He discussed the fantastic OPAL program that uses the Hubble Space Telescope to obtain long-time baseline observations of the outer planets to understand their atmospheres.

Can intracluster light, the light from stars that no longer belong to any one galaxy, probe how galaxy clusters grow and how dark matter is distributed?

💡 ISSI International Team 577 around Prof. Nina Hatch has answers: www.issibern.ch/turning-ghos... 🔭

Beneath the starlight that comes from the galaxies themselves one can find a much fainter glow: the intracluster light (ICL).

e.g. the discovery of gravitationally lensed supernovae, the new controversy about the Hubble constant & in particular the data releases of the ESA Gaia mission which allowed to discover many new strongly lensed objects due to the all-sky coverage opening up a multitude of new roads for exploration.
issibern.ch
The first gravitationally lensed quasar — the double Q0957+561A,B — was discovered more than 45 years ago, by now about 400 multiply imaged quasars are known. New developments in recent years make the topic of “strong gravitational lensing” very timely and open up new routes for exploration.

Grüezi and welcome!

We are delighted to welcome Dr. Brian Welch as ISSI Fellow! 🌟

His research uses the James Webb Space Telescope to study how the first galaxies formed the chemical elements that make up our Universe.

Guest book from our team meeting at @issibern.ch on the #BlackHole in our galaxy’s centre, Sgr A*🔭🧪. PhD student Nicole Ford reimagined the river flowing through Bern as a magnetic flux tube in the accretion disk interacting with a current sheet, a potential site of high-energy flaring!
