Project Overview

Quasars, the luminous beacons of the Universe, are powered by accretion onto supermassive black holes. These enigmatic objects provide critical insights into galaxy evolution, black hole formation, and the early Universe. With advancements in wide-field, highly multiplexed spectroscopic surveys, we now stand at the threshold of a new era in quasar research.

This PhD project will leverage cutting-edge datasets from the 4MOST spectrograph on the ESO VISTA telescope and the MOONS spectrograph on the Very Large Telescope (VLT). These surveys, commencing observations in 2025, significantly extend the reach of traditional optical datasets such as those from the Sloan Digital Sky Survey (SDSS). By probing deeper and extending into the near-infrared spectrum, 4MOST and MOONS are uniquely equipped to uncover more distant and obscured quasars.

As a PhD researcher, you will address key questions:

• How abundant are distant and obscured quasars in the Universe?
• How do their properties compare to the well-studied optically selected populations from SDSS?
• What role do these quasars play in the broader context of galaxy formation and evolution?

The project is observationally driven and will use proprietary data from these surveys to explore the physical characteristics of high-redshift and obscured quasars. You will also contribute to the vibrant research community at Southampton, working alongside leading experts in multi-wavelength galaxy surveys and spectroscopy.

Key Responsibilities

As a PhD candidate, you will:

• Analyze spectroscopic data from 4MOST and MOONS to study the properties of high-redshift and obscured quasars.
• Compare findings with existing datasets, including SDSS, to identify differences in quasar demographics and physical properties.
• Contribute to the scientific output of the 4MOST and MOONS Guaranteed Time Observation (GTO) consortia.
• Collaborate with international scientists in the UK, Europe, the USA, and Chile.
• Present research findings at national and international conferences.
• Publish results in high-impact peer-reviewed journals.
• Develop advanced skills in spectroscopy, observational astrophysics, and data analysis.

Entry Requirements

• A strong undergraduate degree (equivalent to a UK 2:1 honours degree or higher) in Physics, Astronomy, or a related discipline.
