Compact, star-forming galaxies with high star formation rate surface densities (Σ SFR) are often efficient Lyman continuum (LyC) emitters at z ≤ 4.5, likely because intense stellar feedback creates low-density channels that allow photons to escape. Irregular or disturbed morphologies, such as those resulting from mergers, can also facilitate LyC

The process of active galactic nuclei (AGN) fuelling relies on the transport of gas across several orders of magnitude in physical scale until the gas reaches the supermassive black hole at the centre of a galaxy. This work explores the role of kinematically misaligned gas in the fuelling of AGN in a sample of 4769 local galaxies from the Mapping

The asteroid 2024 YR4 was discovered in late December 2024, and over the next several weeks as its orbit was refined its estimated probability of an Earth impact in 2032 rose above 3%. Per international protocols, the International Asteroid Warning Network (IAWN) issued a memo alerting the Space Mission Planning Advisory Group (SMPAG) and the

We report the discovery of a previously uncatalogued extended emission nebula, hereafter JAM 1, detected in ultra-deep [O III] and Hα narrowband imaging. Located at 18 h56 m25 s, + 30 ° 42 ' 06 ″ (J2000), JAM 1 exhibits a nearly spherical morphology with an angular diameter of ≈864″ ( 14 . ' 4 ). The object is conspicuous in [O III], while in Hα it

Aims. We present the white dwarf catalog derived from the third data release of the Javalambre Photometric Local Universe Survey (J-PLUS DR3), which covers 3284 deg 2 using 12 optical filters. A particular focus is given to the classification of outlier sources, those largely incompatible with the theoretical models used in the analysis, through

Primitive asteroids belonging to the C-complex groups are considered to be among the most ancient and least thermally altered bodies in the Solar System. They are thought to preserve a record of early Solar System conditions, including the primordial distribution of volatiles and organic compounds that may have played a role in the emergence of
