Observing the night sky with large telescopes

I have been enjoy writing telescope proposals and observing with all different kinds of telescopes. I have experience with nearly all large (>5-meter) optical/near-infrared telescopes all over the world, and am a frequent user of James Webb Space Telescope, Hubble Space telescope (HST), Chandra X-ray Observatory (CXO), and Atacama Large Millimeter/submillimeter Array (ALMA).
Currently, I am leading major efforts to map the large scale environment of the most distant quasars with James Webb Space Telescope, Atacama Large Millimeter/submillimeter Array (ALMA), Magellan-Baade/IMACS and Subaru/HSC, to investigate the host galaxies of the earliest supermassive black holes with ALMA, and to characterize the accrection properties of the earliest supermassive black holes with CXO.
I am one of the core developers of the Python Spectroscopic Data Reduction Pipeline: PypeIt. This pipeline supports 20+ spectrographs with more spectrographs are being developed. Everyone are encouraged to try this purely Python based pipeline and please consider to cite DOI: 10.5281/zenodo.3743493 and our JOSS paper if you use PypeIt for your publications. If you have problems, we have a very active “PypeIt Users” Slack workspace. We periodically update the invitation here.

Below are some useful tools and instruments that I am frequently using:
