Final assessment of radioactive impurities in the JUNO detector

Thomas Adam, Fengpeng An, Costas Andreopoulos, Giuseppe Andronico et autres

The Jiangmen Underground Neutrino Observatory (JUNO) collaboration has completed the construction of the 20,000-ton liquid scintillator detector and the associated muon veto detector system. To meet the physics objectives, the materials used in the detector must exhibit low radioactive contamination. The single-event …

A Low-energy Threshold and Multi-messenger Trigger System for the JUNO Experiment

Thomas Adam, Fengpeng An, Costas Andreopoulos, Giuseppe Andronico et autres

The Jiangmen Underground Neutrino Observatory (JUNO) is a 20-kiloton liquid scintillator neutrino detector, located 650 meters (1800 m.w.e.) underground in Jiangmen, Guangdong, China. JUNO is primarily designed for reactor neutrino measurements and has been taking data since 2025. With the largest mass …

Commensal image plane transient search methods with the SKAO

Alex Andersson, Dougal Dobbie, Natasha Hurley-Walker, Hao Qiu et autres

This chapter outlines the key, state of the art, techniques required to conduct commensal image plane transient searches. Using significant experience and expertise from conducting transient searches with the SKA pathfinders, we have developed efficient fast imaging strategies, automated transient detection pipelines, …

SMGPS: A study of Galactic HII regions with extended morphology

Athanaseus J. T. Ramaila, Mark Thompson, O Smirnov, Sphesihle Makhathini et autres

We present a study of ionised hydrogen ($\textrm{H}\scriptstyle\mathrm{II}$) regions in the Galactic Plane using data from the SARAO MeerKAT Galactic Plane Survey (SMGPS). The SMPGS is a wide-field, wide-band 1.3 GHz radio continuum survey ($251^\circ \leq l \leq 358^\circ$ and $2^\circ \leq …

Fast Simultaneous Surveys with On-the-Fly Mapping

Suman Chatterjee, Sarvesh Mangla, Sourabh Paul, K. Grainge et autres

The SKAO is a next-generation radio telescope that will transform our understanding of the formation and evolution of radio galaxies, quasars, transients, and other cosmic sources. Surveys conducted on precursor telescopes can inform us about the capabilities and challenges to be overcome …

The 10-15 GHz radio continuum survey of the Galactic Plane with SKAO

A. Traficante, C. Mininni, F. Cavallaro, G. Umana et autres

Star formation emerges from the complex interplay between gravity, turbulence, magnetic fields, and stellar feedback, all of which vary across spatial scales and Galactic environments. Over the past decades, extensive multiwavelength surveys of the Galactic Plane have progressively unveiled this complexity. Far-infrared …

Tracing Large-scale Structure with the MeerKLASS On-the-Fly Survey: Angular Clustering of Radio Sources at 816 MHz

Sourabh Paul, Suman Chatterjee, K. Grainge, Laura Wolz et autres

We present the first measurement of the angular two-point correlation function \(w(θ)\) of radio sources from the MeerKAT Large Area Synoptic Survey (MeerKLASS) UHF on-the-fly (OTF) continuum Data Release~1. DR1 provides interferometric Stokes-\(I\) imaging at a reference frequency of 816\,MHz over \(\sim …

Cosmic dance in the Shapley Concentration Core II. The uGMRT-MeerKAT view of filaments in the brightest cluster galaxies and tailed radio galaxies in the A3528 cluster complex

G. Di Gennaro, T. Venturi, S. Giacintucci, M. Brüggen et autres

Superclusters are the largest-scale environments where a number of galaxy clusters interact with each other through minor/major mergers and grow via accretion along cosmic filaments. We focus on the A3528 complex in the core of the Shapley Supercluster. This system includes three …

Lossy Compression of Large-Scale Radio Interferometric Data

M Atemkeng, S Perkins, E Seck, S Makhathini et autres

This work proposes to reduce visibility data volume using a baseline-dependent lossy compression technique that preserves smearing at the edges of the field-of-view. We exploit the relation of the rank of a matrix and the fact that a low-rank approximation can describe …
