Radiative Feedback from Quasars and the Growth of Supermassive Black Holes
S. Yu. Sazonov, J. P. Ostriker, L. Ciotti +1
We discuss the role of feedback via photoionization and Compton heating in the co-evolution of massive black holes at the center of spheroidal galaxies and their stellar and gaseou…
A physically motivated toy model for the BH-spheroid coevolution
L. Ciotti, J. P. Ostriker, S. Yu. Sazonov
We present a summary of the results obtained with a time-dependent, one-zone toy model aimed at exploring the importance of radiative feedback on the co-evolution of massive black…
The current status of observational cosmology
Jeremiah P. Ostriker, Tarun Souradeep
Observational cosmology has indeed made very rapid progress in recent years. The ability to quantify the universe has largely improved due to observational constraints coming from…
Signatures of Galactic Superwinds: Inhomogeneous Metal Enrichment of the Lyman Alpha Forest
Renyue Cen, Kentaro Nagamine, Jeremiah P. Ostriker
We investigate possible signatures of feedback from galactic superwinds on the metallicity of the Lyman alpha forest, using a set of high resolution hydrodynamic simulations of a L…
Active Galaxies and Radiative Heating
J. P. Ostriker, L. Ciotti
There is abundant evidence that heating processes in the central regions of elliptical galaxies has both prevented large-scale cooling flows and assisted in the expulsion of metal…
Fast Identification of Bound Structures in Large N-body Simulations
Jochen Weller, Jeremiah P Ostriker, Paul Bode +1
We present an algorithm which is designed to allow the efficient identification and preliminary dynamical analysis of thousands of structures and substructures in large N-body simu…
