The Future of Gamma-Ray Bursts as Probes of the Epoch of Reionization in the Era of JWST and the Extremely Large Telescope
H. M. Fausey, A. J. van der Horst, N. R. Tanvir +1
The Epoch of Reionization (EoR) is a key era of cosmological history that remains poorly understood. An examination of the Ly-alpha damping wing of high-redshift GRBs can provide d…
A Proliferated Space Architecture for Time-Domain Astrophysics
Daniel Kocevski, Eric Burns, Thomas Barclay +58
Time-Domain and Multi-Messenger Astrophysics (TDAMM) is entering a discovery-rich but follow-up-limited era, creating an urgent need for responsive, multiwavelength space-based cap…
The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision
G. E. Anderson, G. P. Lamb, B. P. Gompertz +64
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…
JWST reveals a supernova following a gamma-ray burst at z 7.3
A. J. Levan, B. Schneider, E. Le Floc'h +50
The majority of energetic long-duration gamma-ray bursts (GRBs) are thought to arise from the collapse of massive stars, making them powerful tracers of star formation across cosmi…
SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization
B. Cordier, J. Y. Wei, N. R. Tanvir +103
Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…
Revisiting the Intergalactic Medium Around GRB 130606A and Constraints on the Epoch of Reionization
H. M. Fausey, A. J. van der Horst, N. R. Tanvir +4
Gamma-ray bursts (GRBs) are excellent probes of the high-redshift Universe due to their high luminosities and the relatively simple intrinsic spectra of their afterglows. They can…
Neutral Fraction of Hydrogen in the Intergalactic Medium Surrounding High-Redshift Gamma-Ray Burst 210905A
H. M. Fausey, S. Vejlgaard, A. J. van der Horst +22
The Epoch of Reionization (EoR) is a key period of cosmological history in which the intergalactic medium (IGM) underwent a major phase change from being neutral to almost complete…
Fires in the deep: The luminosity distribution of early-time gamma-ray-burst afterglows in light of the Gamow Explorer sensitivity requirements
D. A. Kann, N. E. White, G. Ghirlanda +58
Gamma-ray bursts (GRBs) are ideal probes of the Universe at high redshift (z > 5), pinpointing the locations of the earliest star-forming galaxies and providing bright backlights t…
Photometric Redshift Estimation for Gamma-Ray Bursts from the Early Universe
H. M. Fausey, A. J. van der Horst, N. E. White +16
Future detection of high-redshift gamma-ray bursts (GRBs) will be an important tool for studying the early Universe. Fast and accurate redshift estimation for detected GRBs is key…
Dissecting the interstellar medium of a z=6.3 galaxy: X-shooter spectroscopy and HST imaging of the afterglow and environment of the Swift GRB 210905A
A. Saccardi, S. D. Vergani, A. De Cia +35
The study of the properties of galaxies in the first billion years after the Big Bang is one of the major topic of current astrophysics. Optical/near-infrared spectroscopy of the a…
Rapid radio brightening of GRB 210702A
G. E. Anderson, T. D. Russell, H. M. Fausey +16
We observed the rapid radio brightening of GRB 210702A with the Australian Telescope Compact Array (ATCA) just 11hr post-burst, tracking early-time radio variability over a 5hr per…
A blast from the infant Universe: the very high-z GRB 210905A
A. Rossi, D. D. Frederiks, D. A. Kann +52
We present a detailed follow-up of the very energetic GRB 210905A at a high redshift of z = 6.312 and its luminous X-ray and optical afterglow. We obtained a photometric and spectr…
The Photo-z Infrared Telescope (PIRT) -- a space instrument for rapid follow up of high-redshift gamma-ray bursts and electromagnetic counterparts to gravitational wave events
M. Seiffert, A. Balady, T. -C. Chang +17
The Photo-z InfraRed Telescope (PIRT) is an instrument on the Gamow Explorer, currently proposed for a NASA Astrophysics Medium Explorer. PIRT works in tandem with a companion wide…
A Gaussian Process Regression Reveals No Evidence for Planets Orbiting Kapteyn's Star
Anna Bortle, Hallie Fausey, Jinbiao Ji +3
Radial-velocity (RV) planet searches are often polluted by signals caused by gas motion at the star's surface. Stellar activity can mimic or mask changes in the RVs caused by orbit…
Magnetic Fields on the Flare Star Trappist-1: Consequences for Radius Inflation and Planetary Habitability
D. J. Mullan, J. MacDonald, S. Dieterich +1
We construct evolutionary models of Trappist-1 in which magnetic fields impede the onset of convection according to a physics-based criterion. In the models that best fit all obser…
