Wed 08 Oct 10:00: JWST's View of Star Formation and Mass Growth in Early Galaxies Special Seminar
JWST ’s NIR Cam has transformed our understanding of galaxy structure in the early Universe through unprecedented spatial resolution and sensitivity. Deep wide and medium-band photometry enables precise rest-UV and optical SED constraints, revealing both opportunities and challenges for stellar population modeling.
I will present recent work on the galaxy stellar mass function and total stellar mass density evolution at z > 7, followed by spatially-resolved analysis of 200+ galaxies at z > 5. This reveals how internal structure affects integrated stellar mass estimates through ‘outshining’ effects. I will examine systematic uncertainties in high-redshift SED fitting—including IMF , SPS models, SFH parametrizations, and dust laws—and their impact on derived parameters.
Finally, I will discuss moving beyond traditional SED fitting using machine learning approaches, particularly simulation-based inference (SBI), for large-scale Bayesian inference from wide-area surveys. I will present ongoing work making SBI more accessible for fitting photometry and spectroscopy, enabling rapid constraints on stellar, nebular, and AGN properties in high-redshift galaxies.

Tue 07 Oct 13:00: Clouds across exoplanetary regimes: from hot gas giants to habitable rocky exoplanets
The study of exoplanets has moved from an era of detection to an era of atmospheric characterisation, driven by the launch and commissioning of JWST as well as improvements in ground-based observational facilities. This era of characterisation will involve both deep studies of individual high signal-to-noise exoplanet atmospheres as well as shallow and broad studies of exoplanet atmospheric demographics. In this talk, I will describe how we can leverage both of these characterisation methods alongside 3D models to study exoplanet atmospheres. I will specifically describe the application of detailed 3D GCMs including the impact of clouds on the circulation and emergent properties of hot gas giant and potentially habitable rocky exoplanets. I will describe how the climate dynamics of temperate rocky exoplanets determine how planetary, atmospheric, and host star properties impact their potential for habitability. I will finish by describing the extent to which habitable conditions on rocky exoplanets may be discerned with future observations.

Mon 06 Oct 13:00: Hunting for Cosmic Stasis Within the Cosmological Timeline
Cosmic Stasis is an intriguing phenomenon that may arise in a large class of beyond-the-standard-model theories of the early universe, in which the universe is made of a peculiarly stable admixture of co-existing perfect fluids on long cosmological time scales. In this talk, I will review the theoretical foundation of this new paradigm and discuss how it may manifest itself in a variety of cosmological observables, spreading from the primordial spectrum of scalar perturbations, the evolution of large-scale structures in the post-inflationary universe, the dynamics of big-bang nucleosynthesis, or even the varying equation of state of dark energy today.

Thu 23 Oct 16:00: The Beautiful Confusion: Super-Early Galaxies Seen By JWST
One of the major surprises provided by the first three years of early Universe observations by JWST has been the detection of a stunning overabundance of luminous, and likely massive, galaxies at redshift z10. As the first spectroscopic confirmations are accumulating, it is crucial and timely to investigate these important and yet unknown aspects of early galaxy formation and evolution. At a time at which ALMA has laid the foundations of our understanding, Webb seems to hint at a possibly conflicting scenario. These (apparent?) contradictions need to be solved in the framework of studies that combine theory, cosmological simulations and the most advanced IR/sub-mm observations. I will analyze possible new scenarios and propose preliminary answers to the above questions.
