The smallest galaxies

Submitter: Tom Oosterloo
Description: Today, Katarina Kovac will defend her PhD thesis ("Searching for the lowest mass galaxies: an HI perspective") at the Rijksuniversiteit Groningen. In her thesis, she studies the properties of the smallest galaxies known. For this, she used more than 1000 hours of WSRT time to search for these small galaxies. One of her results is that very small galaxies exist, but fewer than perhaps expected. The figure shows the distribution of gas masses of the small galaxies she detected (the dots), and are compared to other studies (the lines).
