CIII]1908 emitters in VANDELS
Combined rest-frame UV spectra of intense CIII] emitters
Some active star-forming galaxies at high redshift show extreme nebular UV emission lines such as CIII]1908 (one of the strongest after Lya). Some of them are believed to be analogs of galaxies responsible for reionization at z>6. In this project, we explore the ultradeep spectra of galaxies at z~2-4 from VANDELS (PI: Pentericci, L. and McLure, R.), a VLT/VIMOS survey, to understand the UV properties of a large sample CIII] emitters.

NIR Follow-up
The UV properties of star-forming galaxies are not fully understood. To better constraint them, we need to combine information from the optical, which from galaxies at z~2-4 is obtained with NIR spectrographs. In this project, we explore the optical properties of CIII] emitters with follow-ups and combine the UV+optical to unveil the properties of these galaxies. Currently, we have data from VLT/Xshooter (PI: Amorin, R) and MOSFIRE (PI: Shapley, A), but we persue to increase our sample.
Local Analogs
Some analogs to these extreme galaxies at high redshift have been found in the local universe but their UV properties have not been explored in large samples. In this collaboration, we use the tools developed for high redshift galaxies to compare with local galaxies observed by CLASSY (PI: Berg, D.), a COS/HST survey.
