Long-term Spectra of the Blazars Mrk 421 and Mrk 501 at TeV Energies Seen by HAWC

The High Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory surveys the very high energy sky in 300 GeV to $>100$ TeV range. HAWC has detected two blazars above $11\sigma$, Markarian 421 (Mrk 421) and 501 501). observations are comprised of data taken period between June 2015 July 2018, resulting a $\sim 1038$ days exposure. In this work we report time-averaged spectral analysis for both sources 0.5 TeV. Taking into account flux attenuation due extragalactic background light (EBL), intrinsic spectrum Mrk is described by power law with an exponential cut-off index $\alpha=2.26\pm(0.12)_{stat}(_{-0.2}^{+0.17})_{sys}$ $E_c=5.1\pm(1.6)_{stat}(_{-2.5}^{+1.4})_{sys}$ TeV, while better simple $\alpha=2.61\pm(0.11)_{stat}(_{-0.07}^{+0.01})_{sys}$. maximum energies at which signals 9 12 respectively. This makes these some highest detections date spectra averaged over years-long timescales. Since observation gamma radiation from provides information about physical processes that take place their relativistic jets, it important study broad-band distribution (SED) objects. To purpose, contemporaneous gamma-ray band X-ray range, literature radio UV were used build SEDs modeled within synchrotron self-Compton leptonic scenario.
