“Studying the Dawn of Galaxy Formation: New Insights and Challenges from Next-Generation Observatories”, Mon 13 Nov 2023, 8 pm

A Cork Astronomy Club public lecture held in UCC’s Ashley Cummins Building

Cork Astronomy Club is delighted to welcome back Dr Michael Tremmel to give his assessment of the impact of the James Webb Space Telescope (JWST).   What do we know now that we didn’t know two years ago, and what do we hope to find out next? 

Dr Tremmel will go on to outline the current cutting edge of data, not only from JWST but also from upcoming telescopes ─ Vera Rubin and the Legacy Survey of Space and Time, Euclid, WFIRST, LISA (not a telescope per se but a gravitational wave detector).  He will ask, where are we going in the near future and what challenges does this pose for astrophysicists? Abstract below.

Dr Tremmel lectures in Galactic and Extragalactic Astrophysics at UCC’s School of Physics.  He’s a computational astrophysicist studying galaxy evolution and supermassive black holes using cosmological simulations.  Held a postdoctoral fellowship at Yale University.

Below, Dr Tremmel rescuing Schrödinger’s cat.  We’ve used this one before but we like it so much that we don’t apologise for using it again.  

Where and when

Venue: UCC’s Ashley Cummins Building, near UCC’s College Road entrance. Previously known as Civil Engineering buidling.   Directions here.

Start time is 8 pm prompt, so please arrive 10 minutes early.

This lecture is open to all. There will also be club announcements and a sky this month presentation, and if you are new to our Club you will get a feel for our activities.

When we finish at 9.45, you can stay and chat for a few minutes after the end of the formal meeting, with tea and coffee served.



I give an overview of results from the last year of JWST observations of galaxies and black holes and preview some of the science coming from near-future observatories like Vera Rubin, Euclid, the Roman Space Telescope, and the Later Interferometer Space Antenna. The wealth of new data coming in the next decade from various astrophysics missions stands to revolutionize our view of the Early Universe (and, really, it already has!), in particular our theories of the formation of the first galaxies, stars, and massive black holes. This unprecedented view, which will come from both light and gravitational waves, will present new challenges to our models of how galaxies form. From the simulation side, this new era of multimessenger astrophysics will require advancements in our theoretical models in order to fully interpret and contextualize these new observations.
