DOI: 10.1093/mnras/stac936
Abstract: Observations of the neutral atomic hydrogen (H i) in the nuclear starburst galaxy NGC 4945 with MeerKAT are presented. We find a large amount of halo gas, previously missed by H i observations, accounting for 6.8% of the… read more here.

DOI: 10.1103/physrevd.104.083013
Abstract: The detection of high-energy astrophysical neutrinos and ultra-high-energy cosmic rays (UHECRs) provides a new way to explore the sources of cosmic rays. One of the highest energy neutrino events detected by IceCube, tagged as IC35,… read more here.
