The soft X-ray band below keV is expected to provide rich information on metallicity,
temperature, and distribution of hot gas in our galaxy and the intergalactic medium …

For future X-ray astrophysics missions, X-ray microcalorimeters can be optimized with
different properties in different regions of the focal plane. This approach has the potential to …

X-ray microcalorimeters using transition-edge sensors (TES) show great promise for use in

In many superconducting transition-edge sensor (TES) microcalorimeters, the measured
electrical noise exceeds theoretical estimates based on a thermal model of a single body …

We are developing cryogenic high-resolution X-ray, Gamma-ray and neutron spectrometers
based on superconducting Mo/Cu transition edge sensors. Here we discuss the sensor …

We measured noise in a variety of Mo/Au transition-edge sensor (TES) X-ray calorimeters.
We investigated the relationship between the noise, bias, and the superconducting phase …
