TalkGalaxies and quasars in the early Universe: recent results and future prospects from sub-millimeter observations
In recent years, major changes were done at the IRAM Plateau de Bure interferometer and 30-meter telescope, in particular in the areas of receivers and back...

TalkGalaxies at high z: the MUSE revolution
Thanks to its unique capabilities, the MUSE integral field spectrograph at ESO VLT has given us new insight of the Universe at high redshift. In this talk I...

PublicationGalaxies Going Bananas: Inferring the 3D Geometry of High-redshift Galaxies with JWST-CEERS
The 3D geometries of high-redshift galaxies remain poorly understood. We build a differentiable Bayesian model and use Hamiltonian Monte Carlo to efficiently...

TalkHerMES HFLS3: A dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
How do the first galaxies form and evolve? Optical and near-infrared deep surveys are now finding galaxies at very high redshifts. However, they are typically...

TalkIndiana Jones and where to find relic galaxies
There are galaxies that remain untouched since the ancient Universe. These unique objects, the so-called relic galaxies, are several times more massive than our...

TalkLocalized starbursts in dwarf galaxies produced by impact of low metallicity cosmic gas clouds
Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver of star formation over cosmic history. Except in very dense...

PublicationMeasurements of the Dust Properties in z ≃ 1-3 Submillimeter Galaxies with ALMA
We present Atacama Large Millimeter/submillimeter Array (ALMA) 2 mm continuum observations of a complete and unbiased sample of 99 870 μm selected submillimeter...
