Hey everyone! So, I did not physically attend the 243rd Meeting of the American Astronomical Society (AAS) held in New Orleans, Louisiana, from January 7th to 11th, 2024. However, my presence was still felt at the conference, thanks to my advisor, Sera Markoff, who presented two interactive posters on my behalf. Let me start by

An exhibition about black holes will open next week at the Valkhof Museum in Nijmegen, where we can think about the mysteries surrounding these extreme gravity objects. Those astrophysical monsters have not only inspired scientists but also artists from all fields, especially in visual arts and music. A great example is the Black Hole Symphony

Few individuals have left as profound a mark on the world as J. Robert Oppenheimer, renowned for his pivotal role in the development of the atomic bomb during World War II. Yet, Oppenheimer’s contributions extend far beyond this infamous accomplishment. Last month, I watched the premiere of Oppenheimer in the cinema and was intrigued by a

Black holes are some of the most fascinating objects in the universe, known for their immense gravity and mysterious nature. While they are famously known for their ability to swallow everything in their vicinity, including light, black holes can also emit powerful beams of energy called jets. Jets are narrow beams of plasma that shoot

Last year, the Event Horizon Telescope (EHT) presented the observations of Sagittarius A* (Sgr A*), located at the Galactic Center of the Milky Way. Their results confirm the presence of a supermassive black hole at the center of our galaxy (see Fig. 1 or this interview). Such an astrophysical object is expected to be described by the Kerr

In this blog, I will introduce the mathematical concept of wormholes in general relativity, the possible implications in serious astrophysical research, and how this became an inspiration for the german science fiction series: Dark. With mathematics, it is possible to duplicate the geometry of spacetime, for example, we can make a copy of the Schwarzschild
