Biography
Associate Professor Emma Ryan-Weber is an astrophysicist, she leads the intergalactic medium research group at Swinburne. The science focuses on detecting atomic elements in the early, distant Universe.
Ryan-Weber and her team conduct this research using near-infrared spectroscopy towards high redshift quasars on the world's largest telescopes including Keck and the VLT. The team also work on high redshift galaxies and examine their influence on reionization, including their escaping fraction of ionizing radiation.
Ryan-Weber’s doctoral research focused on HI in the local universe – a field where she continues an active interest.

Higher degrees by research
Accredited to supervise Masters & Doctoral students as Principal Supervisor.
PhD topics and outlines
Characterising Lyman Continuum Galaxies: The aim of this PhD project is to measure the escaping flux from galaxies at redshifts of 3 to 4 and to characterise their properties for the first time. The project will involve examining existing data from the Keck telescope. The student will have the opportunity to design and participate in future observing proposals. (Co-supervisor Dr Jeff Cooke)
Honours
Available to supervise honours students.
Honours topics and outlines
Highly ionizing galaxies at redshift 3 – do they have different colours?: The aim of this honours project is to measure the colour of galaxies at redshift 3 and compare galaxies selected in three different ways (Lyman-break, Lyman-continuum and Lyman-alpha emission). The project will involve examining existing data from the Keck telescope multi-object spectrograph MOSFIRE.
