To a good approximation our Universe is flat and homogeneous, and possesses perturbations which, albeit once upon a time small, have seeded the large-scale structure that we observe around us. We believe this to be result ...
The Sunyaev-Zel'dovich Effect as a Probe of the Thermodynamics of Extragalactic Systems
(Johns Hopkins University, 2017-07-20)
The thermal Sunyaev-Zel’dovich effect is a spectral distortion of the Cosmic Microwave Background that enables the study of the thermal state of ionized gasin extragalactic systems. The magnitude of this effect is proportional ...
SEARCHING FOR QUASAR FEEDBACK IN OBSCURED AND RED QUASARS AT THE PEAK OF GALAXY FORMATION
(Johns Hopkins University, 2017-07-21)
Though small on the scale of their host galaxy, supermassive black holes likely play a crucial role in galaxy evolution. A galaxy-scale effect driven by supermassive black holes (or ``quasar feedback”) is necessary to stop ...
