Galaxies at the Dawn of Time with JWST – Dr. Leonardo Ferreira, UVic Postdoc

Posted by as UVic Meetings

Date/Time: Wednesday March 13, 2024 starting at 7:30PM

Location: University of Victoria, Bob Wright Centre, Lecture Theatre A104. Park in Lot 1 (pay parking) and cross Ring Road.

The new James Webb Space Telescope (JWST) brought upon us a golden era for the study of distant galaxies. For the first time, we are capable of seeing the visible light of galaxies during the first billion years of the Universe. Understanding their shapes and forms, and how they changed since this epoch, reveals not only how they formed and evolved, but how our own Universe evolved as well.

This talk will highlight groundbreaking discoveries made with JWST and illustrate how they alter our understanding of the cosmos compared to the pre-JWST era. We will also address misconceptions that have arisen in the mainstream media regarding these new insights into cosmology and how our concept of galaxies has evolved dramatically since 1920.

Biography: Leonardo Ferreira was born in Brazil and pursued an undergraduate degree and master’s degree in physics at the Federal University of Rio Grande, where he first began his work on the morphology of galaxies. He then moved to the UK for his PhD studies in Astronomy, focusing on how galaxies evolved across cosmic time. In 2023, Leonardo joined the University of Victoria as a Postdoctoral Fellow, working within Prof. Sara Ellison’s group on the topics of galaxy evolution through merging interactions. Leonardo has led pioneering studies on the morphology of distant galaxies using JWST and remains actively involved in this research area.

President’s Message – Feb 2024

Chris Gainor on Observatory Hill - May 7, 2022
Chris Gainor on Observatory Hill

This message marks my return to the presidency of the Victoria Centre after nearly 20 years away from the job. While it is not unprecedented for someone to serve separate terms as President of the Victoria Centre, it has only happened a handful of times in our 110 years of existence.

The Victoria Centre and the RASC in general have just gone through four very difficult years due to the COVID-19 pandemic and its after-effects.

We had to give up in person meetings and events for much of that time. Many in person activities returned in 2022, and last year, our monthly meetings at the University of Victoria and our annual banquet came back. One very positive legacy of the pandemic for our centre is the set of changes to our weekly Astronomy Café gatherings, which kept us going through the difficult days of lockdowns and can now can be attended in person or by Zoom.

Many people made it possible for the Victoria Centre to get through the past four years – including Reg Dunkley and Randy Enkin, who both served as President during that time, including an unprecedented three years in that office for Randy. They had help from many other people, many of whom still serve on the Centre Council. I would like to thank them all.

I’m very pleased to note that one of those members who has worked quietly and effectively in the background for many years – Alex Schmid – is receiving a long overdue recognition this year in the form of the Newton-Ball Award.

It can be argued that the Victoria Centre is now stronger and better than it was when the pandemic started in 2020. There’s Astronomy Café, much-needed updates to our constitution and governance, and continued improvements to the Victoria Centre Observatory. And many of our members, notably Lauri Roche, have worked hard to get the Friends of the DAO and the Centre of the Universe through the pandemic years.

I deserve very little credit for this great work at the Centre level, since I have been volunteering mainly at the National level over the past decade. As we all know, the pandemic landed a few direct hits on the National society that are still being absorbed, and I am continuing to help out there as Chair of the Editorial Board. Lauri and our National Reps are also doing a great job ensuring that our Centre is prominent in National affairs.

This year we can look forward to exciting events such as the April 8 solar eclipse and International Astronomy Day on May 18 at the Royal BC Museum, as well as challenges like our Star Party this summer.

I’m glad to be rejoining my many friends in the Victoria Centre as we carry on our work sharing astronomy with our community and with our own explorations of the universe.

Certificates of Recognition and Excellence for 2023

Congratulations to all the award winners who were announced at the RASC Victoria Centre Annual General Meeting held Feb 12, 2025!

Chris Purse – Certificate of Appreciation – Since the outbreak of the Covid Pandemic in 2020, Chris helped implement Astro Cafe Zoom sessions and has scheduled, hosted and coordinated these meetings. This contribution ensured that the Victoria Centre remained active and connected during a challenging interlude and has emerged as a preferred way for many to attend sessions.

David Payne  – Certificate of Appreciation – FOR organizing, coordinating, and executing a very successful 2023 Island Star Party at Bright Angel Park. Dave navigated bureaucratic hurdles and logistical challenges along the way. As a result, the many who attended will fondly remember this special event.

David Lee – Token of Appreciation – the Victoria Centre “renaissance Man” – in recognition of his many and wonderful contributions.

Lauri Roche – Token of Appreciation – the Victoria Centre “Energizer Bunny” – in recognition of her many and wonderful contributions.

Award of Excellence in Astro-Imaging – TO Ken McGill FOR his black and white image of the Horsehead Nebula and Neighbourhood.

Award of Excellence in Astro-Sketching – TO Bill Weir FOR his Comet C/2022 E3(ZTG) sketched on Feb 15, 2023 Using a Televue NP101 Refractor at 90x.

Installing gear on the 16″ Obsession – Miles analyzing the next step

RASC National Ken Chilton Prize in recognition of a significant piece of astronomical work carried out or published recently – TO Chris Gainor. His book Not Yet Imagined, documents the history of the Hubble Space Telescope. Citation

Ernie Pfannenschmidt Award for Telescope Making – TO Miles Waite FOR many improvements to the VCO 20 Inch Obsession Telescope including attaching digital setting circles and designing bumpers to safeguard these delicate sensors, as well as devising a customized system to stabilize the platform.

Newton-Ball For Distinguished Service to the Victoria Centre RASC – TO Alex Schmid – Alex has been an active member of the Victoria Centre for over 30 years. Accompanied by his iconic handmade Newtonian telescope, Alex has been introducing treasures of the night sky to the Public at DAO Star Parties for decades. His custom crafted tray at the VCO allows eyepieces (to be) safely stowed and readily available. As the Victoria Centre librarian he also prepares coffee, cookies, and wonderful cakes for monthly meetings at UVic. Alex also provides technical support at the Astro Cafe and serves as a Director at Large on Council. The Victoria Centre is very appreciative for the many contributions Alex has made over the years.
