Some of the most extreme galactic black hole transients exhibit a nebular phase at the end of their outbursts. This stage was first identified in the 2015 outburst of V404 Cygni, when it dominated the optical spectrum for ~4 days. It is characterised by exceptionally strong optical emission lines, together with a significant increase in the Balmer

Aims. Leveraging the high-precision photometric redshifts of the Physics of the Accelerating Universe Survey (PAUS), we aim to investigate the connection between active galactic nuclei (AGNs) and galaxy pairs up to redshifts of ~1.0. Methods. We identified 16 824 galaxy pairs with projected separations of r p < 100 kpc and radial-velocity

The Middle Ages Galaxy Properties with Integral field spectroscopy (MAGPI) survey is a Large Program on the European Southern Observatory Very Large Telescope using the Multi Unit Spectroscopic Explorer (MUSE) instrument. This paper presents the data release for the MAGPI emission-line products and includes emission-line maps for 836 galaxies at $0

We report the first detection of the neutral methyl radical CH 3 in a highly evolved C-rich object, SMP LMC 011, using the Mid-Infrared Instrument (MIRI) Medium-Resolution Spectrometer (MRS) on JWST. CH 3 is well fitted by an excitation temperature of T ex ≃ 190 K and a column density of N tot(CH 3) ≃ 5.6 × 10 17 cm -2. We also report the

Context. Massive stars play a fundamental role in the evolution of the Universe, yet several physical processes governing their evolution remain poorly constrained. Notably, the main-sequence width is known to be sensitive to the convective boundary mixing efficiency. Moreover, discrepancies between single-star evolution predictions and
