Abstract

GRAND is designed to detect ultra-high-energy cosmic particles -- specially neutrinos, cosmic rays and gamma rays using radio antennas. With $\sim$20 mountainous sites around the world it will cover a total area of 200,000 km$^{2}$. The planned sensitivity of 10$^{-10}$ GeV cm$^{-2}$ s$^{-1}$ sr$^{-1}$ above $5\times10^{17}$ eV will likely ensure the detection of cosmogenic neutrinos predicted by most common scenarios enabling neutrino astronomy. Furthermore, PeV--EeV neutrinos can test particle interactions at energies above those achieved in accelerators. The pathfinder stage GRANDProto300 is planned to start taking data in 2021. We present the current overall status of the project with emphasis on the neutrino physics.

Author comments upon resubmission

I would like to thank the referee for the feedback, suggestions and comments I received.
Alongside the changes requested regarding grammar, style and citations, in section 2, I made the increase in the exposure clearer mentioning it is to be compared with the exposure from the Pierre Auger Observatory. I also added a sentence on section 4.3 addressing the muon discrepancy mentioned earlier on the text.

List of changes

- Section 1, paragraph 2, Ref [2]: Included a citation to https://arxiv.org/abs/1903.07713
- Section 2, paragraph 1: I made the increase in the exposure clearer mentioning it is to be compared with the exposure from the Pierre Auger Observatory
- Section 2, paragraph 3: "involved on the" -> "involved in the"
- Section 2, paragraph 4: Made it clear that this is the sensitivity for gamma rays.
- Section 3, paragraph 3: "in the atmosphere and also" removed "and"
- Section 4.1, paragraph 1: Removed "(EBL)"
- Section 4.1, last paragraphs: Merged the last three paragraphs.
- Section 4.2, last bullet: Removed extra space at "(CRB) ." and "to" in "(up to to 10Mpc)".
- Section 4.3: I added a sentence addressing the muon discrepancy mentioned earlier on the text.
- Section 4.4, paragraph 2: Put a comma between "timing making".
- Section 4.4, paragraph 3: Changed "detected by Laser ... Observatories - LIGO..." to "detected by the Laser ... Observatories LIGO..."
