Massive Quiescent Disk Galaxies In The Candels Survey, Aurora Y. Kesseli

Honors Theses

We used data from the GOODS-S field of the CANDELS survey in order to confirm previous studies that found that large fractions of high-redshift galaxies (z ∼ 2) are disk-dominated (McGrath et al. 2008; van der Wel et al. 2011). In the GOODS-S field we selected out all the massive quiescent disk galaxies by imposing a mass limit of M > 10¹⁰M_⊙ and a redshift range of 0.5 ≤ z ≤ 2.5, and then choosing the quiescent red galaxies from a color-color plot. Once we had our sample, we did a qualitative visual classification of each galaxy and …
