Metsähovi Radio Observatory

Metsähovi Science Seminar

Metsähovi Science Seminars consists of seminar talks, journal club sessions and discussions relevant to radio astronomical research and studies at Metsähovi.

The seminars

During the academic year 2023-2024 the Metsähovi Science Seminars are not held periodically, but more sporadically, e.g. related to visits or student theses.

All types of presentations are welcome, including "hard" science presentations, journal club type presentations of interesting papers, travel/conference reports, student presentations, engineering projects and updates of what is going on in Metsähovi.

Contact person: Quentin Salomé [email protected] .

Schedule

Location: MRO seminar room and online using Zoom. (Ask Quentin for details if you haven't received them via Finnish astronomy email lists)

Time: no specific schedule, advertised via observatories' and astrnomy groups' email lists.
