With the Swift detection of GRB090423 at z = 8.2, it was confirmed that GRBs are now detectable at (significantly) larger redshifts than AGN, and so can indeed be used as probes of the Early Universe. The Energetic X‐ray Imaging Survey Telescope (EXIST) mission has been designed to detect and promptly measure redshifts and both soft X‐ray (0.1–10 keV) and simultaneous nUV‐nIR (0.3–2.3 microns) imaging and spectra for GRBs out to redshifts z∼18, which encompasses (or even exceeds) current…

Overview of EXIST mission science and implementation
The Energetic X-ray Imaging Survey Telescope (EXIST) is designed to i) use the birth of stellar mass black holes, as revealed by cosmic Gamma-Ray Bursts (GRBs), as probes of the very first stars and
Epoch of Reionization Energetic X-ray Survey ( EREXS ) to measure the birth and growth of the first Black Holes
The Epoch of Reionization Energetic X-ray Survey (EREXS) is designed to i) use the birth of stellar mass black holes, as revealed by cosmic Gamma-Ray Bursts (GRBs), as probes of the first stars and
Gamma-ray bursts as cosmological probes: ΛCDM vs. conformal gravity
ΛCDM, for the currently preferred cosmological density Ω0 and cosmological constant ΩΛ, predicts that the Universe expansion decelerates from early times to redshift z ≈ 0.9 and accelerates at later


GRB 090423 at a redshift of z ≈ 8.1
Observations of GRB 090423 and the near-infrared spectroscopic measurement of its redshift are reported, suggesting that the mechanisms and progenitors that gave rise to this burst about 600,000,000 years after the Big Bang are not markedly different from those producing GRBs about 10, thousands of years later.
GRB Probes of the High‐z Universe with EXIST
The Energetic X‐ray Imaging Survey Telescope (EXIST) mission concept was selected for further study under the Astrophysics Strategic Mission Concept Study (ASMCS) program. The mission design is
Revealing the First Stellar and Supermassive Black Holes to EXIST
The epochs of origin of the first stars and galaxies, and subsequent growth of the first supermassive black holes, are among the most fundamental questions. Observations of the highest redshift
A glimpse of the end of the dark ages: the gamma-ray burst of 23 April 2009 at redshift 8.3
It is thought that the first generations of massive stars in the Universe were an important, and quite possibly dominant, source of the ultra-violet radiation that reionized the hydrogen gas in the
Chasing the heaviest black holes of jetted active galactic nuclei
We investigate the physical properties of 10 blazars at redshift greater than 2 detected in the 3-yr all-sky survey performed by the Burst Alert Telescope (BAT) on board the Swift satellite. We find
Simulating high‐redshift galaxies
Recent observations have gathered a considerable sample of high-redshift galaxy candidates and determined the evolution of their luminosity function (LF). To interpret these findings, we use
In Situ Probes of the First Galaxies and Reionization: Gamma-ray Bursts
The first structures in the Universe formed at z>7, at higher redshift than all currently known galaxies. Since GRBs are brighter than other cosmological sources at high redshift and exhibit simple
The high energy telescope on EXIST
The Energetic X-ray Imaging Survey Telescope (EXIST) is a proposed next generation multi-wavelength survey mission. The primary instrument is a High Energy telescope (HET) that conducts the deepest
Lyα emission lines should be attenuated in a neutral intergalactic medium. Therefore, the visibility of Lyα emitters at high redshifts can serve as a valuable probe of reionization at about the 50%

We identify 73 z~7 and 59 z~8 candidate galaxies in the reionization epoch, and use this large 26-29.4 AB mag sample of galaxies to derive very deep luminosity functions to <-18 AB mag and the star
