We're going to need so much community and mutual aid to deal with the coming climate change reckoning combined with the complete abandonment by the US government. https://fed.brid.gy/r/https://bsky.app/profile/did:plc:f7utvjkqbgwfj…

First release of LiteBIRD simulations from an end-to-end pipeline
The LiteBIRD satellite mission aims at detecting Cosmic Microwave Background $B$ modes with unprecedented precision, targeting a total error on the tensor-to-scalar ratio $r$ of $δr \sim 0.001$. Operating from the L2 Lagrangian point of the Sun-Earth system, LiteBIRD will survey the full sky across 15 frequency bands (34 to 448 GHz) for 3 years.The current LiteBIRD baseline configuration employs 4508 detectors sampling at 19.1 Hz to achieve an effective polarization sensitivity of $ 2 μ\mathr…

Canada : "Le coût estimé pour l’achat de 88 nouveaux F-35A auprès des États‑Unis a explosé de près de 50 % depuis 2022"

MAGA doesn't give a damn about how stupid, insensitive or obnoxious they sound, much less whether anything they say is true.
If you voted for #Trump (or you didn't vote)... you're responsible for this.

Reliability of Capacitive Read in Arrays of Ferroelectric Capacitors
The non-destructive capacitance read-out of ferroelectric capacitors (FeCaps) based on doped HfO$_2$ metal-ferroelectric-metal (MFM) structures offers the potential for low-power and highly scalable crossbar arrays. This is due to a number of factors, including the selector-less design, the absence of sneak paths, the power-efficient charge-based read operation, and the reduced IR drop. Nevertheless, a reliable capacitive readout presents certain challenges, particularly in regard to device var…

A Simulation Framework for the LiteBIRD Instruments
LiteBIRD, the Lite (Light) satellite for the study of $B$-mode polarization and Inflation from cosmic background Radiation Detection, is a space mission focused on primordial cosmology and fundamental physics. In this paper, we present the LiteBIRD Simulation Framework (LBS), a Python package designed for the implementation of pipelines that model the outputs of the data acquisition process from the three instruments on the LiteBIRD spacecraft: LFT (Low-Frequency Telescope), MFT (Mid-Frequency …

On the computational feasibility of Bayesian end-to-end analysis of LiteBIRD simulations within Cosmoglobe
We assess the computational feasibility of end-to-end Bayesian analysis of the JAXA-led LiteBIRD experiment by analysing simulated time ordered data (TOD) for a subset of detectors through the Cosmoglobe and Commander3 framework. The data volume for the simulated TOD is 1.55 TB, or 470 GB after Huffman compression. From this we estimate a total data volume of 238 TB for the full three year mission, or 70 TB after Huffman compression. We further estimate the running time for one Gibbs sample, fr…
