The VIMOS UltraDeep Survey – a spectroscopic survey of high redshift galaxies
The VIMOS UltraDeep Survey (short: VUDS) is an observational
program to gain spectroscopic measurements for ~10,000 galaxies at high redshift , when the Universe was only between 1- 3 billion years old (today, the
Universe is 13.8 billion years old). This i...

Where is the Dust in Distant Galaxies?
In a previous post w e wrote about the morphology of a galaxy's star light. Most galaxies have matter that we can see in 3 forms: stars , gas , and dust . Figure 1: M51 at optical wavelengths of light. Credit: NASA, ESA,  S. Beckwith (STScI), and The Hubble...

Coming Out of the Dark Ages
Until about 400,000 years after the Big Bang ,  the Universe was mostly full of electrons and protons, zipping in random directions. It was only when the Universe cooled down enough, because of expansion, that electrons and protons had a chance to combine t...

Preparing Multi Object Spectroscopy Observations
Although CANDELS is a photometric survey, many team members have proposed for and been granted observing time for CANDELS sources with to obtain spectroscopy . Such additional data not only provides us with a more accurate measurement of the distances of ga...

Exploring How Galaxies are Transformed
Fig 1: Spiral galaxy M74. Image Credit: NASA When we look at galaxies out in the universe, we find that they come in many different types. Some galaxies have beautiful spiral structure (see Figure 1), while others look like irregular blobs of stars and gas....
