An international team anchored by the Event Horizon Telescope (EHT) Collaboration, which is known for capturing the first image of a black hole in the galaxy Messier 87, has now imaged the heart of the nearest radio galaxy Centaurus A in unprecedented detail.
The Radboud University and Radboud University Medical Center are sending four ventilators to Namibia, which is severely affected by Covid-19. The country is in the midst of a third wave of the corona pandemic and the number of infections continues to rise.Astronomers from Radboud University have been collaborating with colleagues from the University of Namibia (UNAM) for several years to build the Africa Millimeter Telescope (AMT) at the Gamsberg mountain. They care deeply about Namibia. Together with the Radboud University Medical Center, they have started an action to send medical equipment to Namibia to help with the fight against Covid-19.
Today the KNAW (Royal Netherlands Academy of Arts and Science) announced that it has elected Conny Aerts as a new (foreign) member. Please find a brief biography below (in Dutch only). Another new member is Jana Roithova (1974), who is professor of spectroscopy and catalysis at our Faculty of Science.We congratulate Conny on her election!Conny Aerts (1966)Hoogleraar sterrenkunde, KU Leuven en Radboud UniversiteitConny Aerts bestudeert het inwendige van sterren aan de hand van bevingen aan hun oppervlak. Haar baanbrekende werk heeft ervoor gezorgd dat we de interne structuur en evolutie van sterren beter kunnen modelleren. Ze is een drijvende kracht achter de inzet van ruimtesatellieten om sterren te onderzoeken. Dit heeft tot een schat aan nieuwe ontdekkingen geleid over de massa, omvang, chemische samenstelling en leeftijd van sterren. Naast haar succesvolle wetenschappelijke werk schreef Aerts hét studieboek over astroseismologie, zet ze zich onvermoeibaar in voor genderbalans in de wetenschappelijke wereld en informeert ze het grote publiek over sterrenkunde door haar vele activiteiten op het gebied van wetenschapscommunicatie .
Astronomers Heino Falcke of Radboud University and Sheperd Doeleman of the Harvard-Smithsonian Center for Astrophysics will jointly receive the Henry Draper Medal for their pioneering work, which led to the first image of a black hole.
For decades astronomers have been spotting bursts of electromagnetic radiation coming from black holes. They assumed those are the result of stars being torn apart, but they have never seen the silhouette of the actual material ligaments. Now a group of astronomers, including lead author Giacomo Cannizzaro and Peter Jonker from SRON/Radboud University, has for the first time observed spectral absorption lines caused by strands of a spaghettified star.
Astronomer Sara Issaoun will receive the ‘For Women in Science Rising Talent Prize 2021’. This prize is awarded annually to young, talented female researchers in The Netherlands to benefit their academic career.
In April 2019, scientists released the first image of a black hole in the galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told. Data from 19 observatories are being released that promise to give unparalleled insight into this black hole and the system it powers, and to improve tests of Einstein’s General Theory of Relativity.
Sara Issaoun awarded an Einstein Fellowship. Fellows are named to one of three sub-categories corresponding to three broad scientific questions NASA seeks to answer about the universe:How does the universe work? – Einstein FellowsHow did we get here? – Hubble FellowsAre we alone? – Sagan Fellows
2021 Petrie Prize LectureCASCA is pleased to announce Dr. Heino Falcke as the 2021 R.M Petrie Prize Lecturer.For decades Dr. Falcke has an international leader in the quest to use very-long baseline interferometry to image the shadow of a black hole. These efforts culminated in the stunning images of the supermassive black hole in M87 produced by the Event Horizon Telescope (EHT). Dr. Falcke is a member of the Royal Netherlands Academy of Arts and Sciences, and in 2019 won the Breakthrough Prize for Fundamental Physics as part of the EHT collaboration.CASCA is honoured to have Dr. Falcke give the Petrie Prize lecture.
