Science with a small two-band UV-photometry mission III: Active Galactic Nuclei and nuclear transients
M. Zajaček, B. Czerny, V. K. Jaiswal +14
In this review (the third in the series focused on a small two-band UV-photometry mission), we assess possibilities for a small UV two-band photometry mission in studying accreting…
Science with a small two-band UV-photometry mission I: Mission description and follow-up observations of stellar transients
N. Werner, J. Řípa, C. Thöne +33
This is the first in a collection of three papers introducing the science with an ultra-violet (UV) space telescope on an approximately 130~kg small satellite with a moderately fas…
CAvity DEtection Tool (CADET): Pipeline for automatic detection of X-ray cavities in hot galactic and cluster atmospheres
Tomáš Plšek, Norbert Werner, Martin Topinka +1
The study of jet-inflated X-ray cavities provides a powerful insight into the energetics of hot galactic atmospheres and radio-mechanical AGN feedback. By estimating the volumes of…
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…
Chandra measurements of gas homogeneity and turbulence at intermediate radii in the Perseus Cluster
Martijn de Vries, Adam B. Mantz, Steven W. Allen +6
We present a Chandra study of surface brightness fluctuations in the diffuse intracluster medium of the Perseus Cluster. Our study utilizes deep, archival imaging of the cluster co…
A multifrequency characterization of the extragalactic hard X-ray sky
Matej Kosiba, Harold Andres Peña-Herazo, Francesco Massaro +5
Nowadays we know that the origin of the Cosmic X-ray Background (CXB) is due to the integrated emission of nearby active galactic nuclei. Thus, to obtain a precise estimate of the…
