Evidence for gas-phase metal deficiency in massive protocluster galaxies at z~2.2

no code implementations10 Feb 2021 Zahra Sattari, Bahram Mobasher, Nima Chartab, Behnam Darvish, Irene Shivaei, Nick Scoville, David Sobral

We study the mass-metallicity relation for 19 members of a spectroscopically-confirmed protocluster in the COSMOS field at $z=2. 2$ (CC2. 2), and compare it with that of 24 similarly selected field galaxies at the same redshift.

Dust, gas, and metal content in star-forming galaxies at $z\sim3.3$ revealed with ALMA and Near-IR spectroscopy

no code implementations17 Dec 2020 Tomoko L. Suzuki, Masato Onodera, Tadayuki Kodama, Emanuele Daddi, Masao Hayashi, Yusei Koyama, Rhythm Shimakawa, Ian Smail, David Sobral, Sandro Tacchella, Ichi Tanaka

We conducted sub-millimeter observations with the Atacama Large Millimeter/sub-millimeter Array (ALMA) of star-forming galaxies at $z\sim3. 3$, whose gas-phase metallicities have been previously measured.
