Prof. Maurício Richartz, from ABC Federal University, State of São Paulo, Brazil, visited Gr@v in March-April 2023, to discuss analogue models of gravity and other topics. Thank you for your visit Maurício and see you soon!
Astrophysical black holes are consistent with the Kerr metric, but current observations do not rule out small deviations from it. In this work we use the continued fraction method to determine the eigenfrequencies associated with a Kerr-like black hole.
The next decade will see an overwhelming number of cosmological surveys coming online. The Square Kilometre Array Observatory (SKAO) will, among several other science cases, map the distribution of cold neutral Hydrogen in the Universe using its spin-flip transition emission line at rest of 21cm or 1.4GHz and a novel technique called Intensity Mapping (IM).
Miguel attended the IberiCos 2023 meeting in Ponte de Lima, the oldest village in Portugal. Here he is together with former Gr@v member João Rosa.
Gr@v member Miguel Zilhão was the guest for the activity "Meeting with a scientist", organized by the outreach centre Fábrica.The audience was a group of 4th grade students from the Primary Schools of Glória and São Jacinto. They were all very curious about the Universe and asked a lot of interesting questions.
Gr@v Ph.D. student Marco Brito, visited the U. Valencia within the NewFunFiCO Marie Curie Staff Exchange grant, coordinated by our group. [In the photo with his host, former group member Nico Sanchis-Gual]
Our group visited Colégio de Lamas, in Santa Maria da Feira, to explain basic concepts about Earth and Space. Inevitably, the questions end up discussing black holes!
