High-spectral-resolution Observations of the [S II] Emission-line Doublet in the Filamentary Nebula Surrounding NGC 1275

Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +10

We analyze new high-spectral resolution SITELLE observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, central galaxy of the Perseus cluster. We present h…

Magnetised CGM Gas at z~1 revealed by SPICE-RACS

Sunil Malik, S. P. O'Sullivan, A. J. M. Thomson +17

Magnetic fields are expected to permeate the circumgalactic medium (CGM) of galaxies, yet direct constraints at high redshift remain limited by the lack of high-quality Faraday rot…
