Stellar feedback shaping the ionized ISM in the nearby galaxies

Oleg Egorov , ARI

Stellar feedback plays an important role in the regulation of the structure, kinematics and chemical abundance of the interstellar medium. Multiple stellar winds and supernovae explosions inject energy and momentum into the interstellar medium. These processes are probable drivers of the turbulence of the ISM. They can also create large holes and superbubbles with sizes varying from several pc to several kpc. Modern integral-field spectrographs allow us to study the resolved properties of the ionized gas, and the high-resolution images from space base telescopes provide information about young stars in the nearby galaxies. Thus, using the combined data set, we can connect directly the ionized gas to the young stellar population. In my talk, I will focus on how the mechanical feedback impacts the small-scale morphology and kinematics of the ISM of nearby galaxies as observed in the PHANGS-MUSE and PHANGS-HST data. Also, I will consider how the feedback from young stars affects the dust content in the nearby galaxies based on the new PHANGS-JWST observations.
