Galaxy winds as a research area investigates large-scale gaseous outflows driven by processes within galaxies, such as stellar feedback from massive stars and supernovae or energy and momentum injection from active galactic nuclei. This field focuses on the multi-phase structure, kinematics, and energetics of these winds, their impact on galaxy evolution, star formation regulation, metal enrichment of the circumgalactic and intergalactic media, and the closing of the baryon cycle. Research combines observational diagnostics across the electromagnetic spectrum with theoretical modeling and simulations to quantify mass-loading factors, escape fractions, and the coupling between radiation, cosmic rays, magnetic fields, and outflowing gas.
Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism enabling galaxies to leak ionizing radiation, which is believed to have played a major role in the ...
In a new study using data from the James Webb Space Telescope (JWST), Prof. Dasyra of the National and Kapodistrian University of Athens, Greece, and her team provided insights into how supermassive black holes affect galaxy ...

An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy's halo. The finding was reported in ...
An international team of astronomers has employed the James Webb Space Telescope (JWST) to perform spectroscopic observations of a luminous quasar known as J1007+2115. They detected a fast outflow originating from the quasar's ...
