Feedback from massive stars is the main driver of secular evolution in galaxies with masses similar to or smaller than the Milky Way, across the entire redshift range. Indeed, state-of-the-art numerical simulations of star-forming molecular clouds and galaxy evolution cannot reproduce key observables (e.g. the star formation rate vs. stellar mass relation) without accounting for stellar feedback. Therefore, feedback from massive stars represents one of the main uncertainties in numerical star formation and galaxy evolution studies.

The missing ingredients towards making significant progress in the field are observational constraints on the numerical models as a function of cosmic time and environment, as well as meaningful ways of comparing models and observations. In view of the ongoing and upcoming dedicated, legacy-value feedback surveys in nearby galaxies, this Ascona meeting brings together observers and theorists, both from the nearby and high-redshift communities. Combining these different communities will enable the problem of stellar feedback to be addressed comprehensively and holistically, thereby greatly improving the predictive power of galaxy evolution models.

Important Information

This meeting was orginally scheduled to take place at the Aspen Center of Physics in January 2021. Due to the global pandemic, the SOC has decided to postpone the meeting to June/July 2022 (exact dates TBD), and move the venue to Ascona, Switzerland.

Important details regarding the meeting are listed below. For futher information, please fill out the contact form below, or send and email to ascona.feedback.galev.meeting@gmail.com. Abstract submission will re-open early 2022. We will monitor the worldwide COVID-19 situation and vaccination efforts closely and provide an updates accordingly (last update: April 2022).

Disruptive or harassing behavior of any kind will not be tolerated. Harassment includes but is not limited to inappropriate or intimidating behavior and language, unwelcome jokes or comments, unwanted touching or attention, offensive images, photography without permission, and stalking.

Violations of this code of conduct policy should be reported to the meeting organizers. Sanctions may range from verbal warning, to ejection from the meeting without refund, to notifying appropriate authorities. Retaliation for complaints of inappropriate conduct will not be tolerated. If a participant observes inappropriate comments or actions and personal intervention seems appropriate and safe, they should be considerate of all parties before intervening.


There are numerous hotels in Ascona, and participants are encouraged to make their own reservations.

The Collegio Papio has a limited amount of rooms available as single or double occupancy for CHF 40.- per person per night. Please contact Anna McLeod for more information and booking. Preference will be given to students on a first-come-first-served basis.

Social Activities

There will be a Welcome & Registration reception on Sunday night from 5:00 to 7:00 p.m.

The conference outing followed by the conference dinner are scheduled for Thursday afternoon/evening, activity and venue TBD.

Ascona and the Canton Ticino are stunningly beautiful and we encourage participants to explore the region during free moments. More information can be found on the Ascona-Locarno tourist info pages, and on the equivalent Ticino info pages.
