Deep Learning of Quasar Spectra to Discover and Characterize Damped Lya Systems
David Parks, J. Xavier Prochaska, Shawfeng Dong +1
We have designed, developed, and applied a convolutional neural network (CNN) architecture using multi-task learning to search for and characterize strong HI Lya absorption in quas…
Correcting CIV-Based Virial Black Hole Masses
Liam Coatman, Paul C. Hewett, Manda Banerji +3
The CIV broad emission line is visible in optical spectra to redshifts exceeding z~5. CIV has long been known to exhibit significant displacements to the blue and these `blueshifts…
Detailed Design of a Deployable Tertiary Mirror for the Keck I Telescope
J. Xavier Prochaska, Chris Ratliff, Jerry Cabak +16
Motivated by the ever increasing pursuit of science with the transient sky (dubbed Time Domain Astronomy or TDA), we are fabricating and will commission a new deployable tertiary m…
MUSE searches for galaxies near very metal-poor gas clouds at z~3: new constraints for cold accretion models
Michele Fumagalli, Sebastiano Cantalupo, Avishai Dekel +4
We report on the search for galaxies in the proximity of two very metal-poor gas clouds at z~3 towards the quasar Q0956+122. With a 5-hour MUSE integration in a ~500x500 kpc^2 regi…
