MEETING VENUE

The meeting will be held at the University Observatory, home to the Astrophysics department. It’s well within the city and Vienna has excellent public transport.

ADDRESSES AND HOW TO REACH

The University Observatory (google "Universitätssternwarte Wien") is a real gem, its address is "Türkenschanzstrasse 17" in the 18th district (1180 Vienna). The best way to reach it is to use tramway lines 40 or 41 to "Aumannplatz", then take a walk uphill.

GENERAL TRAVEL INFORMATION

There are many ways to reach Vienna. You can even come on the Danube by boat, but we expect most participants to come via the airport or by train.
1) Vienna airport is located about 20 km east of the town. There are direct shuttle trains (the "CAT"), normal trains (cheapest option) and buses to the city center. There are also several taxi companies there, but unless you arrive at 1 a.m. in the night there's not really a reason to use them. Same for car rental, it's really not needed. A second airport close to Vienna is Bratislava, which is connected to Vienna by buses (1 hour).
2) by Train: The two relevant railway stations for international travel are the main station ("Hauptbahnhof") and the "Westbahnhof". In either case, they are already in the city and you would then switch to the subway or to the tram anyway.
If you really come by car, note that parking is nonfree and time-limited, except of course if your hotel offers parking.

HOTELS

We refer to the online booking service of your choice. Thousands of hotels will be happy to welcome you, public transport is always close and there are no really bad areas in Vienna. Of course we will help if you have special needs.

Code of Conduct

All participants are requested to follow these guidelines:

• All participants are expected to behave professionally and to be respectful – critique ideas not people.
• All communication should be appropriate for a professional audience taking into account the many different backgrounds and perspectives of the participants.
• Participants may share the contents of talks/slides via social media unless speakers have asked that specific details/slides not be shared. If participants wish to share photos of a speaker on social media, it is strongly recommended that they first get the speaker’s permission.

The Austrian Academy of Sciences does not tolerate unprofessional or inappropriate behaviour or statements. This includes but isn’t limited to: sustained disruption of talks, comments related to individual characteristics, background or identity, and photography or recording of an individual without consent.

Meeting organisers and chairs bear a particular responsibility in ensuring that the code of conduct is followed.

• The Local Organising Committee members are designated as the contact points for all matters related to this code. Participants can report any violation of these guidelines to these designates in confidence.
• Should a participant witness behaviour they suspect may be unprofessional or inappropriate, it is recommended that they approach the affected person as soon as possible to support and help them. The witness can encourage the affected person to report the unprofessional or inappropriate behaviour but should be guided by that person on their preferred course of action.
• Anyone requested to stop inappropriate behaviour is expected to comply immediately. In serious cases, a participant may be asked to leave the event or, in the case of online participation, the removal of meeting credentials.
• In the case where the unprofessional or inappropriate behaviour involves an IWF staff member, the Human Resources Department of the Austrian Academy of Sciences may be contacted for further guidance on the applicable policies and means of action.
