2-mm-Thick Large-Area CdTe Double-sided Strip Detectors for High-Resolution Spectroscopic Imaging of X-ray and Gamma-ray with Depth-Of-Interaction Sensing
Takahiro Minami, Miho Katsuragawa, Shunsaku Nagasawa +4
We developed a 2-mm-thick CdTe double-sided strip detector (CdTe-DSD) with a 250 um strip pitch, which has high spatial resolution with a uniform large imaging area of 10 cm an…
LiteBIRD Science Goals and Forecasts: Improving Sensitivity to Inflationary Gravitational Waves with Multitracer Delensing
T. Namikawa, A. I. Lonappan, C. Baccigalupi +119
We estimate the efficiency of mitigating the lensing -mode polarization, the so-called delensing, for the experiment with multiple external data sets of lensing-mass…
LiteBIRD Science Goals and Forecasts: A full-sky measurement of gravitational lensing of the CMB
A. I. Lonappan, T. Namikawa, G. Piccirilli +119
We explore the capability of measuring lensing signals in full-sky polarization maps. With a arcmin beam width and an impressively low polarization noise of $2.16\,…
High count rate effects in event processing for XRISM/Resolve x-ray microcalorimeter
Misaki Mizumoto, Masahiro Tsujimoto, Renata S. Cumbee +11
The spectroscopic performance of x-ray instruments can be affected at high count rates. The effects and mitigation in the optical chain, such as x-ray attenuation filters or de-foc…
Variational Mode Decomposition-Based Nonstationary Coherent Structure Analysis for Spatiotemporal Data
Yuya Ohmichi
The conventional modal analysis techniques face difficulties in handling nonstationary phenomena, such as transient, nonperiodic, or intermittent phenomena. This paper presents a v…
LiteBIRD Science Goals and Forecasts. A Case Study of the Origin of Primordial Gravitational Waves using Large-Scale CMB Polarization
P. Campeti, E. Komatsu, C. Baccigalupi +107
We study the possibility of using the satellite -mode survey to constrain models of inflation producing specific features in CMB angular power spectra. We explore a p…
