PhD Position in Extreme-Precision Radial Velocity Instrumentation for Earth-like Exoplanets (HARVY Project)

Opportunity Overview

Join a pioneering project at the forefront of astrophysics and astronomical instrumentation. This initiative aims to enhance the capabilities of extreme-precision radial velocity spectrographs, which are essential for identifying Earth-like exoplanets. In collaboration with the Terra Hunting Experiment consortium, the goal is to overcome challenges posed by stellar variability and provide the research community with unprecedented data access.

Project Background

The HARVY project seeks to establish a new reference design for an extreme-precision radial velocity (EPRV) spectrograph, enabling a comprehensive survey of hundreds of Sun-like stars using a network of telescopes worldwide. This innovative approach promises to maximize efficiency in component design while maintaining compactness and affordability.

Role Responsibilities

The candidate will significantly contribute to the advancement of the HARVY optical design, focusing on the evaluation and optimization of novel optical components. Key responsibilities include:

• Participating in the instrument construction phase, leading subsystem design and production.
• Contributing to the preparation and execution of the on-sky test campaign planned for 2028.
• Collaborating at the intersection of astrophysics, optical design, and instrumentation within a leading research environment at ETH Zurich.

Skills Development

Throughout this role, the candidate will gain valuable expertise in:

• Extreme-precision radial velocity instrumentation
• Optical design and tolerance analysis for high-resolution spectrographs
• Throughput optimization and system-level performance modeling
• Testing of novel optical components and subsystems
• Instrument stability analysis and systematic effect mitigation
• Long-term considerations for stellar variability
• Laboratory validation and on-sky commissioning of astronomical instruments
• Scientific writing and preparation for international collaboration

Qualifications

We seek a candidate with:

• A Master's degree in physics, astrophysics, optics, or a related field
• A strong interest in astronomical instrumentation and exoplanet science
• Relevant experience in optical design, precision measurements, or spectroscopy
• Programming and data analysis skills (e.g., Python, MATLAB, Zemax or similar)
• The ability to work independently and collaboratively within an international team
• Fluency in English, both spoken and written

Institutional Environment
