Abstract

The Radio Neutrino Observatory – Greenland (RNO-G) is an in-ice
neutrino detector currently under construction. The detector is designed to make the first measurement of neutrinos beyond energies of $\sim$10 PeV.
Each of the planned 35 stations of the detector includes three
log-periodic dipole array antennas (LPDA) pointing towards the sky. The stations cover an area of $\sim$ 50 km$^2$ and enable RNO-G to measure the radio emission of cosmic-ray induced air-showers, thus making it a cosmic-ray detector as well. As other experiments have shown, such radio emission can be used to make precision cosmic-ray measurements. Additionally,
the location of the experiment at Summit Station, at a height of $\sim$3000 m, enables RNO-G to study the phenomena of shower cores hitting the air/ice boundary and further developing in the ice itself. Moreover, RNO-G is also able to study high energetic muons, created in cosmic-ray induced air-showers, which penetrate into the ice from above.
In this contribution, we will give an overview of the cosmic-ray analysis of RNO-G and report the current status. This includes outlining the method used for identifying the air-shower signals using signal templates, showing the
first cosmic-ray candidate events and discussing systematic uncertainties.
