Aurélie Torti

PhD student

PhD student working under the supervision of Prof. Manuel Aravena. My current research: understanding the properties of high-redshift galaxies and their environment, using data from ALMA, VLT, ATCA, and JWST. I am particularly interested in how the environment influences galaxy evolution, both in blank fields and in overdense structures.

Projects

• Gas-selected galaxies in the COSMOS-Webb field: Using ALMA Band 6 data from the CHAMPS survey to study morphologies, gas fractions, and AGN activity in galaxies at high redshift.
• The SPT2349-56 protocluster at z=4.3: Investigating the properties of galaxies in an overdense environment using ALMA, ATCA, and JWST imaging, with a comparative approach to field galaxies.

Highlights

Main quest: Explore a dwarf galaxy with JWST
Status: Completed
Required: multi-band source extraction (Source-Extractor), galaxy light modeling (GALFIT), compact stellar structure analysis (PEGASE)
Reward: Proto-cluster candidated ages unlocked

Results feeding into upcoming publications.

Publications

Active side quest: Write first paper
Status: From data to draft
Required: 3 figures, 2 tables, and 1 exhausted PhD student
Reward: Achievement “Publish or Perish”

Stay tuned for future attempts.

Extracurricular activities

When not charting galaxies, I’m leveling up in:

• Science communication: spreading knowledge across the galaxy
• Environmental advocacy: rallying for sustainable cosmic stewardship
• Amateur astronomy, horse riding, climbing, reading, gaming, and tech scouting: side quests to recharge and explore new frontiers
• Championing diversity, inclusion, and wellbeing in the academy: forging alliances for a better research realm.
