Journal Article
Mittal, R., Oonk, J. R., Ferland, G. J., Edge, A. C., O'Dea, C. P., Baum, S. A., …Russell, H. (2012). Herschel observations of extended atomic gas in the core of the Perseus cluster. Monthly Notices of the Royal Astronomical Society, 426(4), 2957-2977. https://doi.org/10.1111/j.1365-2966.2012.21891.x

We present Herschel observations of the core of the Perseus cluster of galaxies. Especially intriguing is the network of filaments that surround the brightest cluster galaxy, NGC 1275, previously imaged extensively in Hα and CO. In this work, we repo...

Discovery of radio haloes and double relics in distant MACS galaxy clusters: clues to the efficiency of particle acceleration (2012)
Journal Article
Bonafede, A., Brüggen, M., van Weeren, R., Vazza, F., Giovannini, G., Ebeling, H., …Klein, U. (2012). Discovery of radio haloes and double relics in distant MACS galaxy clusters: clues to the efficiency of particle acceleration. Monthly Notices of the Royal Astronomical Society, 426(1), 40-56. https://doi.org/10.1111/j.1365-2966.2012.21570.x

We have performed 323 MHz observations with the Giant Metrewave Radio Telescope of the most promising candidates selected from the MACS catalogue. The aim of the work is to extend our knowledge of the radio halo and relic populations to z > 0.3, the...

Diffuse radio emission in MACS J1752.0+4440 (2012)
Journal Article
van Weeren, R., Bonafede, A., Ebeling, H., Edge, A., Brüggen, M., Giovannini, G., …Röttgering, H. (2012). Diffuse radio emission in MACS J1752.0+4440. Monthly Notices of the Royal Astronomical Society: Letters, 425(1), L36-L40. https://doi.org/10.1111/j.1745-3933.2012.01301.x

We report the discovery of large-scale diffuse radio emission in the galaxy cluster MACS J1752.0+4440 (z = 0.366). Using Westerbork Synthesis Radio Telescope (WSRT) observations we find that the cluster hosts a double radio relic system as well as a... Read More about Diffuse radio emission in MACS J1752.0+4440.

LoCuSS: A Dynamical Analysis of X-Ray Active Galactic Nuclei in Local Clusters (2012)
Journal Article

Residual cooling and persistent star formation amid active galactic nucleus feedback in Abell 2597 (2012)
Journal Article
Tremblay, G., O'Dea, C., Baum, S., Clarke, T., Sarazin, C., Bregman, J., …Wise, M. (2012). Residual cooling and persistent star formation amid active galactic nucleus feedback in Abell 2597. Monthly Notices of the Royal Astronomical Society, 424(2), 1042-1060. https://doi.org/10.1111/j.1365-2966.2012.21278.x

New Chandra X-ray and Herschel Far-Infrared (FIR) observations enable a multiwavelength study of active galactic nucleus (AGN) heating and intracluster medium (ICM) cooling in the brightest cluster galaxy (BCG) of Abell 2597 (z= 0.0821). The new Chan... Read More about Residual cooling and persistent star formation amid active galactic nucleus feedback in Abell 2597.

Strong lensing by a node of the cosmic web. The core of MACS J0717.5+3745 at z = 0.55 (2012)
Journal Article
Limousin, M., Ebeling, H., Richard, J., Swinbank, A., Smith, G., Jauzac, M., …Kneib, J. (2012). Strong lensing by a node of the cosmic web. The core of MACS J0717.5+3745 at z = 0.55. Astronomy & Astrophysics, 544, Article A71. https://doi.org/10.1051/0004-6361/201117921

We present results of a strong-lensing analysis of MACS J0717.5+3745 (hereafter MACS J0717), an extremely X-ray luminous galaxy cluster at z = 0.55. Observations at different wavelengths reveal a complex and dynamically very active cluster, whose cor... Read More about Strong lensing by a node of the cosmic web.

Multiphase signatures of active galactic nucleus feedback in Abell 2597 (2012)
Journal Article
Tremblay, G., O'Dea, C., Baum, S., Clarke, T., Sarazin, C., Bregman, J., …Wise, M. (2012). Multiphase signatures of active galactic nucleus feedback in Abell 2597. Monthly Notices of the Royal Astronomical Society, 424(2), 1026-1041. https://doi.org/10.1111/j.1365-2966.2012.21281.x

We present new Chandra X-ray observations of the brightest cluster galaxy (BCG) in the cool-core cluster Abell 2597 (z= 0.0821). The data reveal an extensive kpc-scale X-ray cavity network as well as a 15-kpc filament of soft-excess gas exhibiting st...
