The dataset comprises astronomical observations of celestial sources, primarily quasars and active galactic nuclei, characterized by their radio emissions. It includes precise coordinates, observation frequencies ranging from 336.99 to 352.99 GHz, dates, and associated metadata such as source identifiers and measurement parameters. Designed for astrophysical research, the dataset supports studies on the distribution, luminosity, and evolutionary characteristics of high-redshift objects. By compiling detailed observational data, it aids in understanding the role of supermassive black holes in galaxy formation and the large-scale structure of the universe. The entries are part of a broader effort to map radio-loud sources, providing a resource for analyzing cosmic phenomena through multi-wavelength observations.

Quasars, powered by supermassive black holes, are among the brightest objects in the Universe. In the vicinity of a supermassive black hole, X-ray photons from an active galactic nucleus can heat the surrounding gas to several hundred kelvin. Here we report observations of dust continuum and carbon ...

The physical conditions of the circumgalactic medium are investigated by means of intervening absorption-line systems in the spectrum of background quasi-stellar objects (QSOs) out to the epoch of cosmic reionization1–4. A correlation between the ionization state of the absorbing gas and the nature ...

High-mass stars form in protoclusters, where gravo-magnetic processes elongate collapsing clouds and clumps preferentially perpendicular to magnetic (B) fields. Yet it remains unclear whether gravo-magnetic processes still govern the formation of 0.01-pc-scale condensations in massive star-forming p...

Complex organic molecules (COMs), which are the seeds of prebiotic material and precursors of amino acids and sugars, form in the icy mantles of circumstellar dust grains1 but cannot be detected remotely unless they are heated and released to the gas phase. Around solar-mass stars, water and COMs on...

The discovery of wide-orbit giant exoplanets has posed a challenge to our conventional understanding of planet formation through the coagulation of dust grains and planetesimals and the subsequent accretion of protoplanetary disk gas. As an alternative mechanism, the direct in situ formation of plan...

Galaxy clusters are the most massive gravitationally bound structures in the Universe, comprising thousands of galaxies and pervaded by a diffuse, hot intracluster medium (ICM) that dominates the baryonic content of these systems. The formation and evolution of the ICM across cosmic time1 is thought...

Almost all massive stars have bound stellar companions, existing in binaries or higher-order multiples1–5. While binarity is theorized to be an essential feature of how massive stars form6, essentially all information about such properties is derived from observations of already formed stars, whose ...

Lyman-α blobs (LABs) are spatially extended nebulae of emission in the Lyman-α (Lyα) line of hydrogen, seen at high redshifts1,2, and most commonly found in the dense environment of star-forming galaxies3,4. A recent study showed that nearly 100% of the sky is covered by Lyα emission around high-red...

Stellar multiple systems play a pivotal role in cluster dynamics and stellar evolution, producing intense astronomical phenomena like X-ray binaries, gamma-ray bursts, type Ia supernova and stellar mergers, which are prime sources of gravitational waves. However, their origin remains poorly understo...

Angular momentum removal is a fundamental requirement for star and planet formation, yet the mechanisms driving this process remain debated. Magnetohydrodynamic disk winds, launched along magnetic field lines from extended disk regions, offer a promising solution, particularly in regions where magne...

Recent exoplanet studies have revealed that the orbital planes of planets are not always aligned with one another or with the equatorial plane of the central star. The misalignment has been ascribed to gravitational scattering by giant planets and/or companion stars1–3 or to fly-bys in stellar clust...

Accretion disks are an essential component in the paradigm of the formation of low-mass stars. Recent observations further identify disks surrounding low-mass pre-main-sequence stars perturbed by flybys. Whether disks around more massive stars evolve in a similar manner has become an urgent question...

The dominant mechanism forming multiple stellar systems in the high-mass regime (M* ≳ 8 M⊙) remained unknown because direct imaging of multiple protostellar systems at early phases of high-mass star formation is very challenging.
