Probing Inhomogeneity in the Helium Ionizing UV Background
Sean Morrison, Matthew M. Pieri, David Syphers +1
We present an analysis combining the simultaneous measurement of intergalactic absorption by hydrogen (H I), helium (He II) and oxygen (O VI) in UV and optical quasar spectra. The…
Spectroscopic QUasar Extractor and redshift (z) EstimatorSQUEzE I: Methodology
Ignasi Pérez-Ràfols, Matthew M. Pieri, Michael Blomqvist +2
We present SQUEzE, a software package to classify quasar spectra and estimate their redshifts. SQUEzE is a random forest classifier operating on the parameters of candidate emissio…
Early metal enrichment of gas-rich galaxies at z~5
Suraj Poudel, Varsha P. Kulkarni, Sean Morrison +4
We present abundance measurements of elements O, C, Si and Fe for three gas-rich galaxies at z~5 using observations from the Very Large Telescope (VLT) and the Keck telescope in or…
