during 12 hours. The other instruments involved were KVA, Skinakas, and Vidojevica in the optic and Swift in the X-ray. We also used optical data from the AAVSO. The goals were to: monitor the variability of the source at different wavelengths, perform gamma-ray studies coincident with the highest states of the source at the other wavelengths, and confirm or rule out previous claims of detection of very-high-energy emission from this object. We report on a search for steady TeV emission during the whole observation, for variable TeV emission coincident with the highest optical…
