Retrograde predominance of small saturnian moons reiterates a recent retrograde collisional disruption
Edward Ashton, Brett Gladman, Mike Alexandersen & 1 other
What they found64 new irregular moons were found, bringing Saturn's total to 122; small retrograde moons point to a recent collisional break-up.
Why it mattersIt is the family-level picture for Saturn's Norse group.
Family-level context: this paper studies Saturn's irregular moons as a population, including the Norse and Inuit groups, not Hyrrokkin specifically.
What they studied
Canada-France-Hawaii Telescope images from 2019–2021.

A new perspective on the irregular satellites of Saturn - I Dynamical and collisional history
D. Turrini, F. Marzari & H. Beust
What they foundA new dynamical study of Saturn's irregular moons separates original features from later evolution.
Why it mattersIt sets the family-level history for these captured moons.
Family-level context: this paper studies Saturn's irregular moons as a population, not Hyrrokkin specifically.
What they studied
N-body simulations with frequency analysis.
