POEMMA-Balloon with Radio: a balloon-born multi-messenger multi-detector observatory

TL;DR

POEMMA-Balloon with Radio (PBR) is a scaled-down, balloon-based multi-messenger observatory designed to detect ultra-high-energy cosmic rays and neutrinos, aiming to enhance multi-messenger astrophysics through a long-duration balloon mission.

Contribution

This paper introduces the PBR concept as a novel, balloon-borne adaptation of the POEMMA mission for extended multi-messenger observations.

Findings

PBR can operate for up to 100 days over the Southern Ocean.

It aims to detect ultra-high-energy cosmic rays and neutrinos.

The mission design includes specific instruments and operational plans.

Abstract

The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is a proposed dual-satellite mission to observe Ultra-High-Energy Cosmic Rays (UHECRs), increasing the statistics at the highest energies, and Very-High-Energy Neutrinos (VHENs), following multi-messenger alerts of astrophysical transient events throughout the universe such as gamma-ray bursts and gravitational wave events. POEMMA-Balloon with Radio (PBR) is a scaled-down version of the POEMMA design, adapted to be flown as a payload on one of NASA's sub-orbital Super Pressure Balloons (SPBs) circling over the Southern Ocean for up to 100 days after a launch from Wanaka, New Zealand. This overview will provide a summary of the mission with its science goals, the instruments, and the current status of PBR.
