IR and Optical Observations of GRB 030115
Allyn Dullighan, George Ricker, Nathaniel Butler +1
We present an upper limit on the brightness of the afterglow of the long GRB 030115 measured from Infrared (IR) images taken with the Magellan Classic Cam instrument of Ks > 22 at…
Zeta functions and topology of Heisenberg cycles for linear ergodic flows
Nathaniel Butler, Heath Emerson, Tyler Schulz
Placing a Dirac-Schrödinger operator along the orbit of a flow on a compact manifold \(M\) defines an \(\R\)-equivariant spectral triple over the algebra of smooth functions on \(…
ALMA and RATIR observations of GRB131030A
Kuiyun Huang, Yuji Urata, Satoko Takahashi +22
We report on the first open-use based Atacama Large Millimeter/submm Array (ALMA) 345-GHz observation for the late afterglow phase of GRB131030A. The ALMA observation constrained a…
GRB Energetics in the Swift Era
Daniel Kocevski, Nathaniel Butler
We examine the rest frame energetics of 76 gamma-ray bursts (GRBs) with known redshift that were detected by the Swift spacecraft and monitored by the satellite's X-ray Telescope (…
CAGIRE: a wide-field NIR imager for the COLIBRI 1.3 meter robotic telescope
Alix Nouvel de la Flèche, Jean-Luc Atteia, Jérémie Boy +32
The use of high energy transients such as Gamma Ray Bursts (GRBs) as probes of the distant universe relies on the close collaboration between space and ground facilities. In this c…
Short-Duration Gamma-ray Burst and Afterglow Rates in the Rubin and Roman Era
Tzvetelina Dimitrova, Nathaniel Butler
The paper models the expected detection rates of short gamma‑ray burst afterglows, including orphan afterglows, with the Vera C. Rubin Observatory (LSST) and the Roman Space Telesc…
Pulse Width Evolution of Late Time X-rays Flares in GRBs: Evidence For Internal Shocks
Daniel Kocevski, Nathaniel Butler, Joshua S. Bloom
We study the duration and variability of late time X-ray flares following gamma-ray bursts (GRBs) observed by the narrow field X-ray telescope (XRT) aboard the {\it Swift} spacecra…
Flux reconstruction for the NIR camera CAGIRE at the focus of the Colibrà telescope
Alix Nouvel de la Flèche, Jean-Luc Atteia, Hervé Valentin +20
CAGIRE is the near infrared camera of the Colibrà robotic telescope, designed for the follow-up of SVOM alerts. It is based on the ALFA 2k x 2k detector, from the LYNRED French Co…
The TESS Objects of Interest Catalog from the TESS Prime Mission
Natalia M. Guerrero, S. Seager, Chelsea X. Huang +102
We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the…
First Results from the rapid-response spectrophotometric characterization of Near-Earth Objects
Samuel Navarro-Meza, Michael Mommert, David Trilling +6
As part of our multi-observatory, multi-filter campaign, we present \rmi color observations of 82 Near-Earth Objects (NEOs) obtained with the RATIR instrument on the 1.5m robotic t…
The EXoplanet Climate Infrared TElescope (EXCITE): A balloon-borne mission to measure spectroscopic phase curves of transiting hot Jupiters
Timothy D. Rehm, Caitlyn Altermatt, Lee Bernard +26
The EXoplanet Climate Infrared TElescope (EXCITE) is a balloon-borne mission dedicated to measuring spectroscopic phase curves of hot Jupiter-type exoplanets. Phase curve measureme…
On the local convergence of integer-valued Lipschitz functions on regular trees
Nathaniel Butler, Kesav Krishnan, Gourab Ray +1
We study random integer-valued Lipschitz functions on regular trees. It was shown by Peled, Samotij and Yehudayoff that such functions are localized, however, finer questions about…
Evidence for a Bright-Edged Jet in the Optical/NIR Afterglow of GRB 160625B
Robert Strausbaugh, Nathaniel Butler, William H. Lee +2
Using deep and high-cadence gamma-ray burst (GRB) afterglow data from RATIR, we observe a sharp and achromatic light curve break 12.6 days after the GRB, accompanied by an approxim…
Improved Standardization of Type II-P Supernovae: Application to an Expanded Sample
Dovi Poznanski, Nathaniel Butler, Alexei V. Filippenko +16
In the epoch of precise and accurate cosmology, cross-confirmation using a variety of cosmographic methods is paramount to circumvent systematic uncertainties. Owing to progenitor…
