Stellar feedback and triggered star formation [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractYoung, massive stars influence their ambient medium through winds and radiation. The outcome of this feedback depends on the number of massive stars in a star cluster and on the density of the ambient medium. This contribution is based on a comparison of observations to the results of numerical simulations.

The sensitivity of stellar feedback to IMF averaging versus IMF sampling in galaxy formation simulations [PDF]
, 2020 Galaxy formation simulations frequently use Initial Mass Function (IMF) averaged feedback prescriptions, where star particles are assumed to represent single stellar populations that fully sample the IMF.

Delayed Massive-star Mechanical Feedback at Low Metallicity
The Astrophysical Journal, 2023 The classical model of massive-star mechanical feedback is based on effects at solar metallicity ( Z _⊙ ), yet feedback parameters are very different at low metallicity.

The Effects of Stellar and AGN Feedback on the cosmic star formation history in the Simba Simulations [PDF]
Monthly notices of the Royal Astronomical SocietyUsing several variants of the cosmological Simba simulations, we investigate the impact of different feedback prescriptions on the cosmic star formation history.

Teachers’ translanguaging practices in providing written corrective feedback: An exploratory study of learners’ affective engagement with feedback [PDF]
, 2023 The present study investigated five intermediate English learners’ affective engagement with teacher-generated written corrective feedback. In addition, the mediating effects of the teacher’s translanguaging practices were examined.

Black holes on FIRE: stellar feedback limits early feeding of galactic nuclei [PDF]
, 2017 We introduce massive black holes (BHs) in the Feedback In Realistic Environments (FIRE) project and perform high-resolution cosmological hydrodynamic simulations of quasar-mass haloes [Mhalo(z = 2) ≈ 1012.5 M⊙] down to z = 1.
