Research Highlights
I research the baryon cycle and galactic outflows across the majority of the history of the Universe, from redshift z~0 (now) to z~6 (less than 1 billion years after the Big Bang), using spectroscopic data spanning rest-frame UV to submillimeter wavelengths.
I am currently an active member of 3 international teams:
- XQR-30 (The Ultimate XSHOOTER Legacy Survey of Quasars at the Reionization Epoch): this survey obtained XSHOOTER spectra of 30 quasars at 5.8 < z < 6.6, from which I produced the largest catalog of the metal absorbers at z > 5. These data provide key insights into chemical enrichment and the ultraviolet background near the epoch of reionization (read more).
- CRISTAL ([CII] Resolved Ism in STar-forming galaxies with ALma): using ALMA [CII] observations of 19 main sequence galaxies at 4.5 < z < 5.5, I am investigating the incidence and properties of cold, neutral outflows in the early Universe.
- Blue Jay: A JWST survey providing long-slit optical-to-near-infrared spectral of approximately 150 main sequence galaxies at z~2, providing the first comprehensive view of the absorption line properties of galaxies at this epoch. We found the first evidence for widespread, powerful AGN-driven neutral gas outflows which may be a dominant driver of early fast quenching (read more).
