The Chinese Pulsar Timing Array data release I. Single pulsar noise analysis
The Chinese Pulsar Timing Array (CPTA) has collected observations from 57 millisecond pulsars using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST) for close to three years, for the purpose of searching for gravitational waves (GWs). To robustly search for ultra-low-frequency GWs, pulsar timing arrays (PTAs) need to use models to describe the noise from the individual pulsars. We report on the results from the single pulsar noise analysis of the CPTA data release I (DR1). Conve…

Axion Superradiance in Dipole Magnetic Fields of Pulsars
We consider constraints on the axion-photon coupling by superradiance due to a plasma instability in the magnetospheres of millisecond pulsars. We compute the growth rate of a superradiant axion cloud in a dipole magnetic field, and give a semi-analytical formula for the superradiance rate for the lowest state. By requiring the associated instability time to be longer than the characteristic age of the supermassive black-widow millisecond pulsar PSR J0952-0607, we examine the pulsar-timing arra…

Realistic assessment of a single gravitational wave source localization taking into account precise pulsar distances with pulsar timing arrays
Pulsar timing arrays (PTAs) are anticipated to detect continuous gravitational waves (GWs) from individual supermassive black hole binaries (SMBHBs) in the near future. To identify the host galaxy of a GW source, PTAs require significantly improved angular resolution beyond the typical range of 100-1000 square degrees achieved by recent continuous GW searches. In this study, we investigate how precise pulsar distance measurements can enhance the localization of a single GW source. Accurate dist…

MULTISS: un protocole de stockage confidentiel {à} long terme sur plusieurs r{é}seaux QKD
This paper presents MULTISS, a new protocol for long-term storage distributed across multiple Quantum Key Distribution (QKD) networks. This protocol is an extension of LINCOS, a secure storage protocol that uses Shamir secret sharing for secret storage on a single QKD network. Our protocol uses hierarchical secret sharing to distribute a secret across multiple QKD networks while ensuring perfect security. Our protocol further allows for sharing updates without having to reconstruct the entire s…

some guy is putting placards all over the Mission labeling sidewalk plants with their common and scientific name and a QR code to his vibe-coded AI landscaping service.
not only does he seem to have nothing to do with the planting of the plants, he can't tell which ones are weeds and has faithfully labeled a "Spiny sowthistle (Sonchus asper)" ahaha

Irradiated Pulsar Planets and Companions as 511 keV Positron Annihilation Line Sources
Millisecond pulsars (MSPs) are prolific GeV $γ\text{-ray}$ emitters, and nearly 80\% of Fermi-LAT MSPs reside in compact binaries. We demonstrate that the companions in these compact MSPs binaries are also 511 keV annihilation line emitters using {\tt MEGAlib} simulations (a high energy radiation transport software built with {\tt Geant4}) to compute the particle showers and resulting back splash emission from the pulsar irradiation. The 511 keV signal exhibits strong flux modulation and red/b…
