To promote scientific discussions during this pandemic, we are organizing an online seminar series, i.e. Copernicus Webinar Series, seeking the most outstanding speakers to introduce innovative ideas and important progress in the field of gravity and cosmology. This series is named after the famous Polish Astronomer, Nicolaus Copernicus, whose discovery eventually marked the dawn of modern science.

We would like to invite you to take part in the upcoming 71st Copernicus Webinar

Time:                  30th November, Tuesday, 3pm CET (10 pm Beijing time, 11 pm JST, 9am ET)

Speaker:            Suvodip Mukherjee (Perimeter Inst. Theor. Phys.)

Title: A New Era of Precision Cosmology using Multi-Messenger Observations

Abstract: The discovery of astrophysical gravitational waves has opened a new avenue to explore the cosmos. I will discuss a few new frontiers in the field of physical cosmology and fundamental physics that can be explored using the LIGO-Virgo-KAGRA network of gravitational wave detectors. I will elucidate how the synergies between electromagnetic probes and gravitational wave probes will play a key role in developing a data-driven model of cosmology in the near future.

and the upcoming 10th Colloquium talk,

Time:             2nd December, Thursday, 2pm CET (9 pm Beijing, 10 pm JST, 8am ET)

Speaker:        Joseph Silk (IAP / JHU / BIPAC, Oxford)

Title: Cosmology from the Moon: two concepts to explore


I will review the prospects for future progress in cosmology. I will give examples of two futuristic experiments. One can obtain the dark ages signature via low frequency radio astronomy on the lunar far side. Attainable angular resolution potentially opens up huge numbers of modes to provide a new and robust probe of inflationary cosmology. A second direction involves a far infrared telescope to search for the elusive deviations from the blackbody spectrum of the cosmic microwave background. This could provide an unprecedented probe of the Universe in its first hundred thousand years. Both concepts could be implemented in future decades via lunar observatories.
