Herschel’s Legacy: Breaking Barriers of the Heavens – On gravitational lensing

Prof. Dr. Sherry Suyu (TU München, Max-Planck-Institut für Astrophysik, Garching)

Friday, 21 October 2022, 8 p.m.
Volkssternwarte München, Rosenheimer Str. 145h

In his lifetime, Herschel built and used the heretofore biggest telescopes in the world to measure the Milky way galaxy and to chart thousands of faint nebulae, then unknown to be galaxies in their own right. Today we use those distant galaxies, some of which had first been seen by Herschel, as telescopes themselves – the biggest ones to date and possibly forever – to observe space and time even beyond the pre-relativistic barriers. 200 years from galaxies in telescopes to galaxies as telescopes!

Description

„In March 1781, William Herschel with his powerful telescope spotted a new object in the sky, Uranus, which became the first discovery of a new planet since the antiquity.  We will dive briefly into the lives of William and his sister Caroline Herschel in their passionate pursuit of astronomy.  In the past two centuries since the time of Herschel, astronomers have continued to make ever more powerful telescopes to probe the dark Universe.  Not only human-made telescopes — the heavens have also gifted us with giant cosmic lenses.  A century ago, the first detection of the bending of light by gravity has enabled us to use this effect of „gravitational lensing“ as nature’s cosmic telescope.  We will explore how gravitational lensing can be used to detect extrasolar planets, probe the mysterious dark matter and dark energy, and measure the expansion rate of our Universe.“

 


From H0LiCOW to HOLISMOKES

 

Prof. Suyu / TUMProf. Dr. Sherry Suyu is an assistant professor at TUM for observational cosmology and a research director at the MPIA in Garching. She has become internationally renowned for leading the H0LiCOW programme to measure the expansion rate of the universe using gravitationally lensed quasars and, since 2017, for leading HOLISMOKES, which has nothing to do with religion or addiction, but instead with lensed supernovae.

Therefore, Prof. Suyu is a world leading expert in the field of gravitational lensing, another prediction of Einstein’s that proved true. And we are particularly happy to host a lecture event with her during the series of festive lectures on the occasion of the 75th anniversary of our observatory.

Being a strong advocate of equal opportunity and a women’s representative at TUM, Prof. Suyu sees Caroline Herschel, the sister of William Herschel, as a strong role model for women in science up to this date, considering the conditions of the time. Hence the crosslink to the Herschels in this talk.

Tickets & advance booking


*** Advance booking exclusive for members of the Munich Public Observatory! ***

The October 2022 high profile festive lecture series, comprising noble prize laureate Prof. Genzel and other highly renowned „stars“ of the astronomical scene, takes place on the occasion of the 75th anniversary of the Munich Public Observatory (founded in 1947).
Advance booking is therefore reserved for club members until 15 September.
On 15 September ticket sales (if any are left) start here for the general public.

Members get a personal invitation by 1st of August with a voucher code in order to register for the events.

Tickets: 20 / 10 Euro

Admission from 7.30 p.m. – free seating.

After talk and discussion and if the skies are clear, the guests are invited to have a look at our rooftop observatory and through the telescopes.


Advance ticket sales for the general public start here on 15 September.
