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.

What Is the Role of Stellar Radiative Feedback in Setting the Stellar Mass Spectrum? [PDF]
Astrophysical Journal, 2020 Abstract In spite of decades of theoretical efforts, the physical origin of the stellar initial mass function (IMF) is still debated. Particularly crucial is the question of what sets the peak of the distribution. To investigate this issue, we perform high-resolution numerical simulations with radiative feedback exploring, in particular,

Theoretical Re-evaluations of Scaling Relations between SMBHs and Their Host Galaxies–2. Importance of AGN Feedback Suggested by Stellar Age–Velocity Dispersion Relation [PDF]
Frontiers in Astronomy and Space Sciences, 2017 We present the galactic stellar age—velocity dispersion relation obtained from a semi-analytic model of galaxy formation. We divide galaxies into two populations: galaxies which have over-massive/under-massive black holes (BHs) against the best-fitting ...

Forged by Feedback: Stellar Properties of Brightest Group Galaxies in Cosmological Simulations
The Astrophysical JournalWe investigate how different galaxy formation models impact the stellar properties of brightest group galaxies (BGGs) in four cosmological simulations: R omulus , S imba , S imba -C, and O bsidian .

Shooting for the Stars: Jet-mode Feedback and AGN Jet Deceleration from Stellar Mass Loading
The Astrophysical JournalActive Galactic Nucleus (AGN) jets are thought to be vital ingredients in galaxy evolution through the action of kinetic feedback; however, how narrow, relativistic outflows couple to galaxies remains an open question.

Stellar Population and Energy Feedback in the Supergiant Shell LMC 1 [PDF]
The Astronomical JournalSupergiant shells (SGSs) are the largest interstellar structures in galaxies and inject hot enriched gas into galactic halos. We have studied SGS LMC 1 to determine quantitatively whether stellar energy feedback is adequate to power the formation of an ...
