Early career researchers win major European funding

Of 3,500 proposals reviewed by the ERC, only 14% were selected for funding – Cambridge has the highest number of grants of any UK institution.

ERC Starting Grants – totalling nearly €780 million – support cutting-edge research in a wide range of fields, from life sciences and physics to social sciences and humanities.

̽��ֱ��awards help researchers at the beginning of their careers to launch their own projects, form their teams and pursue their most promising ideas. Starting Grants amount to €1.5 million per grant for a period of five years but additional funds can be made available.

In total, the grants are estimated to create 3,160 jobs for postdoctoral fellows, PhD students and other staff at host institutions.

Cambridge’s recipients work in a wide range of fields including plant sciences, mathematics and medicine. They are among 494 laureates who will be leading projects at universities and research centres in 24 EU Member States and associated countries. This year, the UK has received grants for 50 projects, Germany 98, France 49, and the Netherlands 51.

Cambridge’s grant recipients for 2024 are:

Adrian Baez-Ortega (Dept. of Veterinary Medicine, Wellcome Sanger Institute) for Exploring the mechanisms of long-term tumour evolution and genomic instability in marine transmissible cancers

Claudia Bonfio (MRC Laboratory of Molecular Biology) for Lipid Diversity at the Onset of Life

Tom Gur (Dept. of Computer Science and Technology) for Sublinear Quantum Computation

Leonie Luginbuehl (Dept. of Plant Sciences) for Harnessing mechanisms for plant carbon delivery to symbiotic soil fungi for sustainable food production

Julian Sahasrabudhe (Dept. of Pure Mathematics and Mathematical Statistics) for High Dimensional Probability and Combinatorics

Richard Timms (Cambridge Institute for Therapeutic Immunology and Infectious Disease) for Deciphering the regulatory logic of the ubiquitin system

Hannah Übler (Dept. of Physics) for Active galactic nuclei and Population III stars in early galaxies

Julian Willis (Yusuf Hamied Department of Chemistry) for Studying viral protein-primed DNA replication to develop new gene editing technologies

Federica Gigante (Faculty of History) for Unveiling Networks: Slavery and the European Encounter with Islamic Material Culture (1580– 1700) – Grant hosted by the ̽��ֱ�� of Oxford

Professor Sir John Aston FRS, Pro-Vice-Chancellor for Research at the ̽��ֱ�� of Cambridge, said:

“Many congratulations to the recipients of these awards which reflect the innovation and the vision of these outstanding investigators. We are fortunate to have many exceptional young researchers across a wide range of disciplines here in Cambridge and awards such as these highlight some of the amazing research taking place across the university. I wish this year’s recipients all the very best as they begin their new programmes and can’t wait to see the outcomes of their work.”

Iliana Ivanova, European Commissioner for Innovation, Research, Culture, Education and Youth, said:

“ ̽��ֱ��European Commission is proud to support the curiosity and passion of our early-career talent under our Horizon Europe programme. ̽��ֱ��new ERC Starting Grants winners aim to deepen our understanding of the world. Their creativity is vital to finding solutions to some of the most pressing societal challenges. In this call, I am happy to see one of the highest shares of female grantees to date, a trend that I hope will continue. Congratulations to all!”

President of the European Research Council, Prof. Maria Leptin, said:

“Empowering researchers early on in their careers is at the heart of the mission of the ERC. I am particularly pleased to welcome UK researchers back to the ERC. They have been sorely missed over the past years. With fifty grants awarded to researchers based in the UK, this influx is good for the research community overall.”

Nine Cambridge researchers are among the latest recipients of highly competitive and prestigious European Research Council (ERC) Starting Grants.

Webb detects most distant black hole merger to date

sc604 — Thu, 16 May 2024 17:34:22 +0000

Astronomers have found supermassive black holes with masses of millions to billions times that of the Sun in most massive galaxies in the local Universe, including in our Milky Way galaxy. These black holes have likely had a major impact on the evolution of the galaxies they reside in. However, scientists still don’t fully understand how these objects grew to become so massive.

̽��ֱ��finding of gargantuan black holes already in place in the first billion years after the Big Bang indicates that such growth must have happened very rapidly, and very early. Now, the James Webb Space Telescope is shedding new light on the growth of black holes in the early Universe.

̽��ֱ��new Webb observations have provided evidence for an ongoing merger of two galaxies and their massive black holes when the Universe was just 740 million years old. ̽��ֱ��system is known as ZS7.

Massive black holes that are actively accreting matter have distinctive spectrographic features that allow astronomers to identify them. For very distant galaxies, like those in this study, these signatures are inaccessible from the ground and can only be seen with Webb.

“We found evidence for very dense gas with fast motions in the vicinity of the black hole, as well as hot and highly ionised gas illuminated by the energetic radiation typically produced by black holes in their accretion episodes,” said lead author Dr Hannah Übler of Cambridge’s Cavendish Laboratory and Kavli Institute for Cosmology. “Thanks to the unprecedented sharpness of its imaging capabilities, Webb also allowed our team to spatially separate the two black holes.”

̽��ֱ��team found that one of the two black holes has a mass that is 50 million times the mass of the Sun. “ ̽��ֱ��mass of the other black hole is likely similar, although it is much harder to measure because this second black hole is buried in dense gas,” said team member Professor Roberto Maiolino, also from the Kavli Institute.

“Our findings suggest that merging is an important route through which black holes can rapidly grow, even at cosmic dawn,” said Übler. “Together with other Webb findings of active, massive black holes in the distant Universe, our results also show that massive black holes have been shaping the evolution of galaxies from the very beginning.”

̽��ֱ��team notes that once the two black holes merge, they will also generate gravitational waves. Events like this will be detectable with the next generation of gravitational wave observatories, such as the upcoming Laser Interferometer Space Antenna (LISA) mission, which was recently approved by the European Space Agency and will be the first space-based observatory dedicated to studying gravitational waves.

This discovery was from observations made as part of the Galaxy Assembly with NIRSpec Integral Field Spectroscopy programme. ̽��ֱ��team has recently been awarded a new Large Programme in Webb’s Cycle 3 of observations, to study in detail the relationship between massive black holes and their host galaxies in the first billion years. An important component of this programme will be to systematically search for and characterise black hole mergers. This effort will determine the rate at which black hole merging occurs at early cosmic epochs and will assess the role of merging in the early growth of black holes and the rate at which gravitational waves are produced from the dawn of time.

These results have been published in the Monthly Notices of the Royal Astronomical Society.

An international team of astronomers, led by the ̽��ֱ�� of Cambridge, has used the James Webb Space Telescope to find evidence for an ongoing merger of two galaxies and their massive black holes when the Universe was only 740 million years old. This marks the most distant detection of a black hole merger ever obtained and the first time that this phenomenon has been detected so early in the Universe.
