Figure 2

Frequency dependence of the excess effective antenna temperature $\Delta T$ when pointing to the Sun and the Galactic center [28]. The top band is a model of the expected $\Delta T$, with a width equal to the systematic uncertainties. The lower two bands give contributions due to galactic and solar emissions, respectively. The antenna frequency response is folded into the model.Reuse & Permissions

Limits on various models for neutrino fluxes at EeV to ZeV energies. The limits are AMANDA cascades [29], RICE [30], the current work, GLUE [27], the FORTE satellite [20], and projected sensitivity for the full ANITA. Models shown are topological defects for two values of the $X$-particle mass [9], a TD model involving mirror matter [10], a range of models for GZK cosmogenic neutrinos [22, 24, 25], and several models for $Z$ bursts [6, 26]. In the $Z$-burst models plotted as points, the flux is a narrow spectral feature in energy, and the error bars shown indicate the range possible for the central energy and peak flux values.Reuse & Permissions
