The generation and transformation of polarisation signals in molecular lines through collective anisotropic resonant scattering

Martin Houde, Boy Lankhaar, Fereshteh Rajabi +1

We discuss the existence of elliptical polarisation in rotational spectral lines of CO and other molecules within the context of the Anisotropic Resonant Scattering (ARS) model. We…

Discovery of Strongly Lensed Quasars in the Ultraviolet Near Infrared Optical Northern Survey (UNIONS)

J. H. H. Chan, C. Lemon, F. Courbin +13

We report the discovery of five new doubly-imaged lensed quasars from the first 2500 square degrees of the ongoing Canada-France Imaging Survey (CFIS), which is a component of the…

Event Horizon Telescope observations of the jet launching and collimation in Centaurus A

Michael Janssen, Heino Falcke, Matthias Kadler +236

Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…

Dynamics and Morphology of Cold Gas in Fast, Radiatively Cooling Outflows: Constraining AGN Energetics with Horseshoes

Yu Qiu, Haojie Hu, Kohei Inayoshi +3

Warm ionized and cold neutral outflows with velocities exceeding are commonly observed in galaxies and clusters. Theoretical studies however indicate that r…

Tracing satellite planes in the Sculptor group: I. Discovery of three faint dwarf galaxies around NGC 253

David Martinez-Delgado, Dmitry Makarov, Behnam Javanmardi +7

In the last years, a new generation of large-scale imaging surveys have probed wide field regions around some nearby galaxies at unprecedented low surface brightness regime (~28.0-…

Convolutional neural network identification of galaxy post-mergers in UNIONS using IllustrisTNG

Robert W. Bickley, Connor Bottrell, Maan H. Hani +6

The Canada-France Imaging Survey (CFIS) will consist of deep, high-resolution r-band imaging over ~5000 square degrees of the sky, representing a first-rate opportunity to identify…
