AGN outflows and the cluster cooling flow conundrum
, 2011 Temperature distributions within cores of galaxy clusters indicate gas in the core should cool down rapidly and contract. The cooling flow problem involves the hypothesis that the rapidly cooling gas should eventually condensate into unobserved molecular

Uncovering the First AGN Jets with AXIS
Jets powered by AGN in the early Universe (z≳6) have the potential to not only define the evolutionary trajectories of the first-forming massive galaxies but to enable the accelerated growth of their associated SMBHs.

A dichotomy in the orientation of dust and radio jets in nearby low-power radio galaxies
, 2005 We examine the properties of central dust in nearby quiescent and active early-type galaxies. The active galaxies are low-power radio galaxies with Fanaroff & Riley type I or I/II radio jets.

Radio jets in colliding galaxies: Testing the interaction-activity connection
, 1993 The idea that galaxy interactions and merging are related to the generation of starburst and AGN activity in galactic nuclei has been the subject of intensive investigations over the past several years and is still a matter of lively debate.

Kiloparsec-scale jets in FR I radio galaxies and the gamma-ray background
, 2006 We discuss the contribution of kiloparsec-scale jets in FR I radio galaxies to the diffuse γ-ray background radiation. The analyzed γ-ray emission comes from inverse-Compton scattering of starlight photon fields by the ultrarelativistic electrons whose ...

Towards AMR Simulations of Galaxy Formation [PDF]
, 2010 Numerical simulations present a fundamental building block of our modern theoretical understanding of the Universe. As such the work in this thesis is primarily concerned with understanding fundamental differences that lie between the different ...

What determines the properties of the X-ray jets in Fanaroff-Riley type I radio galaxies? [PDF]
, 2012 We present the first large sample investigation of the properties of jets in Fanaroff-Riley type I radio galaxies (FR I) based on data from the Chandra archive.

Relativistic Jets in Radio-Weak Quasars and LINER Galaxies
, 1997 : We discuss radio observations of a sample of radio-weak and radio-intermediate quasars which demonstrate that -- just like their radio-loud counterparts -- radioweak quasars too have relativistic jets in their nuclei.

Accretion supermassive black holes in the center of active galaxies usually produce “jet”-collimated bipolar outflows of relativistic particles. Magnetic fields near the black hole event horizon may play a crucial role in the formation of jets/outflows ...
