Astronomy prize recognises work on most luminous galaxies

Caitlin Casey wins outstanding early year prize from the American Astronomical Society.

What excites me about this work is that our discoveries often seem to upend or completely reverse previously-drawn conclusions, and we still have so much to learn. This is, of course, the guiding principle of all scientific investigation and it keeps me driven. I don’t know what we’ll find tomorrow, but I know it'll be exciting.

Gates Cambridge Scholar Caitlin Casey has been awarded an outstanding early-career achievement prize by the American Astronomical Society.

Casey [2007], who is an assistant professor in the University of Texas at Austin’s Department of Astronomy,  was awarded the Newton Lacy Pierce Prize at the Society’s  semi-annual meeting in Washington, D.C.

The organisation awards the prize each year for “outstanding early-career achievement in observational astronomical research based on measurements of radiation from an astronomical object”.

The Society said Casey was selected due to her work “on high-redshift star-forming galaxies and for pioneering new quantitative techniques for determining the importance of submillimeter galaxies in galaxy evolution”. It states: “Her measurements of their total luminosities show that submillimeter galaxies have enormous star-formation rates and represent the birth of the most massive galaxies in today's universe. In addition, she has helped establish the existence of protoclusters at high redshift and quantify their properties.”

Casey, who did her PhD in Astronomy at the University of Cambridge, will deliver a prize lecture at a future conference.

Her group at the University of Texas at Austin is investigating the most luminous galaxies on the edge of the observable universe and seeking to understand how those galaxies are embedded in the large-scale cosmic web. Casey’s work has shown that such extremely bright galaxies are uniquely useful for studying the formation history of galaxy clusters, which are the most massive gravitationally-bound objects in existence.

She says: “What excites me about this work is that our discoveries often seem to upend or completely reverse previously-drawn conclusions, and we still have so much to learn. This is, of course, the guiding principle of all scientific investigation and it keeps me driven. I don’t know what we’ll find tomorrow, but I know it'll be exciting."

I'm currently an Assistant Professor of Astronomy at the University of Texas at Austin. I research galaxy formation and evolution from an observer's perspective; I use the Universe's most luminous galaxies to place constraints on the history of cosmic star-formation, collapse of large scale structure, and the formation of the first galaxies. I'm also interested in teaching pedagogy, how people learn, and how to make STEM fields more equitable and inclusive.

‘Tackle climate change misinformation through computational social science’

Future leaders and researchers need to be urgently trained to tackle climate change misinformation through an interdisciplinary approach that foregrounds computational social science and extends beyond laboratories and university campuses to shape the science-policy interface and rebuild public trust in climate research, according to leading academics. Writing in Nature Human Behaviour, the academics, including Dr Ramit […]

An existential psychological thriller for aesthetes

Christy Edwall’s first novel, History Keeps Me Awake at Night, out in early February, has been described as “an existential psychological thriller for aesthetes and lovers of cultural London and the world… A story cleverly told of a young woman involved in contemporary forms of global voyeurism”. It tells the story of Margit, a London […]

A detective of ancient climate change

Stijn De Schepper is an ancient detective. His job is to investigate past climate change through working his way down the ocean bed, starting with today’s sediment and moving back through thousands of years of Earth’s history.  He maps ancient marine sediments to find out if, why and how the environment changed in the past.

The rich history inside ancient texts

The ancient Greek texts Daniel Hanigan [2019] has been studying for the last three years have been seen as a kind of ancient lonely planet guide, but he found something much more interesting which went to the heart of the ancient Greek experience and how it evolved over time.   He says: “The periploi have […]
