Published in #MNRAS: "The Quasar Feedback Survey: zooming into the origin of radio emission with e-MERLIN", Njeri et al. This is Fig. 9: for the caption & to read the paper please visit academic.oup.com/mnras/articl... @royalastrosoc.bsky.social
The four targets with the most clearly defined jetted emission, which enable common jet properties to be derived. The top row shows the VLA 6 GHz images, where the blue contours are from the e-MERLIN natural-weighted images. The VLA 6 GHz images are represented by red contours in all panels. The middle row shows the natural-weighted e-MERLIN images and the bottom row shows the e-MERLIN tapered images. The components used for calculations are labelled in the middle row (see Section 4.3).

Our latest paper explores the connection between radio spectral slopes and dust extinction in quasars using data from the uGMRT 📡

Connection between steep radio spectral slopes and dust extinction in QSOs: evidence for outflow-driven shocks in dusty QSO
Recent studies have found a striking positive correlation between the amount of dust obscuration and enhanced radio emission in quasi-stellar objects (QSOs). However, what causes this connection remai...

What drives radio emission in the faintest radio-quiet quasars? Are these radio-AGN quasars distinct from other similar compact radio sources?
Ann Njeri and collaborators present the highest-ever spatial resolution radio studies of these targets: e-merlin.ac.uk/news.html#QFS

New Blog Post! Two new papers: How do powerful supermassive black holes impact upon molecular gas? blogs.ncl.ac.uk/astro-obs/20...
Multi-panel plot showing two galaxies. In the top row we see maps, colour-coded by velocity (blue-red). These show central molecular gas disks, but also filamentary molecular gas structures. These structures are found along, and around the contours, which represent the radio emission. This reveals that the molecular gas is being entrained by expanding radio lobes. The bottom panels show CO emission-line profiles, extracted from the central regions of the galaxies. These show high velocity components, expected to be associated with outflowing gas.

Huge congrats to Newcastle Astro-Obs researcher Carola Zanoletti whose first paper is out on the arXiv today! Go read it here: arxiv.org/abs/2310.19871

In it she and her collaborators explore effects of 4D Einstein-Gauss-Bonnet gravity and constrain an untested area of its parameter space!
Present-day (z = 0) linear matter power spectrum for small-α 4DEGB model. The middle (solid black) curve is the power spectrum for a ΛCDM model. The dotted (green) and dash-double dotted (gray) curves show the ΛCDM+Neff model with Neff = 5.46 and 0.62 respectively.
