Searching for the First Galaxies


Project Description

Observations with submillimetre telescopes have discovered objects in the early universe that are probably the ancestors of present-day galaxies. These objects have redshifts between 3 and 5 (corresponding to about 1-2 billion years after the Big Bang) and they contain so much interstellar dust that virtually all the optical radiation emitted by the stars in them is absorbed by dust and then re-radiated in the submm waveband. The rates at which stars must be forming in them to explain the exceptional luminosity are typically about 1000 solar masses per year, 300 times greater than the star-formation rate in our own galaxy, enough to make a large galaxy in only 1% of the age of the universe. These are almost certainly proto-galaxies, the ancestors of the spirals and ellipticals we see around us today. To find protogalaxies at even higher redshifts, we need to carry out submillimetre surveys at longer wavelengths. These surveys are on the verge of becoming possible with telescopes such as the Large Millimetre Telescope in Mexico and the Atacama Large Millimetre Array (ALMA) in Chile. In this PhD, the student will use the camera that the Cardiff instrumentation group is building for the Large Millimetre Telescope to carry out a survey that is expected to find these ultra-high-redshift objects. The student will also analyse an ALMA dataset that should also contain some of these objects. The student will then use a variety of telescopes, including the VLT, ALMA, Hubble and the James Webb Space Telescope, to study the protogalaxies that we find. The student must be prepared to travel.
