Kinematics of Young Stellar Objects under Various Stellar Feedback
The Astrophysical Journal Supplement SeriesBased on the Gaia Data Release 3 and APOGEE data sets, we investigate the kinematic differences between young stellar objects (YSOs) and their parent clouds in five nearby star-forming regions.

An Exploration of AGN and Stellar Feedback Effects in the Intergalactic Medium via the Low-redshift Lyα Forest [PDF]
The Astronomical Journal, 2023 We explore the role of galactic feedback on the low-redshift Ly α (Ly α ) forest ( z ≲ 2) statistics and its potential to alter the thermal state of the intergalactic medium. Using the Cosmology and Astrophysics with Machine Learning Simulations (CAMELS)

Stellar Evolution with Radiative Feedback in AGN Disks
The Astrophysical JournalStars embedded in the inner parsec region of an active galactic nucleus (AGN) experience extreme accretion conditions that significantly alter their evolution.

Stellar feedback and triggered star formation in the prototypical bubble RCW 120. [PDF]
Sci Adv, 2021 Observations of RCW 120 show that triggered star formation can occur on much shorter time scales than previously thought. Radiative and mechanical feedback of massive stars regulates star formation and galaxy evolution.

Stellar feedback-regulated black hole growth: driving factors from nuclear to halo scales [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Several recent simulations of galaxy formation predict two main phases of supermassive black hole (BH) accretion: an early, highly intermittent phase (during which BHs are under-massive relative to local scaling relations), followed by a phase of ...

Pre-supernova stellar feedback in nearby starburst dwarf galaxies [PDF]
Astronomy & AstrophysicsStellar feedback in dwarf galaxies remains, to date, poorly explored, yet is crucial to understanding galaxy evolution in the early Universe. In particular, pre-supernova feedback has recently been found to play a significant role in regulating and ...

Stellar feedback in a clumpy galaxy at z ∼ 3.4 [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 Giant star-forming regions (clumps) are widespread features of galaxies at z ≈ 1−4. Theory predicts that they can play a crucial role in galaxy evolution, if they survive to stellar feedback for >50 Myr. Numerical simulations show that clumps’ survival

Stellar Multiplicity in an RMHD Simulation with Stellar Feedback
Research Notes of the AAS, 2021 Unlike the Sun, most observed stars are part of a multiple star system, but the formation of such systems is still not well understood. To study this problem, we utilize a run from the STARFORGE simulation suite that simulates the evolution of star ...

Interplay of stellar and gas-phase metallicities: unveiling insights for stellar feedback modelling with Illustris, IllustrisTNG, and EAGLE [PDF]
Monthly notices of the Royal Astronomical SocietyThe metal content of galaxies provides a window into their formation in the full context of the cosmic baryon cycle. In this study, we examine the relationship between stellar mass and stellar metallicity (MZ*R) in the hydrodynamic simulations ...
