White Dwarf-Black Hole Binary Progenitors of Low Redshift Gamma-ray Bursts
Nicole M. Lloyd-Ronning, Jarrett L. Johnson, Phoebe R. Upton Sanderbeck +2
Although there is strong evidence that many long GRBs are associated with the collapse of a massive star, tantalizing results in recent years have upended the direct association of…
On the Anti-Correlation between Duration and Redshift in Gamma-ray Bursts
Nicole M. Lloyd-Ronning, Jarrett L. Johnson, Roseanne M. Cheng +4
For gamma-ray bursts (GRBs) with durations greater than two seconds (so-called long GRBs), the intrinsic prompt gamma-ray emission appears, on average, to last longer for bursts at…
Properties of High-Redshift GRBs
Chris L. Fryer, Amy Y. Lien, Andrew Fruchter +5
The immense power of gamma-ray bursts (GRBs) make them ideal probes of the early universe. By using absorption lines in the afterglows of high-redshift GRBs, astronomers can study…
Nucleosynthetic signatures of primordial origin around supermassive black holes
Phoebe Upton Sanderbeck, Simeon Bird, Zoltan Haiman
If primordial black holes (PBHs) seeded the supermassive black holes (SMBHs) at the centers of high-redshift quasars, then the gas surrounding these black holes may reveal nucleosy…
Forecasts for Broadband Intensity Mapping of the Ultraviolet-Optical Background with CASTOR and SPHEREx
Bryan Scott, Phoebe Upton Sanderbeck, Simeon Bird
Broadband tomography statistically extracts the redshift distribution of frequency dependent emission from the cross correlation of intensity maps with a reference catalog of galax…
Effect of Separate Initial Conditions on the Lyman- Forest in Simulations
M. A. Fernandez, Simeon Bird, Phoebe Upton Sanderbeck
Using a set of high resolution simulations, we quantify the effect of species specific initial transfer functions on probes of the IGM via the Lyman- forest. We focus on redshif…
Conditions for Reionizing the Universe with A Low Galaxy Ionizing Photon Escape Fraction
Steven L. Finkelstein, Anson D'Aloisio, Jan-Pieter Paardekooper +7
We explore scenarios for reionizing the intergalactic medium with low galaxy ionizing photon escape fractions. We combine simulation-based halo-mass dependent escape fractions with…
Radio Interferometric Planet Search II: Constraints on sub-Jupiter-Mass Companions to GJ 896A
Geoffrey C. Bower, Alberto Bolatto, Eric B. Ford +5
We present results from the Radio Interferometric Planet (RIPL) search for compan- ions to the nearby star GJ 896A. We present 11 observations over 4.9 years. Fitting astrometric p…
