GRBAlpha: the smallest astrophysical space observatory -- Part 1: Detector design, system description and satellite operations
András Pál, Masanori Ohno, László Mészáros +42
Aims. Since launched on 2021 March 22, the 1U-sized CubeSat GRBAlpha operates and collects scientific data on high-energy transients, making it the smallest astrophysical space obs…
The peak-flux of GRB 221009A measured with GRBAlpha
Jakub Ripa, Hiromitsu Takahashi, Yasushi Fukazawa +42
The brightest gamma-ray burst ever observed, long-duration GRB 221009A, was detected by GRBAlpha nano-satellite without saturation. We present light curves of the prompt emission i…
Early results from GRBAlpha and VZLUSAT-2
Jakub Ripa, Andras Pal, Masanori Ohno +37
We present the detector performance and early science results from GRBAlpha, a 1U CubeSat mission, which is a technological pathfinder to a future constellation of nanosatellites m…
High energy emission component, population, and contribution to the extragalactic gamma-ray background of gamma-ray emitting radio galaxies
Yasushi Fukazawa, Hiroto Matake, Taishu Kayanoki +2
In this study, we systematically studied the X-ray to GeV gamma-ray spectra of 61 {\it Fermi} Large Area Telescope (LAT) detected radio galaxies. We found an anticorrelation betwee…
Catalog of Long-Term Transient Sources in the First 10 Years of Fermi-LAT Data
L. Baldini, J. Ballet, D. Bastieri +112
We present the first Fermi Large Area Telescope (LAT) catalog of long-term -ray transient sources (1FLT). This comprises sources that were detected on monthly time intervals dur…
The simulation framework of the timing-based localization for future all-sky gamma-ray observations with a fleet of Cubesats
Masanori Ohno, Norbert Werner, Andras Pal +22
The timing-based localization, which utilize the triangulation principle with the different arrival time of gamma-ray photons, with a fleet of Cubesats is a unique and powerful sol…
GRBAlpha: A 1U CubeSat mission for validating timing-based gamma-ray burst localization
András Pál, Masanori Ohno, László Mészáros +26
GRBAlpha is a 1U CubeSat mission with an expected launch date in the first half of 2021. It carries a 75 x 75 x 5 mm CsI(Tl) scintillator, read out by a dual-channel multi-pixel ph…
XL-Calibur -- a second-generation balloon-borne hard X-ray polarimetry mission
Q. Abarr, H. Awaki, M. G. Baring +38
XL-Calibur is a hard X-ray (15-80 keV) polarimetry mission operating from a stabilised balloon-borne platform in the stratosphere. It builds on heritage from the X-Calibur mission,…
