AGN jet-driven stochastic cold accretion in cluster cores
Deovrat Prasad, Prateek Sharma, Arif Babul
Several arguments suggest that stochastic condensation of cold gas and its accretion onto the central supermassive black hole (SMBH) is essential for active galactic nuclei (AGN) f…
Mpc-scale diffuse radio emission in two massive cool-core clusters of galaxies
Martin W. Sommer, Kaustuv Basu, Huib Intema +4
Radio halos are diffuse synchrotron sources on scales of ~1 Mpc that are found in merging clusters of galaxies, and are believed to be powered by electrons re-accelerated by the me…
The PAndAS view of the Andromeda satellite system - II. Detailed properties of 23 M31 dwarf spheroidal galaxies
Nicolas F. Martin, Rodrigo A. Ibata, Geraint F. Lewis +15
We present a comprehensive analysis of the structural properties and luminosities of the 23 dwarf spheroidal galaxies that fall within the footprint of the Pan-Andromeda Archaeolog…
The extended disc and halo of the Andromeda galaxy observed with Spitzer-IRAC
Masoud Rafiei Ravandi, Pauline Barmby, Matthew L. N. Ashby +6
We present the first results from an extended survey of the Andromeda galaxy (M31) using 41.1 h of observations by Spitzer-IRAC at 3.6 and 4.5m. This survey extends previous o…
