The 2023 Flight of the Faint Intergalactic-medium Redshifted Emission Balloon

The Astrophysical Journal Supplement Series
The second iteration of the Faint Intergalactic-medium Redshifted Emission Balloon (FIREBall-2) is a UV multiobject spectrograph designed to detect emission from the circumgalactic and circumquasar medium at low redshifts ( z < 1).

Cosmic Reionization on Computers: Statistics, Physical Properties, and Environments of Lyman Limit Systems at z ∼ 6

The Astrophysical Journal
Lyman limit systems (LLSs) are dense hydrogen clouds with high enough H i column densities to absorb Lyman continuum photons emitted from distant quasars.

Quasar Radiative Feedback May Suppress Galaxy Growth on Intergalactic Scales at z = 6.3

The Astrophysical Journal Letters
We present observational evidence that intense ionizing radiation from a luminous quasar suppresses nebular emission in nearby galaxies on intergalactic scales at z = 6.3.

The Quasar Proximity Effect as an Alternative Probe of Quasar Pair Distances

The Astrophysical Journal Letters
Recently discovered quasar pairs at high redshifts ( z  ≳ 5) are likely precursors to supermassive black hole mergers, providing a promising window to high-redshift quasar growth mechanisms.

Probing the He ii Reionization ERA via Absorbing C iv Historical Yield (HIERACHY). III. The C iv Absorber Catalog and Initial Results on Cosmic Abundance Evolution at z ≈ 3–5

The Astrophysical Journal
As part of the HIERACHY program, we collect the high signal-to-noise ratio and high-spectral resolution optical spectra of 25 quasars at z  ≈ 4–5 to constrain the C iv evolution at z  ≈ 3–5.
