Journal Article
Prasow-Émond, M., Hlavacek-Larrondo, J., Rhea, C., Latulippe, M., Gendron-Marsolais, M., Richard-Laferrière, A., …Linden, A. V. D. (2020). A Multiwavelength Study of the Cool Core Cluster MACS J1447.4+0827. Astronomical Journal, 160(3), Article 103. https://doi.org/10.3847/1538-3881/ab9ff3

Clusters of galaxies are outstanding laboratories for understanding the physics of supermassive black hole (SMBH) feedback. Here we present the first Chandra, Karl G. Jansky Very Large Array, and Hubble Space Telescope analysis of MACS J1447.4+0827 (... Read More about A Multiwavelength Study of the Cool Core Cluster MACS J1447.4+0827.

Thermally Unstable Cooling Stimulated by Uplift: The Spoiler Clusters (2020)
Journal Article
Martz, C., McNamara, B., Nulsen, P., Vantyghem, A., Gingras, M., Babyk, I. V., …Hogan, M. (2020). Thermally Unstable Cooling Stimulated by Uplift: The Spoiler Clusters. Astrophysical Journal, 897(1), Article 57. https://doi.org/10.3847/1538-4357/ab96cd

Chandra X-ray observations are analyzed for five galaxy clusters whose atmospheric cooling times, entropy parameters, and ratios of cooling time to freefall time within the central galaxies lie below 1 Gyr, below 30 keV cm2, and between 20 lesssim mi...

LOFAR observations of X-ray cavity systems (2020)
Journal Article
Shimwell, T., Röttgering, H., Morganti, R., Edge, A., Cuciti, V., Brunetti, G., …Bîrzan, L. (2020). LOFAR observations of X-ray cavity systems. Monthly Notices of the Royal Astronomical Society, 496(3), 2613-2635. https://doi.org/10.1093/mnras/staa1594

We present LOFAR observations at 120–168 MHz of 42 systems with possible X-ray cavities in their hot atmosphere, of which 17 are groups or ellipticals, 19 are nearby clusters (z < 0.3), and six are higher redshift clusters (z > 0.3). The X-ray caviti... Read More about LOFAR observations of X-ray cavity systems.

A molecular absorption line survey toward the AGN of Hydra-A (2020)
Journal Article
Peck, A., Oonk, J., O’Dea, C., Nesvadba, N., Ferland, G., Fabian, A., …Rose, T. (2020). A molecular absorption line survey toward the AGN of Hydra-A. Monthly Notices of the Royal Astronomical Society, 496(1), 364-380. https://doi.org/10.1093/mnras/staa1474

We present Atacama Large Millimeter/submillimeter Array observations of the brightest cluster galaxy Hydra-A, a nearby (z = 0.054) giant elliptical galaxy with powerful and extended radio jets. The observations reveal CO(1-0), CO(2-1), 13CO(2-1), CN(... Read More about A molecular absorption line survey toward the AGN of Hydra-A.

Decoherence in LOFAR-VLBI beamforming (2020)
Journal Article
Bonnassieux, E., Edge, A., Morabito, L., & Bonafede, A. (2020). Decoherence in LOFAR-VLBI beamforming. Astronomy & Astrophysics, 637, Article A51. https://doi.org/10.1051/0004-6361/202037486

We show that the use of a superstation (a phased array created using multiple stations of an interferometric array) created in post-processing for LOFAR-VLBI observations introduces a direction-dependent loss of signal in the image. We show this effe... Read More about Decoherence in LOFAR-VLBI beamforming.

Atacama Compact Array Measurements of the Molecular Mass in the NGC 5044 Cooling-flow Group (2020)
Journal Article
Schellenberger, G., David, L. P., Vrtilek, J., O’Sullivan, E., Lim, J., Forman, W., …Bardelli, S. (2020). Atacama Compact Array Measurements of the Molecular Mass in the NGC 5044 Cooling-flow Group. Astrophysical Journal, 894(1), Article 72. https://doi.org/10.3847/1538-4357/ab879c

The fate of cooling gas in the centers of galaxy clusters and groups is still not well understood, as is also the case for the complex processes of triggering star formation in central dominant galaxies, reheating of cooled gas by active galactic nuc...
