Quasars observed during the epoch of reionization offer insight into cosmology, galaxy evolution, and black hole growth at early cosmological times.
This project is a multiwavelength redshift survey with observations of 25 quasars at z>6.5.
A 280 sq. arcmin survey of 25 quasars with JWST NIRCam imaging and wide-field slitless spectroscopy to:
☞ Map the large scale environment and host dark matter halos of the earliest supermassive black holes;
☞ Investigate the co-evolution of supermassive black holes and their host galaxies;
☞ Constrain black hole growth and AGN feedback;
☞ Probe Galaxy Ionizing Photon Escape and Cosmic Reionization
A 33 sq. arcmin survey of 25 quasars with ALMA Band 6 mosaic imaging and spectroscopy to:
☞ Map protocluster-scale environments of quasar fields rich with dusty star-forming galaxies;
☞ Constrain which galaxies dominate the cosmic infrared background;
☞ Measure the [CII] luminosity function;
☞ Probe metal enrichment and galaxy formation with co-spatial quasar absorption lines
Deep optical photometry and spectroscopy
We are performing deep optical imaging for all ASPIRE quasar fields with HST, Keck, LBT and Magellan and obtaining spectroscopic follow up with Keck, MMT and Magellan.
VLA radio observations
We obtained deep 3GHz radio observations for all ASPIRE quasar fields to detect the radio emissions from the quasars and distant galaxies in these fields.
Chandra X-ray observations
We are collecting deep X-ray images for ASPIRE quasars. These data will enable us to characterize the quasar accretion physics and AGN activities in field galaxies.
