Oxygen and iron in interstellar dust: an X-ray investigation
I. Psaradaki, E. Costantini, D. Rogantini +9
Understanding the chemistry of the interstellar medium (ISM) is fundamental for the comprehension of the Galactic and stellar evolution. X-rays provide an excellent way to study th…
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…
Demonstration of MHz frequency domain multiplexing readout of 37 transition edge sensors for high-resolution x-ray imaging spectrometers
H. Akamatsu, D. Vaccaro, L. Gottardi +22
We report on the development and demonstration of a MHz frequency domain multiplexing (FDM) technology to read out arrays of cryogenic transition edge sensor (TES) X-ray microcalor…
Single pixel performance of a 3232 Ti/Au TES array with broadband X-ray spectra
Matteo D'Andrea, Emanuele Taralli, Hiroki Akamatsu +10
We are developing a kilo-pixels Ti/Au TES array as a backup option for Athena X-IFU. Here we report on single-pixel performance of a 3232 array operated in a Frequency Divi…
Interstellar oxygen along the line of sight of Cygnus X-2
I. Psaradaki, E. Costantini, M. Mehdipour +7
Interstellar dust permeates our Galaxy and plays an important role in many physical processes in the diffuse and dense regions of the interstellar medium. High-resolution X-ray spe…
Progress in the development of frequency domain multiplexing for the X-ray Integral Field Unit on board the Athena mission
H. Akamatsu, L. Gottardi, J. van der Kuur +11
Frequency domain multiplexing (FDM) is the baseline readout system for the X-ray Integral Field Unit (X-IFU) on board the Athena mission. Under the FDM scheme, TESs are coupled to…
