Annual Fast Radio Burst Conference (Montreal, July 2025)

Dear colleagues,

We are excited to announce that the annual Fast Radio Burst (FRB) Conference, FRB 2025, will be hosted by McGill University in Montreal, Canada from July 7–11, 2025.

FRB science has entered a new era: the rate at which FRB sources are precisely localized has surged from a handful to hundreds per year—and will soon reach thousands. With this rapid progress, FRB 2025 is a timely opportunity to discuss the latest advancements and future directions in the field. We especially encourage participation from researchers across a wide range of disciplines, as we explore both the astrophysical origins of FRBs and their utility as cosmological probes.

The conference will be fully hybrid, with low registration fees, particularly for early-career researchers. Abstract submission is open now at https://www.conftool.com/frb2025 with an abstract deadline of April 4th, 2025. Further conference details and confirmed invited speakers are available on our website: https://www.physics.mcgill.ca/frb2025.

We hope you’ll join us for a stimulating week of discussion in vibrant Montreal — whether in person or online!

Cosmic Ecosystems Conference at Perimeter Institute July 28-August 1, 2025

We are pleased to announce the Cosmic Ecosystems conference to be held at Perimeter Institute for Theoretical Physics in Waterloo Ontario from July 28-August 1, 2025.

Website: https://events.perimeterinstitute.ca/event/927/

Important dates

Abstract submission closes: April 23, 2025
Conference dates: July 28 – August 1, 2025

Description

In the past three decades, one of the most transformative insights in cosmology has been the realisation that the formation and evolution processes of cosmic structures such as supermassive black-holes, galaxies and clusters are deeply interconnected with the vast cosmic web that underpins the Universe. These processes do not happen in isolation, but are part of a dynamic ecosystem where matter and energy flow across scales, driving the growth and transformation of cosmic environments. Understanding this complex system, in particular the circum-galactic medium (CGM), is not only key to deciphering how matter is cycled and redistributed through accretion via filaments and outflows from AGN and supernovae, but also crucial for unlocking the next generation of discoveries in areas such as dark matter, the behaviour of the cosmic web, the forces that shape cosmic evolution, and more.

This conference seeks to bring together cosmologists and astrophysicists to foster collaborative exploration of these interconnected cosmic ecosystems. By focusing on how structures interact with their environments across cosmic scales, this conference aims to catalyse groundbreaking discoveries in both astronomy and physics, providing fresh insights into the forces that govern the Universe. Special attention will be given to the joint analysis of large-scale structure and weak gravitational lensing data from surveys such as DESI, Euclid, LSST and Roman with CMB data from the Simons Observatory and CMB-S4, as well as how these can be integrated with observations of JWST, and existing and upcoming observations of X-ray emission, UV/X-ray absorption toward quasars, 21-cm emission, and FRBs.

The goal is to explore the complementarity of these data sets and how their alignment can provide new insights into the interconnected processes shaping cosmic environments, particularly through joint modelling and simulations of many phases of gas and feedback across different regimes. Attention will also be given to bridging the gap between how cosmologists and astronomers approach the CGM, either top-down large-scale and hot and virial phase, vs bottom-up, cooler phases, at smaller scales.

Topics will include:
· Cosmic mass budget, including a census of where the baryons are.
· Effect of baryons on dark matter structures on small and large scales.
· Cosmic evolution of large-scale structures.
· Bridging the gap between different probes.

The time has never been more right to unify these fields, as advances in observation, theory and simulations are poised to open new paths to revealing the cosmos’ most profound mysteries.

Please see the conference website for more information.

Job posting: Post Doctoral Fellowship, Enabling A New Exoplanet Imaging Frontier with SPIDERS

The Role:

Directly imaging exoplanets is a significant challenge, as faint planets are often obscured by their bright host stars. Since 2019, the NRC NEW EARTH laboratory team has developed advanced star-blocking coronagraph masks to rapidly measure and correct optical aberrations directly in the instrument science focal plane, aiming to significantly enhance the detection and characterization of exoplanets.

Post Doctoral Fellowship, ALMA Archival Research on Fragmentation in Star-Forming Cores

The Role:

ALMA’s exquisite angular resolution and sensitivity have opened the door to studying fragmentation within dense star-forming cores in our Galaxy. The few existing analyses of such fragments alongside the incidence rates expected by simulations have provided conflicting results. Large samples of detections are necessary, and a wealth of publicly available data exists in ALMA’s archive waiting to be examined. The successful applicant will harness the computing resources available in the CANFAR Science Platform to process archival ALMA continuum and line emission data of dense cores in nearby molecular clouds to identify, analyze the properties of core fragments, and compare them with those predicted by numerical simulations. With this project, the successful applicant will help to develop ‘big data’ capabilities for the CANFAR Science Platform, as it prepares to become a major computing hub as Canada’s SKA Regional Centre.

Active areas of research at NRC Herzberg include star formation, the interstellar medium, Solar System objects, exoplanets and circumstellar disks, magnetic fields, the Milky Way and Local Group, near-field cosmology and resolved stellar populations, galaxy evolution, supermassive black holes and high redshift galaxies. The Canadian Astronomical Data Centre at NRC Herzberg is involved in many areas including operating a multi-wavelength telescope archive and supporting the cloud-based computing services offered on the CANFAR Science Platform. Current and future ground- and space-based facilities from the UV to radio are represented in our instrument development, which includes radio correlators and signal processing, radio receivers, antenna design, adaptive optics, and UV/optical/near-IR instrumentation.

NRC-Herzberg has a rare combination of staff involved in astronomy research, instrumentation design and development, engineering, data science and observatory support. Our fellowships are intended to leverage this environment to help mentor researchers who will become the leaders necessary to enable ambitious cutting edge astronomy research in the coming decades. We are committed to ensuring that all staff members promptly receive the accommodation they need to do their job and we understand the importance of work/life balance.
