A hot core in the group-dominant elliptical galaxy NGC 777
Ewan O'Sullivan, Kamlesh Rajpurohit, Gerrit Schellenberger +8
NGC 777 provides an example of a phenomenon observed in some group-central ellipticals, in which the temperature profile shows a central peak, despite the short central cooling tim…
The formation channels of multiphase gas in nearby early-type galaxies
Ryan Eskenasy, Valeria Olivares, Yuanyuan Su +1
The processes responsible for the assembly of cold and warm gas in early-type galaxies (ETGs) are not well-understood. We report on the multiwavelength properties of 15 non-central…
The composition and thermal properties of a cool core lacking a brightest cluster galaxy
Yuanyuan Su, Francoise Combes, Valeria Olivares +3
We present a multiwavelength observation of a cool core that does not appear to be associated with any galaxy, in a nearby cluster, Abell~1142. Its X-ray surface brightness peak of…
The Nature of the Motions of Multiphase Filaments in the Centers of Galaxy Clusters
Shalini Ganguly, Yuan Li, Valeria Olivares +6
The intracluster medium (ICM) in the centers of galaxy clusters is heavily influenced by the ``feedback'' from supermassive black holes (SMBHs). Feedback can drive turbulence in th…
Spatially-resolved properties of early-type group-dominant galaxies with MUSE: gas content, ionisation mechanisms and metallicity gradients
P. Lagos, S. I. Loubser, T. C. Scott +6
With the goal of a thorough investigation of the ionised gas and its origin in early-type group-dominant galaxies, we present archival MUSE data for 18 galaxies from the Complete L…
AGN feedback duty cycle in Planck SZ selected clusters using Chandra observations
V. Olivares, Y. Su, P. Nulsen +5
We present a systematic study of X-ray cavities using archival Chandra observations of nearby galaxy clusters selected by their Sunyaev-Zel'dovich (SZ) signature in the Planck surv…
