Getting settled in - practical information and necessities

You should maintain your homepage yourself. This is done by clicking 'Manage documents' at the bottom of the page and signing in using your UiO credentials. 

Internet access and email address

  • Your web account and email address at the University of Oslo [format: username@astro.uio.no] will be activated by the IT service group upon your arrival. You will have to go there in person and bring your ID. It may take a couple of days before the user becomes active.

Office and door sign

Door pass and ID card

For foreign employees

For general information, please read carefully the information for international staff.

Registering with Norwegian authorities

  • In order to get an ID card at UiO and for opening a bank account, you will need a national identity number (personnummer). This requires some processing time, and is often a limiting factor for getting settled. Therefor, we urge you to make appointments with the required authorities as early as possible. Please read carefully the Registration with Norwegian authorities pages in which you will find information on how to register at local authorities within set deadlines.  

Norwegian bank account

  • Opening a bank account should be one of your top priorities upon arrival in Norway, especially if your stay exceeds six months. Access to a Norwegian bank account will enable you to receive salary payments and handle your finances in a safe and efficient way.
  • Please read about the procedures on the UiO Bank account pages

Research and outreach


Important: It is of upmost importance to state your affiliation correctly in all of your publications. For ITA employees, this means including the following affiliation: Institute of theoretical astrophysics, University of Oslo. If you publish in a lesser-known peer-reviewed journal, please ensure that the journal is recognised at level 1 or 2 according to the Database for Statistics and Higher Education. Please inform the ITA administration if the journal is not recognised. 

Registering scientific activity

  • CRIStin is the national system used by UiO for registering academic activities and results. You must register all of your journal publications, books, book chapters, talks, posters, media contributions, etc., as the information entered into this system is used to generate reports on scientific activity, including information on collaboration (internally, nationally and internationally). If you have any difficulties using Cristin, you can contact the ITA administration. 

Publication fund for UiO researchers

  • Authors who wish to publish in Open Access (OA) journals will have the opportunity to apply for financial support to cover article processing charges. Read more.


Astronomy is appealing to the general public and we aim at being the main source for astronomy news related to research within our fields. We have good experience scientific outreach for various target groups, and well connected to media. Please contact our current Press and Communication Officer (Martina D'Angelo) for information on how to popularise your research. 

Please do not hesitate to contact the ITA administration if you have any question or encounter problems.
