Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history early universe, but their detection remains rare. Here we report a GRB triggered in 0.5--4 keV band by Wide-field X-ray Telescope (WXT) on board Einstein Probe (EP) mission, designated as EP240315a, whose bright peak was also detected Swift Burst Alert Konus-Wind through off-line analyses. At redshift $z=4.859$, EP240315a showed...
The space-based multi-band astronomical variable objects monitor (SVOM) is a Chinese–French mission due to be launched in 2023. It composed of four space borne instruments: ECLAIRs, for detecting x-ray and gamma-ray transients; GRM, spectrometer; VT, visible telescope the Microchannel X-ray Telescope (MXT). MXT's main goal precisely localize, spectrally characterize afterglows bursts. MXT narrow-field-optimised lobster eye focusing comprising an array 25 square micro pore optics (MPOs), with...
SVOM (space-based multi-band astronomical variable objects monitor) is a mission developed within Sino-French cooperation context and dedicated to the detection, localization study of gamma ray bursts (GRBs) other high-energy transient phenomena. Four instruments, operating in different wavelengths, are implemented on board order perform GRB detection observations. The MXT instrument, by National French Space Agency (CNES) collaboration with CEA, MPE, IJCLab University Leicester, observation...
The Microchannel X-Ray Telescope (MXT) is part of the Sino French SVOM mission mainly dedicated to Gamma-Ray Bursts (GRBs). MXT combines a "lobster-eye" focusing X-ray micro-pore optic with pnCCD detector operating from 0.1 10 keV. A stable structure made carbon fiber reinforced polymer (CFRP) and titanium connects two parts provides interfaces satellite. After short description instrument, this paper first presents alignment process measurement line sight (LOS) at MPEs PANTER facility in...
We present a look at Ookami, project providing community access to testbed supercomputer with the ARM-based A64FX processors developed by collaboration between RIKEN and Fujitsu deployed in Japanese Fugaku. describe project, provide details about user base education/training program, highlights from performance studies of two astrophysical simulation codes.
Abstract The Microchannel X-ray Telescope (MXT) will be the first focusing telescope based on a "Lobster-Eye" optical design to flown Sino-French mission SVOM. SVOM dedicated study of Gamma-Ray Bursts and more generally time-domain astrophysics. MXT is compact (focal length ∼ 1.15 m) light (< 42 kg) instrument, sensitive in 0.2–10 keV energy range. It composed an system, micro-pore optics (MPOs) 40 µm pore size, coupled low-noise pnCDD detector. In this paper we describe expected...
