The OPERA neutrino oscillation experiment has been designed to prove the appearance of ντ in a nearly pure νμbeam (CNGS) produced at CERN and detected underground Hall C Gran Sasso Laboratory, 730 km away from source. In OPERA, τ leptons resulting interaction ντare target units called bricks made nuclear emulsion films interleaved with lead plates. contains 150000 such bricks, for total mass 1.25 kton, arranged into walls plastic scintillator strips. detector is split two identical...
The conclusions of the Physics Working Group international scoping study a future Neutrino Factory and super-beam facility (the ISS) are presented. ISS was carried by community between NuFact05, 7th International Workshop on Factories Superbeams, Laboratori Nazionali di Frascati, Rome, June 21-26, 2005) NuFact06 (Ivine, California, 24{30 August 2006). physics case for an extensive experimental programme to understand properties neutrino is presented role high-precision measurements...
We present jax-cosmo, a library for automatically differentiable cosmological theory calculations. It uses the JAX library, which has created new coding ecosystem, especially in probabilistic programming. As well as batch acceleration, just-in-time compilation, and automatic optimization of code different hardware modalities (CPU, GPU, TPU), exposes an differentiation (autodiff) mechanism. Thanks to autodiff, jax-cosmo gives access derivatives likelihoods with respect any their parameters,...
This document reports on a series of experimental and theoretical studies conducted to assess the astro-particle physics potential three future large-scale particle detectors proposed in Europe as next generation underground observatories. The apparatus employ different and, some extent, complementary detection techniques: GLACIER (liquid Argon TPC), LENA scintillator) MEMPHYS (\WC), based use large mass liquids active media. results these are presented along with critical discussion...
Large Scale Structures (LSS) in the universe can be traced using neutral atomic hydrogen HI through its 21cm emission. Such a 3D matter distribution map used to test Cosmological model and constrain Dark Energy properties or equation of state. A novel approach, called intensity mapping distribution, radio interferometers with large instantaneous field view waveband. In this paper, we study sensitivity different interferometer configurations, multi-beam instruments for observation scale...
Fink is a broker designed to enable science with large time-domain alert streams such as the one from upcoming Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). It exhibits traditional astronomy features automatised ingestion, annotation, selection redistribution promising alerts for transient science. also go beyond by providing real-time classification which continuously improved using state-of-the-art Deep Learning Adaptive techniques. These evolving added values will more...
The Core Cosmology Library (CCL) provides routines to compute basic cosmological observables a high degree of accuracy, which have been verified with an extensive suite validation tests. Predictions are provided for many quantities, including distances, angular power spectra, correlation functions, halo bias and the mass function through state-of-the-art modeling prescriptions available in literature. Fiducial specifications expected galaxy distributions Large Synoptic Survey Telescope...
The Tianlai Dish Pathfinder Array is a radio interferometer designed to test techniques for 21~cm intensity mapping in the post-reionization universe as means measuring large-scale cosmic structure. It performs drift scans of sky at constant declination. We describe design, calibration, noise level, and stability this instrument based on analysis about $\sim 5 \%$ 6,200 hours on-sky observations through October, 2019. Beam pattern determinations using drones transit bright sources are good...
The OPERA neutrino detector at the underground Gran Sasso Laboratory (LNGS) was designed to perform first detection of oscillations in appearance mode, through study νμ → ντ oscillations. apparatus consists a lead/emulsion-film target complemented by electronic detectors. It is placed high-energy, long-baseline CERN LNGS beam (CNGS) 730 km away from source. In August 2006, run with CNGS neutrinos successfully conducted. A sample events collected, statistically consistent integrated...
This document summarizes the work of Accelerator Working Group (AWG) International Scoping Study (ISS) a Future Neutrino Factory and Superbeam Facility. The main goal activity was to reach consensus on baseline design for complex, including proton driver parameters, choice target, front-end design, acceleration system decay ring geometry. Another explore commonality, if any, between those or Beta Beam facility. In general, requirements either latter facilities are less stringent than...
From data accumulated over 6140 h with 172 g of enriched molybdenum (1.18 mol yr 100Mo) the NEMO 2 detector in Fréjus Underground Laboratory, a clear ββ2ν signal (1433 events) is observed, leading to half-life T1/2=0.95±0.04(stat)±0.09(syst) 1019 yr. The experimental two-electron energy spectrum and angular distribution are agreement expected ones. Limits for ββ0ν decays ground state, excited states (2+1 0+1), also Majoron emission given.Received 29 June...
The rapidly increasing statistical power of cosmological imaging surveys requires us to reassess the regime validity for various approximations that accelerate calculation relevant theoretical predictions. In this paper, we present results 'N5K non-Limber integration challenge', goal which was quantify performance different approaches calculating angular spectrum galaxy number counts and cosmic shear data without invoking so-called 'Limber approximation', in context Rubin Observatory Legacy...
