Spectroscopic Analysis of Fermi-detected Blazars using SDSS-V

Mohammed Iddrisu Nlowie, James Aird, Eli Kasai +17

The automated spectroscopic pipeline of the Sloan Digital Sky Survey (SDSS) systematically assigns Galactic star, galaxy, or typical quasar classifications to jet-dominated blazars…

The Twentieth Data Release of the Sloan Digital Sky Survey: First All-Sky BOSS Spectra, eROSITA-SDSS-V Mapper Coordinated Observations, and a Preview of the Local Volume Mapper

SDSS Collaboration, Mojgan Aghakhanloo, David Aguilar +273

This paper presents the twentieth data release (DR20) from the Sloan Digital Sky Survey, the third data release of its fifth generation (SDSS-V). SDSS-V is a panoptic spectroscopy…

SDSS-V: Revealing a weak accretion state in X-ray selected red quasars

Paloma Guetzoyan, James Aird, Amy L. Rankine +17

Red quasars (rQSOs) have been recognized as a short-lived, early stage in the evolutionary cycle of Active Galactic Nuclei (AGN), with fundamental differences in their intrinsic pr…

The Nineteenth Data Release of the Sloan Digital Sky Survey

SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210

Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…

Large-scale dual AGN in large-scale cosmological hydrodynamical simulations

Clara Puerto-Sánchez, Melanie Habouzit, Marta Volonteri +10

Detecting dual active galactic nuclei (DAGN) in observations and understanding theoretically which massive black holes (MBHs) compose them and in which galactic and large-scale env…

X-ray AGN in Boötes: The lack of growth of the most massive black holes since z=4

Paloma Guetzoyan, James Aird, Antonis Georgakakis +5

Supermassive Black Holes (BHs) are known to efficiently grow through gas accretion, but even sustained and intense mass build-up through this mechanism struggles to explain the ass…

VLT/MUSE Characterisation of Dimorphos Ejecta from the DART Impact

Brian P. Murphy, Cyrielle Opitom, Colin Snodgrass +8

We have observed the Didymos-Dimorphos binary system with the MUSE integral field unit spectrograph mounted at the Very Large Telescope (VLT) pre and post-DART impact, and captured…
