In this report we review the important progress made in recent years towards understanding
the experimental data on ultra-high-energy (E≳ 1 0 9 GeV) cosmic rays. We begin with a …

Abstract The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
accurately observe ultra-high-energy cosmic rays (UHECRs) and cosmic neutrinos from …

This article presents the design of the Radio Neutrino Observatory Greenland (RNO-G) and
discusses its scientific prospects. Using an array of radio sensors, RNO-G seeks to measure …

We examine the hypothesis of decaying heavy dark matter (HDM) in the context of the
IceCube highest energy neutrino events and recent limits on the diffuse flux of high-energy …

The IceCube neutrino telescope discovered PeV-energy neutrinos originating beyond our
Galaxy with an energy flux that is comparable to that of GeV-energy gamma rays and EeV …

The core mission of the IceCube neutrino observatory is to study the origin and propagation
of cosmic rays. IceCube, with its surface component IceTop, observes multiple signatures to …

We present an update on CRDB, the cosmic-ray database for charged species. CRDB is
based on MySQL, queried and sorted by jquery and table-sorter libraries, and displayed via …

The Probe of Extreme Multimessenger Astrophysics (POEMMA) is a potential NASA
Astrophysics Probe-class mission designed to observe ultrahigh-energy cosmic rays …

In 15 years of data taking, the Pierre Auger Observatory has observed no events beyond 1 0
11.3 GeV. This null result translates into an upper bound on the flux of ultrahigh-energy …

We discuss the acceptance and sensitivity of a small air-shower imaging system to detect
earth-skimming ultrahigh-energy tau neutrinos. The instrument we study is located on top of …
