ALMA Large Program to Investigate C+ at Early Times

Artist's illustration of a galaxy in the early universe that is very dusty and shows the first signs of a rotationally supported disk. In this image, the red color represents gas, and blue/brown represents dust as seen in radio waves with ALMA. Many other galaxies are visible in the background, based on optical data from VLT and Subaru. Credit: B. Saxton NRAO/AUI/NSF, ESO, NASA/STScI; NAOJ/Subaru

Overview: ALPINE (the ALMA Large Program to Investigate C+ at Early Times) is a 70 hour survey with the Atacama Large Millimeter Array (ALMA). The survey measures the far-infrared properties of 118 galaxies in the early Universe. IPAC scientist Andreas Faisst is the U.S. Lead PI, responsible for ancillary data management.

ALPINE (the ALMA Large Program to Investigate C+ at Early Times) is a 70 hour survey with the Atacama Large Millimeter Array (ALMA). The survey measures the far-infrared properties of 118 galaxies in the early Universe. These measurements are used to study the dust and gas properties of these galaxies, to ultimately understand how such galaxies form and evolve over cosmic time.

ALPINE focuses on a time roughly between 1 and 1.5 billion years after the Big Bang (8-10% of the Universe's current age), which corresponds to redshifts (z) between 4 and 6. During this time, galaxies experience a phase of rapid growth in which they build up their stellar mass and other fundamental properties that are seen in today's galaxies. This epoch is therefore important to be studied to understand galaxy evolution.
