Predictions for Short Gamma-Ray Burst Detections by COSI
Eliza Neights, Eric Burns, Nicolò Parmiggiani +21
The Compton Spectrometer and Imager (COSI) is a soft gamma-ray telescope scheduled to launch in 2027. COSI will trigger onboard the spacecraft in response to short-duration transie…
Imaging and Spectral Fitting of Bright Gamma-ray Sources with the COSI Balloon Payload
Jarred M. Roberts, Steven Boggs, Thomas Siegert +17
The Compton Spectrometer and Imager balloon payload (COSI-Balloon) is a wide-field-of-view Compton -ray telescope that operates in the 0.2 - 5 MeV bandpass. COSI-Balloon had a s…
The Compton Spectrometer and Imager
John A. Tomsick, Steven E. Boggs, Andreas Zoglauer +72
The Compton Spectrometer and Imager (COSI) is a NASA Small Explorer (SMEX) satellite mission in development with a planned launch in 2027. COSI is a wide-field gamma-ray telescope…
The cosipy library: COSI's high-level analysis software
Israel Martinez-Castellanos, Savitri Gallego, Chien-You Huang +72
The Compton Spectrometer and Imager (COSI) is a selected Small Explorer (SMEX) mission launching in 2027. It consists of a large field-of-view Compton telescope that will probe wit…
The long-stable hard state of XTE J1752-223 and the disk truncation dilemma
Riley M. T. Connors, Javier A. Garcia, John Tomsick +10
The degree to which the thin accretion disks of black hole X-ray binaries are truncated during hard spectral states remains a contentious open question in black hole astrophysics.…
Soft gamma-ray polarimetry with COSI using maximum likelihood analysis
John A. Tomsick, Alexander Lowell, Hadar Lazar +2
Measurements of the linear polarization of high-energy emission from pulsars, accreting black holes, and gamma-ray bursts (GRBs) provide an opportunity for constraining the emissio…
Measurement of Galactic Al with the Compton Spectrometer and Imager
Jacqueline Beechert, Thomas Siegert, John A. Tomsick +11
The Compton Spectrometer and Imager (COSI) is a balloon-borne compact Compton telescope designed to survey the 0.2-5 MeV sky. COSI's energy resolution of 0.2% at 1.8 MeV, sin…
Spectral and Timing Analysis of NuSTAR and Swift/XRT Observations of the X-Ray Transient MAXI J0637-430
Hadar Lazar, John A. Tomsick, Sean N. Pike +10
We present results for the first observed outburst from the transient X-ray binary source MAXI J0637-430. This study is based on eight observations from the Nuclear Spectroscopic T…
Imaging the 511 keV positron annihilation sky with COSI
Thomas Siegert, Steven E. Boggs, John A. Tomsick +10
The balloon-borne Compton Spectrometer and Imager (COSI) had a successful 46-day flight in 2016. The instrument is sensitive to photons in the energy range - MeV. Compton t…
Detection of the 511 keV Galactic positron annihilation line with COSI
Carolyn A. Kierans, Steven E. Boggs, Andreas Zoglauer +10
The signature of positron annihilation, namely the 511 keV -ray line, was first detected coming from the direction of the Galactic center in the 1970's, but the source of Galact…
