Black Hole Motion as Catalyst of Orbital Resonances
C. M. Boily, T. Padmanabhan, A. Paiement
The motion of a black hole about the centre of gravity of its host galaxy induces a strong response from the surrounding stellar population. We treat the case of a harmonic potenti…
Response of distance measures to the equation of state
Tarun Deep Saini, T. Padmanabhan, Sarah Bridle
We show that the distance measures (such as the luminosity and angular diameter distances) are linear functionals of the equation-of-state function w(z) of the dark energy to a fai…
The effects of anti-correlation on gravitational clustering
Nissim Kanekar, T. Padmanabhan
We use non-linear scaling relations (NSRs) to investigate the effects arising from the existence of negative correlations on the evolution of gravitational clustering in an expandi…
Nonlinear density evolution from an improved spherical collapse model
S. Engineer, Nissim Kanekar, T. Padmanabhan
We investigate the evolution of non-linear density perturbations by taking into account the effects of deviations from spherical symmetry of a system. Starting from the standard sp…
Pattern in Nonlinear Gravatational Clustering: A Numerical Investigation
T. Padmanabhan, Renyue Cen, Jeremiah P. Ostriker +1
The nonlinear clustering of dark matter particles in an expanding universe is usually studied by N-body simulations. One can gain some insight into this complex problem if simple r…
