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 July 11-15 2022, 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 is now open and will close on February 20th, 2022. (last update: January 2022).

Abstract submission

Abstract submission is now closed, the deadline was February 20th, 2022. Please note that we received about three times more abstracts than the number of expected participants. The SOC is finalizing abstract selection and notifications about successful abstracts will be sent in the week of March 21.


The program is available here.


The meeting will take place in the halls of the historical Collegio Papio in Ascona. The Collegio is located a short walk from the Lago Maggiore and the scenic Piazza.

Travel information

By plane to Milano Malpensa: this is the closest airport to Ascona, it is about 1.5 hours by car. Note that this requires you to cross the Italy-Switzerland border. To get to Ascona you can rent a car, book a taxi, or take the TILO train to Locarno via Bellinzona (from Locarno it is a short bus to Ascona). The LOC is currently looking into the possibility of organizing a collective bus around 12 - 1 pm on Sunday July 10th from Malpensa to Ascona.
By plane to Zurich Airport: From Zurich Airport you can take public transport (train to Locarno, then short bus from Locarno to Ascona). This beatuiful 2.5 hour journey will take you across the scenery of the Alps.
By train from European countries: The closest train station is Locarno, from where a short bus ride will take you to Ascona.


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.
