Emergent gravity and Dark Energy
T. Padmanabhan
This is an invited contribution to be included in a multi-authored book on "Dark Energy", to be edited by Pilar Ruiz-Lapuente and published by Cambridge University Press.
Properties of High Redshift Quasars-I: Evolution of the super-massive black-hole to halo mass ratio
Stuart Wyithe, T. Padmanabhan
In the local universe, the masses of Super-Massive Black-Holes (SMBH) appear to correlate with physical properties of their hosts, including the mass of the dark-matter halos. At h…
Thermodynamics and/of Horizons: A Comparison of Schwarzschild,RINDLER and desitter Spacetimes
T. Padmanabhan
The notions of temperature, entropy and `evaporation', usually associated with spacetimes with horizons, are analyzed using general approach and the following results, applicable t…
A simple analytical model for the abundance of damped Ly-αabsorbers
T. Roy Choudhury, T. Padmanabhan
A simple analytical model for estimating the fraction (Ω_{gas}) of matter in gaseous form within the collapsed dark matter (DM) haloes is presented. The model is developed using (i…
Hypothesis of path integral duality: Applications to QED
S. Shankaranarayanan, T. Padmanabhan
We use the modified propagator for quantum field based on a ``principle of path integral duality" proposed earlier in a paper by Padmanabhan to investigate several results in QED.…
