Please join us at Rosny Library from 7:30 to 9:30pm for this most interesting presentation.Title: How to see the brightest explosions of the Universe with an optical telescope.
Speaker: Dr. Karelle Siellez is a lecturer in Physics and researcher in Astrophysics at the University of Tasmania. Her areas of research concern the new era of Astrophysics: the multi-messenger era with all its transients, black hole and explosions of massive stars and compact objects. She is French originally, lived in the US for 5 years, and moved to beautiful Tassie where, if she is not up late observing the night sky, she is spending her time on the water sailing or surfing, or in the forest hiking.
Abstract: In 2017 we have wide open the multi-messenger era: a new path to understand the most violent cataclysmic events of our Universe. The first ever multi-messenger was Supernova 1987 that allows the detections of Neutrinos coincident with the Electromagnetic emission through light.
Thirty years later, we observed a revolutionary event: the merging of 2 neutron stars that formed a black hole. Not only did we see light coming out in all wavelengths, but we also detected the associated deformation of the geometry of the Universe through Gravitational Waves.
I will revisit this amazing discovery, and will discuss all of the implications: from our understanding of the Universe to the comprehension of the elements on our planet.
I would like to start a discussion on how we could collaborate between "professional" and "amateurs" astronomers to get more transients such as this one !
Karelle's Fields of Research are:
General relativity and gravitational waves
Cosmology and extragalactic astronomy
High energy astrophysics and galactic cosmic rays

Her presentation will commence at 7.30pm. Her talk will be followed by an informal tea and coffee break and a short presentation of the night sky highlights for the coming month by Education and Outreach Officer Richard Grudzien.
