Deep Keck spectroscopy of 1 < z < 2.5 quiescent galaxies: constraining the size growth and the mass assembly of the red sequence

Seminar: Cosmology Seminars | September 2 | 1:10 p.m. | B1 Hearst Field Annex


Sirio Belli, Caltech

Department of Astronomy


The most effective probe of the physical nature of quiescent galaxies is absorption line spectroscopy, which is particularly challenging at high redshift. Using the improved sensitivity of optical and infrared detectors at the Keck observatory, and the multiplex advantage of its new MOSFIRE spectrograph, we have undertaken a new spectroscopic survey of over 100 galaxies selected according to...   More >

The Evolution of Molecular Gas and Star Formation from the Peak Epoch of Galaxy Formation to the Present

Colloquium: Astronomy Colloquia | September 4 | 4:10 p.m. | 2 LeConte Hall


Linda Tacconi, MPE/UCB

Department of Astronomy


Comprehensive and systematic studies of the molecular content of galaxies during the epochs that are associated with the peak (z~1-2), and subsequent winding down (z
