Kinematics of Young Stellar Objects under Various Stellar Feedback

The Astrophysical Journal Supplement Series
Based 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

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 feedback efficiencies: supernovae versus stellar winds [PDF]

, 2016
Stellar winds and supernova (SN) explosions of massive stars ('stellar feedback') create bubbles in the interstellar medium (ISM) and insert newly produced heavy elements and kinetic energy into their surroundings, possibly driving turbulence.

Invertible Neural Networks in Astrophysics [PDF]

EPJ Web of Conferences, 2022
Modern machine learning techniques have become indispensable in many fields of astronomy and astrophysics. Here we introduce a specific class of methods, invertible neural networks, and discuss two specific applications, the prediction of stellar ...

Bringing stellar evolution & feedback together: summary of proposals from the Lorentz center workshop, 2022 [PDF]

, 2023
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as "feedback." Due to the complexity of both stellar evolution and the physics of larger astrophysical structures, there remain many ...

The Cusp–Core Problem in Gas-Poor Dwarf Spheroidal Galaxies

Galaxies, 2021
This review deals with the inconsistency of inner dark matter density profiles in dwarf galaxies, known as the cusp–core problem. In particular, we aim to focus on gas-poor dwarf galaxies.

Stellar Feedback, AGN Feedback and Fluid Microphysics in Galaxy Evolution [PDF]

, 2019
Understanding how the baryonic physics affects the formation and evolution of galaxies is one of the most critical questions in modern astronomy. Significant progress in understanding stellar feedback and modeling them explicitly in simulations have made

Fictions, Conditionals, and Stellar Astrophysics [PDF]

, 2013
This article argues in favour of an inferential role for fictions in scientific modelling. The argument proceeds by means of a detailed case study, namely models of the internal structure of stars in stellar astrophysics.
