The impact of radio feedback from active galactic nuclei in cosmological simulations: Formation of disk galaxies
Takashi Okamoto, Rodrigo S. Nemmen, Richard G. Bower
In this paper, we present a new implementation of feedback due to active galactic nuclei (AGN) in cosmological simulations of galaxy formation. We assume that a fraction of jet ene…
Models for jet power in elliptical galaxies: A case for rapidly spinning black holes
Rodrigo S. Nemmen, Richard G. Bower, Arif Babul +1
The power of jets from black holes are expected to depend on both the spin of the black hole and the structure of the accretion disk in the region of the last stable orbit. We inve…
Radiatively Inefficient Accretion Flow in the Nucleus of NGC 1097
Rodrigo S. Nemmen, Thaisa Storchi-Bergmann, Feng Yuan +3
We present a model for the accretion flow around the supermassive black hole in the LINER nucleus of NGC 1097 which fits the optical to X-ray spectral energy distribution (SED). Th…
Evidence for a Starburst within 9 pc of the Active Nucleus of NGC 1097
T. Storchi-Bergmann, R. S. Nemmen, P. F. Spinelli +4
We report evidence for a recent burst of star formation located within 9 pc of the active nucleus of NGC 1097. The observational signatures of the starburst include UV absorption l…
The Ionizing Source of the Nucleus of NGC1097
R. S. Nemmen, T. Storchi-Bergmann, M. Eracleous +2
We present new observations in X-ray and optical/ultraviolet of the nucleus of NGC1097, known for the abrupt appearance of broad, double-peaked Balmer lines in its spectrum in 1991…
