TL;DR: HolMES as discussed by the authors is a new experiment to directly measure the neutrino mass using a calorimetric measurement of the energy released in the decay of 163Ho nuclei, which eliminates systematic uncertainties arising from the use of external beta sources.

TL;DR: LiteBIRD as discussed by the authors is a large-scale transition-edge sensors (TES) mission with a total wide frequency coverage between 34GHz and 448GHz, targeting its launch in Japanese Fiscal Year 2027 (2027FY) with JAXA's H3 rocket, which will accommodate more than 4000 TESs in focal planes of reflective low-frequency and refractive medium-and high-frequency telescopes.

Array-compatible transition-edge sensor microcalorimeter γ-ray detector with 42 eV energy resolution at 103 keV
Barry L. Zink,J. N. Ullom,J. A. Beall,Kent D. Irwin,William B. Doriese,W. D. Duncan,L. Ferreira,Gene C. Hilton,Robert D. Horansky,C. D. Reintsema,Leila R. Vale +10 more
TL;DR: In this article, a microcalorimeter γ-ray detector with measured energy resolution of 42eV full width at half maximum for 103keV photons is described. But the results of a detailed characterization of the detector, which includes measurements of the complex impedance, detector noise, and time-domain pulse response, suggest that a deeper understanding and optimization of the thermal transport between the absorber and thermometer could significantly improve the energy resolution.
