The Complete Catalog of Gamma-Ray Transients Observed by GRBAlpha & VZLUSAT-2 CubeSat Missions

Marianna Dafcikova, Jakub Ripa, Andras Pal +45

We present the largest sample of gamma-ray transients observed by any CubeSat mission so far. Observations were acquired by a 1U CubeSat GRBAlpha, the smallest astrophysical space…

X-ray line diagnostics of the multi-phase gas in the Centaurus cluster core with XRISM/Resolve

Marie Kondo, Kotaro Fukushima, Kazunori Suda +18

We report the multi-temperature structure of the intracluster medium (ICM) in the Centaurus cluster core observed with XRISM/Resolve. Thanks to its high energy resolution, Resolve…

GRBAlpha, VZLUSAT-2 and GRBBeta -- GRB observations with CubeSats

Jakub Ripa, Marianna Dafcikova, Andras Pal +49

Results from GRBAlpha, VZLUSAT-2 and GRBBeta CubeSats and their on-board gamma-ray detectors for monitoring transients are summarised in this article. GRBAlpha was a 1U CubeSat lau…

XRISM constraints on unidentified X-ray emission lines, including the 3.5 keV line, in the stacked spectrum of ten galaxy clusters

XRISM Collaboration, Marc Audard, Hisamitsu Awaki +150

We stack 3.75 Megaseconds of early XRISM Resolve observations of ten galaxy clusters to search for unidentified spectral lines in the 2.5-15 keV band (rest frame), including t…

The thermodynamic structure and large-scale structure filament in MACS J0717.5+3745

J. P. Breuer, N. Werner, T. Plšek +12

We present the results of Chandra and XMM-Newton X-ray imaging and spatially resolved spectroscopy, as well as new MUSTANG2 90 GHz observations of the thermal Sunyaev-Zeldovich eff…

The infalling elliptical galaxy M89: The chemical composition of the AGN disturbed hot atmosphere

Sinancan Kara, Tomáš Plšek, Klaudia Protušová +4

The chemical enrichment of X-ray-emitting hot atmospheres has hitherto been primarily studied in galaxy clusters. These studies revealed relative abundances of heavy elements that…

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…
