The Role of Magnetic Fields in Protostellar Outflows and Star Formation
Frontiers in Astronomy and Space Sciences, 2019 The role of outflows in the formation of stars and the protostellar disks that generate them is a central question in astrophysics. Outflows are associated with star formation across the entire stellar mass spectrum.

X-ray Insight into High-Energy Processes in Extreme Galactic Nuclear Environment
Universe, 2022 Nuclear regions of galaxies apparently play a disproportionately large role in regulating their formation and evolution. How this regulation works, however, remains very uncertain.

Afterglow Light Curves from Off-Axis GRB Jets in Stratified Circumburst Medium
Universe, 2022 We study the gamma-ray burst (GRB) afterglow light curves produced by an off-axis jet in a stratified circumburst medium and summarize the temporal indices of the coasting phase, the deceleration phase, the Newtonian phase, and the deep Newtonian phase ...

Cosmic Ray Processes in Galactic Ecosystems
Galaxies, 2023 Galaxy evolution is an important topic, and our physical understanding must be complete to establish a correct picture. This includes a thorough treatment of feedback.

The Major Role of Eccentricity in the Evolution of Colliding Pulsar-Stellar Winds
Universe, 2021 Binary systems that host a massive star and a non-accreting pulsar can be powerful non-thermal emitters. The relativistic pulsar wind and the non-relativistic stellar outflows interact along the orbit, producing ultrarelativistic particles that radiate ...

A Review of Recent Observations of Galactic Winds Driven by Star Formation
Galaxies, 2018 Galaxy-scale outflows of gas, or galactic winds (GWs), driven by energy from star formation are a pivotal mechanism for regulation of star formation in the current model of galaxy evolution.

DEATHSTAR—CO Envelope Size and Asymmetry of Nearby AGB Stars
Galaxies, 2022 Low- and intermediate-mass stars evolve into asymptotic giant branch (AGB) stars near the end of their lives, losing mass through slow and massive winds.

Modeling of the Wind/Disk Outflow from Be Stars II: Formation of the Keplerian Disk
Universe, 2022 Computer modeling of the outflow from Be stars is performed. In our approach, processes of turbulence excitation and turbulent viscosity are added to the conventional model of the radiation driven winds.

Ionized Gas Outflows from the MAGNUM Survey: NGC 1365 and NGC 4945
Frontiers in Astronomy and Space Sciences, 2017 AGN feedback, acting through strong outflows accelerated in the nuclear region of AGN hosts, is invoked as a key ingredient for galaxy evolution by many models to explain the observed BH-galaxy scaling relations.
