Gravitational waves — ripples in the space-time fabric of the Universe — were predicted by Albert Einstein in 1916. After 100 years of advancements in technology and theory, in 2015, the seminal first detection was made. That first signal came from two black holes, each 30 times more massive than the Sun, elegantly spiralling around each other before crashing together. That signal heralded a new era of gravitational-wave astrophysics, and almost 100 gravitational wave signals have been detected in the subsequent eight years. Yet even with this abundance of detections, there is one big unanswered question in gravitational-wave astrophysics: how do merging binary black holes form? Do the black holes live long lives in each other’s company, or meet only shortly before they merge? In this talk, we will explore the different possible formation channels for binary black holes. We will observe gravitational waves, and draw out details that contain whispers of the biographies of the binaries that produced them. Finally, we will review the most recent results as to the origins of our mergers, and look towards the data-rich future of gravitational-wave astrophysics.

Isobel is a postdoctoral research fellow at the University of Cambridge, where she studies gravitational waves from the collisions of black holes (and sometimes neutron stars). Previously, Isobel did her PhD at Monash University in Melbourne, Australia, and has her MSci in Physics from the University of Birmingham.

Friday 2nd February 2024 Johannes Kepler: his Life and Work

Nicholas Pallett

Friday 2nd February 2024 7.30 pm in the BRLSI, can be attended either in the BRLSI or remotely on Zoom

Johannes Kepler (1571-1630) – astronomer, mathematician, visionary, dreamer, explorer, astrologer is best known for his laws of planetary motion, providing one of the foundations for Isaac Newton’s theory of universal gravitation.
An illustrated talk focusing as much on the personal and family life of this ‘weird genius’, as on his towering scientific achievements and their impact.

Nicholas Pallett B.Sc. has worked mainly as a musician, singer, lyricist & composer in many genres including musical theatre, and in many parts of the world, and more recently as a music teacher/lecturer for the Bristol & Bath Education Authorities.
In the fields of Astronomy and the History of Science he considers himself an ‘amateur’, in the true sense of the word.

Tickets (£6/£3, proceeds to the BRLSI) available shortly.

Thursday 16th November 2023 Dying Stars Seeding the Universe

The Caroline Herschel Prize Lecture 2023

7.00 pm Thursday 16th November 2023 at the 10E 0.17 Lecture Theatre, University of Bath and online via Zoom

Dr Marie van der Sande
University of Leiden

Dr Marie Van de Sande discusses why a multidisciplinary approach is necessary in understanding how stars like our sun die.

Astrochemistry is a vibrant and interdisciplinary field that brings together astronomy, physics, and chemistry. While there is an enormous effort in understanding the chemistry of stellar birth and youth, the chemistry of stellar death is as important: the death throes of sun-like stars enrich the galaxy with fresh material to form the next generation of stars and planets by losing their outer layers by means of a gentle outflow. The presence of a companion star or planet is thought to produce intricate structures within the outflow, giving rise to the beautiful shapes of planetary nebulae, the later stage in the star’s life and an important part of Caroline Herschel’s surveys. This opens up the question of the fate of our own Solar System. To understand exactly how stars like our Sun die and how they are recycled into the next generation of stars and planets, a multidisciplinary approach is necessary, with astrochemistry playing a leading role.”

Background of Speaker

Dr Marie Van de Sande is an Oort Fellow at Leiden Observatory at Leiden University, the Netherlands. She studies the chemistry around dying sun-like stars by developing novel chemical models and comparing their results to observations. Marie obtained her PhD in 2018 from KU Leuven (Belgium), where she stayed on as a fellow of the Research Foundation – Flanders (FWO). She moved to the University of Leeds as a Marie Skłodowska-Curie Individual Fellow in 2021 and relocated to Leiden in September this year.”

The video recording of the lecture is freely available here.

The Caroline Herschel Prize Lectureship was established in 2018 by what is now the Herschel Society, in association with the Royal Astronomical Society, to celebrate Caroline’s memory by supporting promising women astronomers early in their careers. Caroline, William’s younger sister, started out as his assistant, but in time became recognised as an important astronomer in her own right, was the first to be paid as such, and was awarded the RAS Gold Medal in 1828. The Caroline Herschel Prize Lecture is hosted by University of Bath in November in cooperation with the Society as part of the University’s public lecture series.

Friday 1st March 2024 From Algebra to the Secrets of the Universe: the Fascinating life of Mary Somerville

It is an astonishing experience to go back in time and explore the world where study and research for women were forbidden by law. The fascinating life of the Scottish scientist and popular writer Mary Fairfax Somerville (1780-1872) brings us back in this past and, in the same time, describes the fight of one great dame for equal rights and opportunities for women. Her fight was not political, in a sense that she did not try to influence the public opinion with her words or her actions, but by winning the respect of the scientific world. Her extraordinary mathematical talent only came to light through fortuitous circumstances. Barely taught to read and write as a child, all the science she learned and mastered was self taught. By giving this example of scientific competence, she backed the struggle towards education opportunities for women that lead to their access to schools. The Somerville College in Oxford was named in her honor in 1879 and produced famous graduates like Dorothy Hodgkin, Indira Gandhi and Margaret Thatcher.

Elisabetta STRICKLAND is honorary professor at the Department of Mathematics of the University of Rome “Tor Vergata”. She has been Vice-President of the National Institute of Advanced Mathematics (INdAM) from 2007 to 2015. From 2014 to 2022 she has been a member of the Women in Mathematics Committee (WIM) of the European Mathematical Society. She is Honorary President of the Central Committee for the promotion of equal opportunities, workers’ welfare and non discrimination (CUG) of the University of Rome “Tor Vergata”. She is also co-founder of the Gender Interuniversity Observatory GIO over the state Universities in Rome. Since 2016 she is Ambassador of Italy in the Committee of Women in Mathematics (CWM) of the International Mathematical Union.

In 2013 she has been awarded from the Capitoline Administration the Prize “Excellent Women in Rome”.

Monday 4th March 2024 Ada Lovelace: the  Making of a  Computer Scientist

Ada, Countess of Lovelace, (1815-1852), is sometimes called the world’s first computer programmer and has become an icon for women in technology. But how did a young woman in the 19th century, without access to formal school or university education, acquire the knowledge and expertise to become a pioneer of computer science?   The answer lies in the archives in Oxford’s  Bodleian Library, which show a talented an inquisitive child growing into a serious scientist with a remarkable knowledge of cutting edge mathematics of the day, and a fascination with contemporary scientific developments – from mesmerism to photography.

Professor Ursula Martin CBE FREng FRSE is a fellow of Wadham College Oxford, recently retired from Oxford’s mathematical Institute, where she researched a variety of topics at the intersection of mathematics and computer science. Her work on Ada Lovelace’s mathematics has led to several papers and a recent book “Ada Lovelace: the making of a computer scientist” published by Oxford’s Bodleian Library.
