Magnetic fields and relativistic electrons fill entire galaxy cluster
A. Botteon, R. J. van Weeren, G. Brunetti +12
The hot plasma within merging galaxy clusters is predicted to be filled with shocks and turbulence that may convert part of their kinetic energy into relativistic electrons and mag…
Line Emission Mapper (LEM): Probing the physics of cosmic ecosystems
Ralph Kraft, Maxim Markevitch, Caroline Kilbourne +107
The Line Emission Mapper (LEM) is an X-ray Probe for the 2030s that will answer the outstanding questions of the Universe's structure formation. It will also provide transformative…
The Planck clusters in the LOFAR sky. III. LoTSS-DR2: Dynamic states and density fluctuations of the intracluster medium
X. Zhang, A. Simionescu, F. Gastaldello +19
The footprint of LoTSS-DR2 covers 309 PSZ2 galaxy clusters, 83 of which host a radio halo and 26 host a radio relic(s). It provides us an excellent opportunity to statistically stu…
Frequency domain multiplexing readout for large arrays of transition-edge sensors
Davide Vaccaro, Hiroki Akamatsu, Luciano Gottardi +13
We report our most recent progress and demonstration of a frequency domain multiplexing (FDM) readout technology for transition-edge sensor (TES) arrays, both of which we have been…
Performance of the SRON Ti/Au Transition Edge Sensor X-ray Calorimeters
Martin de Wit, Luciano Gottardi, Kenichiro Nagayoshi +7
In the early 2030s, ESAs new X-ray observatory, Athena, is scheduled to be launched. It will carry two main instruments, one of which is the X-ray Integral Field Unit (X-IFU), an X…
Susceptibility study of TES micro-calorimeters for X-ray spectroscopy under FDM readout
Davide Vaccaro, Hiroki Akamatsu, Luciano Gottardi +15
We present a characterization of the sensitivity of TES X-ray micro-calorimeters to environmental conditions under frequency-domain multiplexing (FDM) readout. In the FDM scheme, e…
Mitigation of the Magnetic Field Susceptibility of Transition Edge Sensors using a Superconducting Groundplane
Martin de Wit, Luciano Gottardi, Marcel L. Ridder +7
Transition edge sensor (TES) microcalorimeters and bolometers are used for a variety of applications. The sensors are based on the steep temperature-dependent resistance of the nor…
The Athena X-ray Integral Field Unit: a consolidated design for the system requirement review of the preliminary definition phase
Didier Barret, Vincent Albouys, Jan-Willem den Herder +296
The Athena X-ray Integral Unit (X-IFU) is the high resolution X-ray spectrometer, studied since 2015 for flying in the mid-30s on the Athena space X-ray Observatory, a versatile ob…
Diffuse radio source candidate in CIZA J1358.9-4750
Kohei Kurahara, Takuya Akahori, Ruta Kale +11
We report on results of our upgraded Giant Metrewave Radio Telescope (uGMRT) observations for an early-stage merging galaxy cluster, CIZA J1358.9-4750 (CIZA1359), in Band-3 (300--5…
X-ray spectra of the Fe-L complex III: systematic uncertainties in the atomic data
Liyi Gu, Chintan Shah, Junjie Mao +14
There has been a growing request from the X-ray astronomy community for a quantitative estimate of systematic uncertainties originating from the atomic data used in plasma codes. T…
The NuSTAR and Chandra view of CL 0217+70 and Its Tell-Tale Radio Halo
Ayşegül Tümer, Daniel R. Wik, Xiaoyuan Zhang +11
Mergers of galaxy clusters are the most energetic events in the universe, driving shock and cold fronts, generating turbulence, and accelerating particles that create radio halos a…
The Planck clusters in the LOFAR sky. I. LoTSS-DR2: new detections and sample overview
A. Botteon, T. W. Shimwell, R. Cassano +23
Relativistic electrons and magnetic fields permeate the intra-cluster medium (ICM) and manifest themselves as diffuse sources of synchrotron emission observable at radio wavelength…
Spectral study of the diffuse synchrotron source in the galaxy cluster Abell 523
Valentina Vacca, Timothy Shimwell, Richard A. Perley +26
The galaxy cluster Abell 523 (A523) hosts an extended diffuse synchrotron source historically classified as a radio halo. Its radio power at 1.4 GHz makes it one of the most signif…
