Context. GRB 211106A and 211227A are two recent gamma-ray bursts (GRBs) whose initial X-ray position enabled us to possibly associate them with bright, low-redshift galaxies ( z < 0.7). The prompt emission properties suggest that is a genuine short-duration short extended emission. Therefore, they likely be produced by compact binary merger. However, classification based solely on the can misleading. Aims. possibility of having GRBs occurring in local Universe makes ideal targets for...

Context: GRB 211106A and 211227A are recent gamma-ray bursts (GRBs) with initial X-ray positions suggesting associations nearby galaxies (z < 0.7). Their prompt emission characteristics indicate is a short-duration short extended emission, likely originating from compact binary mergers. However, classifying solely based on can be misleading. Aims: These GRBs in the local Universe offer opportunities to search for associated kilonova (KN) study host galaxy properties detail. Methods: We...
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...
SVOM is a Sino-French space mission targeting high-energy transient astrophysical objects such as gamma-ray bursts. The soft X-ray part of the spectrum covered by Micro-channel Telescope (MXT) which narrow field telescope designed to precisely localize sources. This paper presents method implemented on-board characterize and sources with MXT. A specific localization was developed accommodate optical system MXT, based on "Lobster-Eye" grazing incidence micro-pore optics. For first time,...
